Retention & Detention Tank Systems

Our modular below ground tank systems can provide from 450 gallons (1710 L) to many thousand gallons of retention / detention volume for single home residential up to commercial industrial stormwater infrastructure. A variety of stormwater filter chambers are also available from BARR to screen debris from sustainable drainage and infiltration systems and even remove and absorb hydrocarbons.

Below ground infiltration chambers for onsite infiltration of stormwater are ideal to redirect stormwater runoff from overwhelmed city drainage systems and wastewater treatment plants and also prevent pollution from entering centralized drainage systems and into waterways, lakes and oceans.

Contact a BARR Stormwater components specialist today to help configure the system you require.

Note: The systems listed below can have extension tanks (available to match all of the sizes below) attached in a modular fashion to expand the capacity of the systems.
