A SPLASH of colour on a few dunnies saw a bunch of young students flushed with excitement for World Toilet Day on Monday.
More than 1400 Year 4 students left their mark on the occasion by taking part in the Unitywater Think it through at the loo art competition.
Students used cardboard toilet seats to draw, write and glue important messages about valuing our sewerage system and how to look after it.
Unitywater CEO George Theo awarded first prize to Banksia Beach State School student Emma Booth when her class visited the Murrumba Downs Sewage Treatment Plant on Monday.
Emma won an iPad to take home and also one for her class, runners-up Adam Stasch, also from Banksia Beach State School and Melinda Larsen from Burpengary State School each won a family pass to Underwater World.
Banksia Beach State School principal Jacqui King said the competition was part of a unit of work where students looked at healthy waterways.
"Students gained a really good understanding of how important it is to look after our waterways," Ms King said
She said the school would use the additional iPad in the Special Education Unit.
Burpengary State School principal Brad Fox said the school submitted 45 entries.
"It was a program that captured the imagination of the students and gave them the scope to try out the knowledge they had," he said.
Mr Theo said the competition aimed to educate schoolkids about how important their sewerage system is and what they should and shouldn't flush down the loo.
"We are very fortunate here at Moreton Bay to have a world class sewerage system, when 2.6 billion people around the world don't have any sanitation at all," he said.
"The art competition was a great way of getting the message out to this young generation that everything they flush down the loo ends up in a place like the Murrumba Downs Sewage Treatment Plant.
"These plants protect the health of our community and the environment, so it's important that we don't flush things that can clog pipes or hinder the treatment process," he said.
The event was the perfect opportunity to show the students how sewage treatment plants clean up our community's effluent while protecting the health of our environment.
