This paper evaluates the feasibility of a potential Pacific Grove Storm Water Recycling Facility (SRF)
that would divert storm water, provide treatment, and deliver recycled water to several irrigation sites in
the City. The runoff analysis shows that there is sufficient runoff from the Congress storm drain watershed even
in a typical hydrologic average year to meet the City's irrigation demands. The runoff must be retained
during the fall-winter wet period so that it is available for recycling during the spring-summer irrigation
season. A new 15 million gallon concrete reservoir is proposed to be constructed at the California
American Water Company's David Avenue property. Supplemental irrigation of Washington Park appears to have an additional benefit of enhancing the
habitat of the famous Monarch Butterfly, which is restricted during drought periods.
The storm water contains several constituents that must be reduced or eliminated in order to meet
aesthetics and comply with regulatory requirements, particularly the California (CA) Department of
Public Health Title 22 Regulations for irrigation with non-potable water. A treatment plant needs to be
constructed for this purpose, and should include the following processes: trash and debris
separator; constructed wetlands; microfiltration (MF); ultraviolet light (UV); and, liquid
hypochlorite for disinfection. The conclusion of the paper is that the SRF Project is feasible, and would result in the
following benefits:
reduction of pollution to the Monterey Bay Marine Sanctuary;
development of a new local water supply;
compliance with Monterey Bay Cease and Desist Order through project implementation; and, enhancement of the critical Monarch Butterfly habitat. Includes tables, figures.
