Anglesea borefield reflections

Barwon Water youth and environment Ambassador Joel Corey shares his experiences following a visit to the Anglesea borefield.

I met Project Engineer Peter Palmieri at bore 6, where the Anglesea Borefield pre-treatment plant is located. The groundwater, located up to 400 metres below the surface is pumped into an aerator tank where it is mixed with air. There is a smell of sulfur — a result of the groundwater lying dormant in the aquifer for more than 1000 years.

The water is then piped to the first of 3 flocculation tanks. A bit like an electric mixer, the water is churned around, then stopped to allow particles to settle. The top 30 centimetres of water is skimmed off the top and piped to the next tank. The water becomes clearer as sediment and particles are removed as it moves through the tanks. The groundwater exits the third tank and is released into the settling basin.

The settling basin is set up like a long queue at the movies. The water takes about a day to snake up and down the basin until it reaches the front of the line. From here, it is pumped to Wurdee Boluc Reservoir where the water treatment process continues.

We then went and visited 2 bores; the first of which was under construction. The drilling contractors were working to drill 600 metres deep. The second bore is 1 of 5 bores currently operating.

A lot of effort has gone into ensuring the area is restored. Topsoil removed during construction has been returned, and native plants propagated from seeds from the site have been planted and are growing well.
