The Speidel 50-50 system is a cost effective dual purpose rainwaterstorage tank and stormwater attenuation systemfor both domestic and commercial environments..

The system incorporates a simple sealed overflow siphon which has acontrollable orifice plate drilled tosuit site conditions and requirements.

An available option is also the patented Speidel groundwater valve, allowing all tanks to be sited in areas of high water table. This also means no expensive concrete back-fill for tanks. They are half back-filled with sharp sand or rounded stoneand then excavated material without stones or rocks. This has a marked effect on reducing the costs of installation when compared with other tanks on the market.
