- Continuous incoming water sampling and monitoring for the facility including pressure, temperature, pH, dissolved solids, and oxidant residual
- Addition of mixing valves at hot water outlets
- Evaluation of existing hot water return system and methods to fix deficiencies and promote proper circulation for temperature retention
- Construction drawings for the correction of dead legs and hot water return system upgrades
- Storing and chilling incoming potable cold-water supply via a chiller and heat exchangers to meet appropriate temperatures
