The Client required engineering, design, procurement and construction management services of multiple water conservation and energy savings projects to improve the Marley and EVAPCO cooling water tower operations and reduce plant water consumption by an estimated 5,000,000 gallons per year.

This project involved a plant retrofit project that required extensive field work to complete the design. Continual communication between the plant’s operations was required such that construction activities would not interfere with production. Strict health and safety protocols were followed as the major of construction was completed during the COVID-19 pandemic.

TAI’s multidiscipline services were used on the following projects:

1. Water Reclaim/Collection System
2. Cooling Tower Variable Flow
3. Cooling Tower Sweep System
