Wastewater and sewer calculation
Cal Water bills the Palos Verdes potable-water charge. Sewer or wastewater charges are normally imposed separately by the City of Palos Verdes Estates, Rolling Hills, Rolling Hills Estates, Rancho Palos Verdes, Lomita, Los Angeles/San Pedro, or another serving sewer agency and are not governed by one Cal Water formula. The sewer agency may use actual water consumption, a winter average, a residential cap, or a fixed equivalent-unit charge. Customers should compare the water meter usage with the separate sewer bill and ask the serving agency for its current base, usage, winter-average, and adjustment rules.
Meter and infrastructure notes
The Palos Verdes system uses customer water meters and Cal Water's periodic billing reads. The district pages do not publish a fixed local AMI deployment percentage or route day; Cal Water company materials describe AMR/AMI pilots in selected districts but do not establish that every Palos Verdes account has an advanced meter. Customers should use the bill's read dates and current/previous reads, review usage history in the portal, and ask Cal Water to confirm the exact meter technology and leak-alert capability for the premise. SDWIS lists four active treated Metropolitan Water District connections through West Basin, with no active local treatment plant shown for this CWS.
