Sewage Treatment

A motorboat club in country Victoria was having issues with their non-MAK Water Sewage Treatment Plant (STP) that is used for grey and raw sewage treatment for sub surface irrigation. Poor initial design of the control system and reliability had rendered the plant electrically and mechanically unworkable. The result was a system that was constantly full and was producing odour that affected the club members and neighbouring properties. The motorboat club approached MAK Water to carry out an assessment and provide a plan to upgrade the controls and make process design changes as required. MAK Water was selected as the preferred contractor because of its history of working with all types of sewage treatment technologies, and the ability to act quickly to any issues with the plant.

The largest copper producer in Western Australia needed to replace their existing containerised sewage treatment plant as it was badly corroded and had deteriorated beyond economic repair. Whilst the existing plant was only 5 years old the external structure was badly corroded and the client was concerned that there would be a major failure. The material selection for the biological tank was the main issue where mild steel with only a standard paint specification was used, but as sewage is highly corrosive this had not stood the test of time. MAK Water’s 15 year design life using FRP tanks was selected to provide a complete design, manufacture and installation package for the replacement sewage treatment plant. MAK Water worked closely with the client to design a fit for purpose, long term solution that met the required treated effluent quality.

Exxon Mobil’s PNG LNG Project required a Potable Water Treatment Plant (PWTP) and a Wastewater Treatment Plant (WWTP) to service the 630 man permanent facilities compound in Port Moresby. Recognising MAK Water’s expertise in design and manufacture of high quality, fully automated, packaged water and sewage treatment plants for Oil and Gas projects, the construction contractor engaged MAK Water to design and construct the plants. Further to the offsite manufacture and supply of the plants, site installation and commissioning assistance, and a service agreement to support the facility operator were also provided.

After a series of problems with its existing sewage treatment plant a large national operator of holiday parks decided to replace the plant in Batemans Bay, NSW. The plant was required to treat deal with a very high nutrient level and treat it to meet the strict site environmental license for discharge to the environment via irrigation. Considering this was a coastal location with high corrosion issues, MAK Water delivered an innovative sewage treatment plant built from FRP to replace the steel fabricated plant that had rusted out. The plant was designed, built and tested in MAK Water’s workshop and delivered to site with detailed installation instructions and drawings, simplifying the installation for the customer’s preferred contractor. The MAK Water team traveled to site to undertake the commissioning of the plant.

A rural prison farm located south of Perth, Western Australia was undergoing a major upgrade of the existing sewage treatment plant and required additional temporary treatment capacity. The equipment needed to be onsite and operational as soon as possible. MAK Water operates an extensive hire fleet and had a suitable sewage treatment plant in stock that was able to be quickly mobilised to site. MAK Water was able to deliver the plant within three weeks and provide installation with integration of existing equipment on site.

One of the world’s leading provider of border control and immigration services was having problems with its Sewage Treatment Plant (STP). The plant was running unreliably, using a large amount of chemicals, and required a lot of operator input to comply with its environmental license conditions. MAK Water was asked to review the operation and propose a solution that reduced its ongoing costs and ensured that the treated effluent was compliant prior to discharge.
