Re: Broken sewage pipes across our property 7Mar 14, 2014 8:17 am Thanks, Liliana I think we have a similar thing here in NSW - before we built and also after we built (for our own landscaping purposes), we requested all pipes for all utilities (gas, water, etc.) and I think it could have been via the Dial before you dig site.

Did you press home the point properly? Sewers only stink when they are broken. You could get a smoke machine or somethign and put a bit of smoke down there yourself if you like, see if it comes up anywhere. Pipes are laid in straight sections, forget about your fruit tree. Main sewer lines are generally 1400mm or more deeper in SE Qld, Sydney I dont know. Re: Broken sewage pipes across our property 10Mar 15, 2014 10:34 am Thanks guys. I did give them an initial call ... long story short - I will call them to log a job when we have the time to be at home as this is considered "emergency"! Funny you should mention the stink - but as you can see from my previous posts, they did ignore it. I guess a good thing is that they could see that job in their system! And what do you mean forget about the tree?? Are the pipes really that deep??? Strange, as the person I talked to asked me if there is any soil subisidence over the pipe - as if the land that deep down could have moved so much so that the top sections of the pipe have collapsed - otherwise, I cannot imagine how can soil visibly subside unless something (ie. a shallow pipe) collapses considerably deep down in ground. If the pipe is only cracked, I can imagine it just leaks, but the soil around it should still be compacted enough (at that depth!!) so it doesn't really show on the very surface. Mind you, there is close to zero foot and other traffic in our yard! On the other hand, the cracks must be so prominent if the "stuff" is "fertilising" our grass to go visibly greener and higher all along the line!!

A longer pipe run 'might' impact on the available slope. Is it 60cm depth difference over 1m of length of pipe??? so if I start with 1m of pipe burried at 1m depth, the pipe would be only 40cm deep at the end of the 1m?

Re: Broken sewage pipes across our property 12Mar 15, 2014 10:44 am Don't talk in cm; no-one in the building industry uses them, it is always m and mm. Sewer 1:60 = 1m rise per 60m run of pipe = 100mm rise per 6m run of pipe = 16mm rise per 1m run of pipe Stormwater 1:100 = 1m rise per 100m run of pipe = 60mm rise per 6m run of pipe = 10mm rise per 1m run of pipe Stewie Re: Broken sewage pipes across our property 13Mar 15, 2014 11:28 am Lex Are the pipes really that deep???

If the pipe is only cracked, I can imagine it just leaks, but the soil around it should still be compacted enough (at that depth!!) so it doesn't really show on the very surface. You would be surprised at how much the ground can move. Soils are either reactive or dispersive. Reactive (clay) soil will rise and fall with increasing or decreasing sub soil moisture content and are a prime cause of house cracking and foundation subsidence. Dispersive soils can break down and seemingly 'melt away' when in contact with water. It is not uncommon for a broken pipe to create a large cavity in dispersive soil that can open up and consume part or all of a house, road or whatever else may be above it. 3in1 Supadiverta.

Re: Broken sewage pipes across our property 14Mar 15, 2014 11:34 am Just a couple of clarifications Generally public sewer lines serving properties are at least 1m deep (this allows the house pipes to be laid on a reasonable gradientnto reach the sewer) but can be 3-5m deep. Sewers serving large developments can be much deeper. The gradient of sewers depends on the diameter (larger pipes can have gradients of 1:100, 1:200, or even flatter) Sewers are designed to achieve a minimum velocity of flow rather than a particular gradient. I aim for a target velocity of 1m/sec. The Harder You Try - the Luckier You Get !

Re: Broken sewage pipes across our property 17Mar 15, 2014 6:16 pm ooooohhh, where do I start ... I guess is a good point ... I did come across something else today - relining. But they need to dig a really big hole at the start and end points ... and that most likely means taking the fence down as well, since the neighbour's little lid is quite close to the fence (assuming all of this actually will be fixed, and fixed properly). The end point will need lots of excavation becuase that's where our own pipe joins the common pipe and then it runs into the access hole. BIG job (: And all the turf ruined. Who pays for that!?!?

There are all sorts of Relining one method used is Cured in Place Pipe (CIPP) which is quite common and requires little or no excavation. This is a link to one company (http://www.insituform.com/Water-Wastewa ... mCIPP.aspx) you will find a video on the top right of the page. There are several variations of this method offered b different companies. The Harder You Try - the Luckier You Get !
