Evaluation of Clearwell No. 1, Water Treatment Plant No. 2

CTLGroup inspected Clearwell No. 1 located at Public Utilities Board (PUB) Water Treatment Plant No. 2 in Brownsville, Texas. The clearwell was built in 1967-68 of conventionally reinforced concrete. The structure measures 76 ft 6 in. by 152 ft in plan, has a wall height of approximately 12 ft, and is located below grade. The focus of the inspection was to determine the overall condition of the clearwell and the effects of reported infiltration of water into the structure through cracks visible on the roof slab underside and interior walls. High turbidity levels were also measured in the clearwell after a period of heavy rainfall.

CTLGroup evaluated the general condition of the reinforced concrete and provided repair details and associated order-of-magnitude cost estimates for repairs.
