Water Quality BMPs
Water Quality Best Management Practices (BMPs) are vegetative, structural, and other measures that
reduce or eliminate pollutants that might otherwise be carried by surface runoff. Potential pollutant
sources include litter form patrons and automobile fluids on the pavement including heavy metals, oil,
grease, and alcohols. The stormwater for the site drains via sheet flow to a proposed storm network
that discharges into an interim detention basin prior to releasing into existing storm sewer
infrastructure within 3rd Avenue SW. The vegetated basin allows pollutants and sediment to settle out
prior to stormwater leaving the detention area.
BMPs for Carmel Midtown Development Parcel A will include:
Stormwater Inlet Structures
Topsoil, seed, and mulch on all unpaved disturbed areas
Hydrodynamic Separators
Underground Detention with Treatment Row
Outdoor Synthetic Turf
Dog Waste Stations
See Attachment A for a BMP Location Map for this project.

Address: 941 N. Meridian Street, Indianapolis, Indiana 46204
Business Phone Number: (317) 554-6732
Party Responsible
The BMP owner agrees to pay all the fees required by the City of Carmel, including annual inspection
fees, and/or any additional fees required. Routine inspections are the responsibility of the BMP owner.
Maintenance is also the responsibility of the owner. The City of Carmel must be notified of any changes
in BMP ownership, major repairs, or BMP failures in writing within 30 days. The letter should be
addressed to:
Storm Water Program
Carmel Engineering Dept.
One Civic Square
Carmel, IN 46032
In the event that the City of Carmel finds a BMP in need of maintenance or repair, the City of Carmel will
notify the BMP owner of the necessary maintenance or repairs and give the BMP Owner a timeframe for
completing the maintenance or repairs. If the maintenance or repairs are not completed within the
designated timeframe, the City shall perform the repairs or maintenance and bill the BMP Owner the
actual cost of the work.
Submittal of annual inspection reports to the City of Carmel Engineering are due one year after
construction is completed, with subsequent reports due each year within the same month of the initial
report, any deficiencies found during the inspections should be addressed, and the BMP owner faces
enforcement action from the City if the inspection report is not received within the month it is due, if
there are deficiencies which were not included in the report, or if any deficiencies included in the report
are not addressed in a timely manner.
Material Handling
Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with federal,
state, and local regulations. Removed sediment must be handled and disposed of in the garbage as solid
waste. Water should be disposed of in a sanitary sewer after oils are removed using oil absorbent
materials or other mechanical means. Used oil absorbents should be recycled or disposed according to
the manufacturer’s instructions.
Safety
Work inside underground structures requires special OSHA-required confined space equipment and
procedures. The most practical option to perform maintenance or repairs is to contract with a sewer-
cleaning contractor
Storm Structure Maintenance and Inspection
Storm structures on site are identified within the construction plans set. Storm structures are set at
storm sewer pipe connections. Unless you have OSHA approved training and equipment, never enter a
manhole. Inspection and maintenance of all storm structures is required per the table below.
Storm Structure Maintenance and Inspection
Inspection All inlet castings should be inspected every 6 months and after
each major rainfall event. More frequent inspections should be
performed in areas where there is higher potential for trash or
litter and during the fall when leaves are present on the ground.
Check the frame and lid for cracks and wear, such as rocking lids
or lids moved by traffic.
Storm structures and the surrounding areas should be inspected
annually for pollutants such as leaks from dumpsters, minor
spills, and oil dumping. Take action to have the pollutant source
removed.
Cleaning Clean structures when there is a blockage of a water flow path
or when sediment depth reaches 10% of the pipe diameter.
Cleaning should be performed in a way that ensures removed
sediment and water is not discharged back into the storm sewer.
Materials Handling Disposal of waste from maintenance of drainage facilities shall
be conducted in accordance with federal, state, and local
regulations. Removed sediment must be disposed in the garbage
as solid waste. Water should be disposed of in a sanitary sewer
after oils are removed using oil absorbent materials or other
mechanical means. Used oil absorbents should be recycled or
disposed according to the manufacturer's instructions.
Repairs Repair all security and access features so they are fully
functional. This includes locking lids, covers, and ladder rungs.
