UNC-CH Koury Cistern
Inspection and Repair Plans
In the summer of 2017, Alpha & Omega Group performed a structural inspection and developed plans to repair a leaky underground 58,000 gallon rainwater harvesting cistern located at the Koury Oral Health Sciences building on the UNC-Chapel Hill campus.
The underground pre-cast tank captures stormwater runoff to supply irrigation for landscaping. Constructed around 2010, it holds about 8,100 cubic feet of water. Continuous forced ventilation was required for entry into the tank to inspect it.
From inside the tank, A&O performed a hands-on, non-destructive visual inspection of the tank walls, floor, and joints. We reviewed design and construction documents and interviewed the original designers, contractors, and manufacturers of the tank. We provided a written report that included structure photos, sketches, a repair recommendation, and engineer’s opinion of probable construction cost.
