There is a trend gaining momentum that enables cities and towns to economically control sanitary sewer overflow. The traditional method of installing pump stations throughout a system is being augmented with underground detention systems. Made from large-diameter polyolefin pipe, the systems are economical, easy to install, can be configured to conform to any layout, meet capacity needs, and can last 50 to 75 years or longer.
Most sanitary sewer systems count on pump stations, which are installed at intervals within the collection system. Some collection systems lift sanitary sewage 20 to 70 ft to the treatment plant because the pipe has to be deep in order to continue a gravity flow. This can be expensive. The design, components and installation are costly.
Most municipalities have multiple pump stations that often have pumps of different sizes, from different manufacturers or with different components.
A municipality has to maintain those pumps, which requires manpower, expertise, spare pumps, spare pump seals, spare pump breaker boards and electrical components. This inventory naturally ties up capital and can mean an additional expense for taxpayers.
