The scope covers preventative and emergency maintenance for one diesel engine and eighty-one generators ranging from 10 kilowatts to 2,500 kilowatts across two water treatment plants, two water supply dams, two booster pump stations, one elevated water storage tank site, two water reclamation facilities, sixty-three lift stations, and two administrative/compliance buildings. Generators operate on diesel fuel, natural gas, and liquefied petroleum gas. Routine maintenance is performed monthly, semi-annually, annually, biannually, and triannually in compliance with NFPA 110 standards; emergency repair services must be provided within two hours of request on an as-needed basis.

The contract term is three years with two optional one-year extensions at the City's discretion.

Contractors must demonstrate at least five years of experience maintaining a minimum of twenty generators of varying manufacturers and sizes with minimum 480-volt 3-phase power and 30 kilowatts capacity. Contractors must maintain Commercial General Liability insurance of $1 million per occurrence and $2 million aggregate, Automobile Liability of $1 million combined single limit, and Workers' Compensation with $1 million Employer Liability limits, with the City named as additional insured.
