PROJECT DESCRIPTION
The project is located at 29 Myrtle Street in the City of Saratoga Springs, New York. It involves
the subdivision of two residential parcels into four residential parcels. The existing parcels are
zoned UR-2 Urban Residential. The existing house on proposed lot 3 is to remain.
EXISTING CONDITIONS
Water Distribution – A 4” City of Saratoga Springs watermain is located within Myrtle Street. The
existing house on proposed lot 3 is serviced off the 4” watermain. An existing curb stop is located
at the sidewalk in front of the existing house that is to remain.
Sanitary Sewer – An 8” sanitary main runs along the east side of Myrtle Street. This sanitary
main flows via gravity to the Saratoga County Sewer District Pump Station at High Rock
Avenue and Warren Street. From the pump station the wastewater is pumped to County trunk
lines and the treatment plant in Mechanicville. The existing house on proposed lot 3 discharges
to the 8” sewer main.
SEWER AND WATER USAGE
The table below provides information on the anticipated average potable water use and
wastewater flow rates for the project. Water use and wastewater flow are estimated to be equal
for this study.
Table - Average Daily Flow (ADF)
3 Bedroom Home: (4 homes) x (330 gpd/home)1 1,320 gpd
Total 1,320 gpd
Summary of Design Flows
Average daily flow for wastewater is estimated to be 0.9 gallons per minute (gpm) based on a 24
hour day. Estimated peak hourly flow is 3.9 gpm (4.38 x average).2
Average daily demand for water is estimated to be approximately equal to the wastewater flow
or 0.9 gpm. Instantaneous peak demand is estimated at 3.0 gpm3 for each residence giving a total
instantaneous demand of 12.0 gpm.
PROPOSED CONDITIONS
Water Distribution – To serve the project, three (3) new 3/4” copper water services will be
installed at the existing 4” water main. The water service to the existing house is to remain. The
nearest fire hydrant is located on the west side of Myrtle Street, at the southern property line of
the project.
Sanitary Sewer – To service the project, three (3) new sanitary sewer services will be installed at
the existing 8” sewer main. The sanitary sewer service to the existing house is to remain.
