Construction Sites

Construction sites can be made water efficient by implementing a few simple measures.

1. Appoint a Water Controller

A water controller should manage water conservation at the worksite by adopting the following practices:

To sign up for Water Efficiency Manager Course to equip with skills and knowledge on water management.
To carry out water audits and monitor the water consumption in various areas of water usage within the premises.
To install private water meters for different areas of water usage and take meter readings regularly, i.e. daily or weekly.
To inspect the water reticulation system for leaks and to promptly repair any leaks found. Fortnightly checks are recommended.
To co-ordinate and oversee water conservation initiatives, educate workers/employees on the need to conserve water through pre-work briefings, talks, discussions, publicity materials, etc.
To liaise with PUB officers on matters pertaining to water conservation.

Toilets/Washrooms

Mandatory Measures

All water fittings such as taps, flushing cisterns, urinals and urinal flush valves installed must be labelled with at least one or more ticks under MWELS.
Install self-closing delayed action taps at all wash basins and shower points.
Install constant flow regulators at all wash basin mixers, shower mixers and bib taps

Water Efficient Measures

Adopt water efficient flow rates.
Install water efficient labelled fittings with ‘excellent’ ratings.
Install water efficient labelled dual flush low capacity flushing cistern which uses only 4.5 litres or less for full flush and 3 litres or less for low flush.
Use low flush for flushing of liquid waste.
Install waterless urinals.
Reduce flush volume of urinals to 0.5 litres per flush.
Do not allow toilet cisterns to overflow.
Do not use the toilet’s water closet suite as a trash basket.

Kitchens/ Cooking area

Mandatory Measures

Install constant flow regulators at all sink taps, mixers and bib taps.

Water Efficient Measures

Adopt water efficient flow rates.
Install water efficient labelled fittings with ‘excellent’ ratings.
Wash vegetables and dishes in a filled sink instead of running taps.
Do not thaw frozen food or melt ice under running water.
Use a low flow rinser for washing of dishes.

Canteens

Mandatory Measures

Install self-closing delayed action taps at all wash basins and wash troughs.

Water Efficient Measures

Adopt water efficient flow rates.
Install water efficient labelled fittings with ‘excellent’ ratings.

Other Areas

Wash your floors using a mop and bucket instead of hose.
If a hose is used, fix a spring loaded nozzle to the hose.
Advise the cleaners/workers to conserve water at all times during cleaning activities.
Use non-potable water for washing of vehicles at the vehicle washing area wherever possible and recycle the used water.
An earth removal facility for the vehicles should be installed to remove the earth from the tyres before washing commences.

Note: Constant flow regulators are not required where water pressure at the fitting is less than 1 bar. As a guide, these regulators need to be installed only where the static water pressure at the fitting exceeds 1.5 bar.
