Ensuring that these elements of a project can be delivered means planning ahead and mitigating any future problems, says Steve Jeffries, product manager – foul water systems at Wavin UK


THE DEAL ON DRAINAGE


Tree root ingress in pipes is a common issue that can massively affect below ground drainage in the long-term. BMJ investigates one solution.


“Root ingress is a key example of this. It is a problem that occurs when trees are planted close to below ground pipework, and is a hidden issue that can eventually lead to blocked pipes. As roots infiltrate drainage networks in search of water, oxygen and nutrients, they cause debris like tissue paper, wipes and fats to become stuck. This ultimately leads to waste flowing more slowly or stopping altogether,” he says. Traditional methods of combatting root ingress are time-consuming, disruptive, and extremely costly for those responsible for managing pipework. Jeffries explains that there are three main ways to resolve the
