To repair and augment the aging existing filtration walls at the Wylie Water Treatment Plant (WTP), the project team for this $10 million effort is ensuring that the facility remains in critical condition while the necessary renovations take place. We have developed a plan that will allow us to continue providing quality water services. .
The Wylie Water Treatment Plant’s filter influent and effluent galleries serve as the primary access and filter operations interface for plant staff. However, the common wall between the gallery and filter was in poor condition and showed signs of significant leakage and structural damage.
Work has begun on filter 4, which appears to have the most significant damage. By addressing this filter first, the team was able to assess the full scope of work required for the remaining 19 filters.
The team planned the repair process and carefully removed about one to five filters at a time during the planned shutdown period. This strategic approach allowed the team to efficiently make necessary repairs and get the filters back into service quickly, while reducing water production. An uninterrupted water supply was also ensured.
To repair each filter, workers carefully broke down to the existing concrete floor, installed new posts beneath the drainage blocks, and applied multiple layers of filter media. The installation of 8-inch thick shotcrete reinforced walls strengthens the existing walls, providing critical tensile strength and protecting against future damage.
