Major Sewer Pipeline Upgrade Underway  
May 07, 2008 08:04 AM

As part of its 10-year, $67.8M Capital Improvement Program, the District recently approved a contract to design and bid the construction for over two miles of upgrades to sewer pipelines. The oldest pipelines in the project area are nearly a century old. The pipeline improvements are designed to help prevent sewage leaks and inflows of stormwater through cracks that can overload the treatment plant and cause sewage overflows.

Many Benefits for Customers

The project provides customer benefits, among them: increased reliability; environmental and public health safeguards; lower maintenance costs; less infiltration of storm waters; and prevention of overflows, spills and treatment plant overloads. Priority to Minimize Construction Impact on Public

• The District will evaluate a variety of technologies to limit the impacts on customers. In some areas, the District may reline the pipelines from the inside, in other areas, use a technique in which a flexible pipe is pulled through the existing pipeline without extensive surface digging. In other areas, traditional trenching may be the best method to use.
• The contractor will upgrade or replace the pipe incrementally. The project will move in sections so that disruptions and inconvenience will be limited to the sections being worked on.
• Construction hours will be limited, strict dust and dirt controls will be in place and access will be maintained to homes and businesses.
• Public hearings will be held during the design stage to obtain input from customers and keep them informed.
• A project manager will be available during construction to answer questions or resolve any issues that arise.
