            FROM:           Michael Niccum, District Engineer

 

            SUBJECT:      Utilities Operations and Maintenance

                                    Report for 7/20/06 to 8/17/06

 _________________________________________________________________________

 

1.           SUMMARY  OF  MAINTENANCE  ACTIVITY:

 

The maintenance department painted the interior floors, valves and piping in pump stations: P-7 (18th Fairway of Pebble Beach Golf Links), P-5 (Easement below Sunset Lane) and P-4 (Highway 68 and Crest Road Cul-de-sac).  The maintenance department coordinated a potable (fresh) water flush to the golf courses from August 11-16, replaced the brakes on PB-2 (vacuum truck), cycled recycled water pipeline valves, cleaned the surge tank at pump station P-5 and coordinated 3 residential dye tests.  In support of the Forest Lake Reservoir Project, the maintenance department calibrated the chlorine residual analyzer and deployable multi-parameter water quality probe at the reservoir outlet structure, inventoried new equipment spare parts and coordinated grass / weed abatement around Lookout Road. 

 

2.         WASTEWATER  FLOW  MEASUREMENTS:

 

An average daily wastewater flow of 483,000 gallons per day (gpd) was measured at the PBCSD Carmel gate flow metering station in July, which represents 26 % of the total flow of 1,826,000 gpd measured at the CAWD treatment plant.  The measured PBCSD flow is   9 % below the five-year average of 531,000 gpd for July and the CAWD total flow is 4 % above the five-year average of 1,761,000 gpd for July.  A chart showing the quantity of PBCSD wastewater flow recorded during the month of July and a graph showing average daily wastewater flows from PBCSD and the CAWD treatment plant for the past twelve months as well as the five-year average for each month is attached.

 

3.         RECYCLED  WATER  USE:

 

Total irrigation water demand for the 2005-06 water year (October 1 to September 30) to date is 602 acre-feet including 498 acre-feet or 83 % of recycled water.  Total demand for the water year is 7 % below the 11-year average usage of 650 acre-feet for this point in the water year.  The July flushing cycle used 25 acre-feet of potable water.  Approximately 98 acre-feet of potable water have been used in flushing cycles during the current water year, which accounts for 95 % of the total potable water use of 104 acre-feet. 

 

Two attached charts show the total water and potable water usage recorded on a daily basis for July and August to date.  Two additional charts and a graph summarize total, recycled and potable water usage on a monthly basis for the 2005-06 water year to date and for the previous eleven water years.

5.         UNDERGROUND  SERVICE  ALERT  CALLS:

 

During this period, the maintenance crew marked sewer or recycled water lines at the following locations in response to underground service alert (USA) calls.  Contractors or other utilities are required to contact the USA system prior to performing construction activities that involve trenching or other underground work.  The system is designed to provide underground utility locations to the contractor so that the construction work can be completed without damaging the existing utility lines.  The District identifies the location of wastewater lines with green paint and recycled water lines with purple paint.
