There are 3 water main replacement techniques used today including trenching.
Here at ADI Leak Detection in Buckinghamshire, we are specialists in long distance water mains replacement and installation.
We use Horizontal Directional Drilling & Moling. Each of these techniques have their own benefits and disadvantages for pipe replacement or installation.
The method we choose to use depends on different factors and challenges faced at each individual job.
We will take into account the length of pipe that needs to be replaced, the type of soil it is in, the cost of remedial works and the level of access there is to the site.
Horizontal Directional Drilling or HDD is the latest technique used to install or replace underground water main pipes. Our experienced engineers access the area using ground penetrating radar and plan a path underground avoiding any obstacles then drill a small pilot hole. Using sonde we will track the progress of the drill head to ensure it is going in the correct direction and at the right depth. Once the drill reaches the finishing point the new mains water pipe is attached and the process is reversed and the new water pipe is pulled back through the pilot hole. This is a great option for water mains that need to be replaced and are over 20 meters in length, perfect for already landscaped areas as there is very little disruption to the land and we are able to fit up to 100 meters of new water pipe in a single day!
Moling is the most cost effective way to lay a new water pipes or for water pipe replacement of less than 25 meters. Firstly, one of our engineers will dig an entry hole and exit hole in the ground to the required depth. Then a specialist piece of machinery called an impact mole, powered by a pneumatic drill will force its way to the exit hole creating a pathway in its wake. Once the mole reaches the exit hole we attach the new water mains pipe to the mole and pull it back through the newly created pathway. As only two holes need to be dug for this process your property can easily be put back to how it was originally found and often you can’t even see that work has even taken place. This is a much less disruptive method than physically digging trenches for the new pipe to be laid.
Trenching is a highly disruptive process for fitting a new water mains pipe. It involves using machinery to dig a long narrow trench the entire length of the new pipe that needs to be fitted. As you can imagine this can be a time consuming, messy process and the destruction left behind can be high. This process is best suited for areas that have yet to be landscaped, such as new build properties that are unfinished and are able to be out of action for a longer period of time.
At ADI Leak Detection our complete range of water mains replacement services and equipment are available to both domestic and commercial customers throughout Buckinghamshire, . Taking advantage of our non disruptive methods such as Horizontal Directional Drilling and moling we are able to allow commercial customers top keep their premises open while we carry out the work as only a few small holes need to be dug.
