Objective The partnership will demonstrate a localised sewer patch repair system with UV-cured-in-place-patches systems, which uses ultra-violet to cure factory-prepared liners. The technology will be demonstrated in close cooperation with the largest Water Services Company in the UK.Leaking sewers have long been suspected as an important source of groundwater contamination, particularly in urban areas. The pollution threat posed to groundwater be sewage and sewerage systems has been recognised for many years.Short, part-liner systems (usually referred to as patch liners or patches) have been developed. These can provide a highly cost-effective means of restoring the structural integrity of sewers and/or resolve infiltration and exfiltration.Groundwater is a major source of potable water in large parts of the European Union. In England and Wales it accounts for around 30 % of all water supply and is also widely used for industrial, agricultural, domestic and other purposes. Recently several causes of the deterioration of groundwater have been studied. Leaking sewers have long been suspected as an important source of groundwater contamination, particularly in urban areas. The pollution threat posed to groundwater by sewage and sewerage systems has been recognised for many years. Replacement of existing defective sewer networks is expensive, particularly in urban areas. It is however been recognised that the use of full length liners can be wasteful of resources, since in many cases the defect to be treated is localised within a individual sewer length. As a consequence, short, part-liner systems (usually referred to as patch liners or patches) have been developed. These can provide a higly cost-effective means of restoring the structural integrity of sewers and/or resolve infiltration and exfiltration.Key problems of the existing patch repair systems:- it is difficult to ensure consistent product quality on site under all likely environmental conditions- significant risk of spillage of uncured resin materials on site, and consequently damage to the environment- slow, expensive and inflexible process- the patch materials have to be 'wetted-out' on site with the uncured resin which inter alia results in high costs of energy and risks of styrene emissions.The partnership will demonstrate a localised sewer patch repair system with UV-cured-in-place-patches systems, which uses ultra-violet to cure factory-prepared liners. The technology will be demonstrated in close cooperation with a Water Services Company.
