SDS Intellistorm® is a smart rainwater recycling and attenuation system designed to manage stormwater and maximise rainwater reuse using a single tank. It uses live weather data to control water storage and release, reducing mains water use, flood risk, and the need for extra tanks or land.

  • Smart system for rainwater harvesting and stormwater attenuation in one tank

  • Automated control based on live rainfall forecasts and local catchment data

  • Reduces mains water demand and water supply fees

  • Minimises flood risk by releasing water before storms and maintaining tank capacity

  • No extra tank or excavation needed, saving space and cost

  • Compatible with above- or below-ground tanks and a range of filtration systems

  • Tiered redundancy with two mains water backups for reliability

Applications

  • Commercial buildings

  • Industrial sites

  • Community and residential developments

  • Domestic properties

  • Toilet flushing

  • Irrigation

  • Vehicle cleaning

  • Manufacturing and cooling systems

How does it work?

Unlike traditional attenuation systems which temporarily attenuate stormwater and allow a continuous controlled discharge of any collected surface water, SDS Intellistorm® actively empties in accordance with weather forecast data. It provides only sufficient space in the tanks to receive the incoming rainwater and ensures the maximum amount of water for reuse is continuously available .

SDS Intellistorm® puts water reuse well within the reach of every project where SuDS is a planning requirement. Where a new build development needs to consider both flood resilience and water consumption impact, there's no need for separate rainwater harvesting and attenuation systems. 

By combining two systems and using intelligent data, significant savings in construction costs are achieved, while spatial restrictions to accommodate large water storage volumes are mitigated. Plus, end-users achieve ongoing cost savings through water reuse and the wider environment and society benefit from increased flood resilience.
