Guidance on design, materials and construction

We’ve produced this guidance to reflect edition 3.1 (May 2017) of the national ‘Code of Practice for the Self-laying of Water Mains and Services – England and Wales’.

The requirements specified here should be followed as if they formed part of the Code of Practice.

If there’s any further information you’d like to see included in this guidance, please contact our self-lay programme manager, matthew.kemp@thameswater.co.uk.
