RFP-2010-100 - Engineering Services Patroon Creek Intercepting Trunk Sewer Repair

Summary of Specifications:
The Albany County Sewer District owns and operates a treatment plant designated the North Plant, 1 Canal Road South, Menands, NY 12204. One of the main transmission conduits for the North Plant is the Patroon Creek intercepting trunk sewer which transmits flows west to east. The trunk sewer starts near I-87 (Northway) and runs generally parallel to I-90 to North Albany then jogs north to the North WWTP. In 2008 an investigation of this line noted an area of corrosion near the Pinebush Metering Station # 16. This metering station is a junction structure where wastewater is received from the City of Albany and the Town of Guilderland. Upon further investigation, the Patroon Creek trunk sewer downstream from this metering chamber also showed deterioration. The metering pit / junction box is reinforced concrete with the Patroon Creek Trunk sewer being reinforced concrete pipe (RCP). The issues were spalling of the concrete surfaces to the depth of the reinforcement.
