City of Everett • 2024 Comprehensive Sewer Plan • October 2025 Executive Summary • ES-13 Maintenance and Operation Chapter 9 discusses the maintenance and operations (M&O) requirements, activities, and staffing for the sewer system. Additionally, this chapter identifies issues and recommends improvements for the same. The City of Everett Public Works Department is responsible for the M&O and consists of three main work groups: Technical Services Group (TSG), Sewer and Drainage Group (S&D), and the WPCF group. The M&O activities include regular inspection of pump stations, cleaning, and repairs of sewer pipes; CCTV inspection and condition assessment reports; inspections and preventative maintenance of the WPCF equipment; ongoing records management for all components of the system; industrial pre-treatment program, updates to the WPCF’s operation and maintenance manual; and daily laboratory testing of City’s water system. Evaluation of M&O activities as part of the 2024 Plan considered lift stations and the collection system. No M&O issues were identified for the lift stations. The collection system was found to have several issues common to wastewater collection system. Flat parts of the system with shallow grades are susceptible to solids accumulation and ragging. Some areas are known to have high RDII which indicates a condition issue. Water Reclamation and Reuse Chapter 10 provides background on the Reclaimed Water Act and requirements of the Reclaimed Water Rule (Chapter 173-219 WAC) which is the basis of determining water reclamation and reuse in the WPCF. The Reclaimed Water Rule defines three classes of water: Class A+, A and B, based on treatment requirements and use-based performance standards. The use of Class A+ water for potable purposes is not yet permitted in Washington. Class A water can be used in applications where site runoff and public employee contact is likely whereas Class B water has more stringent restrictions for usage. Since the WPCF is unable to meet fecal coliform limits, it does not meet the requirements for Class A or B for reclaimed water reuse. The City does not have any plans to produce or market reclaimed water in the near term as it was determined to be costly and challenging to transport due to the inconvenient location of the WPCF. Capital Improvements Plan The CIP projects were developed to address existing system deficiencies, address regulatory requirements, and provide adequate capacity for projected flows and loads. CIP projects to address immediate needs are presented in a 10-year planning horizon (from 2024 to 2034) and future CIP projects are included in the 20-year planning horizon (from 2034 to 2044). CIP projects for the 10-year and 20-year planning horizons are presented in and . A planning level cost opinion of CIP project implementation is provided. The financial analysis considers the CIP developed for the 2024 Plan and existing City CIP projects.
