ISSUE: Central Contra Costa Sanitary District's (CCCSD's) 2009 Recycled Water
Quality and Distribution Annual Report has been prepared for submission to the
California Regional Water Quality Control Board (RWQCB), San Francisco Bay
Section. This annual report is attached for Board of Directors' information and
acceptance.
RECOMMENDATION: Accept the 2009 Recycled Water Quality and Distribution
Annual Report.
FINANCIAL IMPACTS: None
ALTERNATIVES/CONSIDERATIONS: Reject the 2009 Recycled Water Quality and
Distribution Annual Report, which is not recommended.
BACKGROUND:
Recycled water remained in compliance with applicable tertiary recycled water quality
standards, except for dissolved oxygen (DO) of less than 1.0 mg/L on October 18,
2009. Excessive microbial growth in the filter media is believed to be the cause of this
episodic low DO. However, we believe that the DO at the points of application of
recycled water most likely was well above 1.0 mg/L because of turbulence and mixing
by the pumps and in the delivery pipes downstream of the sample point.
Significant accomplishments for this years' Recycled Water Program are described in
the attached 2009 Recycled Water Quality and Distribution Annual Report. The report
was reviewed by-the Recycled Water Committee at their February 24, 2010, meeting
and was recommended for Board acceptance.
RECOMMENDED BOARD ACTION: Accept the 2009 Recycled Water Quality and
Distribution Annual Report.
