The Global Water EcoTreat Full Retention Separator is an oil separator that effectively treats polluted run-off water. It is one of Global Water's multiple stormwater treatment devices available. 



Global Water's EcoTreat Bypass Separator is designed to treat stormwater run-off from paved areas where low levels of hydrocarbon residuals and gross pollutants are present whilst allowing high flows to pass without restrictions. 

The EcoTreat Bypass Separator is suitable for primary and secondary treatment in low risk areas, removing suspended solids, silt, hydrocarbons and nutrients whilst preventing on-site flooding from storm events.
