I noticed that my basement floor was constantly wet and the concrete floor sloped, near the lowest point i noticed that someone had cemented a slab on top of the floor, i removed this slab and it was full of water, i must have removed at least 10 litres, i came back after a couple of days and it had water again, hadn't been raining too much, i spoke to a mate whos a builder and he informed me that its most likely a water table, my property is like a cottage, i decided that i should remove the existing floor and insulate the floor and lay fresh concrete, whilst excavating i came across a pipe that appears to be a drainage pipe, this pipe is not far from where the water table was and is in line with my outside sewer pipe. i wanted to know if this pipe is still active, could i get someone to attach a sink/wash room etc to it long term , also the pipe is moving/spinning does this mean its broken, i have attached some pics and hope someone can help. also it appears to be angled towards the basement and piece which accidentally broke was positioned towards the water table. there is no smell etc and the water table is fresh water. hope the above makes sense,thanks
