    Drainwell underground stormwater retention tanks from NovaPlas

    Novaplas Pty Ltd

    NovaPlas Pty Ltd  presents an economical solution for stormwater retention with Drainwell drainage cells.

    The Drainwell underground stormwater retention tank system comprises of lightweight plastic Drainwell modules that can be easily installed to provide an ecologically sustainable unlimited rainwater storage facility.

    The drainage modules are stacked onto a plastic sheet liner wrapped around the tank and sealed for stormwater retention. The stored water can be subsequently used in gardening and various greywater applications.

    Drainwell stormwater tanks can also be used for the detention of excess stormwater by storing the water and allowing a slow release into stormwater pipe or channel systems and surrounding ground.

    The Drainwell modules are assembled and stacked onto geotextile filter material in the excavated ground void, wrapped around with the geotextile fabric and back filled. The panels making up the Drainwell module have moulded rings, which can be simply cut round with a handheld jigsaw to allow pipes to be fitted.

    Drainwell stormwater retention tanks are ideal for controlling stormwater flow from paving, civil works, reservoirs, golf courses, race courses and sports fields among others.

    With the new SUDs (Sustainable Urban Drainage) sustainability codes being released by many local authorities, the Drainwell stormwater retention tanks are being considered as easy to install and cost-effective underground stormwater management systems for residential, commercial and industrial projects.
