Over the next few months we're building a new house in a rural area on
25 acres. The 410 foot well is terrific, but the water has a slight
salty taste which apparently is sodium, so we'll have an undersink
reverse osmosis filter for drinking/cooking water, with a sideline
running over to the water dispenser/icemaker in the fridge.

My problem is that RO filters produce about 8 parts waste water for
every 1 part of drinking water. This water is normally routed out to
the drain pipe, which in our case would go to the septic tank. This is
a significant amount of water; for every cup of water you drink from
the RO filter faucet, 8 cups goes down the drain.

In reality, it's a totally insignificant amount of water, but there are
kits for redirecting the waste water into your hot water system.

It would take several hundred years to recover the cost of this kit.

Is there SOME way to reroute this RO waste water away from the septic
system? I hate to think of it all going in there.

It's good for the septic system.
