TWDB Approves Financing for Arlington Wastewater Improvements

The Texas Water Development Board recently approved $5,151,694 in financial assistance to the City of Arlington to improve the City’s wastewater system with a wastewater collection line replacement project.

The TWDB funding will include a low-interest loan for $4,435,000 and $716,695 in green subsidy or loan principle forgiveness from the Clean Water State Revolving Fund. In addition to more than $700,000 in loan forgiveness, TWDB estimates that the City will save $783,911 in interest charges over the low-interest loan’s lifetime.

Construction on the main replacement project is projected to begin this summer and conclude by 2020. The project will include:

  • Replacement or rehabilitation of four wastewater creek crossings, which includes approximately 1,180 feet of 8-inch to 12-inch diameter wastewater main. These creek crossings are at risk of failure due to erosion.
  • Replacements of about 1,000 feet of 66-inch diameter wastewater main located near Village Creek.
  • Replacements of about 580 feet of 27-inch diameter wastewater main that crosses under Interstate 20.

TWDB is a state agency board that collects and disseminates resources and information regarding the development of Texas’ water resources. The TWDB administers cost-effective financial assistance programs to cities for the construction of water conservation programs.

In December, the TWDB approved a request from the City of Arlington for up to $79.5 million in financing from the Drinking Water State Revolving Fund for the design and construction of improvements to the City’s Pierce-Burch Water Treatment Plant. The assistance is a low-interest loan and, reduced interest costs will save the City about $9 million over the next 20 years, according to the TWDB.
