Barwon Water is encouraging students to put their coloured pencils and cameras to the test and enter its National Water Week competitions.
Secondary school students are invited to enter a photography and digital image competition while primary school students can enter a poster competition.
The theme for the competitions is "Healthy catchments, healthy communities".
Prizes are on offer for schools and students in both categories.
They include a training session with AFL footballer and Barwon Water youth and environment ambassador Joel Corey and world-record holding paralympian Kelly Cartwright and a $500 grant to purchase water-saving products or educational materials.
Selected photographs and posters will be displayed at the Barwon Water pavilion at the Geelong Show in October and the Colac Show in November. Posters will feature in a 2012 calendar.
Winning entries in the primary school categories will be submitted for judging in VicWater's state-wide National Water Week poster competition.
Schools that enter will also receive 50 complimentary water bottles.
Entries close on Friday 9 September, with winners announced in time for National Water Week celebrations.
National Water Week is held between 16 and 22 October and aims to improve understanding of water issues in Australia.
