SUMMARY: Staff has prepared a draft Water Production Summary Report for Water Distribution Systems (WDSs) within the District for Water Year 2003 (WY 2003). WY 2003 includes the period from October 1, 2002 to September 30, 2003. Preliminary computations indicate that 16,193 acre-feet (AF) of water were produced by the 45 registered WDSs in the District during WY 2003. The largest WDS in the District, California American Water (Cal-Am), accounted for 14,871 AF, or 92% of total production reported by WDSs.

RECOMMENDATION: This report is for information purposes only. The Board should review the draft report and provide any comments or questions to staff. Staff will complete the final report, incorporating any late revisions, if this item is approved with the Consent Calendar.

BACKGROUND INFORMATION: All owners and operators of WDSs are required to annually submit water production information from WDSs within the District. WDSs are defined 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 two or more connections. Ordinance Nos. 96 and 105 amended District Rules to require WDS permits for “single-connection systems” consisting of new wells in the Carmel River Basin and the coastal subareas of the Seaside Groundwater Basin. Three new single-connection systems (i.e., Animal Farm, Condon and Hyles) were established during WY 2003.

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 2003 is summarized in Exhibit 8-A. The systems shown are grouped by source area. This information is also incorporated into the District-Wide Water Production Summary Report, presented as Item 9 of the Consent Calendar of this packet. For comparative purposes, the Annual Water Distribution System Production Summary Report for Water Year 2002 (WY 2002) is provided as Exhibit 8-B. The report for WY 2002 was revised subsequent to its original presentation at the Board’s February 27, 2003 meeting to include backwash, irrigation and other non-revenue uses in the “delivery” total for Cal-Am. The amount of Cal-Am non-revenue water for WY 2003 is not available at this time, but will be included in the final WDS Summary for WY 2003.

Production figures for three WDSs -- Bishop, Ryan Ranch, and Hidden Hills Units -- are reported separately from the Cal-Am system, although Cal-Am owns and operates each system. The Bishop Unit has been operated by Cal-Am since September 1996, and was acquired by Cal-Am in July 1999. The Hidden Hills Unit was formerly reported as the “Carmel Valley Mutual Water Company” and was annexed into the Cal-Am system in 1993. Although water production and delivery values for the Bishop, Hidden Hills and Ryan Ranch Units are reported separately from the values for Cal-Am’s main system in this report, they are included in Cal-Am’s total production in the District-wide Production Summary Report (Exhibit 9-A) as “Cal-Am Wells Outside the Water Resources System”. In addition, production from the former Water West WDS, which was annexed into the Cal-Am service area in 1989 and integrated into Cal-Am’s main system in 1993, is incorporated into Cal-Am's total production and delivery values in this report and in Exhibit 9-A of the District-wide Production Summary Report. In addition, the Rancho Fiesta system is also part of Cal-Am, although no water has been produced from the Rancho Fiesta wells for over a decade. Water delivery to the Rancho Fiesta system was not reported separately because all water used within that system was produced from other sources within the Cal-Am main system. For WY 2003, all deliveries and connections to Rancho Fiesta were incorporated into totals for the Cal-Am main system. In WY 2002, the 22 connections to Rancho Fiesta were listed separately.

It should also be noted that the Cañada Woods WDS derives water from wells within and outside the Carmel Valley alluvial aquifer. Combined production from upland and alluvial sources for the Cañada Woods WDS in WY 2003 was 155 AF, which was 21 AF (11.9%) less than in WY 2002. Production from Cañada Woods WDS’s upland sources in WY 2003 totaled 90 AF, representing an increase of 95.7%, while production from its alluvial wells totaled 65 AF, representing a decrease of 50.0%. All of the water from these sources was non-potable and was used for irrigation and temporary construction purposes.

District-wide - Total WDS production within the District for WY 2003 was 16,193 AF. Of this total, the Cal-Am main system (i.e., not including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for 92% of the water produced by WDSs. The remaining 44 other active 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 2003 is 220 AF (1.3%) greater than the production reported for WY 2002. During WY 2003, Cal-Am system production increased by 259 AF (1.8%), while reported non Cal-Am system production decreased by 39 AF (2.9%), relative to production in WY 2002.

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, and the coastal subareas of the Seaside Groundwater Basin, was 15,421 AF in WY 2003. Total WDS production within the MPWRS increased by 279 AF (1.8%) in WY 2003 compared to production in WY 2002. More specifically, Cal-Am production in WY 2003 was 259 AF (1.8%) greater than production in WY 2002, while combined production from the 16 other active systems within the MPWRS decreased by 19 AF (3.7%), relative to production reported for WY 2002. This comparison includes production from the alluvial wells serving the Cañada Woods WDS.
