SUMMARY: Staff has prepared a draft Water Production Summary Report for Water Distribution Systems (WDS) within the Monterey Peninsula Water Management District (District) for Water Year 2006 (WY 2006). WY 2006 covers the 12-month period from October 1, 2005 through September 30, 2006. Preliminary computations indicate that 15,440 acre-feet (AF) of water were produced by the 67 recognized WDS in the District during WY 2006. In general, recognized WDS 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 14,219 AF or approximately 92% of the total production reported by WDS in WY 2006.

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 WDS within the District are required to annually submit water production information to the District. In 1980, District Ordinance No. 1 defined 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 WDS. However, until the adoption of Ordinance No. 96 in 2001, only multiple-parcel WDS were required to obtain a permit from the District. Other refinements to the Rules and Regulations governing WDS 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.

Four new single-parcel systems (i.e., Lyon, Prew, Pospishill, R. Jones and Messenger/Melnick) and two new multiple-parcel systems (i.e., Goodrich-Potrero and Alldawell) were established during WY 2006. In WY 2005, the Cañada Woods Alluvial, Cañada Woods Upland and Monterra Ranch WDS 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 2006 is summarized in Exhibit 6-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 7 of the Consent Calendar of this packet. For comparative purposes, the Annual Water Distribution System Production Summary Report for Water Year 2005 (WY 2005) is provided as Exhibit 6-B.

Production figures for three WDS -- 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 6-A) as “CAW Wells Outside the Water Resources System”. In WY 2006, 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 6-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 2005 and WY 2006, 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 desalination plant and non-potable water that was used for construction. For WY 2006, the reported percentage of unaccounted water at Monterra Ranch represents a comparison of only the amount of production at the Monterra Ranch desalination plant (39.43 AF) and reported consumption (34.27) from the desalination plant, and does not include the amount of desalination plant brine concentrate (6.82 AF), or non-potable water (50.60 AF) produced by wells that was not sent to the plant.

District-wide - Total WDS production within the District for WY 2006 was 15,440 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 WDS within the District. The other 66 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 2006 is 68 AF (0.4%) more than the production reported for WY 2005. During WY 2006, CAW’s main system production increased by 180 AF (1.3%), while reported non CAW WDS production decreased by 113 AF (8.4%), relative to production in WY 2005. It should be noted that CAW’s production total in WY 2005 includes 175 AF that the District produced from its Santa Margarita Test Injection Well and provided to CAW for delivery to customers in CAW’s main system. No recovered water was delivered to CAW customers in WY 2006.

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 14,652 AF in WY 2006. Total WDS production within the MPWRS increased by 112 AF (0.8%) in WY 2006 compared to production in WY 2005. More specifically, production for CAW’s main system in WY 2006 was 180 AF (1.3%) more than production in WY 2005, and combined production from 18 other active systems within the MPWRS decreased by 69 AF (13.7%), relative to production reported for WY 2005. This comparison includes production from the alluvial wells serving the Cañada Woods WDS. The comparison does 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 of the Seaside Groundwater Basin, which is outside the defined MPWRS.
