Water management strategies can no longer simply begin and end with the requirements of your project. As part of today's holistic approach, they must integrate with wider policies on water collection and control established by Councils, Internal Drainage Boards, Highways Authorities and the Environment Agency
Storage & Management
Storage is essential in SUDS design because it serves to remove or arrest water that could otherwise go on to overwhelm drains, sewers and rivers during extreme storm events or periods of sustained rainfall. It can comprise of large volume, underground tanks of the kind used in major commercial, civils and infrastructure projects, or shallower 'modular' techniques. We will advise you on which products are right for your project and on how they integrate with other systems as part of water re-use, attenuation or treatment processes.
Re-use and control of Rainwater
In parts of South East England there is less available 'fresh' water than in countries surrounding the Mediterranean.
Non-domestic buildings are currently assessed under the Building Research Establishment Environmental method (BREEAM 2009) and whilst this is currently not mandatory, it is not possible to achieve the highest rating of 'excellent' through water efficiency techniques alone. This has led to an increase in demand for rainwater re-use systems on commercial projects.
Rainwater re-use systems reduce mains water demand by around 80% in commercial and other infrastructure buildings used by the general public such as schools, hospitals and leisure centres.
Efficient rainwater re-use systems dramatically reduce the cost associated with mains water. Payback periods of around two to five years depending on the project specifics can easily be achieved.
Treatment of Surface water
The EU Water Framework Directive sets clear targets to reduce levels of diffuse pollution from petrochemical deposits, agricultural run-off and industrial waste. These targets are incorporated in a variety of domestic legislation, including the Drinking Water, Ground Water and Sewage Sludge Directives and the Flood and Water Management Act.
