Piedad Water Treatment Plant Categorical Exclusion Determination

The Alaska Department of Environmental Conservation's State Revolving Fund Program has determined that the Piedad Water Treatment Plant project is eligible for a Categorical Exclusion. The project will upgrade the Piedad Pressure Sustaining Valve, construct a small utility building, and add a chlorine room to increase the lifespan of monitoring equipment. A DWSRF loan in the amount of $1,300,000 has been requested for this project. The key aspects of this project include: • Upgrading the Piedad Pressure Sustaining Valve to a 4-inch diameter • Constructing a small utility building over the vault • Adding a chlorine room to isolate chlorine from other WTP equipment • Increasing chlorine contact time, fire suppression, and water supply volume This project is expected to improve the quality of the drinking water and increase the efficiency of the treatment plant.