Replace broken parts or lids that rock or are moved by traffic.
Storm Sewer Maintenance and Inspection
Storm sewer pipes convey stormwater. Pipes are built from many materials and are sometimes
perforated to allow stormwater to infiltrate into the ground. Storm pipes are cleaned to remove
sediment or blockages when problems are identified. Storm pipes must be clear of obstructions and
breaks to prevent localized flooding. Storm sewer maintenance and inspection required per the table
below.
Storm Sewer Maintenance and Inspection
Inspection Pipes are difficult to inspect requiring special equipment and
training. Usually, if a problem occurs the owner needs to call a
sewer or plumbing contractor to inspect, repair or clean
pipelines.
Cleaning Clean pipes when sediment depth is greater than 10% of the
pipe diameter. When cleaning a pipe, minimize sediment and
debris discharges from pipes to the storm sewer. Install
downstream debris traps (where applicable) before cleaning and
then remove material. Generally, use mechanical methods to
remove root obstructions from inside storm sewer pipes. Do not
put root-dissolving chemicals in storm sewer pipes. If there is a
problem, remove the vegetation over the line.
Materials Handling Sediment and debris from pipes should be disposed in the
garbage as solid waste. Pick out any rocks first.
Repairs Repair or replace pipes when a dent or break closes more than
20 percent of the pipe diameter. Repair or replace pipes
damaged by deterioration.
Hydrodynamic Structure Maintenance and Inspection
An Aqua-SwirlTM concentrator is a swirl concentrator that removes pollutants from stormwater. These
pollutants include anything that is significantly heavier or lighter than water. Such pollutants include
sediment and oil from parking lots, Styrofoam cups and food packaging, cigarette butts, and other
debris. The AquaSwirlTM will also remove any heavy metals or nutrients (phosphorous and nitrates) that
will bond to the sediment and organic material that the AquaSwirlTM removes.
The Aqua-SwirlTM is a one-piece plastic, or Fiberglass Reinforced Plastic (FRP), structure that includes a
cast iron frame and cover. The cover of the AquaSwirlTM has the company logo on it to make it easy to
find for maintenance. The opening has a 30” diameter to provide easy access for maintenance from
grade level. There should never be a need for someone to enter the AquaSwirl TM. It is designed so that
inspection and maintenance can be easily conducted from grade level.
Because Aqua-SwirlTM’s collect pollutants, they need to be inspected and cleaned periodically.
The following Operation & Maintenance (O & M) procedures are the specific responsibilities for the
owner. Refer to the Tabular Maintenance Schedule included in Appendix D of this report for
maintenance requirements.
Underground Detention
Underground detention chambers are designed to detain the stormwater before being released through
outlet control structures. Equalizer pipes will be utilized to connect the underground detention systems,
which will need to be maintained in accordance with the storm sewer maintenance and inspection guide
located in Appendix C. These chambers need to be cleaned to remove sediment or blockages when
problems are identified. These units must be clear of obstructions and breaks to prevent localized
flooding. Storm sewer maintenance and inspection required per the table below.
Turf Vegetative Coverage
All non-paved areas that are not landscaped shall be vegetated to prevent erosion and sediment buildup
in storm sewer facilities onsite or downstream of the project site. Seed shall be reapplied as required to
establish healthy, dense coverage.
The following Operation & Maintenance (O & M) procedures are the specific responsibilities for the
owner. Refer to the Tabular Maintenance Schedule included in Attachment B of this report for
maintenance requirements.

Attachment C: R-Tank Operations and
Maintenance Manual
Operation
Your ACF R-Tank System has been designed to function in conjunction with the engineered drainage system on your
site, the existing municipal infrastructure, and/or the existing soils and geography of the receiving watershed. Unless
your site included certain unique and rare features, the operation of your R-Tank System will be driven by naturally
occurring systems and will function autonomously. However, upholding a proper schedule of Inspection & Maintenance
is critical to ensuring continued functionality and optimum performance of the system.
Inspection
Both the R-Tank and all stormwater pre-treatment features incorporated into your site must be inspected regularly.
Inspection frequency for your system must be determined based on the contributing drainage area, but should never
exceed one year between inspections (six months during the first year of operation).
