Over a three year period, Mipac has undertaken control systems upgrades/expansions to four water treatment plants owned and operated by Seqwater. Each of these plants received a process upgrade with new water treatment process equipment and requiring additional control systems and integration/upgrades with existing operating control systems and operator SCADA interfaces.
Each plant processed a significant portion of Brisbane’s potable water supply and as such, commissioning and cutover was undertaken with a high level of attention to process to ensure no impact to Brisbane’s water supply production
