The Tanglewood System is primarily supplied from local groundwater pumped through wells operated by Golden State Water, and has a connection to receive supplemental surface water from the Central Coast Water Authority.

Conservation

While the region has experienced increasing levels of precipitation since 2023, the rainfall did not sufficiently recharge local groundwater basins, the area’s primary water source. Until conditions improve, the Cypress Ridge and Nipomo water systems remain in Stage Two with mandatory restrictions while Santa Maria, Lake Marie, Sisquoc, and Tanglewood remain in Stage One.

Important Drought Notice:

Cypress Ridge and Nipomo customers are required to reduce water usage by 20% compared to 2020.

System	Reduction goal	Actual reduction *
Cypress Ridge	20%	-7%
Nipomo	20%	-8%

*Actual reduction (compared to 2020 usage)

Stage 1: Outdoor irrigation recommended no more than three days per week, before 8 AM or after 7 PM; even addresses on Sunday, Wednesday and Friday, odd addresses on Tuesday, Thursday and Saturday

Stage 2: Outdoor irrigation limited to two days per week, before 8 AM or after 7 PM; even addresses on Sunday and Wednesday, odd addresses on Tuesday and Saturday.

In order to achieve the mandatory reductions, the following Staged Mandatory Water Conservation and Rationing Plan has been filed for the local water system.

Rates

As a regulated utility, every three years Golden State Water’s rates are determined by the California Public Utilities Commission (CPUC) through a General Rate Case (GRC) to ensure customers receive a fair rate for reliable, quality water service. New rates allow for investments to avoid the costly and sometimes dangerous effects of deferring maintenance or delaying the replacement of aging infrastructure.

2023 General Rate Case (2025-27 Rates)

In January 2025, the California Public Utilities Commission (CPUC) adopted a General Rate Case for Golden State Water Company (Golden State Water) that includes local infrastructure investments and new water rates for 2025, 2026, and 2027. The new rates went into effect February 1, 2025.

These rates reflect Golden State Water’s long-term commitment to providing customers with high-quality water and reliable service by proactively investing in their community’s water supply and distribution systems. We never want customers to think twice about the quality of the water coming from their taps.
