The Management team at SDIA is acutely aware of the drought in California. Understanding their responsibility to our environment, SDIA is working hard to help. Water restrictions have made it profitable to install a water reclamation system. It re-uses water that would be sent to sewage and turns it into energy for the rink. This lowers the cooling bill and maximizes the water efficiency. I spoke with Mark Linssen, who headed up the project.
“An average ice rink will use 3,000 gallons of water per day. At most ice rinks that water goes straight into sewage. We’ve built a water reclaimer to help turn that water into usable energy.”
Here’s how it works.
The maintenance staff at SDIA will do an average of twelve ice cuts per day. Each time the ice is cut the Zamboni must be filled with 200 gallons of hot water. And each time the Zamboni finishes an ice cut it removes about 200 gallons of ice from the rink.
This ice is put into the pit where it is melted down into water. Now in most rinks this water is sent straight into sewage as waste water.
At SDIA this water is instead sent into this large green holding tank.
From there it is pumped by this pressure bladder and pushed into the cooling tower.
The cooling tower then runs water down the metal grates below and this reduces the temperature of the refrigerant.
Just like a radiator, the water that was going into sewage is used to cool the rink.
During winter days this system will use up to 3,000 gallons each day. In the summer when the temperature rises, this system can use up to 4,000 gallons each day.
While most people will never know this system is in place, its just one of the many ways that SDIA is working to stay ahead of the curve.
