Navasota staff report delays on pump and tank work; council approves change order for wastewater repairs
Summary
City staff reported weather delays to several water projects and identified erosion at Cedar Creek; the council approved a change order not to exceed $15,000 to repair a cracked sewer line under the wastewater plant lab slab.
City staff told the Navasota City Council that several capital projects are delayed because of weather and contractor scheduling, and the council authorized a change order to repair a sewer line discovered beneath the wastewater treatment plant lab.
Project manager Matthew Dooling said the Waterway Number 8 pump installation was postponed after heavy rain prevented contractors from getting rigging into the well site; Elevated Storage Tank Number 3 was delayed by a contractor conflict but staff expects mobilization within one to two weeks. Dooling said the city completed replacement of chlorine scales for its one‑ton tanks and that the digester blower has been set but not yet installed; a bell press overhaul is scheduled to replace wearable parts.
Staff said Cedar Creek stabilization work will focus on the area behind the wastewater plant where erosion has caused one pipe to collapse out of position. Dooling said crews will clear brush to allow engineers to inspect the area and develop a stabilization plan. He also listed six sewer manholes on North LaSalle with cracking that staff will bid to replace and raise, and said Well 5 rehabilitation is scheduled with pump removal and casing inspection.
Jennifer Raimo, public works director, described the wastewater plant change order approved by council. During lab remodeling to repair a floor drain, staff found a cracked sewer line beneath the lab slab that appeared to discharge some sewage into the ground. Raimo said the city evaluated options to access and repair the line and determined that tunneling underneath the slab was preferable to tearing out cabinetry and flooring. Raimo said the under‑slab approach was the “best option.”
Council approved the change order for the wastewater treatment plant repairs in a motion that capped the expenditure at $15,000. Raimo said work will proceed to repair the sewer piping under the slab to prevent continued leakage.
Staff also reported upcoming tree‑trimming work focused on areas east of LaSalle and a number of summer maintenance tasks. Several projects remain subject to contractor schedules and further engineering reports.