Inspections may be required more frequently for pre-treatment systems. You should refer to the manufacturer
requirements for the proper inspection schedule.
With the right equipment your inspection and measurements can be accomplished from the surface without physically
entering any confined spaces. If your inspection does require confined space entry, you MUST follow all local/regional
requirements as well as OSHA standards.
R-Tank Systems may incorporate Inspection Ports, Maintenance Ports, and/or adjoining manholes. Each of these
features are easily accessed by removing the lid at the surface. With the cover removed, a visual inspection can be
performed to identify sediment deposits within the structure. Using a flashlight, ALL access points should be examined
to complete a thorough inspection.
Inspection Ports
Usually located centrally in the R-Tank System, these perforated columns are designed to give the user a base-line
sediment depth across the system floor.
Maintenance Ports
Usually located near the inlet and outlet connections, you’ll likely find deeper deposits of heavier sediments when
compared to the Inspection Ports.
Manholes
Most systems will include at least two manholes - one at the inlet and another at the outlet. There may be more than
one location where stormwater enters the system, which would result in additional manholes to inspect.
Bear in mind that these manholes often include a sump below the invert of the pipe connecting to the R-Tank.
These sumps are designed to capture sediment before it reaches the R-Tank, and they should be kept clean to
ensure they function properly. However, existence of sediment in the sump does NOT necessarily mean sediment
has accumulated in the R-Tank.
After inspecting the bottom of the structure, use a mirror on a pole (or some other device) to check for sediment
or debris in the pipe connecting to the R-Tank.

TECHNICAL
STORMWATER MANAGEMENT
For more information about our products, contact Inside Sales at 800.448.3636
or email at info@acfenv.com
If sediment or debris is observed in any of these structures, you should determine the depth of the
material. This is typically accomplished with a stadia rod, but you should determine the best way to
obtain the measurement.
All observations and measurements should be recorded on an Inspection Log kept on file. We’ve
included a form you can use at the end of this guideline.
Maintenance
The R-Tank System should be back-flushed once sediment accumulation has reached 6” or 15% of the
total system height. Use the chart below as a guideline to determine the point at which maintenance
is required on your system.
Before any maintenance is performed on your system, be sure to plug the outlet pipe to prevent
contamination of the adjacent systems.
To back-flush the R-Tank, water is pumped into the system through the Maintenance Ports as rapidly
as possible. Water should be pumped into ALL Maintenance Ports. The turbulent action of the water
moving through the R-Tank will suspend sediments which may then be pumped out.
If your system includes an Outlet Structure, this will be the ideal location to pump contaminated
water out of the system. However, removal of back-flush water may be accomplished through the
Maintenance Ports, as well.
For systems with large footprints that would require extensive volumes of water to properly flush
the system, you should consider performing your maintenance within 24 hours of a rain event.
Stormwater entering the system will aid in the suspension of sediments and reduce the volume of
water required to properly flush the system.
Once removed, sediment-laden water may be captured for disposal or pumped through a DirtbagTM
(if permitted by the locality).

PART 2 - PRODUCTS
2.01 R-TANK UNITS
A.R-Tank - Injection molded plastic tank plates assembled to form a 95% void modular structure of predesigned height (custom for each project).
B.R-Tank units shall meet the following Physical & Chemical Characteristics:
C.Supplier: Ferguson Waterworks 2831 Cardwell Road Richmond, VA 23234 (T): 800-448-3636; (F): 804-743-7779 www.ferguson.com
2.02 GEOSYNTHETICS
A.Geotextile. A geotextile envelope is required to prevent backfill material from entering the R-Tank modules.
1.Standard Application: The standard geotextile shall be an 8 oz per square yard nonwoven geotextile (ACF N080 or equivalent).
2.Infiltration Applications: When water must infiltrate/exfiltrate through the geotextile as a function of the system design, a woven monofilament (ACF M200 or equivalent) shall be used.
B.Geogrid. For installations subject to traffic loads and/or when required by project plans, install geogrid (ACF BX12 or equivalent) to reinforce backfill above the R-Tank system.
Geogrid is not always required for R-TankUD/ installations, and is often not required for non-traffic load applications.
