Wastewater and sewer calculation

The reviewed Cal Water materials do not publish a Livermore wastewater formula, winter-average method, or percentage tie-in. Sewer charges, if applicable, are billed or administered separately by the responsible local sewer agency or property arrangement; customers should use that agency's sewer account rules rather than infer wastewater charges from the Cal Water meter bill.
Meter and infrastructure notes
The Livermore system uses customer meters and Cal Water's billing process relies on periodic meter readings; the district page does not publish a fixed local AMI deployment percentage or route day. Cal Water's planning materials and company-wide information describe AMR/AMI pilots in several districts, but do not establish that every Livermore account has an advanced meter. Customers should use the bill's read dates, meter number, and current/previous reads; the portal provides usage history, while Cal Water can confirm the exact meter technology and leak-alert capability for an individual premise.
