Report on Water Distribution, Sanitary Sewer and Storm Sewer SYsN;h1e2
1. Water Distribution
The potable water to the site will be provided by the Indianapolis Water Company (IWC).
Connections onto the existing mains will be made at the following location:
. A 16" main will be extended from it's current location at the intersection of Ditch Road
and 131 st Street. The new 16" main will run along our site's frontage on 131 st Street, and
will be stubbed at our Westernmost boundary for future extension by others.
. A second 16" main will be tapped and extended from the West, from it's terminus within
the Laurel Lakes Subdivision on 126th Street.
. A 12" main will be tapped and extended the Irsay Horse Arena on 136th Street.
. Another 12" main will be tapped within the existing Claridge Farm Subdivision, and a
12" main will be extended through our site.
. An 8" main will be tapped at the Laurel Lakes Subdivision entrance on Towne Road.
Preliminary hydraulic computations have been completed by IWC, and working in conjunction
with our estimated development of each section within the Village of West Clay, we have
developed a plan that ensures adequate pressure for fire fighting capabilities at all times during
the build out and beyond.
Approval for the extension of every water main will be required from the Indiana Department of
Environmental Management, and all mains will be designed and installed in accordance with
IWC rules and regulation.
2. Sanitary Sewer
Sanitary sewer effluent for the site will be accepted by the Clay Township Regional Waste
District (CTRWD). A lift sation is proposed along the Eastern boundary of the site which will
pump effluent via a force main into the existing 18" interceptor located in Springmill Road.
Two additional lift stations are proposed within the Village of West Clay to serve areas which
cannot be served by gravity sewers. One will be placed within the common area located along
Hoover Road, South of the Claridge Farm entrance. It will serve the Southern third of the
project, and will pump North into the gravity system described above. The station is temporary
in nature, and will be taken off line upon extension of the interceptor proposed to the South and
East shown in the CTR WD' s master plan.

The second station is also temporary, and is located along the project's Westernmost boundary
near 126th Street. The station will also pump to the gravity sewers to the East, and it serves the
portion of the project located West of Towne Road.
Approvals for the design and construction of the sanitary sewers must also be obtained, in
addition to the cTRWD and it's consultant, from the Indiana Department of Environmental
Management.
3. Storm Sewer
The surface runoff on the site will be conveyed by a system of swales and pipes to a network of
retention lakes within the Village of W estClay. In accordance with the requirements of the
Hamilton County Surveyor's requirements, the retention lakes will provide storm water
management control in order to restrict the discharge rates onto the site's various outfall points.
The discharge points for the site are as follows:
. Elliot Creek; which traverses the site along the Northern third, then crosses 131 st Street
and leaves the site just East of the existing 8.5 acre lake on the Perez parcel.
. Claridge Farms Legal Drain; which was sized per the County Surveyor's calculations, to
accept a 146 acre drainage area that lies within the boundary of the Village of W estClay.
Connection onto the Claridge Farm drain will be made at an existing 36" concrete pipe
just South of the existing mound bordering the Perez property, and will address drainage
problems evident at that location.
. Clay Creek; Which traverses the site along the Southern third, then crosses Hoover Road
near the proposed common area South of Claridge Farm entrance.
. Brendle Legal Drain; which flows along the site's Western boundary, then crossed 126th
Street West of Towne Road.
It is the intent that all main storm sewer lines and all lines interconnecting lakes and serving as
outlet points be petitioned to be accepted by the County Surveyor as regulated drains. A limited
portion of the storm sewers that serve to drain rear and side yards may remain within the
maintenance jurisdiction of the project's homeowner's association; however, most storm sewers
and all retention lakes will be maintained by the County Surveyor. Subsurface drains, or
pavement base drains, are proposed to be installed under the street curbs, in order to provide an
outlet point to home sump pumps, and in order to intercept groundwater seepage before reaching
and compromising the pavement stability.
4. Erosion Control
During all phases of the construction the Site General Contractor and all Subcontractors shall
exercise measures to prevent the erosion of soils due to the action of water and wind. All erosion
and sediment control measures shall be implemented prior to earth moving activities.
The proposed detention area along with any swales shall be constructed first. The detention area
