Reducing wastage

Both water and electricity are very important to both domestic and commercial situations.

We use water to drink, cook, wash, clean, heat, cool and carry out many industrial processes.

We use electricity as a primary power source to light our homes, power items within our homes and carry out many industrial processes.

Reducing wastage

Both water and electricity are a finite resource. There is only a limited amount to be shared around, but we all demand more of both.

Utility costs are rising and we need to be able to conserve water in domestic dwellings.

Reducing wastage

Flow Reducing Valve or Pressure Reducing Valve

A pressure reducing valve helps to regulate water pressure on plumbing systems. If water pressure is too high or is fluctuating it can affect the performance and lifespan of heating and hot water systems. It can also impact on other products around the home that are fed by mains water.

Reducing wastage

Spray taps:

These are either integral or screw in

components to restrict the flow of

Water from a tap outlet. A common

Restriction is 6lts per minute.

Reducing Wastage

Low volume WC flush:

This is recommended in The Water Regulations and has been reduced
in volume over the years. Now UK toilets quite often have dual flushes
to reduce wastage.

Reduced from 2 gallons or

9lts down to a maximum of

6lts today with a part flush

of 4lts.

Reducing wastage

Regular maintenance:

This prevents the waste of water from float operated valves. These
need to shut off when the correct water level has been reached, and if they don’t water will be discharged from the over flow and wasted.

Reducing wastage

Promoting user awareness:

Informing the customer of how to use an item correctly and the
maintenance requirements of the installation can save the customer water consumption in the long run.

Simple things like:

•use a shower instead of a bath

•part fill a kettle when boiling.

Reducing wastage

Energy efficient lights:

Customers are becoming far more

cost conscious. Compared to a

conventional light bulb, one of

these bulbs only uses 30% of the

power, the other saves 30%.

Both conserve energy.

Fluorescent light bulb

Halogen bulb

Reducing wastage

Switching equipment from standby to off:

Leaving an appliance such as a TV, stereo, or laptop on standby still
uses electricity. The Energy Savings Trust states that appliance left on standby use between 5-10% and can cost a customer about £309 per year.

Reducing waste

Energy efficient equipment:

Just like buying an economical car, people need to be aware of buying efficient equipment.

Nowadays, products come with an

efficiency indicator as part of the

manufacturer’s instructions and

packages. It shows a European

Energy Label, or after January 1st 2021 a British label.
