DESCRIPTION OF PROJECT AND NATURE OF RFP
30. Project. The City of Durham’s Department of Water Management (DWM) owns and operates a number of facilities and
sites for the purpose of water and wastewater treatment. In order to protect the health and safety of Durham residents,
these sites must maintain operation to create and supply potable drinking water, and collect and treat wastewater for the
City of Durham. To ensure that these sites maintain operational status during an event where electrical power cannot be
supplied by the power grid, these facilities have back-up generators that to supply power.

• Two Water Reclamation Facilities - Eight (8) generators
• Sixty-three Lift Stations - Sixty-three (63) generators
• DWM Mist Lake Administrative Complex - One (1) generator
• DWM Compliance Services Building and Laboratory - One (1) generator
There is one (1) diesel engine and eighty-one (81) generators in total throughout DWM facilities that range from 10-2500
kilowatts in power rating. Of the eighty-one (81) generators, three (3) are natural gas, one (1) is liquefied petroleum gas
(LPG), and the remainder are diesel. The contractor will be responsible for providing routine preventative and emergency
maintenance services to ensure safe and reliable operations of the various generators. For emergency services, tasks will be

40. Scope of Work. The City is soliciting proposals from qualified firms to perform the following services for each generator
component and its appurtenances. Each task will be signed off by the generator technician in the Exhibit C - Generator
Preventative Maintenance Checklist. Candidates are also strongly encouraged to provide their own preventative
maintenance schedule, which can substitute for DWM’s preventative maintenance checklist, so long as all the required
tasks are embedded in the contractor’s checklist.
