Carlton Site Visit - May 26, 2005General CommentsCarlton has several planned projects in various stages of completion/planning:• Replacing all 6 feed water pump VFDs, putting them up on pads.• Rebuilding feed water pumps and well pumps on a rotational basis (~ every other year).• Replacing filter PLCs ~ every 2 years due to chassis in back of PLC. Facility staff arealso looking into relocating these PLCs.• Conducting infrared scans on electrical equipment. Facility staff have done thisoccasionally on some equipment and want to start a program to do it regularly. Thiswould be sub-contracted to a professional electrician.• New VFDs on high service pumps should be complete w/in 2 weeks.• New air compressor and new airlines for tools and possibly for new valves on EDRunits.• SCADA system, software, and computer system upgrade for operating the facility.Facility staff are looking into Wonderware at other locations in the water system.• All wells have been recently upgraded with mechanical seals.• A cover for the sedimentation basin is planned for next year.• The County may add up to 5 additional wells at Carlton to increase rotationalcapabilitites.Problems mentioned by facility staff include:• Some PLCs are outdated and it is hard to get parts.• The MOV couplers wear out quickly and they are looking into upgrading the valves.• They have to retrofit the MOV couplers themselves because the replacement valves arenot compatible. Ionics is preparing a quote to replace these valves.• The individual EDR unit PLCs need replacement soon.• Chemical piping is hard to get to under the sidewalk.• The process feed pump room has significant corrosion, sits at a low elevation, andwater drains toward the building. The wiring near the floor is corroding.H:\Client\SAR Co_SAR\6873C00 WATER SUPPLY MASTER PLAN UPDATE\Deliverables\TM 2 - Water System Assets\Final\Appendix B -Final.doc
