Semfa operates within the water and sewer network to concentrate upon rehabilitation of the system to domestic and industrial users.

Water is a valued resource and the aging networks constantly collapse and have major breakdowns and leaks .

The Semfa approach is to upgrade the network where possible by using the existing pipes and systems, rehabilitating them using a range of technologies and options to ensure cost effectiveness and to minimise the disruption to the locality.

Semfa will offer full specification and project management services, contracting and supervision , training for local team development, supply of all technology and equipment

Activities include the following:

• Advanced leak detection systems based on tracker ball technology
• Pipe inspection equipment and services for all types of pipes and assets that are typical to the municipality market place
• Specifically designed pipeline pigging systems for utility pipes
• Pipeline and equipment corrosion inspection and introduction of Cathodic protection where required
• Full Asset Integrity Management programs and system to monitor and control the pipe systems, equipment and services
• Complete range of trenchless rehabilitation technology , equipment and systems to suit various application requirements such as pipe bursting, slip lining and tight fit ( Swagelining) lining systems
• High specification PE and co-extruded pipes for water and sewer applications as well as for gas pipes. These can be for lining as well as for stand alone systems
• Novel replacement man hole covers to avoid the problems of cast iron cover theft
• Introduction of specialist component suppliers such as extruded specialist pipes and fittings to complement the rehabilitation technology being introduced
• Epoxy and urethane epoxy resin systems for coating and repairing large sewer rooms, pipe-lines and manholes which can dry in wet conditions, thus allowing sewer operations to be minimally affected
• All standard and specialist equipment for horizontal drilling, pipe bursting and other utility activities
