This innovative technique involves using a machine to bore holes underground, minimizing disruption to the surface. Unlike traditional excavation methods, trenchless moling requires less manpower and equipment, resulting in lower labor costs and a quicker completion time. This makes it an ideal solution for residential, commercial, and industrial projects where minimal disturbance is desired.

No, it is not safe to have lead water pipes; especially for children or pregnant women. Lead can leach into the water supply, especially in older pipes, causing contamination and potential health risks. It is recommended to replace lead pipes with safer alternatives to ensure clean and safe drinking water.
Whilst water companies in the UK have a legal obligation to replace lead pipes in their own systems, this usually ends at the boundary to private property where pipework is the responsibility of the land owner. The UK government has set a target to remove all lead pipes from the public water supply by 2040. Water companies are required to prioritize the replacement of lead pipes in areas with high concentrations of lead and to work with homeowners to replace any lead pipes on private property.
