Wastewater and sewer calculation
Vallecitos bills sewer separately from potable water. The 2026 rate schedule includes a residential sewer monthly service-charge line and states that there was no sewer-rate increase in the January 2026 action; the reviewed public schedule does not expose a simple winter-average formula. Irrigation meters are separately tracked and generally do not generate wastewater treatment charges because irrigation water does not enter the sanitary sewer.
Meter and infrastructure notes
Vallecitos converted almost all meters to Automated Meter Reading. Electronic MXU/radio devices are read by a drive-by reader once per month on a location-dependent schedule; most meters are read electronically, and the District provides an interactive cycle/schedule lookup.
