In an effort to cover the cost of several large but routine improvements to the city's water and sanitary sewer infrastructure in the coming years, Lakeville will be raising water and sewer rates for residents and businesses each year over the next decade.
After reviewing an analysis of its current sewer and water funds prepared by Springsted Inc., the city chose a scenario that would raise water rates by 4.25 percent annually, beginning in 2014 and extending through 2023.
Sanitary sewer rates will go up by 6.35 percent from 2014-16, 6 percent in 2017, 2.9 percent in 2018 and 2.5 percent each year from 2019-2023.
The city will also use debt financing over nine years to pay for the projects, including $15.8 million for the water fund and $2.2 million for the sewer fund.
For an average household using 18,000 gallons of water a quarter, the sewage, water and streetlight bill would increase by $5.21 per quarter next year, or about $20 a year, to $102.37. By 2022, the rate per quarter would be about $119.73, according to the Springsted report.
Some of the projects — such as replacing old water-main pipes — need to be completed simply because of the city's age.
"Replacement of water systems in a young town like Lakeville is somewhat of a new pressure for us," said Steve Mielke, city administrator. The city has begun making such replacements over the past five to 10 years, he said.
Other capital expenditures include updating lift stations and building a new water tower in the coming years, he said.
