Central Highlands Planning Area Cultural Water Demand - Municipal Demand

Cultural water demand in the Central Highlands Planning Area averaged approximately 83,200 AFA during the period from 2001 to 2005.  As shown in Figure 5.0-19, the agricultural demand sector was the largest use sector with approximately 37,500 acre-feet of demand, 45% of the total.  Municipal demand was the second largest water demand sector with about 33% of the total planning area demand or an annual average of 27,400 acre-feet during the period 2001-2005. Municipal demand is primarily met by groundwater.  Industrial demand, mainly related to mining, accounted for 18,300 acre-feet, 22% of the total average demand during this period.

Municipal Demand

Municipal demand is summarized by groundwater basin and water supply in Table 5.0-11.  Average annual demand during the period 2001 to 2005 was 27,425 acre-feet.  Ninety-five percent of this demand was met by groundwater.  A small amount of surface water is used in the Salt River Basin at Salt River lake facilities and on the Fort Apache Indian Reservation at Cedar Creek, a small community southeast of Carrizo.  In the Verde River Basin surface water is used at several locations including the Beaver Valley Water Company, Bonita Water Company (Payson), Camp Navajo, Kohl’s Ranch, Pine Water Association, Stoneman Lake Water Company and the Town of Jerome, which uses about 80 AFA of the 400 AFA it diverts from 12 springs (Town of Jerome, 2008).  Effluent is used for turf irrigation in the Verde River and Tonto Creek basins.

Table 5.0-11

Primary municipal demand centers are located around Cottonwood, Globe-Miami, Payson, Sedona and Wickenburg.  Municipal demand in the Verde River Basin accounts for 59% of the total municipal demand.  By comparison, there is relatively little municipal water demand in the Agua Fria Basin.  It is estimated that about eleven percent of the planning area population is not served by a municipal water provider. 

Eight water providers served 450 acre-feet or more in 2006 for a total of 14,158 acre-feet.  Their demand in 1991, 2000 and 2006 are shown in Table 5.0-12 and discussed briefly below.  Prior to 2006, municipal utilities served only Globe, Payson and Wickenburg.  Beginning in 2005, the City of Cottonwood began acquisition of the four private water companies serving the town; Clemenceau Water Company, Cordes Lakes Water Company (Cottonwood Systems), Cottonwood Water Works and the Verde Santa Fe Water Company.  By 2007, the City of Clarkdale had acquired the Cottonwood Water Works system serving Clarkdale. Municipally-owned systems have more flexible water rate-setting ability than private water companies, which are regulated by the Arizona Corporation Commission.  In addition, municipal utilities have the authority to enact water conservation ordinances.  These authorities may enable municipal utilities to better manage water resources within water service areas.  Water provider issues are discussed in Section 5.0.8.  For information on annual water demand by individual community water systems in this planning area see ADWR's Community Water System Program annual water use reporting summary.

Arizona Water Company-Miami

The towns of Miami-Claypool are served by Arizona Water Company.  About 87% of the approximately 3,250 connections are residential. The Miami water system is served by 17 wells and has a two-way emergency interconnection with the City of Globe.  Water levels in wells ranged from 109 feet to 860 feet below land surface in 2006. (Arizona Water Company, 2007a)  In 2006, 968 acre-feet was pumped from 13 wells. Of this total, 641 acre-feet was delivered for residential use, 245 for commercial use and 10 for “other”.

City of Globe

The City of Globe has an adequate water supply designation and serves about 7,700 customers from five active wells.  Four of these wells are located in the Safford Basin in the Southeastern Arizona Planning Area.  About two-thirds of the water demand is residential and one-third is non-residential.  The City has a water conservation plan that it credits with helping to keep water demand in check.  Water levels in wells ranged from 40 feet to 650 feet below land surface in 2005. (City of Globe, 2005)  In 2006, Globe withdrew 1,603 acre-feet from five wells and delivered 938 acre-feet to residential, 353 acre-feet to commercial, 60 acre-feet to turf and 90 acre-feet to “other”.

Town of Wickenburg

The Wickenburg municipal water system serves groundwater to about 5,100 residents.  In 2007 it withdrew almost 1,730 acre-feet from four wells. Of this, 895 acre-feet was delivered to residential customers, 630 to commercial and 204 to “other”. It operates the Wickenburg WWTP which treated 444 acre-feet of effluent in 2007, all of which was discharged to infiltration ponds.

Arizona Water Company-Sedona

Arizona Water Company serves the town of Sedona.  The system has 14 active wells and about 5,500 connections, of which 78% are residential.  Sedona has a high percentage of seasonal residents, and daily visitors contribute to a relatively high use rate of 244 gallons per capita per day (gpcd) (USBOR, 2003).  The system also serves commercial customers and turf facilities.  The service area includes central Sedona from Red Rock Loop Road to east of downtown.   The Valley Vista “sub-system” serves an area south of Verde Valley School Road, mostly west of Highway 179.  Arizona Water Company maintains an emergency two-way interconnection with the Oak Creek Water Company. Groundwater depth average about 220 feet in utility wells. (Arizona Water Company, 2007b)  In 2006, 3,332 acre-feet was withdrawn from nine wells. Of this total, 2,077 acre-feet was delivered to residential customers, 938 to commercial customers and 58 to “other”.

