Our 7000 Litre Underground Rainwater Harvesting System is an automatic system designed for collecting and suppling water on demand in both domestic and commercial situations.

This system consists of an industrial strength MDPE (Medium Density Polyethylene) tank complete with pipework connections, self priming inline pump and water filter. This system offers great savings compared with mains water consumption and certainly helps you do your bit for the environment.

The 7000 litre underground water tank must be fully encased in concrete if installed in clay soil or high water table area and is only designed to take pedestrian traffic over it once it is installed. There are multiple inlet positions on top of the tank that can accept fittings up to 4", this tank also has a 500mm extended neck which can be cut down if required. 

The 7000 Litre underground Water Tank is suitable for domestic, agricultural and industrial uses where WRAS approval is NOT required.

Please make sure you read all installation instructions before purchasing this system.
