Open Trench Method
This method is predominately used when other utilities are in the vicinity of the proposed route. The main is installed by excavating a trench with the appropriate sized excavator depending on surface types and pipe diameters, the main is then laid, chlorinated and pressure tested before the new connections take place, once the connections have been carried out the work area can be reinstated.
This method is used when it is possible to down size the existing pipe, the existing section of main will be cut out at either end, the main will then be cleaned and the new main pulled through with the use of a winch, the main is then chlorinated and pressure tested before the new connections take place, once the connections have been carried out the work area can be reinstated.
Case StudiesThe above works were carried out at Morpeth County Hall on behalf of Northumberland Council, following a leak detection survey a 100m section of 90mm HPPE was installed, 90m were inserted through the existing 150mm ductile iron main and 10m of open trench were carried out as we were unable to expose the bend due to a camera column which had been constructed over the main. The main was chlorinated and pressure tested before been put into commission.
