Public Swimming Pool Backwash Recycling
The Average Olympic size swimming pool can use 100,000
litres of water per week in Backwash operations

There are approximately 2000 Olympic size swimming pools in Australia which would use 200,000,000 litres of water
per week in Backwash operations

Therefore in one year these 2000 Olympic size
swimming pools would use 10,400,000,000 ltrs
10.4 Gigalitres

Apart from the Environmental necessity of not wasting Water –
There are very good economical advantages
1. It is expensive to get rid of the dirty backwash water either to sewer or having it removed from site.
2. It is expensive to replace the water lost during backwash operations.

• Public Swimming Pool Backwash Recycling• Some indicative costs1. A large Public pool can use up to 120,000 litres of water per week
in backwash operations.*2. The cost of replacing this water is up to $25,000.00* per annum3. The portion of the discharge levy for sending this water to sewer
is $12,000.00 per annum4. The cost of carting the water away can also be considerable5. Additional to these costs are the disposal costs of sludge
removal. up to $8,000.00* per annum• Total cost for not recycling this water could be up to $50,000.00
per year • Or on a weekly basis approx. $1000.00

The water in the settling tank is left for a predetermined time for the contaminants to settle
The settled water is then drawn off and pumped into the main AquaZEL media filter

The next stage is to add chlorine to the water to enable a residual to be tested prior to returning the bulk of the Backwash
Water to the pool for reuse.

A Reverse Osmosis unit can be provided as an optional extra to allow a side stream of treated water to lower TDS in the final
water returned to the pool if required.
