PROJECT DESCRIPTION
The project is located at 30 Washington Street in the City of Saratoga Springs, New York. It
involves relocating the existing stone building from the Adelphi site to this location, where it will
be installed west of the Bethesda Church. The relocated building will serve as office and
gathering space for the church.
EXISTING CONDITIONS
Water Distribution – A 10” City of Saratoga Springs watermain is located on the south side of
Washington Street along the frontage of the subject parcel.
Sanitary Sewer – A 12” vitrified clay sanitary main runs along the center of Washington 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.
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)
Office: (10 employees) x (15 gpd/employee)1 150 gpd
Total 150 gpd
Summary of Design Flows
Peak flow is estimated to be 4.8 gallons per minute (gpm) per Table 604.3 of the 2025 NYS
Plumbing Code based on all building fixtures simultaneously being used.
PROPOSED CONDITIONS
Water Distribution – To serve the project a new ¾” copper water service will be provided off the
10” municipal water main in Washington Street. The building will not be sprinklered and will
require domestic water service only. The nearest fire hydrant is located at the northwest corner
of the church building on the site.
Sanitary Sewer – A new 6” SDR-26 sewer lateral will provide sanitary sewer service for the
building. The new lateral will connect to the existing 12” City sanitary main in Washington
Street.
