The City of Arlington has adopted the 2017 amendments to the 2015 Comprehensive Wastewater Plan (CWP). The CWP fulfills state law (WAC 173-240-050) by detailing how the City will safely and efficiently operate our sanitary sewer and wastewater treatment systems for the next 10 to 20 years. The amendment is necessary to assure consistency with a concurrent amendment to the City’s overall GMA Comprehensive Plan, which defines how the City is planning to grow.
