Also, the number of times per day that the cows are milked contributes to water use. Conservation requirements for dairies are based on water use per cow depending on whether the cow is lactating or not. Conservation potential at a dairy can be determined by the degree to which water is reused or recycled. The First and Second Management Plans require all other industrial users to recycle water to the maximum extent feasible. The plans also require minimizing waste and prohibit the use of water for single-pass heating and cooling systems.
Effluent use is encouraged when available and economically feasible.
Once conservation requirements have been established for the major water users within the AMA, it becomes imperative that a process be established to ensure that the requirements will in fact be met. The Arizona Department of Water Resources has developed a compliance and enforcement program associated with the provisions of the Groundwater Code and the management plan. This compliance and enforcement program is comprised of a number of elements. First there is an annual reporting requirement associated with each water rightholder. Annual water withdrawal and use reports are filed by rightholders and are reviewed by ADWR staff.
