Manorvale Primary School won the rainfall data competition in 2002 by reducing water consumption by 25% since October 2001, through the installation of anti-vandal taps and automatic sprinkler systems. Other water-sensitive activities undertaken by the school included planting suitable plants, a monthly contract with a green plumber to check and maintain taps and installing a rainwater tank. The challenge, which began during National Water Week 2002, involved students from 100 schools.
