How this utility’s billing works

The published water-rate framework is described as Meter-size and service-area tiered rate structure with a minimum charge, lifeline usage bands, usage charges per 1,000 gallons, and a Community Benefit breakdown. Effective June 22, 2026, rates are displayed differently but the City states the underlying rates are not changing; customer-assistance, conservation/energy-efficiency, and franchise-fee components appear separately.. Bills are generated monthly. the city utility bill combines electric, water, wastewater, garbage, and recycling where applicable; due dates depend on one of four billing cycles., and a typical residential cost reference is For an inside-city 5/8-to-3/4-inch meter using 5,000 gallons, the June 22, 2026 water schedule begins with a $30.19 minimum, a $0.06 customer-assistance component, $0.70 conservation/energy-efficiency component, and $1.81 franchise-fee component; the first 6,000 gallons are charged at $5.17 per 1,000 gallons under the displayed table. Water alone is therefore approximately $58.61 before sewer, electric, garbage, and other bill charges; actual rate presentation should be checked against the current bill.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.

Residential sewer rates are calculated from average water usage during winter months. Customers without enough usage history receive a flat 5,000-gallon basis. The Community Benefit charge also applies to water and wastewater services and funds assistance, conservation, and related programs.
Meter and infrastructure notes
Customer Connect exposes water usage and daily/monthly threshold alerts; San Marcos's 2026 portal procurement also identifies MeterSense in the utility-system integrations. The reviewed public pages do not state the universal local meter vendor or exact transmission interval.
