State Small Water Systems
The Water System Program provides for the oversight of Public Water
Systems in the category of State Small Water Systems (SSWS). A SSWS is
defined as "a system for the provision of piped water to the public
for human consumption that serves at least five (5), but not more than
fourteen (14) service connections and does not regularly serve drinking
water to more than an average of 25 individuals daily for more than 60
days out of the year."
The program consists of the issuance of operational permits, routine
water system inspections, evaluation of water quality monitoring data,
and follow-up compliance activities.
Please note: Public water systems providing
water to 15 or more service connection, or regularly serving at least
25 individuals daily at least 60 days out of the year, are under the
jurisdiction of the State of California, Department of Health Services, Office of Drinking Water,
50 D Street, Suite 200, Santa Rosa, CA 95404-4752, Phone (707) 576-2145.
Transient-Noncommunity Water System Requirements
- A chemical analysis shall be conducted for the required constituents,
at the frequency established in the Safe Drinking Water Act (see Source Chemical and Bacteriological
Monitoring Requirements). As laboratory costs and procedures may
vary it is recommend that you review the monitoring requirements list
with your laboratory of choice. NOTE - If the water source has been
previously monitored for a listed chemical constituent, additional
monitoring of that constituent may not be required. A copy of any existing
chemical analysis data must be submitted in order to verify compliance
with the requirements.
- Bacteriological samples shall be taken each calendar quarter (3 months)
during which time the facility is open for business.
- All bacteriological sampling results shall be reported to the Sonoma
County Department of Health Services. Sampling results shall be submitted
no later than the 10th day of the month following collection.
- Should a bacteriological analysis indicate coliform organisms present,
you as the water supplier must take whatever corrective actions necessary
to eliminate the contamination problem, and assure the delivery of
a safe water supply. Corrective actions shall consist of, but not necessarily
be limited to: reviewing system operations; correction of any noted
defects; system disinfection if necessary, followed by bacteriological
sampling until such time as the contamination problem is corrected.
Note: Correction shall be demonstrated by bacteriological sampling
for two consecutive days, one sample each day, indicating no contamination.
All follow up sampling results must be reported to the Sonoma County
Department of Health Services.
- Additional monitoring requirements and other corrective actions may
be required by the Health Officer on a case by case basis, as conditions
warrant.
Should you have any questions concerning the above requirements, or
would like clarification of any of the regulations regarding the operation
of your water system, please call (707) 565-6565.
