Orange County's water reuse system is far bigger: http://www.ocwd.com/what-we-do/water-reuse/ http://www.ocwd.com/what-we-do/water-reuse/ The Groundwater Replenishment System (GWRS) is the world's largest system for indirect potable reuse. The system takes highly treated wastewater that would have previously been discharged into the Pacific Ocean and purifies it using a three-step advanced treatment process.
