WATER MANAGEMENT

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. 
Consumer conservation efforts are performing better than anticipated, conserving more water and preserving existing supplies.
Read the full WEAP Report here.

CMWD has been pursuing various capital improvements that will bring access to more supply and capacity district-wide.

WATER PROJECTS

 

Ojai Well Field Rehabilitation

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.

Current Phase:

Design/Construction

Begin: 2017

End:2020

Supply Enhancement (AFY):

200 - 500

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.

Current Phase:

Planning/ Preliminary Design

Begin: 2017

End:2023

Supply Enhancement (AFY):

1000-3000

Ventura-Santa Barbara Counties Interconnection

This project includes construction of a pipeline and pump station between Casitas MWD and Carpinteria Valley Water District. This intertie would allow each agency to provide water to the other during an emergency and provide Casitas with a means of accessing its State Water Project allocation using excess capacity in the South Coast Conduit pipeline in Santa Barbara County.

 

Casitas recently retained consultants to perform preliminary design and environmental/permitting services to support grant applications through the California Office of Emergency Services (CalOES) and Federal Emergency Management Agency (FEMA).

Current Phase:

Planning/ Preliminary Design

Begin: 2019

End:2022

Supply Enhancement (AFY):

2000

Matilija Formation Deep Wells

This project includes the construction of one or more deep water wells in the Matilija Formation. The District is investigating both horizontal and vertical wells in the vicinity of the Robles Diversion Facility. Water would be extracted under pressure and either treated or discharged to the Robles Canal for delivery to Lake Casitas. The project’s operational parameters will be determined through the CEQA* process and is currently proposed to only be used during times of drought or other emergency. Casitas is convening a Technical Advisory Committee to review background documents and feasibility of this project; findings and recommendations are expected in June 2019.

Horizontal Bore (HOBO). The HOBO project is awaiting approval from the US Forest Service for the installation of stream monitoring gauges to assess the viability of the project.

 

Robles Deep Vertical Bore (RDVB). The District is in the process of completing an Initial Study/Mitigated Negative Declaration to comply with CEQA for a test well. Plans and specifications are being prepared for construction of the test well, which would be monitored for several years to gather information on water quality and quantity.

Current Phase:

Planning/ Permitting/ Exploratory

 Design

Begin: 2016

End:2022

Supply Enhancement (AFY):

2000-8000

Ojai Desalter Project

This project involves a new deep well and the installation of treatment equipment to remove high levels of salt. Equipment typically used includes a membrane treatment plant and a pipeline to the local wastewater system to dispose of brine concentrate from the treatment process.

 

Currently, Casitas is not pursuing this project as the focus is on rehabilitating or replacing existing wells.

Current Phase:

Inactive

Begin: 2021

End:2023

Supply Enhancement (AFY):

500 - 1000
