Frequently Asked Questions
- What is the VenturaWaterPure Program?
VenturaWaterPure is a purified recycled water, also known as potable reuse, program that will recover, treat, and reuse water that is currently discharged into the Santa Clara River Estuary.
This program will divert treated water from Ventura’s wastewater treatment facility to a new Advanced Water Purification Facility, where the water will be treated to drinking water standards and then injected into a local groundwater basin for storage, and later extracted and delivered to customers.
Advanced purification involves multiple treatment processes. This treatment begins at the existing Ventura Water Reclamation Facility (VWRF), which will be upgraded with Membrane Bioreactors and an Ultraviolet (UV) Light disinfection system. This treated water will then be sent to the new Advanced Water Purification Facility, which will further treat water using Reverse Osmosis (RO), additional Ultraviolet Light, and Advanced Oxidation (UV / AOP). This proven approach, known as potable reuse, is currently used throughout California, other States, and internationally and is regulated by the State Water Resources Control Board’s Division of Drinking Water.
- How does the program work?
The VenturaWaterPure Program includes a network of infrastructure designed to recover, treat and reuse water that was previously discharged into the Santa Clara River Estuary.
STEP 1. Currently, wastewater from the City of Ventura is sent to the Ventura Water Reclamation Facility (VWRF), where it’s treated and cleaned before being discharged into the Santa Clara River Estuary. The VWRF is being upgraded with a Membrane Bioreactor and Ultraviolet (UV) Light disinfection, which will provide a higher quality of water than currently produced.
STEP 2. Water from the VWRF is sent to a new Advanced Water Purification Facility (AWPF) for reuse. Using a scientifically proven process, the AWPF will treat water to drinking-water standards, creating a reliable, locally controlled, and high-quality water source.
STEP 3. The purified water will then be injected into a local groundwater basin and later distributed to Ventura Water customers.
The concentrate generated during the treatment process will be sent to an ocean outfall for disposal.
- What are the benefits of VenturaWaterPure?
The VenturaWaterPure program will allow Ventura to meet legal requirements, improve water quality, and secure a new local source of drinking water that is drought resilient. Program benefits include:
- Drought Resistant. Creates a drought-resistant, reliable water supply that isn’t dependent on rain.
- High-Quality. Provides a high-quality drinking water supply that meets and exceeds water quality standards.
- Environmentally Protective. Meets regulatory requirements by reducing water discharge into the estuary, creating a natural environment that can support endangered species.
- How does VenturaWaterPure help with Ventura’s water supply?
VenturaWaterPure will produce approximately 3,600 AFY of new locally controlled water supply by 2027 and up to 5,400 AFY by 2032.
- What are the program components?
- Membrane Bioreactor/UV: New treatment at the VWRF that provides high-quality water for the new AWPF, existing reuse customers, and discharges to the Santa Clara River Estuary.
- Advanced Water Purification Facility (AWPF): a new facility to treat wastewater from the Ventura Water Reclamation Facility (VWRF) to drinking water standards.
- Land: land required for the AWPF facility and groundwater injection sites.
- Injection/Extraction Wells: groundwater wells for injection and extraction of purified water.
- Pipelines: to convey treated water between the VWRF and AWPF and from the AWPF to the injection wells.
- Pump Stations: required to transport water at multiple steps in the treatment process.
- Ocean Outfall: new infrastructure needed to discharge concentrate generated
- Why is a new ocean outfall needed?
An outfall is needed to discharge concentrate generated by the new Advanced Water Purification Facility (AWPF), as part of the VenturaWaterPure, potable reuse project. Additionally, the outfall will support wet weather flows that exceed the AWPF capacity and in event of an AWPF shutdown.
- Will the outfall have negative impacts to the environment or wildlife?
The outfall will be designed to mitigate any potential impacts to the environment and wildlife. The impacts were evaluated in the Ventura Water Supply Projects Environment Impact Report, and the City will comply with all identified mitigation measures.
- When will construction of the outfall take place?
The ocean outfall and pipeline installation is expected to take approximately 11 months to complete. The project has two (2) segments:
- Offshore segment: There will be two (2) horizontal directional drill locations. One at Marina Park and one near the Ventura Port District across the Harbor. Work at Marina Park is expected to be completed by May 2024.
- Onshore segment: The pipeline installation will be within Anchors Way, Schooner Drive, and Harbor Boulevard to the existing Ventura Water Reclamation Facility. This work is expected to be completed by July 2024.
- How was the location of the outfall determined?
A very thorough evaluation took place prior to selecting the Marina Park location, including a study to evaluate the use of existing outfalls that were previously abandoned. Ultimately Marina Park was the only location that avoided subsurface obstructions and fault lines, provided enough construction workspace, and would increase the overall protection for the pipelines offshore. Additional information on that evaluation is discussed in the Ventura Water Supply Projects Environmental Impact Report.
- What are the impacts to Marina Park?
A portion of Marina Park will be closed for drilling equipment and pipeline construction. The drilling equipment will be enclosed in a 24-foot sound wall perimeter for potential noise mitigation. In addition, a portion of the parking lot will be closed for contractor staging, pipe storage, and assembly.
Access to the walking paths will be maintained as well as access to the Leo Robbins Sailing Center.
After construction is completed, the park will be restored to its pre-construction condition. Expected completion date is by Memorial Day 2024.
