This is enabled by storing and using collected rainwater for non-potable applications such as toilet flushing, irrigation, vehicle cleaning, manufacturing and cooling systems, whilst creating storage capacity for stormwater that might otherwise overwhelm and flood the drainage system. The system interprets and assesses weather forecasts along with expected rainfall and local catchment data and responds accordingly.
SDS WaterBank Intellistorm® reduces by as much as £100,000 the cost of integrating water reuse into a new build development where attenuation already exists, encouraging the take-up of water reuse. Cost isn’t the only key factor; the Intellistorm® system presents no additional equipment footprint or civil excavation associated with a second tank, allowing space to be removed as a barrier in the decision to integrate water reuse.
How does it work?
Unlike traditional attenuation systems which temporarily attenuate stormwater and allow a continuous controlled discharge of any collected surface water, our Intellistorm® system 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 are 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.
Furthermore, our Intellistorm® rainwater management system can be extended to incorporate grey water recycling, thereby reducing to an even greater extent the demand on potable water supply, increasing self-sufficiency, reducing carbon footprint and maximising environmental and Corporate & Social Responsibility credentials.

FEATURES & BENEFITS
Reuses water that might otherwise have contributed to flooding.
Limits impact of uncontrolled rainwater on natural environment and engineered drainage infrastructure.
System manages stormwater attenuation and rainwater harvesting using one tank only.
The additional space and storage capacity normally demanded by extra rainwater harvesting volume, together with the costs of associated materials and land take, are avoided.
Live rainfall forecast received in mm/24 hours.
Continuous monitoring of rainfall forecasts ensures any expected changes in weather are accommodated.
Automated calculation of spare capacity for attenuation with programmable safety levels.
Provides control of tank water levels to optimise water reuse efficiency (via predictive weather forecasting). Constantly creates and maintains required tank void.
Releases water into the public sewers before the expected storm event.
Minimises the load on the public sewers during storm events.
Sub-metering and automated meter reading, including remote production volume monitoring, available via SDS SYMBiotIC™.
SDS SYMBiotIC™ provides 24/7 client access to accurate rainwater harvesting data and mains water usage via a secure web portal dashboard.
Choice of attenuation tank manufacturing material according to site requirements or specification preferences.
System can be used with any type of attenuation tank.
Tiered redundancy system allows two mains water backups, operating on separate power supplies.
Ensures supply of water even in the event of system component failure.
Valves can be installed on the tank outlets before the flow controller.
Compatible with gravity drained systems. For systems where the tanks are below the level of the sewers a pump is installed.
Low energy pumping.
Reduces running cost and carbon footprint.
Choice of attenuation pump capacity.
Any SuDS discharge limits set by the Water Company or Local Authority are adhered to.
Pump typically submerged in underground tank installations or mounted above- ground when tank is installed in a building basement.
Flexible pump locations ensure the system is suitable for all types of project and above- or below- ground installations.
Bespoke transfer pump sizes available on request.
Increases or decreases the amount of water supplied for reuse as required.
System reverts to standard attenuation operation if any safety parameters are exceeded.
Compatible with a range of water filtration and treatment systems.
Ensures that when configured as a rainwater harvesting system the delivered water meets the required quality standards of multiple supply purposes.
Custom designed and supplied to the requirements of each site.
Enables controls, measures and monitoring parameters to be built into the system.
