Masterton District Council is giving people the opportunity to get a better understanding of what happens to the town’s effluent with an open day at the Homebush Wastewater Treatment Plant on Saturday 23 March.

Free guided bus tours of the plant will give a behind-the-scenes look at the whole post-flush process and demonstrate how council is treating wastewater.

Masterton District Council Assets and Operations Manager David Hopman says the tours will provide a fascinating insight into what is a highly technical process.

“Masterton has a wastewater treatment plant that we believe the whole community should be proud of, so we are very happy to show it off,” Mr Hopman says.

Council’s vision for wastewater is that it is managed in an environmentally and fiscally sound way for the community. The open day will provide a first-hand demonstration of how it is achieving this.

The upgraded plant became fully operational in 2015.

Disposal of treated wastewater to land is a key feature. This is done through a border strip irrigation system where grass crops are planted on the strips and then harvested for baleage.

Treated wastewater will also be irrigated to neighbouring council-owned land leased for crop production.

“By seeing the system in action people will be able to appreciate that treated wastewater is a resource and safe to use in this way,” Mr Hopman says.

Homebush also discharges treated wastewater to the river, but only during times of high flow, a requirement of Council’s strict resource consent. There is a live app on the council’s website showing when it is discharging to the river.

The open day will run from 9am and 4pm. Guided tours will take about 45 minutes, with buses leaving on the hour. (Maximum group size of 20 people).
