Surface Water Retention

Sustainable drainage systems (SuDS) can be used to first cleanse surface water run-off and then store it both above and below ground. This can be used to re-supply cleansed but non-wholesome water to buildings or landscapes

Rainwater recovery systems, such as Rainstream, can be installed on individual properties or as large scale communal systems within urban and rural developments.


Retaining and re-using rainwater for non-potable purposes such as irrigation and toilet flushing can reduce demand for potable water, and also help to protect our natural resources and landscape.
