Year(s) Milestone
2019 District Transparency Certificate of Excellence - As in previous years, the CVWD received the District Transparency Certificate of Excellence from the Special District Leadership Foundation. Recipients of this award demonstrate their effort to promote transparency in the operations and governance of their district.
Meter Reading Technology Upgrade - The District completed the Automated Meter Reading Infrastructure (AMI) project. The District receives hourly meter reads reaching approximately 95% of the District’s meters. With the power of this data in hand, the District created the Water Watch Program (WWP). The WWP identifies continuous water flow (e.g. customer leaks) and proactively communicates with our customers to save the customer money and conserve this precious resource.

Nitrate Treatment Facility - The District substantially completed the construction of the Nitrate Treatment Facility using a progressive design-build delivery method. This project will improve the water quality of Well Field 3A and allow the District to produce a more significant amount of water from the Cucamonga Basin. The District successfully applied $2.5 million of grant funding to this critical project.
2018 By-division Election System – CVWD and many other public agencies throughout California have switched from an at-large to a by-division election system. After an extensive public process, the Board enacted a 5-division boundary map. Only those registered voters in each respective five divisions can vote during each election. View the by-division map here.

District of Distinction Award from Special District Leadership Foundation - CVWD received the 2-year “District of Distinction” accreditation by the Special District Leadership Foundation for its sound fiscal management policies and practices in district operations.
2016 Water Meter Upgrade - The District initiated the process of upgrading residents' water meters. The new meter upgrade will enable customers to access more detailed information about water usage, providing another tool to help use water efficiently.
Customer Assistance Program (CAP) – CVWD created this program to assist low-income customers with a nominal credit on their utility bill. Other customers do not subsidize the CAP; instead, the CVWD pledges a maximum of 65% of the District’s unrestricted cellular tower rental income. Customers must meet income eligibility guidelines as established each year the by California Public Utilities Commission.

Completion of construction at Lloyd W. Michael Water Treatment Plant - The Lloyd W. Michael Water Treatment Plant upgrades were completed in 2015, resulting in the District’s largest project since the original construction of the Treatment Plant in 1989. Changes to the federal Clean Drinking Water Act required the District to add a process for improved water quality treatment. The upgrades included the addition of a six-million-gallon reservoir for increased onsite storage. Total project costs were just over $40 million.

60th Anniversary - In March 1955, the Cucamonga County Water District held its first board meeting and began the task of searching for the water that is predominantly agricultural-driven region to thrive. Though the Cucamonga region looks very different than it did 60 years ago, the District continues to identify and secure the water necessary to provide for the region.

Governor Declares Drought Emergency - In May 2015, the CVWD Board of Directors adopted a resolution increasing water conservation requirements to a Stage 6: Severe Water Emergency requiring 35% conservation by all customers. Drought rates went into effect for the first time in CVWD history. The Board's action was taken in response to the State Water Resources Control Board's resolution adopting emergency regulations for water conservation by all cities and water agencies. Restrictions and drought rates were lifted one year later and CVWD customers conserved an average of 27% water.
2014 Arthur H. Bridge Upgrade - The Arthur H. Bridge Water Treatment Plant was constructed in 1997 to treat Cucamonga Canyon water. In 2010, winter storms caused significant damage to the facilities. In 2013, CVWD began to rehabilitate the Cucamonga Canyon intake facilities and replace the treatment technology at the Plant. The Bridge Plant reopened in June 2014 and can treat up to three million gallons per day of high-quality canyon water, helping CVWD become less reliant on imported water.
100th Recycled Water Customers - The District announced that its 100th recycled water customer came online in May 2014, helping the District to further secure a reliable water supply for customers. Recycled water is a valuable resource used in landscaping and in some commercial business processes. One of the main benefits of using recycled water is that it enables CVWD to reserve potable (drinking) water for inside homes and businesses, as well as for other human consumption purposes. These kinds of changes enable CVWD to preserve more water on a yearly basis, and more importantly during dry seasons.

