Clean Water Sources

​Ground Water Reclamation is treating dirty groundwater and replacing it underground for reuse. Also known as water recycling. Water recycling is reusing treated wastewater for beneficial purposes such as agricultural and landscape irrigation, industrial processes, toilet flushing, and replenishing a ground water basin (referred to as ground water recharge). Water recycling offers resource and financial savings.

Wastewater treatment can be tailored to meet the water quality requirements of a planned reuse. Recycled water for landscape irrigation requires less treatment than recycled water for drinking water. No documented cases of human health problems due to contact with recycled water that has been treated to standards, criteria, and regulations have been reported.

Desalination: purifying ocean water into drinking water

Desalination is Critical to Orange County’s Water Supply (PDF)

Under natural conditions, osmotic pressure would drive water with a lower concentration of dissolved salt though a separation membrane toward water with a higher concentration of salt. In the reverse osmosis (RO) process, pressure is applied to overcome this natural osmotic pressure and reverse the movement of water by driving it through RO membranes.

The process removes over 99% of the salt and other minerals, creating fresh water from roughly half of the intake volume. The remaining seawater concentrate is returned to the ocean.
