Our objective was to drill two 48 metre long 250mm PE pipes to be used as a gravity drain from the lake to a stream. The two pipes were to run side by side, under a large mound with a depth of 9 metres and containing a water main. Our team completed our task successfully using our JT30 machine and the lake now drains into the stream naturally without the use of an expensive diesel pump. With the help of the new drain to maintain the level of the lake this old gravel quarry is on its way back to a nature reserve. This project was carried out for our client Tarmac a CRH company.
