Description Studies have shown that municipal sewage treatment plants are significant contributors to these problems. This report presents an evaluation of two approaches to reducing treatment plant discharge of nutrients to surface water:


  • Improving treatment processes to remove more nitrogen or phosphorus and thus reduce their concentration in the treatment plant effluent.

  • Improving treatment processes to achieve effluent quality suitable for use as reclaimed water to recharge groundwater sources, rather than being discharged to surface waters.

  • The effectiveness and cost of various technology upgrades were evaluated for generic models of the numerous types of treatment plants used in Washington State. The results of the evaluations can be used by regulatory agencies, engineers, planners and the public to assess the likely implications of such treatment plant upgrades.
