Silt can build up within a drain, sewer or pipe when specific materials (such as sand, clay, or quartz) enter the system through drains or gutters and settle as sediment at the bottom of the pipe.

Expert Desilting and Silt Removal Services
At Metro Rod, we are proud to say that if you are experiencing issues with your drains, gullies, or sewer system, we can help. Our desilting process is undertaken by professional engineers who use state-of-the-art equipment to diagnose the issue and find a solution. By utilising CCTV drain surveys, high-pressure water jetting, and other drain cleaning techniques, our engineers can complete desilting drains and pipes to get your water flowing again in no time.
One of the best desilting solutions we use is drain jetting. Drain jetting uses water placed under high pressure to flush out a system. It can dislodge silt, blockages, and affluent, leaving your drain or sewer clean again.
What Is the Meaning of Desilting?
Silt is made up of materials like sand, dirt, and gravel that can settle in drains over time. If left untreated, these deposits can build up and cause blockages, restricting water flow and putting unnecessary strain on your drainage system. When silt mixes with sludge and other debris, it can form tough, compacted layers that worsen the problem, increasing the risk of flooding or damage to your pipes.
That’s where drain desilting comes in. This process removes the built-up silt and debris, restoring your drains to full capacity and keeping water flowing freely. Regular desilting helps prevent costly issues like backflow or pipe damage and reduces environmental risks, such as contamination from stagnant water. Staying on top of silt removal ensures your drainage system is clear, reliable, and hassle-free.

Desilting FAQ’s
How Does Silt Build Up Over Time?
How Are Drains Desilted?
There are several different ways of desilting a drain; however, the most popular method is through high-pressure drain jetting. To jet a drain, we blast water through the system under a certain amount of pressure. That water cleans the pipes and removes any silt. In other cases, we may need to vacuum the silt out using a tanker.
How Do You Prevent Silt From Building up in Pipes?
Regular drain maintenance is a fantastic way of ensuring that your drains remain healthy and silt free. At Metro Rod, our engineers can help you keep your drains silt free by conducting routine maintenance on any drains on your property to help keep them clear of any form of build-up.
How Long Does It Take To Desilt a Drain?
How long it takes to desilt a drain relies on two different factors – the size of the drain and the amount of build-up there is within the drain. That said, our goal is always to minimise disruption to your day, so we aim to conduct any desilting service as quickly and efficiently as possible.
How Much Does It Cost to Desilt a Drain?
At Metro Rod, we always aim to make our desilting service as quick and efficient as possible. That being said, the cost of desilting your drain can vary, depending on several factors, including the size of the drain and how serious the silt build-up is. To find out more about our desilting services, you can call us today on 0800 66 88 00.
What Is the Difference Between Desilting and Dredging?
Desilting and dredging are both essential for keeping drainage systems in top condition, but they tackle different challenges. Desilting is a preventative step, helping to remove lighter deposits like silt before they cause clogs. Dredging is needed for more serious build-ups, removing heavier sediments and solid waste that can collect over time. Dredging often involves specialised equipment and is used when your drains need a more thorough clean. Both services play an important role in protecting your drainage system, and the right choice will depend on the severity of the blockage.
