Condensate recovery is a process to reuse water produced by air conditioning systems. Cooling systems rely on evaporator coils, which produce moisture. Buildings can capture and reuse this high quality water instead of draining it to the sewer. This can help reduce water and wastewater bills.
In Austin, a condensate recovery system can produce one gallon of condensate water per minute or more than 1,400 gallons a day. This is often enough for landscape irrigation needs and for the system to pay for itself in less than six months.
"Blended systems" that combine rainwater harvesting and condensate recovery are commonly used for irrigation.
Condensate recovery is typically cost-effective in buildings over 100,000 square feet. It is especially effective in shopping centers or warehouses where there is a high degree of exchange between indoor and outdoor air.
Retrofit projects to recover and use air conditioning condensate can receive up to $100,000 through Bucks for Business. To be eligible, facilities must have been constructed before September 6, 2017.
