Sewickley Water Authority to begin line replacement

| Wednesday, July 23, 2014, 9:00 p.m.

Starting Monday, the Sewickley Water Authority will begin undertaking its first of two projects totaling $780,300 over the next several months, the authority's manager said.

About 2,200 feet of 10-inch cast-iron pipe installed in 1899 will be replaced with new 12-inch pipe along Centennial Avenue, from Blackburn Road to Nevin Avenue, authority manager Brian Hohman said.

Centennial Avenue will remain open to traffic, but it will be limited in sections as work progresses, Hohman said. Parking also will be restricted in work zones.

“The goal is to minimize the effect the work has on the neighborhood,” Hohman said.

In addition to main line replacement, new water-line-to curb valve installations will occur for customers, he said.

In addition to improving water service for Centennial Avenue customers, the work also will benefit customers on connecting streets, including Blackburn Road, Murray Street, Locust Place, Broad Street, Lincoln Place, Mulberry Street, Straight Street, Fountain Street and Nevin Avenue, Hohman said.

He said about 125 customers will receive benefits from the project.

Work is set to last about six weeks.

In early September, the authority will begin a $172,800 water-line replacement project in Sewickley and Glen Osborne.

The work will take place along Route 65 from Dippold Street to Osborne Plaza, Hohman said. The work will be completed outside of a PennDOT right-of-way zone and will not affect traffic.

About 1,600 feet of 6-inch cast-iron pipe dating to the 1930s will be replaced with 8-inch modern piping, he said. That project is expected to last about three weeks.

Work on both projects will happen for 10 hours each day for four days a week, Hohman said.

The authority — which serves all residents in Sewickley, Glen Osborne and Haysville; most residents in Sewickley Heights; and portions of Aleppo and Edgeworth — has spent more than $2 million since 2011 upgrading aging water lines across the organization's coverage area, Hohman said.

Since then, improvements have been made to lines along Scaife Road, Blackburn Road, Backbone Road, Persimmon Road in Sewickley Heights; near Sewickley Heights Borough Park; Nevin Avenue in Sewickley; and Center Street in Haysville.

Less than 5 percent of the system is part of original lines placed in the late 1800s, Hohman said.

Lifespan for new lines can range from 80 to 100 years.

Hohman said lines being replaced are “past their life cycle.”

The work is part of a five-year plan to replace and improve the Sewickley Water Authority's coverage area, he said. Projects are determined based on priority factors including age and need for replacement. Work along Ferry Street wrapped up this summer.
