California has invested $1 billion in water recycling projects across its territory. But while recycled sewage water is purified and entirely safe, the idea is not universally supported. The reason is mostly psychological, according to the National Journal. Even though people realize that recycled water is treated and drinking it poses no risk to their health, many would still be reluctant to do so.
Yet any source of fresh water is part of the water cycle that involves all living things on the planet at some point. Water recycling is sustainable and cost-effective in comparison to other water treatment methods, so with the right public awareness programs, people's perception of recycled water could improve significantly, according to the National Journal.
In fact, Orange County has found a way to do this: adding an extra step to the water-recycling process. For the last eight years water utilities in the county have been replenishing a local aquifer with recycled wastewater. It's an idea that has been accepted well by local communities, the National Journal said.
