I. INTRODUCTION
The proposed Project is located at 12 St Raymond Ct, in the City of Saratoga Springs, Saratoga
County, NY. The project includes water and sanitary sewer connections to two new single-family
residences.
II. EXISTING WATER AND SANITARY UTILITES
City water service is currently available adjacent to the site. A 4” water main is located along the
east side of St Raymond Court, west of the site, with a fire hydrant located on the northwest
corner of the parcel.
City sanitary sewer service is available along Grand Avenue. The 8” municipal sanitary main is
located approximately 170’ west of the St. Raymond Court intersection. Wastewater from this
system ultimately flows to the Saratoga County Sewer District No. 1 (SCSD) wastewater
treatment plant in Mechanicville.
III. PROJECTED WATER AND WASTEWATER FLOWS
Table 1 below provides information on the anticipated average potable water use and wastewater
flow rates for the Project in gallons per day (gpd). Water use and wastewater flow are estimated
to be equal for this study.
Table 1
Description Use Rate Total Use
(2) 3-Bedrooms 110 gpd/each1 660 gpd
Total 660 gpd
Average daily flow for wastewater is estimated to be 0.46 gallons per minute (gpm). Estimated
peak hourly flow is 1.93gpm (4.2 x average)2.
Average daily demand for water is estimated to be approximately equal to the wastewater flow
or 0.46 gpm.
IV. PROPOSED WATER AND WASTEWATER UTILITIES
A. Proposed Potable Water Utilities
To service each residence, a 3/4” Type K copper water service is proposed to connect from
the east of each residence to the 4” water main on the east side of St Raymond Court.
Connection and appurtenances including corporation stops, trenching, bedding, service
connections, as well as testing and disinfection will all be specified in accordance with the
City of Saratoga Springs and NYSDOH standards.
B. Proposed Wastewater Utilities
For sanitary sewer collection, a sanitary main extension is proposed to extend the municipal
line to service St Raymond Ct. Extension of the sanitary line will be completed by the City of
Saratoga. 6” SDR-26 sanitary laterals will be provided to the two lots from the extended
municipal line.
