Why Are Water Rates Rising?

Aging infrastructure, enterprise fund rules, and what the peer cities pay

Enterprise Funds: Rates Must Cover Costs

Moscow's water, sewer, and sanitation systems operate as enterprise funds - they must be self-supporting. No property tax money covers water system operating costs. When infrastructure ages and needs replacement, rates go up.

Moscow's water infrastructure was largely built in the mid-20th century. The 10-year Capital Improvement Plan (2025-2034) includes $18.6 million in water projects and $71.6 million in sewer projects. These include well rehabilitation, transmission line replacements, and a major upgrade to the Water Resource Recovery Facility (WRRF).

The WRRF Ultraviolet Treatment System alone costs $5.1 million (FY2026). The Headworks Improvements project is $7.1 million (FY2031). These are not optional - they are required to maintain state and federal permits.

Moscow's residential fixed water charge ($44.78/month for a 5/8" meter) is higher than Coeur d'Alene's ($11.22 for 3/4" meter) but comparable to Lewiston ($39.00 for 3/4" meter). The difference largely reflects how each city structures its rate - Moscow puts more cost into the fixed charge versus usage tiers. Sewer rates are similar across all three cities.

Why Is Moscow's Fixed Water Charge So High?

The fixed charge covers the cost of maintaining the system regardless of how much water you use - pipes, wells, pumps, meters, and staff. Moscow chose a higher fixed charge model, which spreads infrastructure costs more evenly across all customers. Cities that use lower fixed charges (like CdA at $11.22) recover more cost through the per-unit usage charges.

For a typical household using 500 cubic feet per month, Moscow's total monthly water bill (fixed + usage) comes to about $63.73. Lewiston is similar. CdA is lower because their usage charges are also lower - their system serves a larger and faster-growing customer base that spreads costs further.

Moscow has no access to a regional water authority. Every capital project is funded locally through rates, reserves, and occasionally revenue bonds. There are no grants that cover routine pipe replacement.
