Water, wastewater related rates to increase October 1

Increases to appear in November utility bills


Because of the rising cost of water purchased from the supplier, coupled with the increased costs associated with storing and distributing water to residences and businesses, the rates for these services will be readjusted over the next three years.

Increased costs for managing storm water collection will affect those monthly rates as well.

Water purchased by the Town from the North Texas Municipal Water District is increasing in cost annually, and those increases aren’t necessarily passed along to consumers. This is the case because the Utility Fund, a separate mechanism for financing water, wastewater and solid waste, is self-sustaining. The Utility Fund is kept solvent by ensuring that charges related to utility service for all customers is equal to the cost of those services. As those costs rise, so must the charges.

While the Council and staff have been diligent in attempting to keep those costs as low as possible, the cost of purchasing water and the costs associated with distributing that water to homes and businesses continue to rise. As a result of a comprehensive study on water and wastewater rates, the Town Council has approved a rate adjustment, the first since 2012.

For customers with a one-inch meter, which is the majority of customers, the minimum monthly service charge rises from the 2016 rate of $18.54 to $19.85 starting on October 1; $21.25 starting on October 1, 2018; and $23.20 starting on October 1, 2019. Customers with larger-sized meters will experience similar increases.

As for water utilization charges, called volumetric charges, those rates will also rise. As an average, the rate for utilization of 0-10,000 gallons rises from the 2016 level of $3.74 to $4 starting October 1; $4.28 starting on October 1, 2018; and $4.67 starting on October 1, 2019. Using the same starting dates, the rates for 10,001 to 40,000 gallons go from the 2016 cost of $5.60 to $5.99, $6.41; and $6.99. Higher volumetric rates show similar increases.

Monthly service charges for wastewater will also increase over the next three years. These rates will rise from the 2016 rate of $22.63 to $25.35 starting on October 1; $28.40 starting on October 1, 2018; and $31.85 starting on October 1, 2019. The cost per 1,000 gallons of wastewater increases from the 2016 rate of $3.52 to $4.15; $4.90; and $5.78 over the next three years.

Rates for commercial customers are also seeing an increase over the next three years. The new rates will be reflected in utility bills arriving in homes and businesses on or around November 20.

Similarly, maintenance and repair of the Town’s storm water and rain runoff facilities, mandated by state and federal law and funded by the Drainage System Utility Fee, will also reflect an increase.

For single family residential properties of up to 10,000 square feet, the monthly fee will increase from $1.85 to $3. SFR properties over 10,000 square feet will see rates rise from $4 to $5.15. Commercial rates will rise from $0.057 per 100 square feet of impervious area to $0.10 per 100 square feet of impervious area.

Eligible seniors may receive a credit of the Drainage System Utility Fee by applying for the Senior Affordability Discount at the Utility Billing Office, 121 West Broadway. Applications are also available on the Utility Billing page at www.prospertx.gov.

Periodic rate adjustments are unavoidable, as the Utility Fund must operate “in the black,” that is, without carrying debt or deferring debt to later years. This is the case with all self-sustaining funds, of which virtually every Utility Fund-type mechanism is based.

Water conservation and prudent use of water resources have proven to save both water and money. Water conservation advice is available at www.prospertx.gov/government/departments/water-conservation/
