PSA reports improved wastewater readings at Exit 1, moves forward on screen RFP and SCADA installation
Summary
PSA staff reported improving wastewater readings at the Exit 1 facility, said engineers will issue an RFP for a screening system (rough estimate $150,000), and updated the board on SCADA equipment installation and a lead service line inventory due at month’s end.
At the September meeting staff for the Carroll County Public Service Authority reported that water-quality tests at the Exit 1 regional wastewater site have improved and that the authority is moving forward with engineering work to add screening and other fixes.
Staff (referred to in the meeting as Mike) said recent testing showed an E. coli reading under 1 (units not specified at the meeting), down from a previously reported figure that staff referenced as about 1,200. He said other biochemical oxygen demand (BOD) and related tests also were within acceptable ranges. To reduce maintenance issues staff said engineers are preparing an RFP for a screening system; staff estimated the screen and related work would be in the rough range of $150,000, and explained two screening options: a mechanical screen that operates from the upper side and a grinder/press alternative that would discharge to a dumpster and sit at the bottom of the structure.
Staff also updated the board on the SCADA project, saying the vendor has installed some equipment and that the system will ultimately monitor about 32 sites. The SCADA installation has faced some electrical delays but equipment cabinets are in place and monitoring will be server-hosted. The board was told that while initial stages are monitoring-only, future phases could allow remote control.
Staff reported progress on water and sewer grant work and said its lead service line inventory is due at the end of the month; the PSA’s engineer and a subcontractor are completing that work and may request an extension if necessary. The board was also told that permits from the Virginia Department of Health and VDOT were in hand for certain line-extension work (Deer Ridge) and that material availability is the remaining scheduling constraint.
Board members had questions about electrical work, screen options and the feasibility of adding new customers to the Exit 1 system; staff said until the screen and pumps are installed a significant new customer (for example, a hotel) might not be supportable.
The board did not take formal action on these infrastructure items at this meeting beyond discussing next steps and moving toward the RFP and inventory completion.
