Cost effective, simple, smart Planning - Rain Activ provides developers with a new tool to maximise building area and reduce SuDS costs. By controlling the discharge rate at source, expensive and ‘space intensive’ secondary storm attenuation devices such as balancing ponds and wetlands can be minimised or even excluded from plans. • Ultra-low discharge SuDS system. Installation - Rain Activ arrives fully assembled ready to fit. The use of single piece, shallow dig tanks mean even large tanks (7500L) require just 1.5m of excavation. Costs are further reduced as no concrete or specialist training is required. • Peak discharge rates as low as 0.05 L/sec per property. • Primary solution reduces secondary SuDS infrastructure and costs. Maintenance - Rain Activ contains no moving parts and is fully self cleaning. Once installed, all maintenance (typically one annual visual check) should be the responsibility of the homeowner. Add Rainwater Harvesting. Rainwater Harvesting can make a fantastic addition to a new development. Rain Activ can be configured to act as a dual purpose SuDS and Rainwater Harvesting system for a relatively small additional cost. By simply adding a pump and management unit, Rain Activ can be turned into a full domestic Rainwater Harvesting system. A full domestic system reduces mains water consumption by up to 50%. Whilst latest management systems cost less than 1p per person per day to run. From the UK’s market leader in domestic rainwater harvesting systems. • Each system individually calibrated to site requirement. Micro Drainage™ calculations included. • Can be used in combination with Rainwater Harvesting.

A revolutionary new SuDS device with incredibly low discharge rate Ultra low discharge rates, 50X lower than some Vortex flow control systems Graph Showing Flow Rate vs Head Height out of the Rain Activ What is Rain Activ? Rain Activ is a totally new concept within the storm attenuation market. Utilising shallow dig underground water tanks as well as a filtration and controlled discharge module. Rain Activ collects water from the roof and removes debris via a self-cleaning filter. Once inside the tank, the clean water is attenuated and discharged slowly at a calculated rate through an orifice....
