Chapter 9 Sanitation systems

Part 5 of this standard gives information that should be followed when installing
and maintaining waste water gravity drainage systems, as well as the materials
that can be used.

BS 8000 Part 13: 1989: Workmanship on building
sites. Code of practice for above ground drainage and
sanitary appliances

This provides recommendations on basic workmanship, and covers tasks that are
carried out in relation to above-ground drainage and sanitary appliance installation.

The Water Supply (Water Fittings) Regulations 1999

This is not strictly relevant with regard to sanitation, but sanitary appliances
require hot and cold water supplies, and appliances are used in connection with
foul and waste water. Consequently, the Water Regulations must be consulted
to guard against backflow of contaminated water.
