The Parsons Avenue Water Plant (PAWP) is a critical component in the City’s potable water supply system. The PAWP currently has 6 collector wells. This project provides engineering design and construction improvements for the 7th radial collector well as an additional raw water source for the PAWP. This project is part of the City’s ongoing program to upgrade its treatment facilities to provide safe, efficient, reliable, cost-effective operations for its approximately 1.2 million customers.
