SUMMARY:Staff has prepared a draft Water Production Summary Report for Water Distribution Systems (WDSs) within the District for Water Year 2005 (WY 2005).WY 2005 covers the 12-month period from October 1, 2004 through September 30, 2005.Preliminary computations indicate that 15,372 acre-feet (AF) of water were produced by the 62 recognized WDSs in the District during WY 2005.The California American Water (Cal-Am) main system, which is the largest WDS in the District, accounted for 14,038 AF or approximately 91% of the total production reported by WDSs in WY 2005.


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 WDSs 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 and additions to the Rules and Regulations governing WDSs were adopted as parts of Ordinance No. 105 in 2002; Ordinance No. 106 in 2003; Ordinance No. 118 in 2004; and Ordinance No. 122 in 2005.†††


Ten new single-parcel systems (i.e., Aiello, Bardis, Cardinalli, Cass, Evans, Grachek, Greeenwall-King, Lyon, Pospishill and Prew) and two new multiple-parcel systems (i.e., Goodrich-Potrero and Flagg Hill) were established during WY 2005.Two other pre-existing multiple-parcel systems that were not previously recognized by the District (i.e., Casanova and Page-Bouc) were also permitted during WY 2005.Additionally, the CaŮada Woods Alluvial, CaŮada Woods Upland and Monterra Ranch WDSs were merged into the CaŮada 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 2005 is summarized in Exhibit 1-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 2 of the Consent Calendar of this packet.For comparative purposes, the Annual Water Distribution System Production Summary Report for Water Year 2004 (WY 2004) is provided as Exhibit 1-B.†††


Production figures for three WDSs -- Bishop, Ryan Ranch, and Hidden Hills Units -- are reported separately from the Cal-Am main system, although Cal-Am owns and operates each system. The Ryan Ranch Unit was acquired and annexed into the Cal-Am system in November 1989.The Hidden Hills Unit, which formerly reported as the Carmel Valley Mutual Water Company, was acquired and annexed into the Cal-Am system in 1993.The Bishop Unit, which has been operated by Cal-Am since September 1996, was acquired and annexed into the Cal-Am 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 Cal-Amís main system in this report, they are included in Cal-Amís total production in the District-wide Production Summary Report (Exhibit 1-A) as ďCal-Am Wells Outside the Water Resources SystemĒ.In WY 2005, no water was produced from the former Water West WDS, which was acquired and annexed into the Cal-Am service area in 1989 and integrated into Cal-Amís main system in 1993.Water delivered to the former Water West WDS is incorporated into Cal-Am's total delivery value in this report and in Exhibit 1-A of the District-wide Production Summary Report.The Rancho Fiesta system is also included as part of the Cal-Am main system.Water delivery to the Rancho Fiesta system was included because all water used within that system was produced from sources that serve Cal-Amís main system and the Rancho Fiesta production wells have been inactive for more than 10 years.For WY 2004 and WY 2005, all deliveries and connections to Rancho Fiesta customers were incorporated into totals for the Cal-Am main system.


The production shown for Monterra Ranch includes water from wells that was sent to their desalination plant and non-potable water that was used for construction.For WY 2005, the reported percentage of unaccounted water at Monterra Ranch represents a comparison of only the amount of production at the Monterra Ranch desalination plant (42.58 AF) and reported consumption (36.52) from the desalination plant, and does not include the amount of desalination plant brine concentrate (7.12 AF), or non-potable water (61.22 AF) produced by wells that was not sent to the plant.††


District-wide - Total WDS production within the District for WY 2005 was 15,372 AF.Of this total, the Cal-Am 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 61 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 2005 is 1,286 AF (7.7%) less than the production reported for WY 2004.During WY 2005, Cal-Amís main system production decreased by 1,146 AF (7.5%), while reported non Cal-Am WDS production decreased by 139 AF (9.5%), relative to production in WY 2004. It should be noted that Cal-Amís production totals in WY 2004 and WY 2005 include 769 AF and 175 AF, respectively, that the District produced from its Santa Margarita Test Injection Well and provided to Cal-Am for delivery to customers in Cal-Amís main system.

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 14,540 AF in WY 2005.Total WDS production within the MPWRS decreased by 1,180 AF (7.5%) in WY 2005 compared to production in WY 2004.More specifically, production for Cal-Amís main system in WY 2005 was 1,146 AF (7.5%) less than production in WY 2004, and combined production from the 20 other active systems within the MPWRS decreased by 34 AF (6.3%), relative to production reported for WY 2004.This comparison includes production from the alluvial wells serving the CaŮada Woods WDS.The comparison does not include production from Cal-Amís satellite systems (Bishop, Hidden Hills and Ryan Ranch Units) that derive their source of supply from the Laguna Seca Subarea of the Seaside Groundwater Basin, which is outside the defined MPWRS.
