Congratulations to the City of Roma, Texas for their Drinking Water State Revolving Fund (DWSRF) funding approval by the Texas Water Development Board (TWDB) in the amount of $15,005,492. The funding includes $9,575,492 in principal loan forgiveness and a 0% interest loan of $1,720,000. The City also saved approximately $3 million in financing costs via the DWSRF interest rate subsidies.
The funding will restore the City’s 5.15 MGD treatment capacity at the 30-year-old Water Treatment Plant through major rehabilitation and replacement of the critical components from raw water to finished water.
eHT prepared the application and worked with the TWDB staff to blend 2021 and 2025 DWSRF funds to achieve a project that is affordable for the City’s ratepayers. eHT also identified the grant sources and eligible amounts from the DWSRF disadvantaged program, the DWSRF Very Disadvantaged program and the DWSRF Urgent Need program to maximize the amount of principal forgiveness.
eHT will provide project management, design and construction phase services for this much needed project. #txwater #romatx #watertreatment ... See MoreSee Less
