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, over 32,000 valves and hydrants, 1 raw water pump station, 10 finished water pump stations, 4 finished water reservoirs, 1 source water reservoir reservoirs, and 11 tanks. Pittsburgh Water 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 1,242 miles of sewer lines and approximately 25,000 catch basin and inlets. Approximately 73% of the sewer system is a combined system meaning that stormwater and wastewater flow through the same pipe. The remaining 27% is a separated system, which means that wastewater flows through one pipe and stormwater flows through another. Pittsburgh Water sends all wastewater to the Allegheny County Sanitary Authority (“ALCOSAN”) wastewater treatment plant, which is not part of the Pittsburgh Water 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. Pittsburgh Water currently maintains 3 sanitary sewer overflow structures, 146 combined sewer overflow outfall structures, 46 combined sewer overflow outfall structure co-permitted with ALCOSAN, and 254 separate storm sewer outfalls in the Municipal Separate Storm Sewer System.

News
Pittsburgh, PA - Pittsburgh Water has received Positive outlooks on its credit ratings from both Moody’s Ratings and S&P Global Ratings, reflecting strong financial management and continued confidence in the utility’s ability to fund critical infrastructure investments.
The agencies affirmed Pittsburgh Water’s strong underlying credit ratings – A2 from Moody’s and A+ from S&P – and cited steady financial performance, improving regulatory relationships, and disciplined execution of capital projects as key drivers behind the outlook upgrades.
“The recent outlook upgrades from both Moody’s and S&P are further validation that our leadership team and Board of Directors are managing public finances responsibly,” said Pittsburgh Water CEO Will Pickering. “By continuing to manage our investments effectively, we will strengthen our vital public infrastructure and ensure reliable service for generations to come,” he continued.
The ratings were announced as Pittsburgh Water prepares to issue approximately $125.6 million in new bonds to support its capital improvement program.
What the rating agencies highlighted
According to S&P Global Ratings, the positive outlook reflects expectations that Pittsburgh Water will:
- Continue successfully delivering major capital projects
- Maintain strong financial metrics during an intensive investment period
- Strengthen its working relationship with the Pennsylvania Public Utility Commission
S&P also noted that there is a one-in-three chance of a future credit rating upgrade over the next two years if current performance trends continue.
Moody’s Ratings cited:
- Consistent financial results supported by strong management
- Solid debt service coverage and liquidity levels
- A clear commitment to making the investments needed to modernize aging infrastructure
Moody’s stated that a future upgrade could occur if coverage and cash reserves remain stable while Pittsburgh Water moves through the most capital-intensive phase of its improvement plan.
Long-term financial progress
Since 2018, Pittsburgh Water has steadily strengthened its credit profile:
- Moody’s: One credit rating upgrade and three outlook upgrades, now A2 with Positive outlook
- S&P Global Ratings: One credit rating upgrade and one outlook upgrade, now A+ with Positive outlook
“These positive outlooks reflect years of deliberate financial planning and operational improvements,” said Edward Barca, Pittsburgh Water’s Director of Finance. “They reinforce our ability to invest in critical infrastructure while maintaining financial stability and affordability for our customers.”
Pittsburgh Water’s capital improvement program exceeds $1 billion and focuses on replacing aging infrastructure, improving system reliability, and meeting regulatory requirements that protect public health and the environment.

