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) 2008. WY 2008 covers the 12-month period from October 1, 2007 through September 30, 2008. Preliminary computations indicate that 15,563 acre-feet (AF) of water were produced by the 82 recognized WDSs in the District during WY 2008. 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 14,225 AF, or approximately 91% of the total production reported by WDSs in WY 2008.

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.

Eleven new single-parcel WDSs (i.e., Reppy, All Saints, St. Dunstan’s, Foreman, K. Griggs, Johnson, Litt, West, Carmel Hill, Colgac and Sunrise Senior Center) were established during WY 2008. 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 2008 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 2007 is provided as Exhibit 11-B. Note that the version of the Annual WDS Production Summary Report for WY 2007 presented here has been revised since it was originally presented to the Board on April 21, 2008, 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 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 12-A) as “CAW Wells Outside the Water Resources System”. In WY 2008, 62.57 acre-feet 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 2007 and WY 2008, 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 un-treated water that was produced for non-potable purposes. For WY 2008, the reported percentage of unaccounted water at Monterra Ranch represents a comparison of the amount of RO plant and brine production (56.81 + 12.55 AF) minus metered consumption and brine production (51.22 + 12.55 AF) divided by RO plant and brine production (56.81 + 12.55 AF). This percentage does not include the amount of non-potable water produced by wells that was not sent to the plant (9.53 AF).

District-wide - Total WDS production within the District for WY 2008 was 15,563 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 81 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 2008 is 208 AF (1.4%) greater than the production reported for WY 2007. During WY 2008, CAW’s main system production increased by 149 AF (1.1%), while reported non CAW WDS production increased by 59 AF (4.6%), relative to production in WY 2007.

Monterey Peninsula Water Resources System (MPWRS) - Total WDS production from the MPWRS, which includes the Carmel River and its tributaries, the Carmel Valley alluvial aquifer, the Seaside Groundwater Basin was 14,663 AF in WY 2008. Total WDS production within the MPWRS increased by 161 AF (1.1%) in WY 2008 compared to production in WY 2007. More specifically, production for CAW’s main system in WY 2008 was 149 AF (1.1%) greater than production in WY 2007, and combined production from 18 other active systems within the MPWRS increased by 12 AF (2.9%), relative to production reported for WY 2007.

The comparisons above do not include production from CAW’s smaller systems (Bishop, Hidden Hills and Ryan Ranch Units) that derive their source of supply from the Laguna Seca Subarea (LSS) of the Seaside Groundwater Basin, which was outside the MPWRS as defined during most of WY 2008. The LSS was added to the MPWRS with the adoption of Ordinance No. 135 on September 22, 2008. Because the LSS was added to the MPWRS late in WY 2008, another set of comparisons is presented below that includes production from the LSS, and future Water Production Summary Reports for WDSs will treat the LSS as part of the MPWRS. When the LSS is included in calculating production from the MPWRS, the comparisons of WY 2008 to WY 2007 are as follows. Total WDS production within the MPWRS (including LSS) increased by 244 AF (1.7%) in WY 2008 compared to production in WY 2007. In WY 2008, production by CAW from within the MPWRS (including LSS) increased by 248 AF (1.7%) and the combined production from 19 other active systems within the MPWRS (including LSS) increased by eight AF (1.9%), relative to production reported for WY 2007.
