There's a new estate being built by a large builder just up the road from me.

One of my neighbours is interested in buying one of the new builds. But, despite a number of houses already occupied, the builder still hasn't connected to the main sewer. At the moment the builder is paying for the drains to be cleared each day by tanker. This has all set alarm bells ringing with my neighbour.

We've looked at the plans submitted to the council and found the proposed drain connection. It is to be on the other side of an existing road that the new estate accesses. But, what puzzles me is this.

The main sewer is 4m below the road. The new estate is about that below the road as there is quite a steep access road going down to new estate from the existing road. Therefore, the sewers will have to be connected 4m below the road. I can only think they'll have to

close the road,
dig a trench 4m deep across the width of the road,
connect to the existing sewer and then
fill in the trench.

All in all, a pretty costly exercise. Or, am I missing something obvious?

They could probably tunnel or 'mole' under the road.
Or they might dig a shallower trench and install a pump.

They could be held up waiting for their drainage connection design to be accepted, or it may be that the water authority has insufficient capacity in the network..
either way, tankering it out won’t be cheap.

They would need a certain drop for it to drain properly though, right? Maybe the penny has dropped that it won't work laugh

There are new estates going up near me. We already have issues with sewerage and drainage capacity. Heavy wet weather overloads the system, sewerage comes up in fields and gardens. Local overflow tanks often need to be emptied by tanker. There is not enough sewer capacity for the existing houses

Yet still permission is being given for new large housing developments on fields and farm land, concerns from existing residents are ignored or brushed under the carpet. Impact reports are doctored to favour the developers/council.

Does the developer need to spend a lot of pennies to allow the residents to spend a penny?

The new estates will most likely have SUDs ponds to avoid overloading the network in heavy rain.

Possibly pennies will be spent on a pump. Cost of maintaining said pump will be covered by the residents forever more.

They'll need a SuDs lake for one of the estates, the field they're building on is under water most of the winter.

Likely a pumping station, waiting approval (as mentioned)... reminds me of one done about 25 years ago ( redface ) and the words 'cordon sanitaire' have never been forgotten, basically when there is no fan to hit there has to be a suitable stand off distance if it all goes wrong...

Whilst the memory is working... on another site, the main foul drain was in the central reservation of the A4540 (Birmingham ring road) and 5m deep. There was no way that road was being closed. So, the Council approved a 'timber heading', basically an old school dig down and tunnel (think WW2 escape..!)

Whilst I did look down the 5m deep hole, there was no way I was going down to inspect the final connection smile

Developers don't really care.

Last new build estate I lived on was all pumped in and out.

If the power went out it tripped the water pumps coming in, meaning they had to come out to restart the pumps but as it was underground needed a 2 man team. Whcih they never sent in the beginning and we had to wait hours for them to come.

They then had 4 pumps around the estate to pump it all out. Do you think they put in redundancy? If one failed it would flow to the next pumping station?

No they didn't, The last year I was there the accounts said it was £55k in tankers. £1,500 a day until the 1 pump was fixed.

The developers went bust and nothing could be pinned on them.

Tell your neighbour to run a mile.

Just found out the builder has never made an application to the water company for connection to the main sewer. I find this strange as the site was started nearly 3 years ago and the first completed purchases were over a year ago.

I think my neighbour has got the message, "run Forest run" and look elsewhere.
