BJECTIVE
Reduce the consumption of fresh (potable) water.
R
EQUIREMENT
Develop a water conservation plan endorsed by directorate level
management.
A
SSESSMENT
The Client shall submit a copy of the water conservation plan that is
endorsed at directorate level management.
The conservation plan shall provide details of the water conservation
measures and the credentials of the staff who are undertaking
implementation. The plan and regular review shall be integrated into
management and operations structure and have clear delegation of
responsibility for auditing and/or monitoring water consumption. The plan
shall include:
details of the channels of communication for staff at all levels, and
building users;
monitoring of consumption;
details of actions taken to reduce water consumption, including
those already completed, those in progress, and those for future
implementation; and
a quantification of the savings.
The assessment will seek to establish if mechanisms are in place to
effectively limit wastage of water, and to set targets for water saving with
an appropriate budget for upgrading the installations.

ACKGROUND
There is an increasing availability of devices and plumbing fixtures that
have demonstrated an ability to save water over the lifetime of the
system if installed and maintained properly. Flow rates can be controlled
to reduce excessive discharge at taps, faucets and showers without
detriment to the quality of water delivery. Substantial evidence shows
that the use of water-efficient plumbing fixtures conserves water [1]. A
number of studies in the U.S. have measured the impact of installing
water-efficient plumbing fixtures through sophisticated sensors, before
and after comparisons of water bills, or other means. Although the
results varied, the studies generally concluded that low-flow fixtures are
effective in saving water.
