Facts & Figures

  • MAWC serves over 120,000 drinking water customers in a five-county region, and approximately 25,000 wastewater customers
  • MAWC has three drinking water treatment plants which can produce over 70 million gallons of water per day. All three have undergone recent updates.
  • MAWC has 2,400 miles of water transmission lines; 8,300 hydrants; 67 water storage tanks with a capacity of 107 million gallons; 48 pumping stations and 95 pressure regulators.
  • MAWC water mains laid end to end from Greensburg would stretch west nearly to southernmost Alaska, or south to Colombia.

From AWWA’s report, Buried No Longer, Confronting America’s Water Infrastructure Challenge:

“As documented in this report, restoring existing water systems as they reach the end of their useful lives and expanding them to serve a growing population will cost at least $1 trillion over the next 25 years, if we are to maintain current levels of water service. Delaying the investment can result in degrading water service, increasing water service disruptions, and increasing expenditures for emergency repairs. Ultimately we will have to face the need to ‘catch up’ with past deferred investments, and the more we delay the harder the job will be when the day of reckoning comes.

“Overlooking or postponing infrastructure renewal investments in the near term will only add to the scale of the challenge we face in the years to come. Postponing the investment steepens the slope of the investment curve that must ultimately be met. It also increases the odds of facing the high costs associated with water main breaks and other infrastructure failures.”

From the American Society of Civil Engineers 2017 Infrastructure Report Card:

“Drinking water is delivered via one million miles of pipes across the country. Many of those pipes were laid in the early to mid-20th century with a lifespan of 75 to 100 years. The quality of drinking water in the United States remains high, but legacy and emerging contaminants continue to require close attention. While water consumption is down, there are still an estimated 240,000 water main breaks per year in the United States, wasting over two trillion gallons of treated drinking water. According to the American Water Works Association, an estimated $1 trillion is necessary to maintain and expand service to meet demands over the next 25 years.”

“The nation’s 14,748 wastewater treatment plants are the most basic and critical infrastructure systems for protecting public health and the environment. Years of treatment plant upgrades and more stringent federal and state regulations have significantly reduced untreated releases and improved water quality nationwide. It’s expected that more than 56 million new users will be connected to centralized treatment systems over the next two decades, requiring at least $271 billion to meet current and future demands. New methods and technologies turn waste into energy relying on the nation’s 1,269 biogas plants to help communities to better manage waste streams through reuse.”

From the Pennsylvania section of the report:

“Drinking water infrastructure in Pennsylvania faces a required investment of $13.9 billion over the next 20 years to replace aging facilities and comply with safe drinking water regulations. Although waterborne outbreaks are low, the number of incidents has been on the rise. It is encouraging that the number of drinking water systems in violation of clean water regulations has declined. Drinking water facilities will require a steady source of funding. Drinking water systems must adopt full-cost pricing in water billing to reflect operational and maintenance costs, as well as raising funds for eventual replacement. If funding needs are not met, the state risks reversing the public health, environmental, and economic gains that have been made over the past three decades.”

“The Commonwealth must invest $28 billion over the next 20 years to repair existing systems, meet clean water standards, and build or expand existing systems to meet increasing demands. The Pennsylvania Infrastructure Investment Authority’s (PENNVEST) budget in 2013 for grant and loan awards for sewer projects is $335 million, less than 25 percent of the required annual investment. In 2013, Pennsylvania’s appropriation from the Federal Clean Water Act also decreased to $53 million.”
