Y Fitting with Valve?

[menkes]

I am working on a little project to see if I can divert some grey water from our septic tank to a holding tank to be used for irrigation. What I want to do is modify a 2" drain pipe so it can drain to either the septic or the holding tank. I could put in a Y then shut off valves on each resulting line, but is that the most effective & cost efficient approach?

Thanks.

By gray water do you mean from the sink, tub and shower drains? I don't think that I would be using untreated soppy and greasy water on the lawn. Reuse water is used in many city's for irrigation but it is treated at the sewer plant first.

I see a future thread post

" My irrigation has stopped working, Pipe Restriction"?

Lawn? You must live in the city. The purpose is to irrigate clover and small brush on 3 of my acres downhill from the source. The water - yes, from the tub, shower, and sink, but not from the kitchen or laundry or toilets - will pass through two screens to eliminate any particles, then into a surge tank where it will be pumped out onto ground soil that is well suited for natural filtration.

Where I live fire danger is very real every year, and the cost of water (electricity actually since our water is from wells) is prohibitive for general irrigation. Since I have a large household, it makes sense to re-use what we can.

So back to my original question...seeming like maybe there is no alternative...?

Gray water recycling is becoming very popular these days but since most of us live within city limits, it is still prohibited because of the thought of using "dirty" water. Depending on where you reside, it is possible but it does take lots of creative designing.
