MOUNT PLEASANT — The Mount Pleasant Municipal Utilities Board has scheduled a public hearing on a proposed transmission facility joint ownership agreement with Ameren Transmission Company of Illinois while also receiving an update on new complications involving the city’s Well 7 project.
During a special meeting Tuesday, board members unanimously approved Resolution 2605, setting a public hearing for 5 p.m. June 16 at the Municipal Utilities Board Room, 509 N. Adams Street.
Utility officials said the hearing is a required step before entering into the proposed agreement with Ameren. Manager Nathan Lucas told the board the contract has undergone months of review by utility staff, legal counsel, bond attorneys, engineering consultants and Ameren representatives.
The board’s regular meeting is scheduled for 3:30 p.m. June 16, immediately before the public hearing.
Well 7 Project Encounters New Concerns
Following approval of the hearing date, utility officials updated board members on a new challenge involving Well 7.
According to Lucas, recent discussions with contractors and engineers raised concerns about plans to reinstall the utility’s existing 12-inch pump and motor into an 18-inch casing at the well site.
The issue centers on the limited clearance between the equipment and the casing. Lucas said the current pump and motor assembly is leaving less than an inch of clearance inside the casing.
Contractors expressed concern that the tight fit could lead to rubbing against the casing, damage to wiring and piping, and premature equipment failure.
“They’re concerned we could be pulling that equipment back out in six months,” Lucas told board members.
The concern has prompted additional engineering review by McClure Engineering and other consultants. Engineers are now evaluating whether the utility may need to use a smaller pump system.
Lucas said the well should still be capable of producing its intended capacity of approximately 2,000 gallons per minute, but a smaller pump could require operating at higher pressures, potentially creating additional challenges elsewhere in the water system.
The review is also examining how the smaller well casing may affect water flow and drawdown characteristics compared to the larger casing originally anticipated during design.
Lucas said the findings could impact equipment already purchased for the project, although officials are still determining the full extent of any financial consequences.
Water Testing Continues
Meanwhile, utility staff continue to pump and test water from Well 7 while engineers work through the latest issues.
Lucas said water is being moved through the system regularly to prevent stagnation, which could create water quality concerns.
Although most recent tests have been satisfactory, utility officials reported occasional failed tests during the evaluation process and said they want to ensure the well is operating reliably before connecting it to the municipal water supply.
Additional information on both the Ameren agreement and the Well 7 project is expected to be discussed during upcoming utility board meetings.
