Residents will also see a 2.6% increase in their refuse rates, according to the city.
The increase will become effective Oct. 1 and will be reflected in residents’ November bill. According to a press release from the city of Southlake, sewer collections will increase by $0.42, and the maximum charge customers will see is $74.78 per month.
The Denton Creek and Central Wastewater Regional wastewater plants are managed by the Trinity River Authority, which supplies sewer treatment to 98% of Tarrant County, including Southlake.
According to Vanassa Joseph, communications manager for the Trinity River Authority, the proposed budget for fiscal year 2020-21, which will be approved by the board of directors in October, was presented to city customers and approved.
“For the 2021 budget, the projected wastewater flows from customer entities contributing to the Denton Creek Regional Wastewater System and the Central Regional Wastewater System will both increase by 6.34% and 2.99%, respectively. Southlake is a customer of both DCRWS and CRWS,” Joseph said in an email statement.
The proposed budget for FY 2020-21 represents that year’s projected increases in wastewater flow treatment, maintenance, debt for infrastructure capital improvement as well as processes ensuring all plants meet all safety and regulatory requirements.
