We wanted to confirm the exact depth of our rain water 100mm pipework that goes off to the main soak-away module. So after lunch, we dug down over beside the garage at the end of the Swimming Lane and went down until we found the bottom of the currently terminated pipe.
Using our laser site measuring machine and siting pole, we got a measurement of 2300 mm on the pole (using the laser detection unit) which translates to 1.3 metres below ground level. So this means that our rain water connection from the filtration unit for dealing with all our water off our roofs, can go as deep as 1.3 metres. This is good as it gives us more options in the design of the filtration module.
