Pittsburgh, PA – The Pittsburgh Water and Sewer Authority (PWSA) will complete its final phase of the expedited sewer repair on Ivyglen and Odette streets in the Overbrook neighborhood with the lining of a storm sewer near Odette Street. This $1,090,000 project was completed under budget and restored regular sanitary sewer service for nearby residents.
In summer of 2018, a landslide near Saw Mill Run Boulevard destroyed a sewer main which served customers on Ivyglen and Odette Streets in Overbrook. PWSA’s engineering team immediately set out to design and construct a new sewer to restore service to residents on the dead end of Odette Street. This was also an opportunity to separate storm and sanitary sewer service, install more storm drains, and move the sewer out of the hillside and into the street, which is safer and more reliable.
Work began in February of 2019, with the installation of 603 feet of sanitary sewer, 670 feet of new sewer laterals connecting homes to the sewer main in the street, and 591 feet of new storm sewer. This project was particularly challenging, with the construction team working against the natural slope of the street so gravity could do its job conveying sewage. Crews dug trenches nearly 30-feet deep to install the pipe. Work also included new sewer laterals for customers who lost service after the landslide.

To install the new sewers, crews coordinated with Pennsylvania American Water and Peoples Gas to relocate utilities that were in the path of the new, gravity-fed sewer. Our team also worked with each resident to inspect their properties, explain the construction process, and ensure the work completed was to the highest standards. The new storm drains installed in the surrounding area will also help to capture stormwater runoff that is a concern for the Overbrook neighborhood during the rainy season.
”To avoid emergency repair work like this in the future, we’re proactively identifying sewers that are at a high risk of failing or are located on hillsides or under buildings. Using these markers, we can prioritize the most at-risk portions of our system for replacement,” said Executive Director Robert A. Weimar.
PWSA maintains 1,200 miles of sewers throughout its service area, many of which are over 100 years old and are reaching the end of their useful life. In the coming years, the Authority will invest $6.7 million to rehabilitate, relocate or reroute sewer lines located under buildings and bridges or adjacent to steep slopes that are prone to landslides.
