SUMMARY: Staff has prepared the draft Water Production Summary Report
for Water Distribution Systems (WDSs) within the Monterey Peninsula Water
Management District (District) for Water Year (WY) 2009. WY 2009 covers the 12-month period from
October 1, 2008 through September 30, 2009.
Preliminary computations indicate that 14,398 acre-feet (AF) of water
were produced by the 98 recognized WDSs in the District during WY 2009. In general, recognized WDSs refer to systems
that either: (a) have received a WDS permit, or (b) have been confirmed as a
pre-existing system prior to District rules that expanded WDS permitting
requirements. The California American
Water (CAW) main system, which is the largest WDS in the District, accounted
for 13,099 AF, or approximately 91% of the total production reported by WDSs in
WY 2009.
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.
Fifteen new single-parcel WDSs (i.e., The Rusek, Oh Well/Poole, Bellamy, Sleepy Hollow 16/Collins, Sleepy Hollow 17/Collins, Stemple, Dunnion, White, Mayl, Lauch, Thorp, Dale, Roddick, Outzen, and Carrol/Rancho U Water Distribution Systems) were established in WY 2009, along with one new multiple-parcel systems (Long Ridge SLCSD). It is also noted that 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 where required the amount of water delivered, in addition to the number of existing and new connections served during the reporting period. The information for WY 2009 is summarized in Exhibit 11-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 12 of the Consent Calendar of this packet. For comparative purposes, the Annual WDS Production Summary Report for WY 2008 is provided as Exhibit 11-B. Note that the version of the Annual WDS Production Summary Report for WY 2008 presented here has been revised since it was originally presented to the Board on April 20, 2009, based on information received since that time.
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 smaller systems. 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 12-A) as “CAW Wells Outside the Water Resources System”. In WY 2009, 123.57 AF of water were produced from wells in 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 12-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 2008 and WY 2009, all deliveries and connections to Rancho Fiesta customers were incorporated into totals for the CAW main system.
The production shown in Exhibit 11-A for Monterra Ranch includes water produced from wells that was sent to the system’s reverse osmosis (RO) desalination plant and un-treated water that was produced for non-potable purposes. For WY 2009, the reported percentage of unaccounted water for Monterra Ranch represents a comparison of the amount of RO plant and brine production (53.72 + 14.02 AF) minus metered consumption and brine production (50.62 + 14.02 AF) divided by RO plant and brine production (53.72 + 14.02 AF). This percentage does not include the amount of non-potable water produced by wells that was not sent to the plant (2.31 AF).
District-wide - Total WDS production within the District for WY 2009 was 14,398 AF. Of this total, the CAW main system (i.e., not including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for 91% of the water produced by WDSs within the District. The other 97 systems (i.e., including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for the remaining nine percent of production. Total WDS production for WY 2009 is 1,245 AF (8.0%) less than the production reported for WY 2008. During WY 2009, CAW’s main system production decreased by 1,126 AF (7.9%), while reported non CAW WDS production decreased by 118 AF (8.4%), relative to production in WY 2008.
The
comparisons above do not include production from CAW’s satellite systems
(Bishop, Hidden Hills and Ryan Ranch Units) that derive their source of supply
from the Laguna Seca Subarea (LSS) of the
