The Riparian Preserve in Gilbert, Arizona was set up as a place to protect wildlife, but also – and maybe more importantly – to recharge local aquifers. Several shallow ponds are flooded to give treated wastewater and occasional runoff a chance to soak into the ground. Various ponds are occasionally drained and plowed so that the surfaces do not become too impervious to the water. It is a nice, green and peaceful area very popular with local residents as a place to walk and see animals.
