sewer.
5. All sanitary sewer lines upon completion will be required to pass a low
pressure air test, unless otherwise directed by the City Engineer. Said test
shall be conducted according to NCPI Standard Method, and shall be witnessed
by the City Inspector. infiltration under test shall not exceed 200 gallons
per inch of inside diameter of sewer pipe per mile of sewer in 24 hours and

carried approximately to the property line, and the location of their
termination indicated on the surface with a suitable marker. The wye is to
be tilted up at 45 degrees from the horizontal and the end plugged tight

horizontal and vertical separation as stipulated above, the sewer shall be
designed and constructed equal to water pipe and shalt be pressure tested to
assure watertightness prior to backfilling.

otherwise noted in the plans or PVC of a type approved for water main
construction in lndidno.
A. Water lines shall be of de.ctile iron pipe, Class 50 cernert

A. Swale seeding Seed and fertilize within construction limits with 5#/ocre
"Redtop" grass. 20#/ocre "Rye Gross", 20#/acre "Blue Grass", 25#/ocre
"Tall Fescue" grass, and 600#/ocre 12-12-12 fertilizer.
B. Cut/Fill Seeding Along Paved Areas: Seed and fertilize with 25#/acre "Tall
Fescue" gross, 20#/ocre "Rye Gross", 15#/ocre "Blue Gross" and 600#/acre

outside grade. The finished floor elevation is 8 inches higher, more or less
thon the outside grade
