water treatment plant

WNMP sector objective

To safeguard the capacity to safely and effectively treat and discharge surface water runoff and wastewater.

What is the surface water and wastewater treatment and disposal sector

The Surface Water and Wastewater Treatment and Disposal sector includes wastewater’s:

  • collection
  • transport
  • treatment, and
  • disposal.

It covers sewers, sewage treatment works, industrial effluent and combined sewer overflows. The WNMP recognises that the provision of infrastructure, both through:

  • terrestrial planning
  • marine planning

for the SWW sector are key activities. The ongoing function of the SWW sector is critical. Other sectors rely upon healthy and clean water bodies for their own activities.

WNMP sector policies
