Prepping for a greywater system

3timesbuilda · Jun 14, 2007 5:02 pm

Just spoke to our builder about changing the drainage system so that the grey water joins the sewerage water somewhere other than under the slab.

Basically short of spending in excess of $8000 to get the plumbers to "redesign" the system (in other words run the pipes parallel to the edge of the slab) there is no other option.

To me this seems like a scandal. The plumbers are saying that they don't want to take responsibility for the system unless they redsesign the whole greywater system. I just want to have the option to get a system in the future.

What does everyone else here think?

That sounds crazy!

I don't think we'll do anything with greywater initially - but when greywater recycling systems get cheaper, we'll invest in one - so would definitely like to have access to the pipes later.

Sounds like it's in the THB !!! (Too Hard Basket)

So they have priced it so you don't make life hard for them.!!!!

What is the lay of the land, (ie fall verus where the sewer mains are versus where the grey water has to fall to get it into you proposed greywater system? Where it would be.

In simplistic terms, it should ba a case of a second lot of pipes for the bathrooom, shower and laundry run to a external location where you can get at them.
Are you thinking you'll want to treat blackwater too? Personally i wouldn't and that should keep the costs down for you.

Maybe this site will help with some info.

I think 8 k is too expensive. You could request them to only place diverter (costs about 60dollars) under the sink and let one of the pipes exit the laundry from the side. in this way they do not have to make major changes to existing drainage system.

Just received quote from me3con re provision for grey water diversion in future $490! I think the breakdown would be $150 for materials and $300 for labour and variation fee.As I understand, they will be providing a small exit from the side of the laundry in addition to main sewer discharge under the trough..
Initially I thought of using shower and washbasin water for flushing too but
Aqua reviva costs 13K and I have heard that water can go 'off' smelling like rotten eggs. I have hence opted for flushmiser for toilets using rainwater(3.5K from builder) Laundry greywater for front garden-- ecodiverter or some such thing 3k... later on adding rainwater tanks for vegie garden 1-2 K.
try requesting them again.
cheers,

As stated the important thing is the ability to add it in the future. When a slab is poored, they leave a trough the size of a milk crate under the shower and bath to allow for the connections to be put it, then they fill it in. If you can get a pipe put in from that outlet to external, that would be great. I think someone actually mentioned in another thread.

Hmmm. that may be the way to go, add in a pipe that doesn't connect to anything but runs to the edge of the slab. Later I can get the plumbing both internal and external. it is not the ideal solution but seems the best option I have.

If I can find a picutre, I will post it, it will explain my strange statement.

Adrian, you've built with Metrikon too. Did you get the pipes laid the way you're suggesting? I received negative replies twice, finally I had to ask them to put the diverter and then they agreed.I still havent got a reply whether they will place rainwater inlet pipes for laundry.
i would like to know how you negotiated with them for these variations.
cheers,

Nope, I heard about it after the frame was up so it was too late. The hpoto was just showing the proximity of the troughs to the edge of the slap :cry:

How did you end up with your grey water?

Lots of plumbers and builders still think its too hard - and it is I guess until you know how it probably is
