    I don't know, the neighbour just had an email from severn trent telling him to stop building due to the sewer, I've not had anything as of yet so I'm not poking the bear over it at this moment.

    What niggles me is out of the 4 corner plots affected 3 have all been sold in the last 6 weeks and 3 different sets of solicitors have not made any mention of any easements or covenants regards the sewers, I can't imagine 3 sets of solicitors are incompetent

    Well, slight improvement on earlier, it's only a 100mm pipe, so chances are it's not ridiculously deep, and would also be easier to divert if need arose. My guess is it would be under the footpath, very unlikely (but not impossible) they've routed it through gardens, but normal practice is to put main sewers under the roads where they can be got to more easily should the need arise.

    Also typical water company map, does beg the question why the drain from your property is going diagonally upwards from Manhole 2 to 1, before going out into the road and apparently coming back on itself.... I would have expected the Builders to take the shortest route, i.e. straight out into the road, assuming they have actually indicated the correct direction of flow....

    Now we're in possession of the extra information, it does make it clearer. I suspect ST are (like a lot of people) working from home and using COVID as an excuse not to come out. I think you are being reasonable with your willingness to compromise if need be, and they need to start being more cooperative in helping you arrive at a solution.

    I'm not sure I understand severn trents fuss about it at all really, if it is in the footpath where it's been relaid then it will be 3m from the edge of my foundations and as standard practice I'd dig the foundations to the depth of the sewer so the forces that transmit at the 45 degree angles have zero effect on it.

    A pressurised sewer would frighten the **** out of me!

    Standard procedure I suspect. Try going anywhere near a HP gas main, got a rollocking once for putting a Portacabin over where the pipe ran.

    As above, a farmer near me put planning in for a development to find out there is a HP gas line under the field, and he can't build a house within 50m. Didn't leave him much field!

    Between Polegate sewage works and Hailsham S.W is a large pumped main that runs along the old railway bed. While making the journey the waste gets partly digested anerobically - so when it exits @ Hailsham works it stinks !!. Luckily I live at the opposite end of town (y)

    You'd be surprised how many dont do their homework, buy a nice shiny new house a stones throw from a sewage works that's been there for 60 odd years then start kicking up merry hell about the smell. The Site operator then has to spend a fortune on odour mitigation, and we all wonder why our water bills are going up.... :rolleyes:

    I was approached by someone at a harbour (an active fishing harbour) asking me to sign a petition so the boats couldn't work at night, as the noise of unloading disturbed her, after moving into a new build, on the harbour.

    :confused:

    At my local Sainsbury's, built well before the adjacent housing estate, some of the occupants of the housing estate complained about the frequency of the deliveries to said Sainsbury's, now there are no overnight deliveries and the aisles are busy every morning 9-10 with the racks of produce that need loading onto the shelves.

    Various new comers to the village

    {1} complained about the church bells.
    {2} complained about the smell from fertiliser being spread on the surrounding field
    {3} complained about the lack of entertainment and having to drive 7 miles to the nearest cinema

    Are you sure it is pressurised?

    I’m not too well up on the maps but isn’t ‘VC’ salt glazed clay? Purple drains private and yellow shared/ST owned. And would a pressurised sewer have manholes?

    Edit: Forget that, I didn’t read all the posts, just saw the picture.

    They can have chambers when an air admittance valve is necessary. Normally fitted at the high points in the pipe run from pump site to sewage works.
    They are normally closed when the liquid is being pumped and under pressure.

    They open to allow air into pipe when pumping stops. This allows the pipe between valve and sewage works to empty under gravity.

    The last major sewer leak in the village was the failure of an air admittance valve. It was still open when pumping started.
