MC & BRAWOLINER AIDS COMPLETION OF CHALLENGING FRESH WATER PIPE REHABILITATION

Sewer lining specialist DALROD Cambridgeshire was recently involved in a technically challenging project to keep water flowing to a major cement works in Essex, UK.  The site is part of an industrial development in the mined out area of what is still elsewhere a working quarry site, investigations showed that the pipes which carried away fresh water between to two lakes was in need of rehabilitation. However, the fact that the site was industrialised with other operations as well as the cement mixing works, meant that operating conditions for any rehabilitation works would be far from easy.

The client expressly demanded that the rehabilitation be completed in a set timeframe with all traffic management being undertaken by the contractor and most of all that not only during the rehabilitation works but subsequently there should be no pollution created by the products used to complete the works.

UNIVERSITY OF EAST ANGLIA – SEWER CLEANING AND LINING PROJECT WITH MC BUILDING CHEMICALS

As part of a corridor link and long term maintenance project, Norwich-based utility consultant Kier Eastern (part of the Kier Group) recently undertook a programme of sewer cleaning and lining work on behalf of University of East Anglia (UEA), under the direction of Tim French. The contract to complete the necessary work was awarded to Dyno-Rod of Mahoney Green, Rackheath, Norwich, with lead project engineers J Vaughan and S Plane. The work was to be undertaken beneath the Sainsbury Centre for Visual Arts, part of UEA, a prestigious and well known building in Norwich and comprised the rehabilitation of existing cast iron pipe work, which was in a poor condition and in many locations, badly pitted and corroded. Dyno-Rod advised that the most sensible and practical solution would be to Dyno-Line the existing drainage pipe. The works were undertaken as part of the overall improvement and refurbishment of the Sainsbury Centre. The work would result in a new pipe within the old damaged pipe, which would be resilient to ground movement, impervious to leaks or root penetration, and which offers minimal cross-sectional loss (and therefore carrying capacity) whilst increasing hydraulic efficiency. The lining is also guaranteed for 15 years.
