|The purpose of this project is to construct a new 8-Million Gallon (MG) Ground Storage Tank (GST) at the North Water Treatment Plant (NWTP). The existing 6-MG GST at the NWTP supplies water to Pump Station 11 which pumps the water into the City's distribution system. This GST is critical in delivering water from the NWTP to the citizens of Lubbock.
During a freeze event in 2018, the air vent to the existing 6-MG GST froze shut, causing air to become trapped within the existing GST during a filling operation. This resulted in the tank becoming over pressurized, leading to structural beams separating from the roof which caused the columns within the tank to shift. The existing 6-MG GST is still in operation, but has severe structural damage and is in need of replacement.
In response to RFP 21-15819-CM, two proposals from the following contractors were received and opened on May 25, 2021.
