free chiller

[coastal]

i found the secret to chilled water free , well minus the price of 400 ft of 3/4 pipe and the labor invloved . i simply dug a trench 200 ft long 2ft x 2ft and layed the pipe . the system works by gravity or siphon no pump needed. it simply siphons from my main vat then goes through the ground then dumps in the sump it goes in at 78 degrees and comes out at 62 unbelievable!!! if i didnt see it for myself first hand i might not have believed it free chiller
