Board sewer right through the middle - Duplex construction

Hi everyone,

Looking for suggestions as I am looking to buy this property for duplex construction. As you can see sewer is running through the middle.

How much $$ it will add to construction cost in order to overcome this easement?

Property is in Sydney.

Dimensions:
15.01 / 22.05 X 49.91 / 37.34

 

Normally, you'd have to dig up the sewer line and encase it in concrete - so it becomes virtually maintenance free.
Cost will depend on how deep the sewer line is. You can find this out by contacting the relevant holder of all the sewer line plans in your suburb. If you contact council, they will tell you who it is you need to call.

 

You can see the depth on the plan. Assuming an even slope it is about 1.2 metres down. so no underground parking.

 

A while ago I was told its like 10-15k to encase it. Best to talk to a water servicing co ordinator. You will need to eventually to organise the s73

 

In Vic you wouldn't be permitted to build habitable rooms over a sewer main - maybe check that with your Water/sewer Authority first?

 

As a word of caution please do all the homework you can to work out the options. I had to build an over engineered tunnel over mine to build over it and it cost about $100k for 15m.

 

You had to build a tunnel? that's intense, any pictures?

 

It is only 150mm clay pipes so most probably a branch to pick up 2 or 3 houses. Sewer mains are usually somewhat larger.

 

There were no lights in there, the photos were too dark.

 

Is @bob shovel still around? He's handy for sewer talk

 

Some clever design work could address the site since the sewer is in centre of the lot. Two staggered sections with carport over sewer etc and driveway to the rear lot. OK you may have to accept the driveway can be dug etc. Town planner for advice.
