_ KDC Systems <br />An EMCOR Company <br />Details <br />The core system is 8,000 10 points with an additional 7,000 points being monitored in <br />sub -systems. DeltaV Version 11, M Series Hardware, Delta V Historian and Win 911 were <br />utilized. Both Fieldbus and DeviceNet were used on these projects <br />Perhaps the biggest challenge in this project was the fact that the process itself was <br />somewhat experimental. Nobody had ever attempted to clean up effluent from a <br />Wastewater Facility to drinkable level on this scale before. The experimental nature of <br />the process resulted in the need to absorb multiple changes to the control narrative <br />during the course of the project. <br />To facilitate this collaborative effort, we conducted Design Workshops. The purpose of <br />these Workshops was to get input from all stakeholders and get their sign off on the <br />design. A custom software library was built and maintained. This library was managed <br />and pushed out to sub -vendors who were responsible for providing some of the sub- <br />systems. <br />The control system was built and tested off -site using a Test Platform. Rigorous testing <br />protocols were developed with the engineer and OCWD. Unwitnessed and witnessed <br />testing was conducted at our facility using the Test Platform. The thoroughly tested <br />code was then deployed on -site, greatly reducing startup time and issues. The same <br />testing was then repeated in the field on actual equipment with water to commission <br />the system. <br />Another, challenge on this project was the use of the DeltaV DCS. DeltaV is a very <br />powerful and highly integrated process controls technology which can be challenging to <br />implement. KDC Systems has mastered this technology and as a result OCWD has <br />repeatedly chosen to use us over the local Emerson business partner. <br />Page 115 <br />_ KDC Systems <br />An EMCOR Company <br />
