Network Construction Operations (NCO) Conversion Gas to Water Main Layer


The CABWI Level 2 Diploma in Network Construction operations (Water) – Main Layer allows the leaner to demonstrate the skills and knowledge required by main layers working in the water industry, whose role it is to install water mains on the distribution network.

This competence-based qualification covers the underpinning knowledge and practical skills required to install water mains on the distribution network. The qualification covers the technical network construction skills required for main layer, including health, safety and hygiene, and also includes requirements relating to working effectively and maintaining effective working relationships. Learners must produce workplace evidence to show that they can meet the assessment requirements consistently over time.


2 days (8 hours per day) – classroom/practical training.

Suitable For

The qualification can be used to up-skill existing staff. It is also one of the Level 2 qualifications that may be taken by apprentices working on the SASE apprenticeship framework for The Water Industry.


There are no entry requirements for this qualification. However, as there is a requirement for the learners to provide evidence from workplace activities, the learner must be working in the water industry and undertaking main laying activities on a regular basis.
