Request for Proposals

VWP Request for Proposals

Ventura Water, a division of the City, operates the Ventura Water Reclamation Facility (VWRF) which provides wastewater services to approximately 109,000 residents and businesses within the City limits and discharges tertiary treated effluent to the Santa Clara River Estuary.  The VWRF's current average annual influent flow is approximately 7.5 MGD.  The City utilizes a small portion of recycled water from the VWRF to provide irrigation to adjacent parks, medians, and golf courses. 

The City is interested in implementing membrane bioreactor treatment (MBR) as a part of the treatment scheme for the VWRF. MBR is a proven technology that provides: 

  1. robust biological treatment and nutrient removal, 
  2. robust pathogen removal, and 
  3. effective pretreatment ahead of reverse osmosis (“RO”) membranes. 

In conjunction, the City wishes to implement ultraviolet light disinfection (UV) as a replacement for chlorine disinfection.  Due to the need for the VWRF improvements and the fit with an anticipated downstream advanced water potable reuse facility, the City has decided to move forward with the development of an MBR/UV system to replace the current secondary, tertiary, and disinfection processes.

Proposal Submittal Deadline: May 2, 2023
