HomeMy WebLinkAbout _ 4.11(c)--Approve Sole Source Purchase of Blower for Stillwater Wastewater Treatment Plant
CITY OF REDDING
REPORT TO THE CITY COUNCIL
Recommendation
Authorize the sole-source purchase of an Atlas Copco blower in the amount of $173,300 for
the City of Redding Stillwater Wastewater Treatment Plant; and approve additional funding in
an amount not to exceed $30,000 for shipping and handling, taxes, and start-up and
commissioning services.
Fiscal Impact
The Wastewater Utility Division has sufficient funds available in the approved Fiscal Year
2022-23 budget for this purchase.
Alternative Action
The City Council (Council) could choose not to approve the purchase and the allocation of
additional funds and provide alternative direction to staff.
Background/Analysis
Five Hoffman air blowers (blowers) were installed as part of the original construction of the
Stillwater Wastewater Treatment Plant (SWWTP ) in 1990. The blowers are some of the most
critical pieces of equipment for SWWTP and must be operational in order to ensure activation
of the biological process of the plant. Each of the five blowers have been rebuilt in subsequent
years and are no longer being manufactured nor are spare parts readily available. Staff
recommends replacing the failing blowers at SWWTP with the same blowers approved for
purchase for the Clear Creek Wastewater Treatment Plant (CCWWTP). This will standardize
proven equipment across the Wastewater Utility allowing for increased service efficiency of
service, reliability and reduced costs and inventory of spare parts.

Re: 4.11(c)--Approve Sole Source Purchase of Blower for Stillwater Wastewater Treatment
Plant Page 2
On July 21, 2020, the Council approved an Evaluation and Purchase agreement with Atlas
Copco to provide the City with a new blower on a “Trial and Buy” basis. This blower has
proven to be much more reliable and has a wider range of airflow that better suits the needs of
the CCWWTP. The City completed the purchase of this blower in 2021.
On February 15, 2022, the Council approved the systematic replacement of failing blowers at
the CCWWTP with new Atlas Copco blowers, as time and budget allow. Staff recommends
the same approach to systematically replace one blower per year at the SWWTP until all
existing blowers are replaced.
At this time, the Council has approved the purchase of three Atlas Copco blowers for
CCWWTP to replace failing blowers.
The Redding Municipal Code 4.20.080 – Bidding – When dispensed allows for sole source
procurements when specific criteria are met. Specifically, Section A4 states:
A. Purchase of supplies, services, or equipment shall be by bid procedures pursuant to
Sections 4.20.120 and 4.20.130, except that bidding may be dispensed with only in the
following circumstances:
4. When a sole-source procurement is based on standards previously adopted by the
City Council;
The proposed purchase method has been coordinated and approved by the City’s Purchasing
Manager and as noted, is based on standards previously adopted by Council.
Environmental Analysis
This is not a project as defined under the California Environmental Quality Act, and no further
action is required.

Product Description
ZB 5-6 VSD+
ATLAS COPCO OIL-FREE CENTRIFUGAL BLOWER
The Atlas Copco ZB 5-6 VSD+ is the latest generation of magnetic bearings centrifugal blowers It includes
advanced features ensuring efficiency to its maximum as well as enhanced reliability. Its plug-and-play
design provides simple installation and easy access for service activities.
The Atlas Copco magnetic bearing technology provides
operational peace of mind and full control over the rotating
component. No matter the conditions, the machine controls
and adjusts the shaft’s position at any given time,
guaranteeing an optimal operation. Coupled to a highly
efficiency permanent magnet motor, this machine is the ideal
combination of efficiency and reliability.
Having an efficient technology is only the first step towards the
machine’s total efficiency. The Atlas Copco ZB 5-6 VSD+ is
also delivered with a state of the art packaging, minimizing the
losses from the air entry point to the discharge flange.
The extra touch to the Atlas Copco ZB 5-6 VSD+ is given to
the cooling circuits. Proper cooling is built into the blower’s
design. Streams of fresh air are running within and around
internal components to ensure the lowest possible operating
temperature. Thanks to the internal close water loop circuit,
the motor and variable frequency drive are maintained at a
constant temperature, no matter the environmental or the
operating conditions. This design provides an extended
reliability as well as an increased lifetime of the machine.
The Atlas Copco ZB 5-6 VSD+ features even more unique
benefits. From the modulating blow-off valve extending the
machine’s turndown, to the magnetic bearing controller
continuous power feed without the need of a UPS, these are

