Provider briefing
How this utility’s billing works
City of Castroville Utility Billing & Customer Service operates as a municipal department serving Castroville. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Increasing block tiers with a customer charge. The City's FY2026 water-management schedule shows residential inside-city customer charge $30 and usage blocks of $5.35 for 0–5,000 gallons, $5.67 for 5,001–10,000, $6.20 for 10,001–20,000, then higher blocks through over 50,000 gallons; separate outside-city and commercial schedules apply.. Bills are generated monthly. charges are billed on the 10th day of the month following usage; the policy defines the billing period as the 28th of the previous month through the 27th of the current month. payments are due by 5:00 p.m. on the 25th, or the next business day when applicable., and a typical residential cost reference is Using the published inside-city FY2026 schedule, water is approximately $56.75 at 5,000 gallons and $68.09 at 7,000 gallons before wastewater and other charges. The FY2024 adopted wastewater schedule lists a $30 residential customer charge plus $16.668 per thousand gallons above the two included units; if the winter-average usage is 5,000–7,000 gallons, the indicative combined water/wastewater total is roughly $137–$181 before other utility charges and any current ordinance changes.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
Residential wastewater uses winter averaging: actual water usage for October through January is reviewed, the two highest months are discarded, and the remaining two months are averaged. That average is billed in 1,000-gallon increments using the current fee schedule. The City policy permits staff to substitute a preceding three-year wastewater average for an isolated, verifiable leak or anomaly when the customer submits a written request within 60 days of the bill, documents the leak with a permit, plumber report, photographs, or repair receipts, and confirms the issue is resolved.
Meter and infrastructure notes
Meter data is pulled on the 27th of each month for monthly billing covering the 28th through the 27th. Meters requiring manual reads are read during the five business days before the 27th; re-reads occur during the five business days after it. The City audits meters and may estimate usage after two failed access attempts; after two consecutive failures the location may be disconnected. The policy does not identify the AMI/AMR vendor or transmission interval.