2.03 BACKFILL & COVER MATERIALS
A.Bedding Materials: Stone (angular and smaller than 1.5” in diameter) or soil (GW, GP, SW, or SP as classified by the Unified Soil Classification System) shall be used below the
R-Tank system (3” minimum). Material must be free from lumps, debris, and any sharp objects that could cut the geotextile. Material shall be within 3 percent of the optimum moisture
content as determined by ASTM D698 at the time of installation. For infiltration applications bedding material shall be free draining.
B.Side and Top Backfill: Material must be free from lumps, debris and any sharp objects that could cut the geotextile. Material shall be within 3 percent of the optimum moisture content
as determined by ASTM D698 at the time of installation.
1.Traffic Applications - Free draining material shall be used adjacent to (24” minimum) and above (for the first 12”) the R-Tank system.
a.For HD, and SD modules, backfill materials shall be free draining stone (angular and smaller than 1.5” in diameter) or soil (GW, GP, SW, or SP as classified by the Unified Soil
Classification System).
b.For UD modules with less than 14” of top cover, backfill materials shall be free draining stone (angular and smaller than 1.5” in diameter). The use of soil backfill on the sides and top
of the UD module is not permitted unless the modules are installed outside of traffic areas or with cover depths of 14” or more. Top backfill material (from top of module to bottom of
pavement base or 12” maximum) must be consistent with side backfill.
2.Non-Traffic / Green Space Applications - For all R-Tank modules installed in green spaces and not subjected to vehicular loads, backfill materials may either follow the guidelines for
Traffic Applications above, or the top backfill layer (12” minimum) may consist of AASHTO #57 stone blended with 30-40% (by volume) topsoil to aid in establishing vegetation.
C.Additional Cover Materials: Structural Fill shall consist of granular materials meeting the gradational requirements of SM, SP, SW, GM, GP or GW as classified by the Unified Soil
Classification System. Structural fill shall have a maximum of 25 percent passing the No. 200 sieve, shall have a maximum clay content of 10 percent and a maximum Plasticity Index

dimensions in each direction allowing for installation of geotextile filter fabric, R-Tank modules, and free draining backfill materials.
B.All excavations must be prepared with OSHA approved excavated sides and sufficient working space.
C.Protect partially completed installation against damage from other construction traffic by establishing a perimeter with high visibility construction tape, fencing, barricades, or other
means until construction is complete.
D.Base of the excavation shall be uniform, level, and free of lumps or debris and soft or yielding subgrade areas. A minimum 2,000 pounds per square foot bearing capacity is required.
1.Standard Applications: Compact subgrade to a minimum of 95% of Standard Proctor (ASTM D698) density or as required by the Owner's engineer.
2.Infiltration Applications: Subgrade shall be prepared in accordance with the contract documents. Compaction of subgrade should not be performed in infiltration applications.
E.Unsuitable Soils or Conditions: All questions about the base of the excavation shall be directed to the owner's engineer, who will approve the subgrade conditions prior to placement
of stone. The owner's engineer shall determine the required bearing capacity of the R-Tank subgrade; however in no case shall a bearing capacity of less than 2,000 pounds per
square foot be provided.
1.If unsuitable soils are encountered at the subgrade, or if the subgrade is pumping or appears excessively soft, repair the area in accordance with contract documents and/or as
directed by the owner's engineer.
2.If indications of the water table are observed during excavation, the engineer shall be contacted to provide recommendations.
3.Do not start installation of the R-Tank system until unsatisfactory subgrade conditions are corrected and the subgrade conditions are accepted by the owner's engineer.
3.03 PREPARATION OF BASE
A.Place a thin layer (3” unless otherwise specified) of bedding material (Section 2.03 A), over the subgrade to establish a level working platform for the R-Tank modules. Level to within
½” (+/- ¼”) or as shown on the plans. Native subgrade soils or other materials may be used if determined to meet the requirements of 2.03 A and are accepted by the owner's
engineer.
1.Standard Applications: Static roll or otherwise compact bedding materials until they are firm and unyielding.
2.Infiltration Applications: Bedding materials shall be prepared in accordance with the contract documents.
