Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly; Longmont mails utility bills every 30 days and rate schedules are monthly.
- Rate structure
- Monthly meter-size service charge plus increasing residential volume blocks. Effective January 1, 2026 inside city limits, a typical 5/8-inch meter is $11.91 monthly; water is $4.84 per 1,000 gallons for 0-5,000, $7.27 for 5,001-15,000, $9.69 for 15,001-35,000 and $13.08 over 35,000. Storm drainage is an additional $18.85 monthly residential fee.
- Residential cost reference
- Approximately $82-$100 per month for an inside-city 5/8-inch account using 5,000-7,000 gallons: $11.91 water base plus about $24-$39 water volume, $11.50 wastewater base plus about $39-$55 wastewater volume, and $18.85 storm drainage. The estimate excludes electric, solid waste and account-specific adjustments.
- Wastewater and sewer calculation
- Metered wastewater is a monthly $11.50 service charge plus $7.82 per 1,000 gallons; unmetered residential wastewater is $51.67 monthly. Longmont's wastewater calculation is based on metered water use rather than a published winter-average formula, with industrial pollutant surcharges possible for qualifying commercial users.
- Meter reading
- Longmont bills monthly by meter size and gallons used; customers can view water-usage history through MyUtilityAccount. The reviewed current pages do not identify AMI/AMR hardware, transmission interval or universal route-reading schedule.
- New-account deposit
- Residential deposits are retained for one year and then reviewed; if payments were timely, the deposit and accrued interest are credited. If residential service ends earlier and the account is paid in full, the deposit and interest are refunded by check. Businesses pay a one-month or three-month estimated-usage deposit, with a minimum commercial deposit of $200.
- Activation or transfer fee
- Residential owners/purchasers can connect online or by phone, with at least two business days by phone or three online. The reviewed current connection pages do not publish a universal residential activation fee; commercial connection requires the applicable estimated-usage deposit and service agreement.
