Soakaway Systems

SUDS best practice limits the flow of rainwater which runs off a site or is piped away, protects local watercourses from the contamination carried in surface runoff, encourages natural groundwater recharge (where appropriate), and reduces the likelihood of downstream flooding. 

The Building Regulations Approved Document H3, Rainwater Drainage, which came into effect on 1 April 2002, prioritises drainage requirements. In short, it requires that rainwater from the roof of a building or from a paved area may either be gathered for reuse or be discharged into one of the following, listed in order:
 
(a) an adequate soakaway or some other adequate infiltration system; or, where that is not reasonably practicable,
(b) a watercourse; or, where that is not reasonably practicable,
(c) a sewer.
 
In other words, the traditionally preferred method of rainwater disposal, ie totally discharging to a sewer, may now only be considered after other forms of reuse or drainage have been considered. The Building Regulations also provide guidance on the construction of rainwater harvesting systems for the first time.

Stormwater Solutions Polystorm and Polystorm Lite are lightweight modular water storage cells with a high void ratio that can be used for either attenuation or infiltration of stormwater in residential, commercial, industrial and retail applications. The system facilitates quick and easy assembly on site where multiple configurations can be formed from standard stock items. A full range of silt traps, flow control units and adaptors is available to complete the system if required. If you would like a site-specific estimate please contact us with your enquiry.
