Your body needs water to function properly. Most people can stay hydrated by drinking water whenever they feel thirsty. However, when summer heat waves strike or a hard workout makes you sweat, remember to drink extra water to make up for fluid loss.   

For your hydration needs, you can have confidence in tap water from the Pittsburgh Water and Sewer Authority. Our 2020 Annual Drinking Water Quality Report shows a clean bill of health for the quality and safety of our drinking water. This annual report outlines our treatment process, the effectiveness of our water quality testing, and the sample results of the various contaminants found in our source water – the Allegheny River. 

• More than 100,000 analyses conducted: Each day, we tested for approximately 100 different chemical and microbial contaminants before, during, and after the treatment process.
• No test results exceeded federal or state maximum contaminant levels (MCLs): Our treatment process maximizes the reduction and removal of contaminants from your drinking water.
• Lowest lead levels in 20 years: After implementation of an improved corrosion control treatment called orthophosphate, our lead levels came into compliance with federal regulatory standards.
• Improved secondary treatment of reservoir water: The Highland Park Microfiltration Plant, which provides a second layer of treatment to water leaving the open Highland I Reservoir, was fully restored to meet stricter water quality standards.
• Decreased turbidity levels a testament to our treatment process: We are effectively filtering out the suspended solids found in our source water, producing clearer water or lower turbidity.
