Brendan Hanigan, acting department manager regional services, is a microbiologist with 22 years' experience in the water and sewage treatment industry.
Brendan and his team deal with everything that gets flushed or goes down a drain in your home or local businesses.
All that waste, whether it's from a toilet, shower, dishwasher or laundry makes its way through a series of sewer pipe networks until it reaches the sewage treatment plant, where the real fun and science begins.
"Sewage treatment is largely a biological process," Brendan said.
"However certain things can't be broken down quickly via that process, so we take out as many of those contaminates as we can during the first few stages of treatment," Brendan said.
The initial screening process removes large items such as, nappies, wipes, sanitary items and plastics that can't be broken down, this is then sent to landfill.
"There is also a certain level of sand, grit and food waste that gets removed at this stage through a physical treatment process, " Brendan said.
"What we then send through to our second treatment stage is material that can be broken down by microorganisms, which do the main grunt work in any sewage treatment plant."
Brendan explained that sewage treatment plants worked just like the human body, where our stomachs break down food with the help of bacteria and microorganisms.
Most of the bacteria and microorganisms are naturally occurring within the waste, and they get a little help from science and the plant operators.
"A main job of our sewage treatment plant operators is to keep our bacteria happy and healthy," Brendan said.
"Part of that is ensuring the bacteria gets regular food in the wastewater as it flows through the plant and is provided with enough oxygen."
Once this is completed TasWater is left with a cleaner disinfected water that then re-enters waterways or is reused as irrigation on agricultural land and recreational areas.
The quality of the effluent is closely monitored to ensure the environment isn't impacted.
Any waste generated from treating the water is then recycled where possible, with biosolids getting composted or applied to farmland.
There are 112 sewage treatment plants across Tasmania dealing with waste on a daily basis.
