Chlorinated Pool Owners : Where Does Your Backwash Go?
Chlorinated Pool Owners : Where Does Your Backwash Go?
My adventures in pool maintenance continue having rebuilt both multiport valve and our pump impeller recently.
After some detective work, it appears that the waste is directed to the gravel bed area of the main fosse. This is obviously bad from a chemicals Vs. good bacteria point of view and very bad from a 400 litres per minute hydraulic destruction point of view.
Number 1,264 in an increasing series of “Why the **** did they do it like that?” moments here in Dept 47.
There are no public drains to direct this waste water to (which is probably illegal anyway), so I’m wondering if anyone else is in a similar situation and how you deal with the waste water from your pool generated by backwashing and vacuuming to waste.

Pipe goes straight to the edge of a bank and the water gushes down a gulley between our land and our neighbouring farmer's. In the 12 years we've been here he's never complained and there's no evidence that it's affected the quality of his crops. Must say, never thought about it until you raised the question.
Our American friends usually just spray it over their lawn or run off downhill.
As it will be human-safe pool water with very low level of bio-crud from the sand filter, I’m pretty sure it won’t hurt anything.
I do have a nice tennis court sized patch of weeds I can test it out on as it happens.
Looks like I have another plumbing project on my hands...

After some DIY plumbing and an Amazon delivery, I now have a reel of 50mm lay-flat hose which couples up to the waste pipe from the multiport valve via a firehose style QD connector.
So far, I’ve sloshed a couple of thousand litres of dirty pool water onto a nearby patch of grass and it’s the healthiest looking grass on our property.
Closing the other skimmer and sump valves once the pump is primed greatly reduces the amount of pool water going to waste without losing suction on the vacuum hose.

We have had a salt water pool for 15 years and apart from changing the cell every 3 years it has been brilliant. This year we fitted a new system for €600, it will serve a pool bigger our 10 x 5, 75,000 litre one and seems to be more efficient meaning less pump running time. The other advantage is we can backwash directly into the garden with no problems.

Unless things have changed recently here in France, salt generation pools are not acceptable to the dept of sanitation for use in multi-usage (IE Gites) pools. Only standard chlorine dosage.Vera wrote:We have had a salt water pool for 15 years and apart from changing the cell every 3 years it has been brilliant.

As the salt water pools actually generate chlorine from the added salt by electrolysis then you have a chlorine pool so whether you drain straight onto the garden would not make any difference whether salt or chlorine dosed pools.
I agree that a poorly regulated chlorine pool can be unpleasant on the eyes etc, but that is the fault of the owner/pool maintenance people not the system. Properly regulated chlorine pools (Cl and pH levels controlled.) are a joy to use.
What would Plato do ?
