The overall project upgraded the entire <br />facility, including: reservoir monitoring, raw water processing, flocculation, <br />filter and backwash, chlorination, soda ash, Granulated Activated Carbon (GAC) <br />monitoring, clearwell control, distribution system, and pump station. <br />C <br />REFERENCE <br />Tony Linder <br />Water Treatment Plant Division Chief, <br />Water Services <br />County of Maui <br />Tony.Linder@c,a.maui.hi.us <br />808.270.7380 <br />CONTRACTS <br />$869,206 Piiholo WTP Upgrades <br />$534,125 lao WTP Upgrades <br />DATES <br />2015-2017 Piiholo WTP Upgrades <br />2017-2019lao WTP Upgrades <br />EQUIPMENT AND SOFTWARE <br />• Ignition SCADA <br />• Allen-Bradley ControlLogix PLCs <br />• Cisco Ethernet/Fiber <br />Trimax upgraded the PLC system comprising 10 enclosures to a new, fully - <br />redundant Allen-Bradley ControlLogix PLC system with remote 1/0. Trimax also <br />replaced the existing Wonderware SCADA system with Ignition by Inductive <br />Automation. Because the water treatment facility was required to remain <br />operational, with specific treatment process downtime limited to a maximum <br />of four hours on any given day, Trimax installed the new control system and <br />SCADA in parallel with the existing systems and limited all downtime during <br />testing to less than four hours. Once the new system testing was complete, the <br />old controls were removed, and new ones installed to final physical locations. <br />lao Surface Water Treatment Plant Upgrades <br />This $21.5 million project constructed a new surface water treatment plant in <br />central Maui with a micro -filtration treatment process. The plant has clean - <br />in -place four filter trains and backwash, and a maximum capacity of 3.2 mgd. <br />The control system operates raw water in -feed from a local stream, filtration, <br />chemical dosing, chlorine generator, chlorine contact tank, 3 MG water storage <br />tank, and pumping into the water distribution system. <br />Trimax upgraded the existing control system to fully -redundant Allen-Bradley <br />ControlLogix processors with 12 large remote 1/0 panels, including more than <br />W 6001/0 system points. Trimax also implemented a new Ignition SCADA system <br />in a fully -redundant configuration. <br />TRIMAX I A TESCO CONTROLS COMPANY Water and Waste Water Project Qualifications <br />
