Project Appreciation and Objectives
The Portfolio project CP371 - New Inspection Methods of Sewage Rising Mains, which gained the support of seven Water Utilities, has successfully identified and tested potential techniques for surveying and assessing the condition of metallic or plastic rising mains.
The next phase for the project is to assess the techniques in a series of trials which will determine the performance of the prototype inspection tools in live rising mains. The project will then, for the successful systems, develop a business plan for future implementation and exploitation by the project participants.
Trials will be undertaken at agreed locations in participants networks. We would seek to target sites where problems are believed to exist and would seek the involvement of all participants.
Benefits to Clients
Assessment of cost and effectiveness of new inspection techniques for rising mains leading to:
- Reduced bursts in rising mains.
- Reduced pollution incidents.
- Reduced disruption and cost of repair.
- Develop inspection specification including site data collection; cost data collation; performance indicators and likely scenarios.
- Develop scoring/ranking methodology to compare the advantages and disadvantages of the techniques agreed.
- Analyse locations proposed by participants.
- Carry out trials.
- Review costs & performance.
- Liaise with participants to develop exploitation plan and implementation programme.
- Rising mains inspection specification for successful technique/s.
- Case studies of inspection of selected participants' rising mains.
- Exploitation plan and implementation programme.
- Dissemination workshop.
