Using water wisely is paying off for Manteca residents.Reduced water use during the first eight months of this year kept $1.8 million in the pockets of Manteca residents and business. That is based on roughly a 28 percent water savings over the water consumption level for the same January through August period of 2013.And the savings are going to get better for 663 Manteca households that have taken advantage of the City of Manteca’s rebate programs that offer $100 for those who buy high efficiency washing machines and $75 for high efficiency toilets. The city has doled out $59,500 from the water enterprise fund since July 2015 to encourage households to save water.
