"At the end of the process they can see the transfer site from which biosolids are shipped to a specialised vermiculture plant for reuse in land remediation and forestry composting, and the way in which we ensure the final treated water is returned to the environment."
Hamilton's wastewater system has come a long way since 1925 when it was predominantly 14 community septic tanks.
These tanks previously discharged directly into the Waikato River and Waitawhiriwhiri Stream and were supported by a network of pipes and pump stations.
In the 1970s Hamilton's wastewater system was improved with the construction and commissioning of the Pukete Wastewater Treatment Plant.
The plant consisted of a screening plant, primary sedimentation and chlorine disinfection prior to discharge to the Waikato River.
In the past 40 years the plant has undergone several major upgrades, and now is capable of achieving high standards of treatment to meet resource management requirements, with the most recent upgrade being completed in 2014.
Because the plant is a functioning industrial site, there are some conditions on entry.
Sturdy, flat-soled and closed in shoes are required, and there is no eating, drinking or smoking during the tour.
There are narrow walkways and stairways, so the tours cannot accommodate people who are unable to meet the physical requirements, and young children, toddlers and strollers are not permitted.
For biosecurity and health and safety reasons visitors cannot take cellphones, umbrellas or bags on the tour, although raincoats are recommended in case of poor weather.
