EXECUTIVE OFFICER SUMMARY REPORT

MEETING DATE: August 21, 2002 (Richard Condit)

ITEM: 3B

SUBJECT: UNION OF AMERICAN HEBREW CONGREGATIONS (CAMP SWIG)

SARATOGA, SANTA CLARA COUNTY – Adoption of Revised

Waste Discharge Requirements

CHRONOLOGY: The Board adopted Waste Discharge Requirements in 1978, an Amendment in 1979 and an update in 1987.

DISCUSSION: Union of American Hebrew Congregations (hereinafter Camp Swig) is constructing a natural passive wastewater treatment and disposal system to serve Camp Swig, a retreat and conference center and summer youth camp. Camp Swig is located west of Saratoga on Saratoga Creek, at the headwaters of Stevens Creek, a tributary of San Francisco Bay (See location map in Appendix A).

Camp Swig is a very old facility that is being rebuilt and upgraded. The project will involve demolishing and rebuilding 39 buildings, including camper housing, staff housing, some storage facilities, bathrooms and art studios. The new Camp Swig facilities will serve 220 summer campers and 75 employees and will be ready for use in the spring of 2003.

A natural passive wastewater treatment and disposal system will be constructed to use subsurface irrigation for disposal of highly treated wastewater. Primary treatment will be provided by a 16,000-gallon septic tank. Secondary treatment will be attained in a re-circulating sand filter with a 16,000-gallon re-circulating tank. The sand filter will be designed so that portions of it can be turned off during low flow periods. The final effluent will be disinfected through chlorine dosage and stored in a 48,000-gallon tank before being distributed through the subsurface irrigation system.

The effluent quality will meet the Department of Health Service’s reuse/reclamation standards for subsurface irrigation and will produce an effluent with less than 20 mg/l of total inorganic nitrogen (ammonia, nitrite, and nitrate nitrogen) and less than 10 mg/l of 5-day Biological Oxygen Demand (BOD5) and Total Suspended Solids (TSS). Total Coliform will meet a 23 MPN standard, as a safeguard to personnel during maintenance of the irrigation system. The subsurface irrigation system will be designed to deliver only evapo-transpiration water requirements and nitrogen needs of a new landscaping system that will be designed to utilize the final effluent. There will be minimal liquid effluent percolation below the lower boundary of the A horizon

of the subsurface soils.
