 Althon Ltd offer a Range of Sustainable Urban Drainage Systems (SUDS) for the Collection, Treatment and Dispersion of Surface Water and Roof Water.

Sustainable Urban Drainage (SUDS) is increasingly being preferred to Traditional Drainage systems for the Effective Management of Surface Rainwater run-off.

The Althon SEL Source Control System is lightweight and installed Above Formation Levels and Contaminated zones – Typical Installation is at less than 500mm deep.

Our Source Control System dramatically Reduces the level of Earthworks required by creating a structural void within the Sub-Base layer Substituting Expensive Imported Aggregates.

The Althon SEL Source Control comprises a series of treatment phases to provide Source Control to meet the requirements of current Sustainable Urban Drainage (SUDS) Guidelines and Legislation.

The main Benefit of Source Control is that Water is Treated and subsequently Attenuated or Infiltrated as close to the Source and Surface as possible
