Bypass pumping

Over the years, Aarsleff Pipe Technologies has developed into an international group that executes No-Dig renewal projects in many countries. No matter which renewal job we are dealing with, considerations about bypass pumping are always part of the planning phase. It has always been like that at Aarsleff Pipe Technologies as we consider bypass pumping as an integrated part of a common renewal process.

Today, we have the most advanced equipment for bypass pumping on the market. We have developed much of the equipment ourselves concurrently with developing new methods and techniques for No-Dig renewal.

We always customise bypass pumping solutions for the individual jobs. Large or small. We do not commit ourselves to a solution before we know each individual job thoroughly. Generally, difficult access and working conditions are the greatest challenge when establishing bypass pumping. Particularly, when executing big jobs where we often have to use large generators to be able to generate power for the huge pumps that we have. In fact, we have so many pumps that we rent them out to a great extent. 

When we are pumping, we use both soft hoses and large PE pipes that we weld together. The development in the field means that in connection with most renewal projects, we have a number of alternatives to choose from when establishing bypass pumping. For example, we bury hoses and pipes or lead them across roads. In some cases, we even leave hoses and pipes with wastewater in a watercourse. In case of moderate amounts of water, we are also able to establish hose bridges that even let city buses pass. We consider it very important to cause as little inconvenience to the surroundings as possible.