Big Park Water Company

Big Park Water Company serves the Village of Oak Creek, an unincorporated community south of Sedona along Highway 179.  It has about 2,800 connections, of which 91% are residential, and a per capita rate of about 198 gpcd (USBOR, 2003).  It does not serve turf facilities.  Depth to water in the seven system wells averages about 390 feet and water levels are reportedly stable.  Big Park Water Company has an interconnection with Little Park Water Company. (BPWC and LPWC, 2007)  Both companies have designations of Adequate Water Supply.  In 2007, Big Park withdrew almost 880 acre-feet of water from six wells and delivered 0.3 acre-feet to Little Park Water Company, 684 acre-feet to residential and 150 acre-feet to commercial customers.

Camp Verde Water System, Inc.

The Camp Verde Water System is a private water company consisting of the larger Mongini System and smaller Verde River Estates System. There is no physical interconnection between the two systems. There are a total of four active wells that serve both systems. In 2006, 460 acre-feet was withdrawn by the Mongini System, which served 265 acre-feet to residential and 183 acre-feet to commercial customers. Twelve acre-feet was withdrawn by the Verde River Estates System of which eight acre-feet was delivered to residential customers in 2007.

Cities of Cottonwood and Clarkdale

Prior to 2006, Cottonwood Water Works and Cordes Lakes Water Company were the two large private water companies serving the City of Cottonwood.  The Cottonwood Water Works system also served the community of Clarkdale with a combined 4,600 connections of which 97% were residential.  The Cordes Lakes Water Company served a population of almost 7,700 consisting of six separate systems in the Verde Village area.  (A separate, smaller Cordes Lakes Water Company System serves the community of Cordes Lakes in the Agua Fria Basin).  The estimated gpcd rate of Cottonwood was about 148 gpcd and Clarkdale about 193 gpcd (USBOR, 2003).

In 2006, the City of Cottonwood acquired four systems: Cottonwood Water Works, Cordes Lakes, Clemenceau and Verde Santa Fe.  These systems withdrew a total of about 3,150 acre-feet of water from 28 wells in 2006.  Separate deliveries to residential and non-residential customers were not reported on the 2006 Community Water System annual reports. In 2009, the City received a Designation of Adequate Water Supply for its water service area.

In 2007, The City of Clarkdale acquired the Cottonwood Water Works-Clarkdale system which served about 3,000 people and pumped about 400 acre-feet in 2006 (Cottonwood Water Works, 2007).

Green Valley Park

Green Valley Park in Payson.  Payson's water demand declined by 7% between 2002 and 2003.

Town of Payson

The Town of Payson pumps groundwater from 32 active wells to about 14,000 residents.  Most wells are located in the Verde River Basin and some are in the Tonto Creek Basin.  It also supplies water to parts of the Tonto Apache Indian Reservation.  The town estimates that there are also about 300 to 400 domestic wells operating within its service area. Because the local granite aquifer has limited storage capacity, Payson is drought-sensitive and dependent on sufficient rainfall and snowmelt for an adequate drinking water supply (City of Payson, 2007).  Payson monitors water levels in its wells regularly to gauge water supply availability and has aggressive water conservation, effluent reuse and drought programs.  Water levels in wells trigger the town’s drought response.  Payson’s water demand declined by 7% between 2002 and 2003, which it attributes to conservation efforts (Maguire, 2005).  In 2006 Payson withdrew 1,815 acre-feet from 35 wells.  It delivered 31 acre-feet to the Tonto Apache Indian Reservation, 1,299 acre-feet to residential customers and 390 acre-feet to commercial customers.

About 80% of Payson’s population is connected to the Northern Gila County Sanitary District sewer system that provides wastewater treatment for Payson and much of the surrounding area. Current system inflows are about 800,000 gallons daily, or 50% of capacity. The District’s effluent is used for a variety of irrigation projects and ground water recharge, including the Green Valley Lake project. The 48-acre Green Valley Park was developed jointly by the Town of Payson Water Department and the Sanitary District. Treated effluent from the district’s water treatment plant fills a 10.5-acre lake used for boating and fishing and adjacent irrigated areas and recreational facilities. (Payson Regional Economic Development Corporation, 2006)  Another effluent recharge project, Rumsey Park, is in the pilot phase. 

Golf course demand by municipal and industrial facilities, basin location and source of water is listed in Table 5.0-13.  Total golf course demand was about 5,700 acre-feet in 2008, almost 7% of the total planning area demand. Effluent is an important water supply for golf course irrigation, accounting for 17% of the golf course demand in 2006.  Municipal water providers served about 2,200 acre-feet to golf courses in 2008.  Of this, 1,555 was groundwater and almost 680 acre-feet was effluent. Golf courses with their own facility wells, considered “industrial users”, used about 2,400 acre-feet of groundwater, 800 acre-feet of surface water and 300 acre-feet of effluent in 2008.  The demand of these golf courses is included in the industrial category. Most golf courses are located in the Verde River Basin.
