SDS Rainwater Recycling

Key Benefits
Rainwater Recycling System
Rainwater recycling is the collection, storage and reuse of rainwater that typically would otherwise flow down gutters into the drainage network.
SDS supplies fully automated systems that provide an integrated rainwater management and delivery platform to control the collection, treatment and distribution of rainwater to an end user application.
SDS commercial and domestic rainwater recycling systems are able to reduce consumption and improve efficiency of water use, saving money, enhancing corporate sustainability and protecting the local environment, as well as reducing both mains water consumption by up to 30% and also the building’s carbon footprint.
Rainwater recycling can be incorporated into new build developments and properties, such as at Southbank Place and retrofitted to existing buildings, such as at Isles of Scilly Flowers, where there is sufficient roof space to capture rainwater.

Automates control of tank water levels to optimise water reuse efficiency.
How Does It Work?

The diagram above represents our Rainwater Recycling system in a school environment.
By assessing the site’s geographic and infrastructure suitability, SDS can design and install a bespoke system to collect and filter rainwater, feeding it back into the property through a simple yet robust treatment system. This ensures that only the cleanest, soft water is utilised for non-potable purposes such as flushing toilets, vehicle washing and irrigation.
SDS Rainwater Recycling systems’ control software incorporates a level sensor which ensures rainwater is prioritised as the primary water source. An integral AA-rated break tank ensures a constant water supply is achieved by intelligently switching to mains water when rainwater is unavailable.
Domestic rainwater recycling systems are normally installed where the additional benefit of diverting surface rainwater away from the otherwise overloaded drainage systems can be deployed, thereby reducing the potential for flooding. They are, therefore, most typically retrofitted to existing single residential properties or, in a community-wide scheme, multiple properties.
