SUBJECT: 4.11(d)--Approve the Sole-Source Purchase of the Rotamix Mixing Systems for
the City of Reddin
Recommendation
Approve the sole-source purchase of all City of Redding Rotamix Mixing Systems and find that
the name Rotamix in the specifications for maintenance and Public Works projects is authorized
by Public Contract Code Section 3400(c)(2) in order to match other products in use by the City.
Fiscal Impact
The typical cost of the Vaughan RotamixSystemOO (System) ranges between $80,000 to $95,000
per unit. The purchase of this System is purchased as needed.
AZteNnative Action
The City Council (Council) may choose not to make a finding to sole source a11 Vaughan
RotamixSystems�. The City of Redding (City) would then use the practice of incorporating
various brands or "or equal"products procured by low bid per PCC 3400(b). This would require
additional inventory, training and other additional costs for each brand or trade name.
Background/Analysis
The System is a mechanical hydraulic system that is used in sludge tanks, digesters, and other
similar applications with several features to keep the City wastewater operations running
efficiently. This System allows for continued mixing of the digesters without moving parts
inside the tank creating a reliable, low maintenance and cost-effective system. The Wastewater
Utility currently has this System in use within all three primary digesters at the Clear Creek
Wastewater Treatment Plant. The current upgrades needed on the secondary digester with the
Redding Organics Diversion to Energy Operations (RODEO) Project will require a mixing
system to be installed. Staff recommends matching the currently installed equipment within the
primary digesters in order to maximize spare parts, training and efficiency.

for a material, product, or service by specific brand or trade name in order to match other

Such finding would allow the benefits described above to be realized and are in the best interest
of the City.
