Drouin West Primary School originally opened in 1874 -making it the oldest school in the area of West Gippsland- is now located on the Main Neerim Road 7.5 kilometres from the main Drouin Township. The population of 182 students is drawn from the township of Drouin. Students also come from towns further away including Noojee, Neerim South, Warragul, Labertouche and Rokeby.

In 2007 Diston Wastewater installed a Sewage Treatment Plant for the school to cater for 182 students.

In 2023 the school again increased its capacity so the treatment plant and reuse system required upgrade. Due to placement of school infrastructure, traditional wastewater reuse systems would not fit. Diston were able to use their innovative Tree Cell Reuse (TCR) solution to great effect.
