This Vital Sign helps us track progress on management of onsite sewage systems and the protection measures put in place to protect nearshore areas. Onsite sewage systems, commonly known as septic systems, are widely used around Puget Sound to treat sewage from properties not served by municipal sewers. Leakage of sewage from septic systems into Puget Sound water causes poor water quality and can lead to public health risks.
