Highland Park System Improvement Projects
Several projects will take place in Highland Park. These are the first of many critical infrastructure projects, currently in their design phase, that are needed to modernize our water system. PWSA is beginning a community engagement process to inform the community about the projects and provide opportunities to share ideas and ask questions. Construction of these projects will begin as early as summer 2018 and will continue through 2021. 
 
Completing these projects is critical to starting work on other priority projects needed to modernize the water system. These include projects at the Aspinwall Water Treatment Plant, a series of Clearwell rehabilitation projects, and others that will add redundancy and efficiencies throughout the water system. 
 

Community Outreach

Join the conversation about the Highland Park System Improvement Projects. Highland Park is a beloved resource enjoyed by residents and visitors. It is home to the historic Highland Park Reservoir I, hiking trails, a pool, picnic pavilions, and is a place where friends and families gather throughout the year. While these projects will improve the distribution and treatment of water throughout Pittsburgh, they also offer opportunities to collaborate with the community and other agencies to identify possible improvements that will enhance the park and other local services. 
 
The first community meeting about the Highland Park System Improvement Projects will take place on Thursday, June 21 at St. Andrews Church in Highland Park. The meeting begins at 7:00 p.m. PWSA would like to thank the Highland Park Community Council for hosting this meeting and providing the space to share this important information. Residents throughout Pittsburgh and nearby communities are encouraged to attend. 
 

Highland Park System Improvement Projects 

Orthophosphate Facilities

We will construct two small buildings to store and distribute orthophosphate to the water system. Orthophosphate is used to reduce corrosion in existing lead pipes and will prevent lead from entering the water system. The buildings will meet design standards to fit the character of Highland Park and will be constructed near the vicinity of the Microfiltration Plant along Reservoir Drive. 
 

UV Treatment at Microfiltration Plant

The Microfiltration Plant, built in the 1990’s to keep Highland Park Reservoir I an open reservoir, was taken offline because it no longer met water quality standards as determined by the PA Department of Environmental Protection (DEP). To meet current water quality standards an extra layer of treatment must be added. UV (ultraviolet) Treatment will meet most of DEP’s new water quality standards. 
 

Securing Highland Park Reservoir I

To ensure the protection of the Highland Park Reservoir I, DEP is also requiring PWSA to enhance the security of the open reservoir. These security measures and the application of UV Treatment will enable PWSA to put the reservoir and the Microfiltration Plant back into service. 
 

Highland Park Rising Main and Pump Station 

The new rising main and reconstruction of the Negley Avenue Pump Station will modernize the distribution of water to the Garfield Tank which generally serves the neighborhoods of Garfield, Stanton Heights and parts of Central Lawrenceville. The existing pump was taken out of service and a temporary pump is currently supplying the Garfield Tank. A new pump station will supply its service area and will have the capacity to distribute 50 million gallons of water per day (mgd) to PWSA customers in this area. 
 
The new rising main will provide the system of pipes needed to connect the new pump station to the Highland I Reservoir. The rising main will be constructed in the general area of Mellon Terrace, Bunkerhill Street, and Highland Avenue. This location was chosen to minimize the impact to existing trees. 
 
While these projects are under construction, PWSA will also replace the existing cover on Highland Park Reservoir II and replace the pipe (an affluent main) that distributes water from this reservoir to the pump station. 
 
PWSA is coordinating these projects with the City of Pittsburgh, PAT Transit, the Pittsburgh Parks Conservancy, and the Pittsburgh Zoo to identify potential opportunities to enhance services and amenities around Highland Park. 
 
These projects will enhance the distribution of water, modernize existing infrastructure and equipment, which in some cases is a century old, and will add redundancy to our water system.
