SUMMARY: Staff has prepared a draft Water Production Summary Report
for Water Distribution Systems (WDSs) within the Monterey Peninsula Water
Management District (District) for Water Year 2007 (WY 2007). WY 2007 covers the 12-month period from
October 1, 2006 through September 30, 2007.
Preliminary computations indicate that 15,310 acre-feet (AF) of water
were produced by the 70 recognized WDSs in the District during WY 2007. In general, recognized WDSs refer to systems
that either: (a) received a WDS permit, or (b) were confirmed as a
grandfathered pre-existing system. The
California American Water (CAW) main system, which is the largest WDS in the
District, accounted for 14,076 AF, or approximately 92% of the total production
reported by WDSs in WY 2007.
RECOMMENDATION: This
report is for informational purposes only.
The Board should review the draft summary report and provide staff with
any comments or questions. Staff will
complete and file the final report, incorporating any late revisions, if this
item is approved with the Consent Calendar.
BACKGROUND: All owners and operators of WDSs within the District are required to annually submit water production information to the District. In 1980, District Ordinance No. 1 defined a WDS as works within the District used for the collection, storage, transmission, or distribution of water from the source of supply to the connection of a system providing water service to any connection including all water-gathering facilities and water-measuring devices. Therefore, all wells within the District are considered to be WDSs. However, until the adoption of Ordinance No. 96 in 2001, only multiple-parcel WDSs were required to obtain a permit from the District. Other refinements to the Rules and Regulations governing WDSs were added with the adoption of Ordinance No. 105 in 2002; Ordinance No. 106 in 2003; Ordinance No. 118 in 2005; and Ordinance No. 122 in 2006.
One new single-parcel systems WDS (i.e., Larson) and two new multiple-parcel WDSs (i.e., Head and Sena Trust) were established during WY 2007. In WY 2005, the Cañada Woods Alluvial, Cañada Woods Upland and Monterra Ranch WDSs were merged into the Cañada Woods Water Company WDS, although they are reported separately here to facilitate comparisons from one year to another.
Each WDS must report the amount of water produced and delivered, in addition to the number of existing and new connections served during the reporting period. The information for WY 2007 is summarized in Exhibit 14-A. The WDSs shown are grouped by source area. This information is also incorporated into the District-Wide Water Production Summary Report, presented as Item 15 of the Consent Calendar of this packet. For comparative purposes, the Annual Water Distribution System Production Summary Report for WY 2006 is provided as Exhibit 14-B.
Production figures for three WDSs -- Bishop, Ryan Ranch, and Hidden Hills Units -- are reported separately from the CAW main system, although CAW owns and operates each of these satellite units. The Ryan Ranch Unit was acquired and annexed into the CAW system in November 1989. The Hidden Hills Unit, which formerly reported as the Carmel Valley Mutual Water Company, was acquired and annexed into the CAW system in 1993. The Bishop Unit, which has been operated by CAW since September 1996, was acquired and annexed into the CAW system in July 1999. Although water production and delivery values for the Bishop, Hidden Hills and Ryan Ranch Units are reported separately from the values for CAW’s main system in this report, they are included in CAW’s total production in the District-wide Production Summary Report (Exhibit 15-A) as “CAW Wells Outside the Water Resources System”. In WY 2007, no water was produced from wells of the former Water West WDS, which was acquired and annexed into the CAW service area in 1989 and integrated into CAW’s main system in 1993. Water delivered to the former Water West WDS is incorporated into CAW's main system delivery total in this report and in Exhibit 15-A of the District-wide Production Summary Report. The former Rancho Fiesta WDS is also included as part of the CAW main system, because all water delivered to customers within the former service area of this system was produced from sources that serve CAW’s main system and the Rancho Fiesta production wells have been inactive for more than 10 years. For WY 2006 and WY 2007, all deliveries and connections to Rancho Fiesta customers were incorporated into totals for the CAW main system.
The production shown for Monterra Ranch includes water produced from wells that was sent to the system’s reverse osmosis (RO) desalination plant and non-potable water that was used for other purposes. For WY 2007, the reported percentage of unaccounted water at Monterra Ranch represents a comparison of the amount of RO plant and brine production (48.98 + 10.06 AF) minus metered consumption and brine production (44.89 + 10.06 AF) divided by RO plant and brine production (48.98 + 10.06 AF). This percentage does not include the amount of non-potable water produced by wells that was not sent to the plant (36.53 AF).
District-wide - Total WDS production within the District for WY 2007 was 15,310 AF. Of this total, the CAW main system (i.e., not including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for 92% of the water produced by WDSs within the District. The other 69 systems (i.e., including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for the remaining eight percent of production. Total WDS production for WY 2007 is 123 AF (0.8%) less than the production reported for WY 2006. During WY 2007, CAW’s main system production decreased by 143 AF (1.0%), while reported non CAW WDS production increased by 20 AF (1.6%), relative to production in WY 2006.
