A critical means of removing surface and subsurface water from in and around buildings of all types, drainage has developed significantly over the years. Innovations like the linear drain and the manifold drain have not only provided specifiers with effective ways to prevent flooding, inundation, and subsoil degradation, but also opened up fresh design possibilities.

However, those involved in specifying and installing drainage system need to be careful. The use of unsuitable or incorrectly installed systems increases the chances of damaging not just properties and their contents but also associated utilities like gas and electricity. Moreover, non-compliant plumbing products can leave buildings uninsured and result in financial grieve for builders and property owners.

So, what are the relevant regulatory requirements to follow when specifying drainage? What practical considerations should specifiers be aware of when taking on this task, and what are some of the most impressive design solutions available right now?
