What Northshore Utility District does
Northshore Utility District (NUD) is a special purpose public agency organized under Washington State law that provides water distribution and sewer collection services across a 17-square-mile service area at the northeast end of Lake Washington. Formed in 1947 as King County Water District Number 79, the district merged with the Northeast Lake Washington Sewer District in 1979 and adopted its current name in 1991. It serves more than 87,000 residents and businesses through approximately 22,000+ service connections spanning portions of Kenmore, Bothell, Lake Forest Park, Kirkland, and Woodinville. The district operates 281 miles of water mains, 261 miles of sewer conveyance pipes, 11 lift stations, 3 water pump stations, and 8 storage tanks with combined capacity of 29 million gallons. Wholesale water is purchased from Seattle Public Utilities (Tolt River Watershed source) and sewage treatment is provided by King County.
The district generates revenue primarily through bi-monthly recurring water and sewer service fees to residential and commercial customers, supplemented by connection and availability fees ($135 per availability certificate), permit and inspection fees, and development service charges for new main extensions. Rates are reviewed annually and adjusted based on cost of service; water rates increased 4.5% and sewer rates increased 5.8% in 2025 to achieve full cost recovery. Distribution is direct-to-consumer via a Customer Web Portal, phone, in-person, and mail payment channels, with no intermediary. The district is governed by an elected five-member Board of Commissioners; Ethan Maiefski was appointed General Manager on May 6, 2025 after a 25-year career within the district. Customer-facing digital tools include the NUD Utility Map (UMAP) for interactive access to utility drawings and project information, the Customer Web Portal at paymybill.nud.net for account management, and an opt-in text alert service for service notifications. No AI or advanced machine learning capabilities are evidenced in the source material.
