Basix Certificate for Swimming pools & Outdoor Spas

As from 1st October 2006, all new Development Applications in New South Wales for a swimming pool with a capacity of 40,000 litres or more will require a BASIX Certificate and this also applies to outdoor spas.

At the Basix Certificate Centre, we can provide you with a BASIX Certificate for your swimming pool or spa from as little as $48 (including GST).

The swimming pool /spa capacity, or amount of water, in kilolitres, is that which the pool can hold when filled to the level specified by the manufacturer.

It was found that the average domestic swimming pool size in NSW is approximately 45,000 litres (or 45 kilolitres), and due to evaporation, splash and backwash factors, will require approximately half that amount every year to keep it full or approximately the swimming pools volume of water every two years to keep it a the manufacturers recommended level.   This represents an additional 10% water consumption over and above the average NSW household level.

Swimming pools and outdoor spas also use energy for pool pumps and when installed, certain types of heating systems.  On average, a swimming pool pump will use over 1,500 kWh per year, representing an additional 17% energy consumption compared to the average NSW household.  A heated swimming pool uses even more energy, and has greater evaporation and greater use of water.

 

What does a BASIX Certificate for Swimming Pool or Spa look like?

A BASIX Certificate for a Swimming Pool or Spa will look like the following, and consist of approximately 3 pages.

Although you may already have water tanks, you will still be required to install a separate water tank for swimming pool, as per the Basix Certificate requirements. 

The rainwater tank is for top-up purposes and a tap connected to the tank must be located within 10 metres from the edge of the swimming pool or spa.

If the swimming pool is not located inside, and does not include adequate shading as defined in the Basix definitions, then an ideal way of reducing water evaporation is to include a swimming pool cover.  By including a cover in your commitments, Basix will allow a reduction in the size of the rainwater tank.

A pool cover can also have the benefit of:

  • Reducing the use of water by up to 10,000 litres per month

  • Reducing the usage of chemicals, due to evaporation

  • Keeping the pool cleaner, leaves don't get the chance to enter the water.

  • With Solar blankets, they have the benefits of above, but can also extend the summer swimming period by up to 3 months, and can increase the water temperature by up to 10 degrees.

  • Some covers or blankets can act as security, ie. to keep pets etc out of the water.

Pool covers and blankets can also be installed as:

  • Pull cord systems

  • Manual rollers systems

  • Auto roller systems

Types of covers are:

It is also advisable to include a timer for the swimming pool pump, as this will economically maintain the pool with reduced energy consumption. 

When using water from a rainwater tank, the swimming pool should be disinfected to 1mg/L of free residual chlorine respectively for at least half an hour and the pH should be about 7.5. The pumps and filters should be operating during the disinfection period prior to swimming or bathing.

For an outdoor spa, the spa should be disinfected to 2mg/L of free residual chlorine respectively for at least half an hour and the pH should be about 7.5. The pumps and filters should be operating during the disinfection period prior to swimming or bathing.

What you need to do.

For us to provide you with the BASIX Certificate, we require the following information:

  • Set of drawings for the pool to be submitted to council.

  • DP number of the property

  • Lot & house number of the property

Most other information should be provided on the plan, and if further is required, we will contact you.

You can either send this information by:

Our "turn-around" time from receipt of your plans to return to you by email or post is currently 1 - 2 working days.
