A framework for integrated sewer management in buildings
Posted: Friday 25th April 2008
At a time when climate change and future housing growth will present new demands, it is crucial that sewer networks are able to operate efficiently. The integration of sewer system design with wastewater treatment plant design will achieve more sustainable and more cost-effective wastewater management.
BS EN 752:2008 Drain and sewer systems outside buildings
Although many drain and sewer systems started out as combined systems there are strong arguments for considering the separation of foul wastewater and surface water. However, the connection of wastewater drains to surface water drains is a common occurrence during conversions and extensions in urban areas served by separate drainage systems. Incorrect connections can cause chronic and severe pollution of watercourses.
The separation of effluents allows for the different treatment for each element of wastewater, providing more environmentally friendly solutions. This concept is included in the approach of integrated sewer management.
BS EN 752:2008 Drain and sewer systems outside buildings provides a framework for the design, construction, rehabilitation, maintenance and operation of drain and sewer systems outside buildings.
BS EN 752:2008 specifies the functional requirements for achieving these objectives and the principles for strategic and policy activities relating to planning, design, installation, operation, maintenance and rehabilitation.
