The City of Allen purchases water and wastewater services from the North Texas Municipal Water District and then delivers it to Allen residents. This year, the NTMWD has projected a rate increase of about 10% per year for the next five years. This NTMWD rate increase will cause residents to see an increase in their monthly bill. Beginning Nov. 1, a customer using an average of 10,000 gallons per month will see an $8.18/month increase in their utility bill for water and wastewater services. Allen residents will continue to pay a lower rate than neighbors in Frisco, McKinney, Plano and Richardson, and the rate will still be significantly lower than the state average.
