Recycled Water Rules
Maricopa has no mandatory recycled-water rule; instead, Maricopa City Code § 18.125.040 offers a voluntary sustainable-development incentive for it. Feature #9 in the Water Efficiency category credits a project that 'incorporates purple piping (for reclaimed water) for irrigation of landscape areas or other nonpotable reclaimed water use,' and stacking that with other qualifying features under § 18.125.030 can earn expedited review, extra building height, a smaller setback or reduced parking.
