Re: Encase sewer pre KDR and fencing near manhole 16Sep 10, 2020 5:45 pm Yes. If any part of your house/retaining walls/paths are within 2m of the sewer, then you would have to pier down past the zone of influence and concrete encase that part too. You will have to engage a water services coordinator plus a structural engineer as well and they will walk you through the process. I presume you are in Sydney and are talking about Sydney Water?

Stewie Ah! I reckon the garage on the right side might be affected too. Yes it is Sydney Water, thank you Stewie D Given your expertise on this, I am wondering if you could also help shed light on this other question I have posted here on the forum. I want to subdivide an old block in Sydney South West and that would obviously require full service separation. One of the proposed lots could easily make use of the existing junction but the other lot would need to have a new one installed. From DYBD, a cast iron concrete lined sewer pipe (CICL) is passing through the front of the lot, I checked through Sydney Water's information booklet and they didnt seem to provide much info unless for PVC and VC lines. Can their S1/S2 contractor easily cut a junction into a CICL line? What would be the cost implication compared to PVC or VC? Are their other alternatives looking at the attached photos?

I was under the impression that they used fibreglass and other types of resin to line them not concrete. I have no idea on costs either but I'd imagine it would be more expensive as there are lots of earthenware to PVC and PVC to PVC adapters of all types and sizes. Cut the pipe and install one and away you go. To cut into a concrete lined or otherwise would require a bit more. We are having our point of discharge changed in the coming months as part of our DA but we'll be doing that at the same time as concrete encasing two areas because of retaining walls over the top.

Stewie Thanks so much Stewie! Valuable info. DA has been with the council for a while now and they have not said anything regarding this yet despite loads of other issues they have asked us to address. If you have any WSC you’d like to recommend, would appreciate it. One last question, the estimate for encasing you posted was from 2014, has that by any chance changed? I’m always confused by the concept of lineal meters, any chance you know what would the Estimated cost translate to for a standard double garage Driveway? Re: Encase sewer pre KDR and fencing near manhole 20Sep 12, 2020 6:51 am With our council I knew from past experiences that they would require us to get a stamp on the plans from Sydney Water before lodging the DA. Now they want you to go onto Sydney Waters website and do a water check ( Sydney Water Tap in Assessment ). Any red flags and they will get you to engage a WSC who need a peg-out to ascertain the exact location and depth of the sewer and will then require you to get structural drawings in regard to your driveway similar to my drawings above. Only then after everything has been approved from Sydney Water and stamped as such from the WSC would you be able to lodge the plans with the council. I'm surprised your council haven't asked for this already as it could mean a delay of several months in approving your DA. Your draftee or architect should have known this! I'm pretty sure the cost would be now around $1,500 per lineal m but it will depend on a few factors - ease of access to the area in question, depth of your sewer, slope of the land etc. Just add up your total lineal metres x $1,500 and you should be in the ballpark. If your driveway is 5m wide for instance, add just a little more for clearance say to 5.5m, x $1,500 = $7,500 MGP is who we used https://www.mgp.com.au/services/sydney- ... structure/ and found them to be very good. They do mostly the Northern beaches but with everything being online these days I'm sure it would be just as easy for them to do your job as it would a local area. Stewie You might be able to apply to divert the sewer at your expense. In NSW you would contact a Water services co-ordinator and they would give you advice as to whether or not… 1 16336 Hi everyone, Looking for some advise.
