New Environmental Regulations Require Higher Levels of Wastewater Treatment

In response to the decline of the San Joaquin-Sacramento Delta ecosystem and concerns over ammonia, nitrates and pathogens, a series of tough new water quality requirements were imposed on us by the State of California through our discharge permit. Significant upgrades to our wastewater treatment plant must be completed by 2021–2023. These upgrades, known as the EchoWater Project, are expected to cost about $1.7 billion to build and approximately $50 million in additional yearly operations and maintenance costs. 

While funding the EchoWater Project has required several years of gradual rate increases, residential rates will now remain steady at the current level.
