Despite Rain Delays, District Projects Remain Underway


Rainy days have significantly improved our water supply for the upcoming year. Despite the delays it has caused for District projects, the first phase of our Reservoir 2 Seismic Retrofit has been completed. The District understands the importance of continual investment in a water-resilient future and has invested $500,000 into this first phase of foundation reinforcement. The next phase of the seismic project is estimated to cost $4 million and is currently in the engineering phase. Steel banding on the exterior of the tank, recoating, and additional material upgrades are some of the essential components for this next stage.


The District works hard to maximize infrastructure investment value, and our forward planning team is diligently seeking grant funding to offset portions of the District's project costs. This is one of many projects that we have invested your water rates into to assure that the water at your tap today will be there tomorrow.


We are heavily focused on innovation for new water supplies. Investing in infrastructure helps us prepare for dry years, and this project, along with many other projects the District is currently working on, will help to maintain the water supply our community trusts us to deliver.

Take a look at your rates at work! 

District Expands Environmental Responsibility to its Investments


Excerpt from article on ESG Investments by Dan Muelrath, General Manager


On October 26, 2022, the District adopted its Environmental, Social, and Governance (ESG) Investment Policy that guides the actions on how the District invests its reserve funds. The ESG philosophy commits the District to invest in funds that contribute to a sustainable future for the environment, enrich the human experience, while minimizing risks and maximizing transparency of the company. Through the use of readily available ESG screening investment tools, the District established investment criteria and has been shifting all investments to satisfy the new ESG criteria.


While ESG is often used in the context of corporate investing, it has evolved into an important framework for public agency stakeholders (e.g., rate payers, community members, employees, municipal bond investors, rating agencies) as well. For Diablo Water District, the “why bother?” with ESG was simple.


Being uniquely located in the heart of the Sacramento/San Joaquin Delta, the District is on the leading edge of climate change effects. Impacts to the District, its customers, and water supply include changes in salinity, increased flood risk, and increased drought impacts. These impacts have led the District to shift from solely focusing on single and multi-year droughts to addressing the larger issue of climate change.



Although widely recognized as important factors to consider, ESG initiatives can be difficult to implement and measure, and can therefore result in disingenuous efforts. In the era of greenwashing projects to appease political interest, Diablo Water District has taken a refreshing approach regarding ESG policies: to create actionable regulations that will be implemented and have measurable results.

District Repairs


The District has been hard at work this first quarter of the year in planned repairs and quickly responding to leaks. Failing to invest in our water mains and service lines is not an option as it would negatively impact water supply reliability and general safety of our water system. The District is proud of our industry-leading 100-year replacement cycle and continues to plan for investments and improvements to sustainably manage your water supply for today and for the future.
