- Regularly inspect, maintain, and repair your cooling tower/boiler systems, which consume a significant amount of a building's water.
- Install a condensate return line on your boiler if it does not already have one.
- Check the pressure. Where system pressure is higher than 60 psi, install pressure-reducing valves.
- Reduce excessive blowdown! Many cooling towers operate below the suggested levels of total dissolved solids unnecessarily. Adjust boiler and cooling tower blowdown rate to maintain TDS at levels recommended by manufacturers' specifications.
- Consider using ozone as a cooling tower treatment to reduce water used for make-up.
- Identify all single-pass flows in your facility. These flows often are associated with equipment cooling for pumps, compressors, ice machines, air conditioners and other equipment. Consider revising plumbing to include these units in cooled recirculating loops wherever feasible.
- Shut off water-cooled air conditioning units when not needed (summer vacation).
- Determine whether an air-cooled and water-cooled HVAC system will be the most water and energy saving for your facility.
