Buffatank™ systems are custom manufactured from prefabricated Hel-Cor™ modular units that are connected on-site with simple coupling bands. Buffatank™ stores stormwater underground, saving valuable real estate on your project site. Buffatank™ can be placed under lawns, gardens or driveways. Underground storage provides a safer and more aesthetic stormwater storage solution.

Detention

Buffatank™ can reduce local and downstream flooding by retaining storm events and releasing water at a controlled rate through an orifice plate.

Retention

Buffatank™ can be designed to retain stormwater runoff for later irrigation of parks and gardens — making better use of this valuable resource.

Custom manufactured

Buffatank™ systems are custom manufactured to the requirements of the project. Hel-Cor™ pipe is the system’s principal component. A typical system may include:

Access risers
Ladders
Lock down grate and frames
End walls
Orifice and litter screen
Silt trap
Inlet stubs
Outlet stubs
High Early Discharge (HED) chamber
Elbows and manifold units

Buffatank™ systems are manufactured to comply with the design requirements of local government and waterway catchment authorities.
