Purpose
The purpose of this qualification is to provide the construction industry with individuals who
have knowledge and practical skills to design and certify drainage systems.
The qualification is a prerequisite to registration with the Plumbers, Gasfitters and

standards. A certifying drainlayer is responsible for ensuring both their own work, and the
work of anyone they supervise is done competently.
This qualification recognises a range of design, management and supervision
competencies in the drainlaying trade. Holders of this qualification are able to design
drainage systems, manage and coordinate with other building services the installation of
drainage systems, supervise drainlaying staff, access and apply relevant legislation, apply
conservation and environmentally considerate processes in the design of drainage
systems, and cost jobs for drainage systems.
This qualification leads on from the National Certificate in Drainlaying (Installation)
(Level 4) [Ref: 0077].
