ABSTRACT
Architects typically design services for small buildings, involving plumbers and electricians for detailed expertise on-site; as services have become more sophisticated, so have the regulations controlling their installation in buildings. Covers are manufactured in steel and ductile iron. Covers may have single or double seals, plain or recessed tops, and be multiple leaf or continuous for ducting. Alternative features include chambered keyholes, handlift recesses and locking screws. Sustainable Urban Drainage Systems (SUDS) applies sustainability to surface water management to minimise the impacts from development on the quantity and quality of runoff, and maximise amenity and biodiversity opportunities. The Water Supply (Water Fittings) Regulations 1999 supersede the Water Supply Byelaws. The regulations apply only to fittings supplied with water by a Water Undertaker (WU). Contractors approved by the WU must issue certificates to clients stating that the work complies with the regulations. Water for domestic use or food purposes must not be contaminated by materials such as lead and bitumen.
