Water and sewer rates will increase Jan. 1 in the city of Frisco, largely due to increasing rate costs from the North Texas Municipal Water District.

The Frisco City Council on Sept. 17 agreed to increase water and sewer rates by 3.5 percent.

The city's rate increases came after learning the NTMWD is increasing the cost per thousand gallons of water from $1.70 to $1.88. Those rates, according to city staff members, are expected to continue increasing throughout the next 10 years, along with the cost to collect and treat wastewater.

"Our water rate is really two components, one of which we control, and one of which we do not," said councilman Jeff Cheney. "We get water rates from [NTMWD] and those are passed along to our residents. Of course we have our own infrastructure we have to pay for."

The increases are also due to the city adding 12 staff members and spending $12 million in capital projects.
