Wastewater Treatment for Centre for National Resilience

A long-term service client reached out to MAK Water to conduct a review on the condition of their steel reaction tanks on site. During the review it was noticed that corrosion forming on the external panels of the tanks was causing a safety hazard and replacement was necessary. MAK Water was selected to design, manufacture and install 3 x 240KL Steel rubber lined tanks on a live site where wastewater services had to remain operational. Our service team worked closely with the client to implement a strategic waste removal plan while the plant was offline during demolition and construction of the new tanks.

A major rail network operator faced escalating costs due to increasing water usage for graffiti removal from trains. As urban development and population density rise, the need for high‑capacity sustainable transport is greater than ever, yet train cleanliness remains a daily visual barometer of maintenance standards. The operator sought to recycle graffiti washbay wastewater to reduce potable water demand, meet Australian Recycled Water Guidelines and enhance overall sustainability.

After close to a decade’s successful operation, it was time for a system overhaul. To coincide with the overhaul Peachey Constructions decided to upgrade the system to incorporate the latest technology available by MAK Water. This upgrade ensured optimum treated water quality and minimised operational costs.

The QANTAS terminal at Brisbane Airport required water treatment and recycling solutions for the treatment of water from wash down of aircraft and parts. The wastewater was to be treated and reused for wash down with excess water used for local irrigation.

As part of the largest renewable energy project in Australia to provide on-demand energy and large-scale storage, extensive tunnelling was required to connect two existing dams with a new underground power station for the pumped hydro-electric scheme. The tunnelling process generates large volumes of construction wastewater that needs treatment before being discharged into sensitive alpine streams within a national park. Given the stringent environmental constraints and monitoring requirements, the client required a reliable water treatment solution to meet its sustainability goals and ensure compliance. MAK Water was selected as the solutions provider to design, manufacture, and commission two packaged water treatment plants to provide treatment of the tunnelling construction wastewater. The sludge generated from water treatment process, is dewatered onsite, to minimise transport costs prior to disposal in land-fill.

Construction and demolition waste streams from infrastructure and urban development are disposed in dedicated Construction and Demolition (C&D) landfill, separate to putrescible waste from households. Landfills produce leachate that will exceed environmental discharge limits imposed by the local environmental authorities, if not treated to remove contaminants. Through routine sampling and monitoring, a regional NSW landfill operator identified bromine levels that exceeded their discharge limits. MAK Water was approached to work in collaboration with the onsite wastewater treatment team to provide a rapid solution to limit bromine concentration to below discharge limits in the treated leachate and reduce the volume of waste that had to be trucked off-site for disposal.
