Scituate officials have backed away from a recommendation to raise water rates by 35 percent, opting instead for a 10 percent increase this year. But another increase could come as early as next year.

The latest increase, which is intended to partially resolve problems with discolored and distasteful water, is estimated to raise the water bill for the average family of four, which uses 90,000 gallons of water annually, to $418 a year from $386 a year. The rates take effect with the bills that go out at the end of this month.
