WATER FILTER SYSTEM

The carbon filter-based system produces 150 gallons of water per minute at 3-5 microns nominal filtration. The system uses a triple tank with all tanks in parallel with staggered backwash and is located in building two. System shall be monitored, tested, and the water sampled to insure proper operation in accordance with manufacturers recommendations. All consumable products and supplies for this system shall be monitored, supplied, delivered and installed by the vendor.

HVAC HOT WATER SYSTEM (Closed Loop)

Hot water system for heating and reheat of HVAC systems. Water is continuously circulated in a closed loop through heat exchangers to maintained temperature set-point. Building 1- five loops, building 2, Boiler room- one loop, building 5- one loop, Building 6- one steam heated loop and one solar heated loop.

Systems must be closely monitored and sampled at least monthly; corrosion indicator coupons examined every 90 days. Water treatment shall be on an as needed basis to control any corrosion.
