Even treated wastewater impacts water quality in Puget Sound, contributing nutrients that worsen dissolved oxygen and ocean acidification, as well as pharmaceuticals that have been found in juvenile salmon. We are ensuring that Ecology requires municipalities to transition to advanced wastewater technology, both addressing existing problems and preparing for future growth now. We strongly advocate for sustained investments in all water infrastructure.
Puget Sound No Discharge Zone
The Puget Sound No Discharge Zone rule prohibits ships and boats from discharging raw or partially treated sewage across 2,300 square miles of marine waters and the continuous waters around Lake Washington and Lake Union. After six years of public process and tens of thousands of supportive comments from you and members of our coalition, the rule went into effect on May 10, 2018. Along with our partners, we continue to defend the No Discharge Zone from challenges by industry and the Trump administration.
