Treated effluent is extensively used for agricultural and municipal irrigation in the United States and has been regulated by statutes at the state and federal level since the 1970s. When treated effluent cannot be used for irrigation, it is often used for artificial groundwater recharge or as a supply for natural or artificial wetlands. As competition for scarce water resources increases, and with more pre-treated effluent due to population growth, we can expect even greater use of treated effluent for irrigation, recharge, and environmental uses. While the current experience with the use of treated effluent has been positive, there are short- and long-term concerns about its use, and thus about the sustainability of these practices.
This Conference aims to present and discuss various concerns regarding water reuse and non-traditional sources of water for irrigated agriculture. Implications for groundwater recharge and environmental concerns will also be explored.
A Plenary Session Tuesday afternoon will begin with a Keynote Address, followed by invited presentations from leading water resources professionals.
Presentations during Tuesday, Wednesday and Thursday lunches and Wednesday dinner will provide additional perspectives for Conference participants. Receptions, meals, breaks and tours will provide excellent networking opportunities.
A Session on Thursday afternoon will feature a series of presentations which summarizes new water infrastructure developments in the western U.S.
The Conference will also include field tours on Tuesday morning and Friday to see water resources and irrigation activities in the Phoenix area.
An Exhibition will be held Tuesday evening, Wednesday and Thursday. To maximize opportunities for exhibitors to meet with Conference participants, several functions will take place in the exhibition room, including the Tuesday opening reception, and continental breakfasts, lunches and coffee breaks on Wednesday and Thursday, and reception and dinner Wednesday.

The Tour will visit the Riparian Preserve, Salt River Project Eastern Canal, and the Town of Gilbert drinking water treatment plant. In 1986, Gilbert made a commitment to reuse 100 percent of its effluent water. The Town’s desire to create innovative and unique ways to combine water resource development with wildlife habitat, educational and recreational opportunities led to the development of the Riparian Preserve in 1999. Of the 110 acres, 70 acres make up the seven water recharge basins that are filled on a rotating basis with treated effluent and allowed to percolate into the aquifer where it is stored for future use. One of the ponds has a unique distribution stream that mimics the action of an ephemeral desert stream. An additional lake is filled with reclaimed water, and is designated as an urban fishing resource through the Arizona Game and Fish Department. The Preserve is organized into various vegetative zones ranging from marshlands to native riparian and upland vegetation areas. Approximately 298 species of birds have been identified on the site, and many insects, fish, amphibians, reptiles, and mammals have found homes there as well. Over 4.5 miles of trails weave through the park, and there are interpretive education panels on wildlife and vegetation throughout. The Riparian Preserve is one part of the property known as Water Ranch, which extends from Greenfield Road east to Higley Road, encompassing the majority of the land between Guadalupe Road and the utility easement. Water Ranch includes the Southeast Regional Library building, the Salt River Project Eastern Canal, and the Town of Gilbert Drinking Water Treatment Plant.
Friday, October 19, 8:00 a.m. - 6:00 p.m.
The Pima-Maricopa Irrigation Project is a tribal program operated through an annual funding agreement with the U.S. Bureau of Reclamation. Since January 2010, P-MIP has constructed more than $350,651,000 in projects that total 85.37 miles in length. This includes pipeline and open channel canal, with the latter going from a 34-foot bottom (2,000 cfs) down to a 2-foot bottom (15 cfs). In addition, the Project has expended more than $43,228,000 on design, $22,322,00 on cultural resources mitigation and contributed $13,587,151 to the San Carlos Irrigation Project for the Community’s cost share in the SCIDD-designed and constructed Florence-Casa Grande Canal and headworks rehabilitation.
The tour of the P-MIP system will include a little history that sets the stage of why P-MIP is constructing the new irrigation system. The tour will then focus on various elements of the system that P-MIP has constructed during the past 10 years. This will begin at the Ashurst Hayden Diversion Dam improvements completed by SCIDD in 2011, and include a visit to the construction of the Florence-Casa Grande Canal reach 1. The tour then goes to the off-reservation Pima Canal MP 11.3 check structure and its appurtenances, before visiting the Southside Canal and the flood protection system. A trip to the 4 Mile Post Lift Station will be followed with a visit to the Community’s first Managed Aquifer Recharge facility.
After lunch, the tour will visit the new 16-mile long Casa Blanca Canal, including the four siphons that are part of the canal; and go to the Santan IB canal and the new Canal 9, both under construction, and concludes with a tour of the Memorial Pipeline inlet structure.
