I live in a Victorian Terrace which shares a sewer (rain and foul water line) with ten other properties. My house is at the end of this run and there is a manhole cover with a turning chamber in my back garden.
After it turns the sewer then runs underneath my property before exiting into the main sewer that lies beneath the middle of the road. At the front of the property there is no visible inspection chamber or manhole. Is this unusual? I would have thought that there should be a point of entry to clear blockages where the line meets the main sewer. The only point of access is the turning chamber in my back garden which is shallow with no rodding eye.
Thames Water recently CCTVed the sewer and found what they called two 'inlets' next to each other, 12m away from the manhole in the back garden. I put this as just outside my property in the very narrow front 'garden' or possibly even under the public pavement outside my house. I am wondering what these two inlets might be (what historical purpose they may have had) and whether they may be an inspection chamber and a four air outlet. I am wondering whether to excavate to find out. My concern is that they may not be capped off properly and that there is no access here to clear blockages from ten houses.
There is a rainwater downpipe that runs down the side of the house at the front of the property and enters the ground, runs under the front garden, under the pavement and exits at the side of the road - so the two inlets are not related to this rainwater drainage as it drains into the open road at ground level and not the sewer/a drain. Any thoughts on what these two inlets might be, greatly appreciated.
