Storm water management

Storm Water Management Planning

Stormwater management is a mechanism for controlling stormwater runoff for the purposes of reducing downstream erosion, water quality degradation, flooding, and mitigating the adverse effects of the changes in land use on the aquatic environment. HN offers this service which includes all aspects associated with the planning, design, maintenance, and regulation of facilities that collect, store and convey stormwater.

Sustainable drainage is a concept that includes long-term environmental and social factors in decisions about drainage. It takes account of the quantity and quality of runoff, and the amenity value of surface water in the urban environment. Many existing urban drainage systems can cause problems of sustainability. We recognise the benefit Sustainable Urban Drainage Systems (SUDS) techniques offer and therefore incorporate them into our planning and designs with the following objectives in mind.

  • Flood mitigation
  • Protecting receiving water bodies
  • Promoting multi-functional use of stormwater management systems
  • Developing sustainable stormwater systems
