Insufficient fall on sewer
Discussion

Does it only serve the two properties?
Touch and go really, bit too slack at 100mm really, but not enough flow to keep a 150 pipe flowing sufficiently.
Building Reg's would allow the 150mm with about 3 WCs in so I'd be happy with it if private.
But SFA6th and 7th are quite specific in what they allo.
If it's only 2 houses Could you guesstimate the amount of toilets, wash hand basins, kitchen sinks, baths, dishwashers and showers in and I'll do the maths on Monday and get back to you.
If it's more houses than 2 just go with the 150mm.

Ours will go from a one toilet one bathroom arrangement (not changed layout since 1928) to 3 toilets, 2 showers, one bath, 5 sinks (includes kitchen + utility), dishwasher, washing machine.
Neighbours have one downstairs toilet and one bathroom upstairs. So i'd hazard a guess at 3 sinks, 1 shower, 1 bath, 2 toilets. Washing machine and dishwasher.
PS: I could have paid you to do my submission! oh well.

What's the reasoning behind that? Plenty of plastic options in SFA7 that can be used. Do Thames have their own addendum?
I guess it depend show you read item 17:https://developers.thameswater.co.uk/-/media/site-...
It's not quite comparable as a diversion is a S185 rather than a 106 and generally would be designed as a new sewer. I'd expect masonry, concrete or plastic to be acceptable in this instance, you'd probably even get away with plastic pipe instead of clay for the ne length unless you get a d
head inspector.
Think my team submitted a new S104 to Thames on Friday so will have a look at those details and give more info.

Leave it with me, I'll do you something you can submit.
Very very kind sir. I'll check with my architect, but I think he might have already submitted it.Would be very useful to gauge feedback if things get refused etc. I'm hoping it will all be ok, builder and architect are both confident.

TW just have their own agenda on what they will accept in manholes, a couple of builders have been caught out by it, putting in what they considered to be a suitable answer only to have to remove them.It's just a heads up from recent continued findings let's hope your experience is different.

OP, if you send me a PM I'll fling you the calcs, I'd go with the pipe at 100mm as a first request to Thames, it's pretty much a like for like diversion so should be acceptable with the flows I've got for you.
hi - i did send you a PM, just double checking to see if you got it.AlmostUseful said:
I did not! And then I did...
Turns out that when I got my new phone I only put one of my email addresses into the mail app so don't get notifications from here! Will send you a note tomorrow now I've found it.
Am just resurfacing this thread. Have sent you a PM sir.Turns out that when I got my new phone I only put one of my email addresses into the mail app so don't get notifications from here! Will send you a note tomorrow now I've found it.
