Santa Cruz relies entirely on local water sources—primarily the San Lorenzo River, North Coast creeks, and underground aquifers. Unlike many other California cities, we don’t import water, making conservation and smart water management essential. While our community has a strong history of water conservation, climate change, drought cycles, and aging infrastructure are creating new challenges. To ensure a reliable water supply for the future, local water agencies are investing in major improvements.
Key Water Projects in Santa Cruz County
Several major projects are underway to strengthen and modernize our local water system:
Scotts Valley Intertie – This new pipeline will connect Santa Cruz and Scotts Valley water systems, allowing the two districts to share water when needed. This is especially important during drought years, helping ensure a steady supply for both areas. Expected completion: 2026.
Graham Hill Water Treatment Plant Upgrades – This plant, which treats most of the city’s drinking water, is undergoing major renovations to improve efficiency, increase wildfire protection, and make it more earthquake-resistant. Completion is expected by 2027.
Newell Creek Pipeline Replacement – The pipeline that carries water from Loch Lomond Reservoir is being replaced to reduce leaks and prevent breaks. This is one of the most critical projects for long-term water reliability. Estimated completion: 2025.
Beltz Wells Groundwater Recharge – Wells in Live Oak will be upgraded to help replenish underground water supplies, protecting against seawater intrusion and ensuring a stable water source for coastal communities.
What to Expect During Construction
These projects require major infrastructure work, which means homeowners may notice temporary road closures, construction noise, and potential service disruptions in certain areas. Water agencies are working to minimize impacts, but it’s good to stay updated on construction schedules and any potential changes to water use guidelines in your neighborhood.
Cost and Impact on Homeowners
The total cost of these projects is estimated to be over $200 million, funded through a mix of state grants, local water rates, and bonds. While much of the funding comes from existing resources, homeowners may see small increases in water rates over time to help cover costs. Investing in water-efficient appliances, drought-tolerant landscaping, and rainwater collection systems can help offset potential rate hikes while also contributing to long-term sustainability.
Looking Ahead
A secure and well-managed water supply is essential for maintaining property values and quality of life in Santa Cruz County. These improvements will help ensure reliable water access for years to come, even as our region faces ongoing drought challenges. Read the full article here by Santa Cruz Local
