The Los Angeles County Waterworks Districts reads residential water meters monthly during the year. Billing follows the meter reading, and current rules and regulations are easily viewed on their webpage at DPW.LACounty.gov, as of August 2015.
The LACWD is a division of the LA County Department of Public Works and is responsible for providing a reliable water source for just under a quarter million people. Additionally, the LACWD practices and promotes environmentally sound practices while focusing on cost-efficient and sustainable water disbursement. The LACWD bills every owned property - residential or commercial - for water usage, but uses its discretion insofar as the number of meters on any given property.
