ENGINEERING — Berryman & Henigar Firm Gets La Mesa Sewer Contract

LA MESA , San Diego-based Berryman & Henigar, a municipal professional services firm, was awarded a design engineering services contract to assist the city of La Mesa in preparing plans and construction documents for the city’s sanitary and storm sewer improvements.

Driss Elwardi, the city’s senior civil engineer, said the work was a big priority for the city.

“Some of our sewer system dates back to the early 1920s and some of the old concrete pipes were installed between 1912 and 1947. They have a plastic liner that gets pushed in with groundwater or roots, making it very difficult to clean and maintain,” he said.

The city will replace 6,200 linear feet of sewer pipe this year. The remaining 72,000 feet should be completed over the next decade, Elwardi said.

Sewer pipe construction is slated to begin this summer and will cost between $900,000 and $1 million.

Berryman & Henigar is also designing sewer system improvements between Lemon Avenue and La Mesa Boulevard, and for the 7000 block of Pearson Street, said Keith Gillfillan, a project engineer.

“The current sewer alignment has lots of angle points, twists and turns beneath residential dwellings and a convalescent complex,” he said. “The new design will straighten the sewer line, which will help to alleviate any potential sewage overflow and backups. Extensive root intrusion on Pearson Street has also led to private property damage, which will also be mitigated.”

Another major portion of the design project is developing a design alternative that will either incorporate or replace a 60-inch corrugated metal pipe.

When completed, the pipe will be able to accommodate a 100-year storm , a storm so severe that, in theory, it could only happen once every 100 years.

Berryman & Henigar has more than 300 professionals serving public agencies from 13 offices nationwide. Services include municipal engineering, finance, community development, construction management, and E-government.

Engineering News-Record ranks Berryman & Henigar as one of the top 250 consulting engineering companies.
