Reverse Osmosis – Demineralised and Potable Water

Oil and Gas

Longford, Victoria


ExxonMobil’s site service upgrade to enable expansion at its Longford site required additional drinking water and demineralised water for boilers and chemical processes.  The Engineering, Procurement, Construction (EPC) contractor, CB&I, pre-selected MAK Water as a preferred supplier due to its experience supplying similar projects previously.

MAK Water became an integrated part of CB&I’s team in designing the project to meet ExxonMobil’s rigorous engineering standards and to ensure on-time delivery for this key part of the site infrastructure.


Containerised demineralised (chlorides >2 mg/l and 0 mg/l hydrogen sulphide) plant and a bore water treatment plant providing potable water compliant to Australian Drinking Water Guidelines (ADWG).
