The purpose of these specifications is to describe requirements for an annual contract for water well maintenance services. Requirements shall include, but not be limited to, routine preventive maintenance and repairs including TV inspection, flow testing, and repairs to well pumps and casings. The successful bidder must have a current Georgia state well driller’s license and any other state required certification needed to work on potable water wells. A State of Georgia Environmental Protection Division (EPD) license is required for all work performed under this contract. A copy of all required licenses must be submitted with the bid to be further considered. In general, five (5) wells per year will be covered under this contract. Wells will be designated by the Water Supply superintendent. The City reserves the right to change the wells to be covered depending on various factors including demand, indications of pumping problems, etc. All well pumps must be cleaned and disinfected prior to the reinstallation in accordance with all state regulations and American Water Works Association (AWWA) standards for well cleaning and disinfection. All wells under this contract shall be disinfected after reinstallation of equipment. This work shall be continued until two consecutive satisfactory bacteriological samples are obtained. Samples are collected, analyzed, and reported by the City’s lab at the Industrial and Domestic Water Plant. During inspection activities the contractor shall keep well appurtenances reasonably clean and shall protect all wells to reduce the possibility of contamination. The well must be disinfected prior to the pumping test by the introduction of a chlorine solution into the well under sufficient pressure to overcome the natural flow pressures of all developed water-bearing zones, and in sufficient quantity to result in a minimum chlorine residual of 50 parts per million six hours after the application of the chlorine. After disinfection, the well must be pumped until no traces of chlorine remains in the water, and two water samples, separated by 24 hours, taken for microbiological analysis. No water may be furnished for domestic use or human consumption until samples of water are collected by the City, submitted for microbiological examination, and determined to be satisfactory. If the water samples submitted are found to be unsatisfactory, the disinfection procedures must be repeated. Final payment will not be made until microbiological sampling is satisfactorily completed. All disinfection materials will be approved by a City of Savannah Representative. All disinfection activities will be performed in the presence of a City of Savannah representative. This project encouraged MBE/WBE participation.