$5 million grant received from Prop 50 funding used for UV disinfection facility- The District received $5 million in state funding through a Prop 50 grant for upgrades to the Lloyd W. Michael Water Treatment Plant. The Lloyd W. Michael Water Treatment Plant treats imported water that nearly 200,000 people use throughout the CVWD community. The Prop 50 grant will help fund the new UV disinfection facility, a process that uses ultraviolet light to treat the water.
2013 The District began work to rehabilitate the Cucamonga Canyon intake facilities and replace the existing membrane technology with pressure filtration at the Arthur H. Bridge Water Treatment Plant.  
2012 The District embarks on one of its largest construction projects in its history. The Lloyd W. Michael Water Treatment Plant undergoes a significant renovation to its treatment process to comply with recent changes to drinking water regulations set by the U.S. Environmental Protection Agency. In addition to the treatment process upgrade, CVWD will increase the reliability of its water system by increasing reservoir storage at the plant. 
2010 Winter storms washed out the District facilities at the Arthur H. Bridge Water Treatment Plant that captured water in the Cucamonga canyon which accounts for 10% of the CVWD's water supply.   
2004 The Cucamonga County Water District formally changes its name to the Cucamonga Valley Water District (CVWD), as a direct reflection of the community served by the District. 
2003 The District had completed construction of its new Operations Facility, located next to the administrative facility on Ashford Street. The building is 42,000 square feet and costs approximately $7.1 million.
2001 The District secures a valuable local water source when it finalizes the purchase of the Fontana Union Water Company stock, previously leased from Kaiser Ventures. Also this year, the District is honored as one of the "Top Companies to Work for in the Inland Empire."
2000 The District completed the construction of a new Administrative Facility, located at 10440 Ashford Street. The total cost of the new facility is approximately $6.3 million. The facility is about 26,700 square feet and houses all District office staff. A Dedication Ceremony took place and featured Congressman Joe Baca and California State Senator Nell Soto as speakers. 
The Arthur H. Bridge Microfiltration Treatment Plant, the District's third treatment facility, becomes operational in October. This plant has the capacity to treat 4 million gallons of water per day and uses a state-of-the-art microfiltration process, which is an ultra low-pressure membrane process, to remove impurities in the water.  
1993 The District is notified by the California Department of Health Services that the Cucamonga Canyon water source is subject to the Surface Water Filtration and Treatment Disinfection Rule. The District determines the canyon water is a reliable and good quality source and authorizes the construction of a third treatment facility to treat the water. 
1992 The District enters into a memorandum of understanding with Kaiser Resources to lease Fontana Union Mutual Water Company shares owned by Kaiser. This entitles the district to approximately 50% of the available usable water on an annual basis. 
1989 The District constructs its second treatment facility, the Lloyd Michael Water Treatment Plant, to treat water from the State Water Project. The plant has the capacity to treat 45 million gallons of water per day and can be expanded to treat 90 million gallons of water per day if needed. 
1980s New deep wells are constructed in both the Cucamonga Basin and the Chino Basin in order to meet the growing demand for water. 
1979 The District establishes a connection to the State Water Project pipeline. The Royer-Nesbit Water Treatment Plant, the District's first treatment facility, is constructed to treat water from the State Water Project in addition to local surface flows from Day Canyon and East Etiwanda Canyon. 
1963 The District's service area continues to expand and extend eastward to include Etiwanda and portions of the City of Fontana. The District obtains additional water supplies by developing the surface water sources in Deer Canyon and Cucamonga Canyon. 
1957 A water system development plan is adopted by the District and a subsequent bond issue in the amount of $3.7 million is approved by the voters of the District. This plan includes the acquisition of 14 private water companies and the development of additional water supplies and storage facilities. 
1956 Basic local water system construction is completed and becomes operational in September. 
1955 Voters approve a $1.2 million bond issue to construct the facilities needed for the community's new water district, the Cucamonga County Water District.
