NSTALLATIONS
Section 14(3) of the Waterworks Ordinance (Chapter 102) empowers the
Water Authority to prescribe the manner of construction or installation
and the nature, size and quality of the pipes and fittings of an inside
service or fire service for water supplies. All plumbing proposals for
inside service and fire service are therefore subject to the approval of the
Water Authority [5]. The Hong Kong Waterworks Standard Requirements
is a set of normal requirements which are applicable to the installation of
inside service and fire service in addition to the requirements that are set
out in Schedule 2 of the Waterworks Regulations (Chapter 102) or
modified under Regulation 25(1). Where necessary, additional
requirements may also be imposed on an individual application for water
supply, depending on the nature and type of the plumbing installations.

AMPLING
Part 6 of ISO 5667 [2] establishes detailed principles to be applied to the
design of sampling programmes, to sampling techniques and to the
handling and preservation of samples of drinking water and water used
for food and beverage processing (drinking water). It is important that the
sampling purpose be defined as accurately as possible and that the
measurements provide the required information in the most efficient and
statistically representative manner.
