Effective Permeable Pavements

Permeable paving is a surface water drainage technique which is promoted by many UK planning departments & LLFA's as an integral component within a sustainable drainage system (SuDS). The incorporation of permeable paving into the surface water drainage design can assist developers in achieving a successful planning application.

SEL has developed the SEL Source PP range of products to simplify the design and enhance the efficiency of permeable pavements. These products can standardise construction depths, offer enhanced hydrocarbon treatment and optimise the attenuation potential within voided sub-base of individual catchments. They also allow permeable pavements to be utilised on sites which are unsuitable for infiltration and sites with gradients.

Attenuation Tank Solutions

Attenuation is a surface water drainage technique which is promoted by many UK planning departments as an integral component within a sustainable drainage system (SuDS). Currently, most UK planning departments limit the discharge to sewer for new housing developments to ease the burden on existing aged sewer networks. The incorporation of robust attenuation strategy can assist developers in meeting these targets.

SEL has developed the SEL Source AT range of products to simplify the design and enhance the efficiency of attenuation. These products can standardise construction depths, offer enhanced hydrocarbon treatment and optimise the attenuation potential of individual catchments. They allow shallow and deep installation to enable Engineers to overcome site specific issues in the ground.

Effective & Efficient Soakaways

Sustainable drainage systems are designed to control surface water run off close to where it falls and mimic natural drainage as closely as possible. They provide opportunities to reduce the causes and impacts of flooding; remove pollutants from urban run-off at source; combine water management with green space with benefits for amenity, recreation and wildlife.

Particular types of sustainable drainage systems may not be practicable in all locations. SEL has developed the SEL Source SA range of products to simplify the design and enhance the efficiency of soakaway systems. These products offer treatment at source and enhanced hydrocarbon treatment.

Not all sites are suitable for soakaways, percolation tests should be carried out in accordance with BRE Digest 365 or CIRIA guidance R156 to determine suitability.

Car Park Sustainable Drainage (SuDS)

SEL car park SuDS solutions apply the principles of Sustainable Drainage and incorporate a series of treatment phases specifically developed to provide the ideal source control solution to meet the robust requirements of LLFA's, current guidelines and legislation relating to SUDS. The main design principle we use is 'Source Control' the cornerstone of good Sustainable Design

SEL can provide technical assistance to determine the correct way forward for your development whether it be Office, Retail, Warehousing, Industrial, Leisure or a School.

SEL car park SuDS can integrate  with green roofs, blue roofs, detention ponds, swales, permeable paving, rain harvesting, filter trenches, infiltration, voided sub-base attenuation, modular attenuation, refuelling area containment, oil interception and treatment and vehicle washdown areas.
