SDS Intellistorm® helps a site to maximise water reuse and reduce discharge to drain. This is enabled by intelligently storing and using collected rainwater for non-potable applications such as toilet flushing, irrigation, vehicle cleaning, manufacturing and cooling systems.

SDS 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; SDS Intellistorm® 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, 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.

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.

Daily rainfall forecast received in mm/24 hours.
Continuous monitoring of rainfall forecasts ensures any expected changes in weather are accommodated.

Automated attenuation void calculation.
Provides control of tank water levels to optimise water reuse efficiency (via predictive weather forecasting). Constantly creates and maintains required tank void.

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.

Compatible with above- or below- ground installations.
Provides flexible design/usage.

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.

Powder-coated steel or HDPE fabrication.
Choice of tank manufacturing material according to site requirements or specification preferences.

Low energy pumping.
Reduces running cost and carbon footprint.

Choice of pump capacity.
The system delivers the amount of water the project calls for. Any SuDS discharge limits set by the Water Company or Local Authority are adhered to.

Flexible pump location.
The pump is usually submerged when using an underground tank, or mounted above ground for example when using a tank located in the basement.

Bespoke pump sizes available on request.
Increases or decreases the amount of water supplied.

Safe-to-fail operation.
System performance is not compromised by power outages.

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.
