Bill	Drinking water: consolidation and extension of service: domestic wells.	(1) Existing law, the California Safe Drinking Water Act, provides for the operation of public water systems and imposes on the State Water Resources Control Board various responsibilities and duties. The act authorizes the state board to order consolidation with, or extension of service from, a receiving water system, as defined, if a public water system or state small water system serving a disadvantaged community consistently fails to provide an adequate supply of safe drinking water or if a disadvantaged community is reliant on a domestic well that consistently fails to provide an adequate supply of safe drinking water. The act requires the state board, before ordering consolidation or extension of service, to, among other things, obtain written consent from any domestic well owner for consolidation or extension of service. The act makes any domestic well owner within the consolidation or extended service area that does not provide written consent ineligible, until consent is provided, for water-related grant funding, as specified. The act also requires the state board, before ordering consolidation or extension of service, to make a finding that consolidation of the receiving water system and subsumed water system or extension of service to the subsumed water system is appropriate and technically and economically feasible. The act defines "subsumed water system" for these purposes as the public water system, state small water system, or affected residences consolidated into or receiving service from the receiving water system.	us/states/ca	California Legislature	20192020	AB 508	California AB 508 (20192020)	bill	Drinking water: consolidation and extension of service: domestic wells.	enacted	Chu	11	36	8	2019-02-13	2019-09-27	openstates	ocd-bill/eb781f01-180f-441a-ae2e-ed43c877f1a4	http://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201920200AB508	3589df3fab04b105227b89a881b1b8bf454adc9da0a1e0ce0135eb2d84a5bc98	2026-07-01	https://data.openstates.org/daily/2026-07-01/public.pgdump	2026-07-06	reported	legislation bill us-ca

The act requires the state board, before ordering consolidation or extension of service, to, among other things, obtain written consent from any domestic well owner for consolidation or extension of service. The act makes any domestic well owner within the consolidation or extended service area that does not provide written consent ineligible, until consent is provided, for water-related grant funding, as specified. The act also requires the state board, before ordering consolidation or extension of service, to make a finding that consolidation of the receiving water system and subsumed water system or extension of service to the subsumed water system is appropriate and technically and economically feasible. The act defines "subsumed water system" for these purposes as the public water system, state small water system, or affected residences consolidated into or receiving service from the receiving water system.