B.Outline the footprint of the R-Tank system on the excavation floor using spray paint or chalk line to ensure a 2' perimeter is available around the R-Tank system for proper installation
and compaction of backfill.
3.04 INSTALLATION OF THE R-TANKS
A.Where a geotextile wrap is specified on the stone base, cut strips to length and install in excavation, removing wrinkles so material lays flat. Overlap geotextile a minimum 12” or as
recommended by manufacturer. Use tape, special adhesives, sandbags or other ballast to secure overlaps. As geotextiles can be damaged by extreme heat, smoking is not
permissible on/near the geotextile, and tools using a flame to tack the overlaps, such as propane torches, are prohibited.
B.Where an impervious liner (for containment) is specified, install the liner per manufacturer's recommendations and the contract documents. The R-Tank units shall be separated from
impervious liner by a non-woven geotextile fabric installed accordance with Section 3.04A.
C.Install R-Tank modules by placing side by side, in accordance with the design drawings. No lateral connections are required. It is advisable to use a string line to form square corners
and straight edges along the perimeter of the R-Tank system. The modules are to be oriented as per the design drawing with required depth as shown on plans.
1.For LD, HD, and SD installations, the large side plate of the tank should be placed on the perimeter of the system. This will typically require that the two ends of the tank area will
have a row of tanks placed perpendicular to all other tanks. If this is not shown in the construction drawings, it is a simple field adjustment that will have minimal effect on the overall
system footprint. Refer to R-Tank Installation Guide for more details
2.For UD installations, there is no perpendicular end row required.
D.Wrap the R-Tank top and sides in specified geotextile. Cut strips of geotextile so that it will cover the sides and top, encapsulating the entire system to prevent backfill entry into the
system. Overlap geotextile 12” or as recommended by manufacturer. Take great care to avoid damage to geotextile (and, if specified, impervious liner) during placement.
E.Identify locations of inlet, outlet and any other penetrations of the geotextile (and optional liner). These connections should be installed flush (butted up to the R-Tank) and the
geotextile fabric shall be cut to enable hydraulic continuity between the connections and the R-Tank units. These connections shall be secured using pipe boots with stainless steel
pipe clamps. Support pipe in trenches during backfill operations to prevent pipe from settling and damaging the geotextile, impervious liner (if specified) or pipe. Connecting pipes at
90 degree angles facilitates construction, unless otherwise specified. Ensure end of pipe is installed snug against R-Tank system.
F.Install Inspection and Maintenance Ports in locations noted on plans. At a minimum one maintenance port shall be installed within 10' of each inlet & outlet connection, and with a
maximum spacing of one maintenance port for every 2,500 square feet. Install all ports as noted in the R-Tank Installation Guide.
G.If required, install ventilation pipes and vents as specified on drawings to provide ventilation for proper hydraulic performance. The number of pipes and vents will depend on the size
of the system. Vents are often installed using a 90 degree elbow with PVC pipe into a landscaped area with 'U” bend or venting bollard to inhibit the ingress of debris. A ground level
concrete or steel cover can be used.
3.05 BACKFILLING OF THE R-TANK UNITS
A.Backfill and fill with recommended materials as follows:
1.Place freely draining backfill materials (Section 2.03 B) around the perimeter in lifts with a maximum thickness of 12”. Each lift shall be placed around the entire perimeter such that
each lift is no more than 24” higher than the side backfill along any other location on the perimeter of the R-Tank system. No fill shall be placed over top of tanks until the side backfill
has been completed.
2.Each lift shall be compacted at the specified moisture content to a minimum of 95% of the Standard Proctor Density until no further densification is observed (for self-compacting
stone materials). The side lifts must be compacted with walk behind compaction equipment. Even when “self-compacting” backfill materials are selected, a walk behind vibratory
compactor must be used.
3.Take care to ensure that the compaction process does not allow the machinery to come into contact with the modules due to the potential for damage to the geotextile and R-Tank
units.
4.No compaction equipment is permissible to operate directly on the R-Tank modules.
