Calix introduces $1 a day manhole maintenance for local councils

Sydney, Australia – Calix has announced its $1 a day manhole maintenance for local councils to address the need to maintain these assets. Many Australian councils and water utilities recognise corrosion of concrete as a major and expensive wastewater management issue, threatening a growing number of sewer assets.

According to Calix, Australia’s $40 billion of concrete sewage infrastructure, if left untreated, could corrode away in eight years from sulphide attacks as they are highly prone to corrosion.

Phil Hodgson, CEO, Calix, said, “Maintaining assets, such as manholes, is a huge undertaking for local councils. While it may be considered a priority, there is not always the budget to appropriately cover inspections, protective coating, and the administration associated with the asset maintenance. This means that, often, manholes can be left unchecked.

“To address this need, Calix is introducing a new program where we maintain these assets for councils for just $1 a day per manhole for 10 years. This removes the requirement to set aside large budgets upfront for rehabilitation and removes the risk that the manholes deteriorate because there aren’t funds available.”

Calix developed a purpose-built, vehicle-mounted rig that sprays PROTECTA-Mag, a specialised magnesium hydroxide coating product developed by Calix for long-lasting corrosion protection, in sewage manholes. With its vertical spray operation, the assets can be quickly, safely, and cost effectively protected from acid corrosion. Work is carried out without stopping the sewer flow and without the need for confined space entry.

PROTECTA-Mag has already been used to rehabilitate more than 300 corroded manholes across Australia and New Zealand.


About Calix

Calix is a multi-award-winning Australia technology company that is developing new processes and materials to solve global challenges.

The core technology is a world-first, patented kiln built in Bacchus Marsh, Victoria that produces mineral honeycomb, which are very highly active minerals.

Calix uses these minerals, which are safe and environmentally friendly, to improve waste water treatment and phosphate removal, help protect sewer assets from corrosion, and help improve food production from aquaculture and agriculture without antibiotics, fungicides, and pesticides.

Calix’s technology has also been adopted overseas, where the company is working with some of the world’s largest companies, governments and research institutions on CO2 capture.
