SDS smart rainwater management brings multiple benefits to primary school

OVERVIEW

This pilot project established the opportunities for, and barriers to, the application of integrated SuDS technologies in a school setting.

The rainwater management and reuse system installed by SDS holds back stormwater from the drainage network during peak storm conditions, reducing the frequency with which the CSO discharges untreated wastewater into the River Exe.

The scheme included the installation of a SDS WaterBank™ Intellistorm® system, equipped with SDS SYMBiotIC™ remote sensing and monitoring devices to provide data and analytics.

WHAT WE DID

The area of roof identified as suitable for the catchment of rainwater measures approximately 600m2 and represents approximately half of the total roof area.

SDS installed a 15m3 tank below-ground, equipped with a mains water back-up.

Water in the storage tank is pumped via ultra-violet treatment to the school’s toilets, replacing potable supplies for flushing purposes.

The tank overflows to a surface SuDS feature, a swale and raingarden, which also receives rainwater directly from the other half of the school roof.

RESULTS

SDS SYMBiotIC™ devices, situated in an adjacent control box, provided data monitoring and the quantification of a number of indicators, including evidence of peak flow attenuation, reductions in potable water consumption, cost savings to the school, and estimated annual carbon reduction of 139kg CO2E.

This scheme supports the primary goal of South West Water’s ‘Downstream Thinking’ approach to manage stormwater in sustainable and innovative ways.
