Explanation
§ The contract with The Harper Corporation will install new chemical feed systems at the Franklin, Vest, and Lee Dukes Water Treatment Plants. Chemical feed systems allow enhancements to the drinking water treatment process.
§ Charlotte Water began studying the proposed change in 2014 in conjunction with subject matter experts from a professional consulting firm. The study included bench scale analysis and a continuously operating test loop where different approaches were pilot tested.
§ The proposed treatment process is currently used by approximately 40% of the water plants in North Carolina, and is considered a Best Available Technology. North Carolina Department of Environmental Quality has approved this project.
§ Changes in the treatment process that this contract will allow are not anticipated to be implemented until fall/winter of 2017.
§ On September 9, 2015, and March 14, 2016, the proposed process change was presented to the City Council Environment Committee as part of a presentation on water quality.
§ The process change will require tanks for holding chemicals. On October 26, 2015, City Council approved the contract purchasing a total of nine tanks. The tanks have a long lead time, and were procured early to be available when the construction contractor is ready to install them.
§ On November 18, 2015, the City issued an Invitation to Bid for construction of the Phosphate Feed Systems; two bids were received from interested providers.
- In accordance to North Carolina General Statute 143-132, if three bids are not received from reputable and qualified contractors, then the project must be re-advertised. During the re-advertisement, the contract may be awarded to the lowest responsible bidder even if only one bid is received.
- The project was re-advertised on January 13, 2016; two bids were received from interested service providers.
§ The Harper Corporation was selected as the lowest responsive, responsible bidder.
§ The construction project is scheduled to be completed by November 2016.
