09.01 Water Plant Process Control System Upgrade

Home Browse Search

� � i Pequot Lakes City Council, 'i The process control system in the City's water treatment facility was installed in the late 1990's and is due for some upgrades. Overall the process continues to � work as designed, however, some of the Programmable Logic Controller hardware, programming software, and radio communication is outdated and nearing the end of its serviceable life. Over the past year or so I have been working with Spring Lake Engineering (SLE) to identify the process hardware and programming that need to be brought up to date. During that time, SLE provided us with a feasibility study that recognizes those areas needing improvement and estimated costs involved. Naturally, they were also interested in working for the City to complete these improvements. Another company, Integrated Process Solutions (IPS), was contacted by WSN to ' give us their recommendation for upgrades. After meeting with City staff and , WSN, they submitted a proposal to us in late February. In April, SLE submitted a � proposal with two options; one that follows the scope that was discussed with � WSN and fPS, and another that they and another sub-contractor of theirs (Total Control Systems) are recommending to the City as the best, most supportable, long term upgrade to the process control system. I've included proposals from both companies and also some of the highlights of the feasibility study that SLE put together. IPS, SLE, and Total Control Systems (TCS)would all come highly recommended from me and others in the industry. The City has a TCS panel at its Industrial Park lift station that has given us no probtems in 14 years of operation. We (PRASD) have worked with IPS on a smaller but similar water plant upgrade in another small community water system we operate. Their staff was very knowledgeable and easy to work with and the upgraded controls they installed have worked flawlessly since they were put in back in 2014.
