Extention Basin

(a.k.a. Extension Basin)

The Extention Basin is a composite of a stormwater detention basin and other stormwater storage basins, linked by defined flow control panels. The other stormwater storage basins are usually used for treatment of pollutants in stormwater, or for the reduction in stormwater runoff by infiltration. It was discovered in 2001 that the total storage volume for all standard basins can be optimized and minimized by high-level, mathematical procedures and standard hydraulic principles.

The EPA has deemed that pollutants in stormwater have an adverse impact on streams, river, lakes and ponds, therefore, the federal government, in the Clean Water Act amendments, has required every State to comply with water quality standards leading to State regulations to control both stormmwater peak flows and stormwater quality. The extention basin is a structural measure that allows developers to meet the new State stormwater rules. It operates, typically, over storm frequencies in the range of 1 year to 100 year but there is no limit to the actal range of operation.

The extention basin is desirable since it minimizes total storage.
