What changed

Pasco adopted water and sewer adjustments after a 2025 utility rate and connection fee study. The city frames the changes around public health, reliability, and infrastructure funding.

For commercial and industrial users in the Tri-Cities region, connection fees matter too because they affect expansion projects, new buildings, and water-intensive tenant improvements.

Commercial impact model

A business paying $7,500/month for water and sewer should test 5%, 8%, and 12% scenarios against its actual account. Those scenarios translate to $4,500, $7,200, and $10,800 per year in added operating expense.

For new construction or expansion, the 2027 connection-fee update can affect project economics separately from monthly utility bills.

What operators should do

Existing businesses should compare pre-March and post-March bills using the same billed volume. Developers and industrial users should request updated connection-fee assumptions before finalizing pro formas.

Smart Valve belongs in the operating model because any reduction in metered volume helps offset both near-term rate increases and the long-run cost of capacity-driven utility investment.
