Water Conservation Techniques

Renewable Energy

Renewable Energy Renewable energy is energy generated from natural resources

such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished)

Generate carbon free energy and are also clean and pollution free

also referred to as "pollution free power" technologies

Water Treatment/Conservation

Products with the water treatment/conservation feature either increase the quality of water or reduce the amount of water used on a site.

This can be accomplished in two ways:

by physically restricting the amount of water that can pass through a fixture (showerhead, faucet, toilet) or

by recycling water that has already entered the site.

Water Efficient AppliancesAny appliance which uses

significantly less water than a standard fitting.

Such as:

Water Efficient

Appliances/ Fixtures

Waterless Urinals Resemble conventional fixtures Easily replace them Eliminate flush water supply lines Flush valves are completely eliminated No handles to touch, no sensors to install or

adjust Daily cleaning procedures are the same as

for flushed urinals.

Benefits: cost savings reducing the problem of water shortages reducing the energy required to treat water reducing the amount of water that flows into

sewers The costs of installing these products are

comparable to standard fittings.

Water saving shower heads

Shower accounts for about 30 % of the total household water consumption

A reduced shower head flow rate will reduce water consumption during bathing, without sacrificing user satisfaction

Water saving faucets

Reduced faucet flow rates can still reduce overall domestic water consumption, water heating demands, and wastewater treatment loads.

High-efficiency faucets in the bathroom

or a faucet aerator can reduce water flow by as much as 30% without significantly reducing performance.

Water saving washing machines Automatic clothes washing machines account for about 20% of

the total volume of water consumed in residents Savings in water usage for these devices may come from

different loading positions, suds-saver options, water level settings, and design.

Rainwater Harvesting A system which collects rainwater from

the roof of a building and stores it for reuse.

This reduces water requirements from

the mains supply.

Water collected is then stored in a tank, before being pumped around the building, as and when required.

This water is not suitable for drinking purposes but is used for other purposes such as flushing toilets and for washing machines.

Benefits: Reduces the demand

for treated mains water by up to 50%

Sustainable drainage

Reducing the demands on water treatment plants.

Grey water recycling Any water that has been used in a

building, except water from toilets, is called grey water.

Dish, shower, sink, and laundry water comprise 50-80% of residential 'waste' water.

This may be reused for other purposes, especially landscape irrigation.

Benefits: Lower fresh water use Groundwater recharge Plant growth Reclamation of otherwise wasted

nutrients.
