Richland, Washington: water and wastewater capital improvement projects
19 line items · $83M · starting 2026 · 1 plan
Richland's published capital plans list 19 water, sewer and wastewater line items with a combined planning budget of $83M, of which 9 items worth $34M sit in the wastewater and sewer departments. The largest single item is Downtown Connectivity Transportation Improvements at $24M (2025–2026). The ten largest items are listed below; the full list with descriptions and page references is in Klarifi.
A capital improvement plan (CIP) is a city’s multi-year budget for building and replacing infrastructure. The water, sewer and wastewater sections list each project with its budget and the years it is funded, which makes them the earliest public signal that a plant, pump station or pipe network is about to be upgraded, usually two to four years before a contract is awarded.

Sources and methodology
Budgets and years are as published in Richland’s capital improvement plan or adopted budget. Klarifi extracts the water, sewer and wastewater line items from the published document, keeps the page reference for each one, and assigns a project type from the title and description with a keyword classifier. Figures are planning budgets, not awarded contracts, and can change when a plan is re-adopted.
Documents: CIP 2025–2030 (19 line items).
