It's been another great roadshow here at Warrington, it's been a great first show for Brawoliner's new micro drum and steam box. Many thanks to every one who visited.

A more recent survey indicated that the sewers were now in need of relining, which is normally a straightforward procedure for the DALROD team. However, in this instance, one particular 225 mm (9 in) diameter sewer system, which was approximately 2.8 to 3.0 metres deep, had particularly difficult access problems. The access was tricky for various reasons including that the pipeline runs below a terrace of pre-war-built houses with no rodable access points from most of the lateral connections as well as poor access to most of the gardens of each individual property which made it difficult to reopen the lateral connections subsequent to the main line lining work. In addition to the access difficulties, most of the properties comprised 3-storey buildings that had live systems which could not be shut down adding to the general operational difficulties. All of this meant that Dal Rod had to reline the sewers whilst the system was live and over-pump where flows required it to make sure that no flooding occurred in the basements of any of the 3-storey buildings during the works. This was clearly a case for a trenchless lining or 'no-dig' solution. Having examined the options it was decided that Brawoliner was best suited to the work, a system which the DALROD team had previously utilised on similar jobs.

However not all the buildings in the city are as old or as classical as the University. In the 1970s one building was constructed, now a Grade II listed building, comprising a three-storey structure. The building was designed to compliment the surroundings and as such was built with a series of soil vent and rainwater down pipes, all made of copper piping, located within the confines of the structure. Over the years since its completion the building has been subject to the usual vagaries of weather etc and in recent years these downpipes have shown signs of deterioration. In some instances the pipework was found to be leaking causing water damage within the building.
