Chlorine reduction in pumped irrigation system #254361

Asked June 15, 2015, 5:57 PM EDT

What proportion of chlorine in water from a public water supply is dissipated when distributed through overhead sprinklers?  Our club pumps its sprinklers at 5 bar.  I would imagine that the sudden release of pressure at the sprinkler head plus the droplets traveling through the air will reduce the chlorine content to a significant extent.

I ask this because our (croquet) club is starting to make the transition from conventional management of our fine turf green to a biologically based regime.  The chlorine in the public water supply may have an adverse effect on the "bugs" we are trying to encourage to reduce the thatch layer just under the grass surface.

This is a difficult question to answer without actually having measurements. You are correct some chlorine will dissipate in the atomization from your sprinkler system. 
Can you put out some tuna cans and then take them to be analyzed?
