Construction will begin in August for two pipeline projects in Ojai – N. Ventura Street between Ojai Avenue and Summer Street, and Sunset Place between Mountain View Avenue and Grandview Avenue. Pipelines, fire hydrants, valves, and service lines will be replaced. We will keep affected residents notified in advance of any system shutdowns. We appreciate your patience as we upgrade the water system in this area. Please contact us at 805.649.2251 if you have any questions.

Water Supply

Updated: June 11, 2019

*Most recent Ojai Basin Pumping: 4,514.98 AF (per OBGMA)

AFY = Acre Feet/Year.  1 acre-foot is 325,851 Gallons


Casitas Municipal Water District manages water supply primarily through the Water Efficiency and Allocation Program, or WEAP. 
The Program ensures allocations of water and conservation targets are in line with drought conditions.

Water Projects
Ojai Well Field Rehabilitation
Casitas Ventura State Water Project Interconnection
Ventura Santa Barbara Counties Interconnection
Matilija Formation Deep Wells
Ojai Desalter Project


This project includes the rehabilitation and replacement of several drinking water wells operated by CMWD in the Ojai Groundwater Basin. The goal is to bring the wells back to their original production capacity by improving and enhancing infrastructure.


The District awarded a contract to rehabilitate one well in March 2019, which is expected to be completed by the end of April 2019. An additional well is scheduled for rehabilitation after the high summer demand period. The budget for fiscal year 2019-2020 will also include funding for a replacement well, which is expected to be online prior to summer of 2020.

Casitas- Ventura State Water Project Interconnection

This project involves the construction of a pipeline to connect the City of Ventura’s water system to the Calleguas Municipal Water District’s water system. This shared connection will allow the City, United Water Conservation District, and Casitas MWD to access their individual State Water Project allocations through Calleguas via the Metropolitan Water District.


To this end, Casitas has shared in the cost of the City of Ventura’s State Water Interconnection Alignment Study and Environmental Impact Report.


Casitas also recently retained an engineering firm to prepare a Preliminary Design Report for the facilities to bring water from the west side of Ventura to connect to Casitas’ transmission pipelines near Foster Park and extend to Lake Casitas. The report is expected to be complete by the end of 2019.

I am a concerned resident — what is the status of Casitas Municipal Water District’s water supply?
How much rainfall do we need to fill Lake Casitas?
When can we stop conserving?
How is Casitas Municipal Water District planning for these droughts?
What are the drought stages?
What are the current residential watering restrictions at Stage 3?
Does the District currently have a target for customers to reduce water use?
I hear from my neighbor that it is inevitable that Lake Casitas will run dry — what are we doing to preserve and enhance water resources in order to avoid this outcome?
