Dave was quickly ready to head down so he headed down to check the water levels while everyone else got ready to go down. He was met coming up the ladder on his way out. He reported that despite mostly dry weather in the last week, the level had dropped about an inch, it was still extremely unpleasant level and the area Estelle had been digging 2 weeks earlier was under water, only high level digging was available. It was decided that there was no point in the unpleasantness of digging in those conditions and that we should go to the pub and discuss planning what we do next – while the water may slowly drop again over the coming weeks, it is unlikely to get to a point where it is where it was before the rains of the 8^th August and if we want to try and dig more through the winter, we need to get back to pumping

Plans in the pub involve looking at acquiring 1 or most likely 2 110v pumps as safer than 240v, we will need a transformer, but between us may have ones that could come and go each week if needs be. We need to look to secure the pipe at the end as currently it is crossing the path and effectively in the way and it needs to be set up to allow a bit of future proofing on length to pump a bit further ahead than we are now. We need to decide if we want to split the level and pump to a barrel which could be located by the outside end of the railway line and then a 2^nd pump would pump up to surface and towards the pond. We also need to look to check the electric cable that is currently in the cave and make sure it is safe and sound. Will look to ask Mark or Ben to come over at some point soon and take a look for us. We will ask around re 2^nd hand pumps, but also look to price up new from online, they need to be able to cope with the sludge and also the height.
