Now, it will work on a standard for potable use of\u00a0<\/span><span class=\"a\">recycled water. Gov. Jerry Brown has signed AB 574, which directs state\u00a0<\/span><span class=\"a\">agencies to develop regulations for direct potable reuse of recycled water by<\/span><span class=\"a\">\u00a0blending it with raw water in the\u00a0<span class=\"l6\">pipes leading into a water \ufb01ltration plant.<\/span><\/span><span class=\"a\">Under the new law, by 2021, the California State Water Resources Con<\/span><span class=\"a\">trol Board must adopt uniform criteria for augmenting raw water with recy<\/span><span class=\"a\">cled water, and it requires the board to establish a framework for the\u00a0<\/span><span class=\"a\">regulation of potable reuse projects by\u00a0June 1. The law builds on a\u00a0previous\u00a0<\/span><span class=\"a\">one that directed the water board to establish rules for recharging groundwa<\/span><span class=\"a\">ter and adding recycled water to a reservoir. At the same time, the law pro<\/span><span class=\"a\">hibits the board from adopting criteria if its expert advisory panel determines\u00a0<\/span><span class=\"a\">there would be a threat to public health.\u00a0\u00a0<\/span><span class=\"a\">Supporters of the law pointed out the need for California to develop alter<\/span><span class=\"a\">native sources of water to serve its population in the face of recurring\u00a0<\/span><span class=\"a\">droughts.<\/span><span class=\"a\">\u201cCalifornia is a world leader in potable reuse, using highly puri\ufb01ed recy<\/span><span class=\"a\">cled water for drinking water purposes.
