Chandler Heights Citrus Irrigation District (CHCID) is 1460 acres of land in southeastern Maricopa County. Some of CHCID is within the Town of Gilbert. Most of it is unincorporated Maricopa County. It is bounded, approximately, by 172 nd street, Riggs Road, Sossaman Road, and Hunt Highway.
Historically CHCID was citrus groves with a few houses. In recent years it has changed to mostly single family homes, a few commercial citrus groves, and a few businesses and apartments.
There are currently 900 domestic water services, and over 95% of the land within CHCID is eligible for irrigation.
The CHCID primary water source is well water, which has been classified by ADEQ as groundwater under the influence of surface water.
The domestic water system can be served by two wells. Well #5 is the primary source for drinking water. Well #6 is normally used for irrigation water, but is the alternate source of domestic water.
The domestic water system also has a tie in to Queen Creek Water Company that can be used to provide domestic water during an emergency.
Well #5 (55-608808) Depth to water in 2005, 308 feet.
Well #6 (55-608811) Depth to water unknown. Presumed to be about the same as well #5.
The CHCID system has one treatment plant. The system consists of 2 wells, 2 storage tanks (450,000 gallons total), one hydropneumatic pressure tank, a main pump house, a backup pump house, a chlorination building, an emergency tie in to another water system, and a distribution system.
The system has two wells, but is configured to only use one well at a time. If a maintenance or emergency event requires changing water sources, then the switch to the alternate source is done manually.
The system has two pump houses, but the backup pump house has very limited capacity and is not capable of meeting any reasonable level of customer demand on its own.
The distribution system is almost entirely 6” PVC pipe. There are a few small section of 4” pipe that are being dealt with as part of an upgrade plan.
The system is mostly looped, but there are a few dead ends that are also part of an upgrade plan.
Deleted for security reasons .
The tie in to Queen Creek Water Company is a one way connection intended to serve CHCID during an emergency. It has been switched on with less than 30 minutes notice in the past.
It has also been used as a convenience to CHCID during major construction and maintenance projects by pre-scheduling a non-emergency use period with Queen Creek Water Company.
Describe monthly system production data categorized by the system’s sources of supply:
400,000 gallons per day (winter).
600,000 gallons per day (summer).
18,000,000 maximum monthly demand.
950,000 gallons peak day
CHCID has sold no water to another water system.
CHCID has bought a relatively small amount of water.
All amounts are in acre feet.

Meteorological and hydrological conditions are normal.
Meteorological drought is in progress for multiple years, but hydrological conditions are still good.
Meteorological drought has been in progress for years and is still in progress. Hydrological conditions are degrading. Water tables are noticeably lower.
Water tables have fallen and are not expected to rise. Meteorological conditions are such that no immediate improvement is expected.
Water tables have fallen significantly and meteorological conditions are such that water tables are expected to continue to fall without serious changes in water usage.
The primary method of informing residents about the ongoing drought has been and will continue to be the irrigation newsletter. The irrigation newsletter works well to keep the issue of a potential water shortage in the minds of residents, and to update them at least twice a year on recent meteorological history and climate forecasts.
The District website is also used for distribution of information on drought forecasts and conservation. It contains copies of the irrigation newsletters, and will have more information added during 2007.
If the drought stage reaches stage two or greater then the District will add an additional special insert to the irrigation mailing that focuses only on drought related issues. In addition the District will hold public meetings that focus on drought issues. The District is small enough for a single public meeting to reach 20% of the adult population.
The District will not take additional steps to develop substitute supplies beyond the existing connection to Queen Creek Water Company during a low stage drought condition.
The District is an active member of the East Valley Water Forum (EVWF). The EVWF does promote cooperation between water suppliers in the eastern Salt River Valley. If an opportunity to develop substitute supplies came about because of a water transport agreement between EVWF members, then the District would seriously consider it.
If there is significant concern about a long term or severe drought condition then the District may be forced to develop a surface water substitute supply. The District has an allotment of CAP Municipal and Industrial water that is currently not used. Surface water processing infrastructure could be developed, but would be overly expensive due to the Districts small size. It might be more cost effective to trade the allotment.
Water audits of both the domestic and irrigation systems have been performed in the past and should continue to be performed in the future.
The District has provided informal help to residents with unexplained high domestic water bills in the past. The District may need to develop a more formal support program for residents with high bills.
CHCID rates are not subject to approval by AAC.
Rate structures that encourage efficient use of water are worth considering but may be difficult to implement effectively. The CHCID area is semi-rural and it will be difficult to distinguish between inefficient use of water and maintenance of livestock or a large vegetable garden without continuous inspection by District personnel.
Conservation education tips are readily available from a variety of sources and can be distributed to residents through irrigation newsletters and the District website. We expect the EPA, ADWR and ADEQ to be good sources of information and programs that we can pass on to residents.
The program and tips we would have to prepare ourselves would be on irrigation best practices for new residents.
