Underground detention tanks
The Envirogentle underground modular tank system is fully engineered to comply with Local Authorities stormwater and greywater management requirements. It offers a cost effective, functional underground service tank solution for detention tank, retention tank, water tank, septic tank and grease trap.
Envirogentle underground tanks are strong but lightweight (only 62kg per 1000 litre module). This makes Envirogentle easy to handle for installation, especially in hard to access places.
Also extensive testing by certifying engineers has demonstrated the system’s ability to comply with all relevant requirements including Vehicular Loading (AS/NZS 1170) and Polyethylene Tanks (AS/NZS4766 – 2006).
Through this, Envirogentle has been approved for installation under driveways and high traffic areas making it very practical. There is also no need for deep holes with the Envirogentle tank designed to sit just 300mm under the ground. Because of this, installation is straightforward, especially with the moulded in inlet and outlet pipes.
The modular design of the Envirogentle underground tank system is flexible enabling tanks to be built in 1000 litre increments. Envirogentle tanks are easy to maintain with a unique filter system and easily removable catch pit filter.
Designed and made in New Zealand, the Envirogentle system comes from Rotational Plastics.
