When the Department of Conservation (DoC) was looking for an on-site wastewater system in Marahau, at the entrance to the Abel Tasman National Park, Allflow’s expertise in wastewater provided the reassurance the department needed for such a sensitive location.
Managing waste from public toilets and a café located beside an estuary and river was problematic, due to the potential for contamination. In the past, contamination tanks collected the septic waste that was then trucked out to a transfer station in Richmond. At the height of the season, up to 20,000 litres of waste each week was trucked out, at a cost of $30,000 each year.
DoC Operations Manager Mark Townshend worked closely with Allflow’s wastewater adviser Alastair Lewis on the project.
“This project has been a long time coming,” Mark says. “I was talking to Alastair about it a decade ago, when he used to run a septic waste company taking out all the waste from toilets in the Abel Tasman National Park.”
Key to the system’s overall success has been engaging Allflow to lead the project and provide ongoing system maintenance, he says.
“It’s great to have the experts here locally. They really care. They’re passionate about what they do. I can really feel that in the way they run the project, they care that it goes well.
“It’s nice working with a family business. If Alastair’s not around, then his sons will help. They are all very knowledgeable and customer focused.”
Allflow recommended a Klaro system, which provides an environmentally friendly solution by processing up to 9m3 of waste on-site each day. Read more about the Klaro wastewater treatment system.
Mark says since the Klaro system was installed in December last year, it has worked perfectly, right through the busy season.
“It’s really important to us at the Department of Conservation to have a system that we can have confidence in. It treats the waste on-site, which means we’re taking a sustainable approach and not using diesel to truck thousands of litres of waste elsewhere. While there’s a reasonable initial outlay, the running costs are minimal, and the advantages are tremendous,” he says.
