Pittsburgh Water is the largest combined water and sewer authority in Pennsylvania. It provides water, sewer, and stormwater management services to more than 300,000 customers throughout the City of Pittsburgh and the surrounding areas.

Water

The drinking water system contains approximately 965 miles of water lines, 1 raw water pump station, 10 finished water pump stations, 3 reservoirs, and 13 tanks. The PWSA provides water to the Borough of Millvale and approximately 84% of the total population in the geographic boundary of the City of Pittsburgh. In addition, Pittsbrugh Water provides bulk water services to Reserve Township, Fox Chapel Borough, and the Borough of Aspinwall, along with being interconnected to several other regional water systems for emergency purposes.

The water distribution system is a vast, complex network that was designed to take advantage of Pittsburgh unique geography. Gravity, along with the help of pump stations, reservoirs, and tanks, moves water throughout Pittsburgh’s hills and valleys.

Sewer

The sewer system includes 1,200 miles of sewer lines and approximately 25,000 catch basin and inlets. Approximately 75% of the sewer system is a combined system meaning that stormwater and wastewater flow through the same pipe. The remaining 25% is a separated system, which means that wastewater flows through one pipe and stormwater flows through another. The PWSA sends all wastewater to the Allegheny County Sanitary Authority (“ALCOSAN”) wastewater treatment plant, which is not part of the PWSA’s system. ALCOSAN treats wastewater for the 83 municipalities in Allegheny County, including the City of Pittsburgh.

Stormwater

As heavier and more intense rains are overwhelming Pittsburgh Water’s sewer system, stormwater management is a growing concern throughout Pittsburgh. To solve the problem, Pittsburgh Water is taking a more deliberate approach about the way it is managed across the region.

Rather than directing all that extra water into a network of pipes, we are distributing the collection of rainwater into a series of stormwater infrastructure projects across the city. This distributed approach will help to capture, absorb, hold back, and slow the flow of stormwater.

These methods use a combination of green and gray infrastructure and integrate into the natural environment. It is a cost-effective approach that will help to create safe, flood-prepared neighborhoods.
