Sunbury advances sewer projects: Little Walnut Creek interceptor goes to bid; Cheshire Ditch lining planned
Loading...
Summary
The Services Committee reviewed bidding and timing for a 560-foot Little Walnut Creek interceptor (Phase 2a) with anticipated bids near $660,000, discussed coordination with a county roundabout and easement needs, and heard plans for CIPP lining of Cheshire Ditch (about 4,000 feet, roughly $230,000) plus monitoring and testing.
Sunbury City staff told the Services Committee on March 4 that two major sanitary projects are moving forward: Phase 2a of the Little Walnut Creek interceptor is out to bid, and a cured-in-place pipelining (CIPP) program for Cheshire Ditch is scheduled to begin soon.
Carla, the presenting staff member, said Phase 2a will extend the existing interceptor about 560 linear feet to the north and that the city set a bid opening for Friday the 13th at 2 p.m. in the Municipal Building. "We're anticipating the cost will come in around $660,000," she said, noting the sewer reach is in the 40-foot depth range, which makes the work complex and expensive.
The interceptor timing is tied to a county-led roundabout where Cheshire Road meets Golf Course Road. Carla said the county plans to build a single-lane roundabout in 2027 and that Sunbury must execute a county agreement and negotiate easements (some temporary and some permanent) to connect Millstone Drive into the roundabout leg. Committee members said Pulte and another adjacent property owner are already aware of the project; staff will continue outreach and easement negotiations.
On Cheshire Ditch, Carla said Performance Pipeline Inc. completed cleaning and televising and will perform CIPP lining for just over 4,000 feet at a contract value of about $230,000. The work is weather-dependent; lining will proceed when conditions allow. Staff also plans post-flow monitoring with manhole readers to measure inflow and infiltration and compare the results to baseline readings. Committee members noted a separate $65,000 testing fund intended to monitor other city locations as well.
Why it matters: The interceptor and pipelining work aim to reduce inflow and infiltration into the sanitary system, preserve treatment-plant capacity and avoid more costly plant expansions.
What’s next: The Little Walnut Creek bids will be opened on the announced date; staff will report back on bid results and progress with easement negotiations and post-lining monitoring results.
