Thread: Toilet for shed

2nd hand porta loo

or one of those camp loo's

G'day. My shed is 50 metres from the house and 65 metres from the sewer line that runs to the house. When I had the shed slab poured, I looked into all the options for a dunny in the shed and it was cheaper to trench and run sewer pipe as well as being more convienient. cost was $600 for the complete dunny including trenching and hookup.

Run shower and dunny to a small sump (less than 300 litres) close by. Fit the sump with a submersible trash pump from Grundfos or Davey (not just any old submersible!!! It must be a trash pump!) and pump from there to your normal septic/sewer using 2" rural grade poly.

Had a very similar setup on a past residence...worked a treat. Make sure you run a vent pipe/stack on the sump though!

And pray it never dies on you, fixing it would not be a fun job!

You can buy the sewer pumps and tank as a set, usually sized according to the size of the installation, they arent that cheap, the pumps cost a small fortune then theres the installation of pipe work, which will be either 40mm or 50mm pressure grade pvc to the nearest sewer point. If you can do without the shower you can get a small macerator which simply has a pan collar that slips over the back of the pan and screws to the floor. Its a little smaller than an esky, has the pump and all the gear in it already and all you need to do is run your pressure pipe to the sewer. A much simpler and cheaper alternative in my mind. Bear in mind for a shower etc it could involve saw cutting the slab, getting your drainage points in, hot and cold water etc, but in saying that I dont know the layout etc. of your shed.

I have a similar situation but I have decided to use the trees and bushes near my shed site for the dunny just like the wombats, roos and other wild life do.

Anything substantial will involve a 100m walk back to the house.

Waterless composting toilet and plant a lemon tree to handle the shower water.

Would this sort of pump be suitable? See the link at eBay.

-------I just read the write up for the pump on eBay, and it says down the bottom that it should not be used for toilet water.

Whats involved in getting the pipe into the septic tank? My tank is covered over in dirt & a garden and have never had to dig it up before so don't really know what it looks like. Is it a simple enough job to get the pipe into the tank?

Open tank

insert pipe

close tank....

Couldnt resist that one...

So how are you going to close the tank cover with the pipe now sticking in the inlet?

Cut the end off so it wont stick out.....

It's not sticking out, it's sticking in I don't think you know what I am talking about, but imagine opening the lid on a bottle of water, putting your finger in the hole, and now trying to close the lid.

I reckon you should call a plumber.
