Plastic lumber:
Use plastic lumber to replace wooden slats.
    
Use RO water:
Investigate use of RO water as input if mineral build-up is a problem.
    
Use other wastewater streams:
Look at other wastewater streams as source for cooling tower water.
    
Monitor water quality:
Continuously monitor water quality and adjust treatment chemical concentration.
    
Blowdown water:
Use blowdown water for non-critical cleaning applications or as fire pond water.