5.Top Backfill: Only low pressure track vehicles shall be operated over the R-Tank system during construction. Dump Trucks and Pans shall not be operated within the R-Tank system
footprint at any time. Heavy equipment should unload in an area adjacent to the R-Tank system and the material should be moved over the system using tracked equipment with an
operating weight of less than 10 tons.
a. Typical Applications: Install a 12” (or as shown on plans) lift of freely draining material (Section 2.03 B) over the R-Tank Units, maintaining 12” between equipment tracks and
R-Tank System. Lightly compacted using a walk-behind trench roller. Alternately, a roller (maximum gross vehicle weight of 6 tons) may be used. Roller must remain in static
mode until a minimum of 24” of cover has been placed over the modules. Sheep foot rollers should not be used.
b. Shallow Applications (< 18” total cover): Install top backfill in accordance with plans.
6.If required, install a geogrid as shown on plans. Geogrid shall extend a minimum of 3 feet beyond the limits of the excavation wall.
7.Following placement and compaction of the initial cover, subsequent lifts of structural fill (Section 2.03 C) shall be placed at the specified moisture content and compacted to a
minimum of 95% of the Standard Proctor Density and shall cover the entire footprint of the R-Tank system. During placement of fill above the system, unless otherwise specified, a
uniform elevation of fill shall be maintained to within 12” across the footprint of the R-Tank system. Do not exceed maximum cover depths listed in Table 2.01 B.
8. Place additional layers of geotextile and/or geogrid at elevations as specified in the design details. Each layer of geosynthetic reinforcement placed above the R-Tank system shall
extend a minimum of 3 feet beyond the limits of the excavation wall.
B.Ensure that all unrelated construction traffic is kept away from the limits of excavation until the project is complete and final surface materials are in place. No non-installation related
loading should be allowed over the R-Tank system until the final design section has been constructed (including pavement).
C.Place surfacing materials, such as groundcovers (no large trees), or paving materials over the structure with care to avoid displacement of cover fill and damage to surrounding
areas.
D.Backfill depth over R-Tank system must be within the limitations shown in the table in Section 2.01 B. If the total backfill depth does not comply with this table, contact engineer or
manufacturer's representative for assistance.
3.06 MAINTENANCE REQUIREMENTS
A.A routine maintenance effort is required to ensure proper performance of the R-Tank system. The Maintenance program should be focused on pretreatment systems. Ensuring these
structures are clean and functioning properly will reduce the risk of contamination of the R-Tank system and stormwater released from the site. Pre-treatment systems shall be
inspected yearly, or as directed by the regulatory agency and by the manufacturer (for proprietary systems). Maintain as needed using acceptable practices or following
manufacturer's guidelines (for proprietary systems).
B.All inlet pipes and Inspection and/or Maintenance Ports in the R-Tank system will need to be inspected for accumulation of sediments at least quarterly through the first year of
operation and at least yearly thereafter.
C.If sediment has accumulated to the level noted in the R-Tank Maintenance Guide or beyond a level acceptable to the Owner's engineer, the R-Tank system should be flushed.
D.All inspection and maintenance activities should be performed in accordance with the R-Tank Operation, Inspection & Maintenance Manual.

Maintenance Guidelines
The artificial grass designed specifically for dogs!
Welcome
Congratulations on your investment in K9Grass® by
ForeverLawn®. We are excited to have you as a part of the
ForeverLawn K9Grass family. As you know, K9Grass is the
artificial grass made specifically for dogs, and is the premier
surfacing product for dogs everywhere.
We want to make sure that your experience with K9Grass
is as enjoyable and successful as possible. Defining and
following specific maintenance guidelines for your unique
situation is important. To help you get there, this document
provides general maintenance guidelines with common
thresholds. Please contact your ForeverLawn dealer to find
out how best to tailor them for you.
Success with artificial grass in pet applications comes down
to three simple steps:
1. Choose the best product (which you have already found
in K9Grass by ForeverLawn).
2. Ensure that the product is correctly installed. This is best
achieved by our professional installation team.
3. Properly care for your K9Grass. Refer to the general
guidelines provided below, and tailor them to fit
your specific needs as determined by you and your
ForeverLawn dealer.
Proper K9Grass Maintenance
Remove large debris regularly and solid waste
immediately.