Pittsburgh, PA - Pittsburgh Water announced today that it has received $31,510,340 in funding from the Pennsylvania Infrastructure Investment Authority (PENNVEST), consisting of a $15,903,876 grant and a $15,606,464 low-interest loan, to support its ongoing lead service line replacement program. This funding is in addition to the $795,744,703 in loans and $115,969,811 in grant funding the utility has previously secured from PENNVEST for systemwide improvements.
“Pittsburgh Water’s Lead Service Line Replacement program is a critically important investment in our neighborhoods, and we are thankful for PENNVEST’s record-setting funding,” said Mayor Corey O’Connor. "Not only has Pittsburgh Water already replaced nearly 25,000 public and private lead lines in 68 of the 73 neighborhoods where they provide drinking water, but the program has also supported hundreds of local union jobs and delivered equitable access to drinking water for all families.”
The new funding will enable Pittsburgh Water to replace approximately 1,610 lead service lines – 770 public and 840 private – in the neighborhoods of Bloomfield, Shadyside, Highland Park, and Central Lawrenceville. These projects are part of the utility’s comprehensive effort to remove all lead service lines in its service area by 2027, protecting public health and improving drinking water quality.
“Replacing lead service lines is one of the most important investments we can make to improve public health and drinking water quality,” Pittsburgh Water CEO Will Pickering said. “This funding ensures that residents in Bloomfield, Shadyside, Highland Park and Central Lawrenceville will have continued access to clean, safe drinking water, and it moves us closer to our goal of fully removing lead from our system.”
The project will support local jobs and economic activity as contractors work in the neighborhoods, contributing to both immediate employment and long-term community benefits. Residents can expect temporary service interruptions during construction, and Pittsburgh Water will provide advance notice to affected households. As part of this work, Pittsburgh Water will restore impacted sidewalks and repave roadways following construction, ensuring neighborhoods are returned to safe and usable conditions.
Since 2016, Pittsburgh Water has removed more than 14,000 public lead service lines and 10,600 private ones at no direct cost to ratepayers. The utility remains on track to remove all residential lead service lines by late 2027 and is entering the final locations where service line verification and removal of lead pipes is needed. The utility’s Community Lead Response follows an equity-based approach prioritizing neighborhoods with a concentration of young children and women of childbearing age, County health data, income, and density of lead lines in a neighborhood. This model, developed in consultation with the Community Lead Response Advisory Committee, ensured that the most at-risk neighborhoods are prioritized first.
Pittsburgh Water was also awarded two Pennsylvania Small Water & Sewer grants, totaling $850,000 for projects in Allegheny County. A $425,000 grant will support Pittsburgh Water’s Residential Meter Project, helping offset the cost of replacing customer water meters as part of the utility’s required meter replacement cycle and reducing costs for ratepayers. An additional $425,000 grant will fund leak reduction efforts through the purchase of advanced leak detection sensors. These investments will help reduce water loss, improve system efficiency, and advance Pittsburgh Water’s goal of minimizing treated water waste.
This funding marks another step forward in Pittsburgh Water’s multi-year strategy to modernize its water infrastructure while keeping customer costs low. By leveraging funding, Pittsburgh Water is able to maximize grant support and reduce the burden on ratepayers, while maintaining progress toward systemwide improvements.

Pittsburgh, PA - Pittsburgh Water has reached a major milestone in its nationally-recognized Community Lead Response, officially replacing its 14,000th lead service line since the initiative began in 2016. Pittsburgh is now regarded as one of the nation’s leading cities in proactively removing lead service lines, moving faster than many large water systems in the country. This ongoing work comes at no direct cost to customers, reflecting the utility’s commitment to protecting public health and delivering equitable water service across each community it serves.
There is no safe level of lead in drinking water. That’s why Pittsburgh Water is committed to replacing all residential lead lines in its system— both publicly and privately owned — to ensure cleaner, safer water for current and future generations of customers. While this work continues, customers can be confident that their drinking water meets the highest standards of safety and quality. Due to the utility’s highly effective water treatment process that includes the food-grade corrosion control additive orthophosphate, Pittsburgh Water recently recorded the lowest lead levels in its history: just 2 parts per billion (ppb), substantially lower than the 15 ppb regulatory limit
“We’ve achieved some truly remarkable successes in 2025, from getting lead levels down to a historically-low 2 ppb, to reaching yet another milestone in lead service line replacements,” said Pittsburgh Water CEO Will Pickering. “None of this would be possible without our deeply dedicated team and local partners. It’s that dedication that’s keeping us on pace to replace every residential lead line in our system before the end of 2027, placing us years ahead of most comparable water utilities across the country.”
To help finance this undertaking, Pittsburgh Water has strategically relied on alternative funding sources, primarily in the form of state and federal funding administered by the Pennsylvania Infrastructure Investment Authority (PENNVEST). Since 2018, PENNVEST has awarded Pittsburgh Water $795,774,703 in low-interest loans and $115,969,811 in grants for a total of $911,744,514, with their most recent award of nearly $78 million announced in October 2025. These funding infusions help Pittsburgh Water live up to its commitments to protect public health while providing equitable access to high-quality, affordable water services.
“PENNVEST’s grants and low-interest loans have played a critical role in supporting our Community Lead Response,” said Pickering. “This is a costly undertaking, and part of our commitment to equity and affordability is making sure our customers don’t bear all of the financial burden of these essential projects. Because of PENNVEST’s continued support and investment in Pittsburgh’s water future, we’re able to maintain an aggressive pace while keeping ratepayer costs as low as possible.”
