Project Scope and Method
The California Urban Water Conservation Council has identified the replacement of liquid ring vacuum pumps with dry vacuum systems as a Potential Best Management Practice (PBMP). This investigation was undertaken to assess the potential viability of dry vacuum pump systems as a Best Management Practice (BMP) for urban water purveyors in California.
The assessment included:
- A literature review to ascertain the latest technology in the market, its costs, benefits, and water
- Interviews with representatives of relevant industry associations, and other regulatory bodies with
jurisdiction with respect to this technology
- Interviews with key staff of water agencies that have or have had programs involving dry vacuum pump systems
- Evaluation of potential water savings and cost-effectiveness of different types of dry vacuum systems
- Development of recommendations on the advisability of upgrading from a PBMP to a BMP.
