In March, homeowners will pay 22.11 percent more for water and sewer services, following an ordinance recently passed by City Council.
The rates will again increase in 2014 by 7.69 percent. In 2015, they will increase by 7.13 percent and by 6.67 percent in 2016.
In 2017, however, water and sewer rates will increase based on the annual Consumer Price Index of utility maintenance and operation.
The increases are to benefit the Joint Water and Sewer Enterprise Fund. Wastewater Manager Art Torrez said the city needs to generate at least $30 million in 20 years to perform necessary water projects and repairs to infrastructure.
“The city of Roswell’s water rates are the most fair because they’re based on use,” Torrez said. “(The increases are) all linear and it’s all equitable.”
Sanitation rates will not be affected, he said.
A meter size of .75 inches is the most common is Roswell, he said, and in March, homeowners with meters of that size who had been paying $10.65 for the first 3,000 gallons of water used will pay $13.
All homeowners will pay $1.60 for each subsequent 1,000 gallons used, as well as $7.86 per month for sewer services, with an additional $1.17 per each 1,000 gallons.
Therefore, under the rate increase, the combined water and sewer charge with a .75-inch meter for 6,000 gallons of water used, for example, would be $29.17 a month, instead of $23.90 a month.
In 2014, the charge for the first 3,000 gallons with a .75-inch meter will be $14, then $15 in 2015 and finally, $16 in 2016.
To find an estimate of how much the new rates will cost, Torrez said homeowners could multiply their monthly water and sewer charge by 22.11 percent and add that number to the original amount.
