MEETING DATE: OCTOBER 2, 2018
SUBJECT: APPROVAL OF EQUIPMENT PROCUREMENT CONTRACT FOR THE
WASTEWATER TREATMENT PLANT ULTRAVIOLET DISINFECTION
SYSTEM AND AN APPROPRIATION ORDINANCE
RECOMMENDATION: City Council consider the procurement contract with Enviro-line Company,
Inc. for providing ultraviolet disinfection equipment at the wastewater
treatment plant and consider an ordinance appropriating the funds.
FUNDINGSOURCE: Upon approval, funds in the amount of $297,100 will be available in the
Utility Enterprise Capital Fund Account 201-48930-543-00-1801032.
BACKGROUND: The UV disinfection system is the last treatment stage of the wastewater
treatment plant (WWTP) and is vital for treating effluent water from the
plant. The existing disinfection system was installed in 1997 and is at the
end of its useful life.
The purpose of this procurement is to select a manufacturer of the
ultraviolet (UV) system based on set criteria and a scoring system that
was part of the bid package. The selection criteria was based on items
such as price, service capability, design features/layout and O&M
considerations.
Three manufacturers picked up the bid package and two responded, with
the following results from a staff selection committee:
Price Score
Enviro-line $ 297,100 82.0
Trojan $ 448,500 69.9
Once the procurement contract is awarded, the manufacturer will
commence work on the UV system and the Engineer of Record (Parkhill,
Smith and Cooper) will design the UV construction replacement project
around the selected manufacturer (Enviro-line).
The total estimated construction cost including the Enviro-line equipment
is $760,000. Staff expects to bring the construction contract to the City
Council for consideration in the spring of 2019.
Staff recommends approval.
