Making sure that wastewater does not go to waste
Have you ever wondered what happens when you flush the toilet? The water, the poo, the urine? In Adelaide, an average of 200 grams of poo and 2 litres of urine are produced per person each day.
More than half of Adelaide's daily water usage ends up down the drain. Hence managing and treating wastewater is crucial. SA Water makes sure that our wastewater does not go to waste. Recycled water is used to water parks, sporting fields and vegetable crops. Biosolids are used to improve soil fertility and crop growth.
So, how are recycled water and biosolids produced? Well, the Bolivar Wastewater Treatment Plant Community Tour is excellent in answering this. Do book yourself in for the tour if/when you have the chance. I would recommend it. The tour is free but bookings are essential. Bookings can be made via the SA Water website. You will be required to wear flat enclosed footwear, long pants and a long-sleeved shirt/top. You will also be required to arrive 15 minutes prior to your tour start time.
The wastewater treatment and reuse process involves nine steps. As a quick summary, wastewater is screened, aerated, settled, disinfected and filtered. The whole process will be explained in detail during the tour. You will also get to see the actual steps firsthand.
