Purified toilet water could soon be flowing through Californians' taps as the state battles drought

• California approved a measure allowing it to convert wastewater into drinking water.
• The measure comes as the region has battled severe drought over the past few years.
• Other states have already adopted measures that would purify wastewater.

Californians could soon have sewage waste coming out of their taps — purified, of course.

California's State Water Resources Control Board recently approved regulations allowing water systems to convert wastewater, like sewage and toilet water, into purified water that Californians can drink.
