Water prices will go up and sewer prices will go down, following a unanimous selectmen's vote approving the rates for 2013-14.
The increase in water rates will be 10.75 percent, while the decline for sewer rates will be 2.4 percent, according to Department of Public Works Director Joe Lynch.
“For the vast majority, the net effect is a 2.2 percent increase,” Lynch said. For a four-person household, that comes out to about a $40-a-year increase.
Milton uses a four-tier system, based on how much water is used or discharged per quarter.
The water rates are $5.18 for each 100 cubic feet for the first 600 cubic feet, $6.27 for each 100 cubic feet from 601 to 3,000, $6.91 for each 100 cubic feet from 3,001 to 6,000, and $7.39 for each 100 cubic feet above 6,000.
Sewer rates are $5.86 per 100 cubic feet for the first 600 cubic feet, $11.06 for each 100 cubic feet between 600 and 3,000, $12.18 per 100 cubic feet from 3,000 to 6,000, and $12.99 per 100 cubic feet for above 6,000.
The rates are based on assessments from the Massachusetts Water Resources Authority, which are determined by how much water was used in the previous year, according to Lynch.
Lynch said new ways to organize the rates would have to be found and he would begin to look into it.
“We’re reaching the breaking point at these rates,” he said.
