Drought Mitigation

SDS rainwater and grey water management systems help to counter water scarcity by providing an alternative source of supply for non-potable applications where increasingly expensive drinking water is not required.

Rainwater and Grey Water Recycling

The collection and storage of rainwater in rainwater harvesting tanks or water butts, for the purpose of reuse, helps to protect local rivers and reservoirs from their over-abstraction in meeting a growing population’s increasing demand for drinking water.

SDS Drought Mitigation Solutions

SDS rainwater and grey water recycling systems provide a source of water that can be used for non-potable purposes such as irrigating a garden or grounds, flushing toilets or supplying a washing machine.

During storm events in particular these systems provide the additional benefit of diverting surface- and waste- water away from a sewer system that might otherwise be overwhelmed, thereby reducing the potential for localised flooding. Consequently, rainwater harvesting systems are often retrofitted to multiple existing individual residential properties on a community-wide level, in order to maximise their collective attenuation capacity.

Pre-existing stormwater attenuation tanks can also be repurposed to make available a supply of non-potable water, subject to suitable treatment prior to reuse.

Community Rainwater and Grey Water Recycling

As the shortfalls in water availability intensify householders will inevitably be amongst those required to reduce their potable water consumption.

In the above diagram dual feed pipework allowing potable and non-potable water to be supplied to domestic premises separately, although not currently legalised, will most surely become a prerequisite of new housing developments.

In the diagram above six residential properties share a single tank which stores rainwater collected from each roof and is either supplied, or made available, to the properties as and when it is required.

Did You Know?

The whole of the UK is threatened by water scarcity with 7 out of 17 regions expected to experience severe water stress by 2030.*
By 2050 England is forecast to require an additional 5 billion litres of water daily**.

Rainwater and Grey Water Combined Recycling System

Both rainwater and grey water are collected from multiple source points across a variety of building types, sizes and occupancies, treated and stored awaiting reuse as a singular non-potable water supply.
