Orange County Water District and Orange County Sanitation District Technical Tour

Sunday, October 23, 2022 | 8:00 a.m. – 1:00 p.m. (5 hours) | PDHs 4

Orange County Sanitation District General Manager Jim Herberg and Orange County Water District (OCWD) General Manager Mike Markus will host a tour highlighting the two special districts that include operations of a wastewater district and an adjacent water district. This facility is the world's largest water purification facility for potable reuse. During the tour, you will learn about the successful partnership between the two agencies and how together they built, and are expanding, the Groundwater Replenishment System (GWRS) that takes treated wastewater and purifies it to drinking water standards. The general managers will demonstrate the wastewater treatment process, discuss groundwater management operations, and guide participants through the GWRS process.

Bottled water and lunch will be provided.