Debris such as leaves and sticks should be removed
regularly. Leaf rakes and blowers are great tools to
accomplish this.
Solid pet waste is easy to locate and should be removed
frequently (immediately if possible—the sooner the better).
The more dogs there are, the more important this is. If the
solid waste is messy, pick up all that you can, rinse with
a hose, and treat with a bacterial enzyme. DO NOT RINSE
SOLID WASTE INTO THE GRASS.
Use a bacterial enzyme cleaner (odor eliminator
with live bacteria).
It is advisable to have a spray bottle filled with
premixed bacterial enzyme to treat the spot where
the waste was removed. We recommend Got Pee
Odor Eliminator, which can be purchased through your
ForeverLawn dealer. The product is a concentrate so it
can be easily diluted for use in hand-held spray bottle.
Broad spraying of a bacterial enzyme should be done
regularly. A hose attachment is available for purchase
from your ForeverLawn dealer and is recommended.
Early evening is a good time to treat outdoor areas.
Indoor K9Grass typically requires an application of
once per day at a minimum. The purpose of these
treatments is to break down residual waste (urine and
feces) which, if not addressed, can be the source of
odor or unclean conditions. The longer the bacterial
enzyme is left on the grass, the better it works.
Got Pee Odor Eliminator, specially designed containing
live bacteria, is safe for use with dogs. If another
brand is used, we recommend that you consult with
the manufacturer to confirm that it is safe to use with
dogs. The product activates and continues to work
as long as there is moisture and pet waste present.
In lieu of a hose applicator, rinse well with a hose and
mist grass with a premixed spray (6 - 8 ounces per
gallon applied with a pump sprayer).
Frequency of treatment will be dependent on the size
of the area, number of dogs, climate, use, and design
of installation.Consult your ForeverLawn dealer for
specific guidelines. General guidelines are to apply
bacterial enzymes on a regular interval preemptively
heading off odors (you will need to find the frequency
that works for you). Reactively, it can be applied
any time there is an odor. A good place to begin for
common outdoor use is to start weekly then increase
or decrease based on results.
Additional Notes
• Rinsing the grass between cleanings is advisable if you
do not have regular rain.
• If you have a sick dog, clean and sanitize the area
by removing the bulk matter, apply Got Pee Odor
Eliminator bacterial product to that area. Allow the
bacterial action to consume and liquify blood, urine,
feces, and vomit. Then rinse or extract the area clean
with water to flush away contaminants. Got Pee Odor
Eliminator cleans and deodorizes K9Grass with every
application.
• If you have a flushing system, it is designed to
dilute urine and move it to the drain. Consult your
ForeverLawn dealer regarding frequency and duration.

family! Please do not hesitate to call your ForeverLawn
K9Grass dealer with maintenance questions or concerns.
We are glad to assist you.
Remove small debris with vacuums and extraction
equipment.
It is important to remove hair and smaller debris to keep
the K9Grass performing at its best. This can be
accomplished by running a vacuum when the grass is
dry (with a rotating brush and strong suction) to groom,
agitate, and remove debris. For installations under 1,500
square feet, a household vacuum can be used. Larger
areas may require a commercial vacuum or a power broom
(consult your ForeverLawn dealer). Frequency is dependent
on size, number of dogs, and how the area is used.
Removing this debris keeps the grass looking good and
prevents urine, hair, and waste from slowing drainage and
holding unwanted waste.
Outdoor area: A common place to start for an area
of typical size and use is to vacuum hair and small
debris once a month. Remember, this is a starting
point and will likely need to be adjusted by monitoring
the amount of debris and hair coming out. High-use
outdoor areas may require weekly vacuuming. A shop
vac can be used around the perimeter (fence and
walls).
Indoor area: A common place to start for an indoor
area of typical size and use is to begin by extracting
and vacuuming every other day. A commercial-grade
carpet extractor may be preferred for indoor use as
it can be run when the grass is wet, pulling out hair
and debris while also removing residual water. This is
a starting point and will likely need to be adjusted by
monitoring the amount of debris and hair coming out.
It is very common for daily vacuuming and extraction
to be required for indoor areas. A shop vac can be
used around the perimeter (fence and walls).