Reliability
Atlas Copco magnetic bearing technology
The Atlas Copco magnetic bearing technology is a strong active technology. At any moment, the full control
of the shaft is ensured thanks to the magnetic force adjusting the shaft's position, no matter the conditions.
This technology:
• Ensures a full control over the rotating assembly and a
complete adjustment of the shaft’s position in order to
face any operating conditions
• Has unlimited starts and stops and no contact between
stator and rotor at any given moment
• Does not require the use of process air to operate or to
cool down components
• Combines air and water cooling to ensure extended
components’ lifetime within a compact and powerful
design
• Does not require the use of a UPS (power battery
bank) to provide power to the magnetic bearing
controller
Built-in cooling paths
The Atlas Copco ZB 5-6 VSD+ turbo blower has an advanced
cooling design. Several dedicated paths are present to provide
the optimum cooling requirement:
• The magnetic bearing cooling path is using fresh air
from outside of the blower which is cleaned and ducted
directly onto the bearings
• The internal cooling path also uses fresh cleaned air
from outside of the machine to circulate around the
mechanical components such as the permanent
magnet motor
• The Electrical cubicle cooling path is taking fresh air
from the bottom of the cubicle to the top, cooling down
every cubicle component
• The water cooling path runs through the permanent
magnet motor and high frequency drive, maintaining
these key components at their optimum operating
temperature
Regulating blow-off valve
With its new regulating algorithm, the Atlas Copco ZB 5-6
VSD+ features a regulating blow-off valve. This component
brings huge benefits to the machine:
• It allows a quick response to dynamically adjust its
position during the blower’s operation
• It provides an extended turndown in the area where
traditional turbo blowers would surge or shutdown
• It bridges flow gaps between blowers running in
parallel, allowing the process to be accurately
provided with the exact amount of flow needed

Efficiency
Atlas Copco centrifugal blower
Atlas Copco has a long history with centrifugal equipment. For more than a decade, the ZB high-speed
turbo blower range proved its superior efficiency. With this new generation, the ZB 5-6 VSD+ continues the
success story, putting efficiency in the front line of this product’s benefits. The product includes:
• Magnetic bearing technology for high efficiency
operation without the consumption of process air
• High-efficient permanent magnet motor for reduced
losses along the speed range and an optimum
operation in the complete blower’s operating map
• State-of-the-art impeller designed to operate at
dedicated pressure levels
• Premium labyrinth seal reducing leakages and
energy losses over the compression stage
Separated process air path
Too often, process air is mixed with cooling air within centrifugal turbo blowers, increasing the power
consumption of the machine. The Atlas Copco ZB 5-6 VSD+ is changing this habit and is built with a
dedicated air path going to the process, ensuring minimal pressure drops as well as minimal temperature
increase. This feature:
• Guarantees energy savings by separating cooling
air paths to the process air path and increased flow
delivered from the machine
• Ensures the lowest discharge air temperature to the
process
• Allows simple ducting for air intake from a remote
location
Plug-and-play package
When designing blowers, Atlas Copco makes a priority to build simple, easy to install and serviceable
machines. The Atlas Copco ZB 5-6 VSD+ is a perfect example of this mindset. The machine:
• Includes all necessary components straight from
the factory
• Requires a single electrical connection to feed all
the machine’s electrical components
• Has a reduced footprint and installation space
required around the machine
• Is easily transportable with forklift slots embedded
within the base frame

Working principle
Traditionally, process air is used to cool down components in centrifugal turbo blowers. This, however, has
a serious impact on the performance. There is no better way to cool down a component than having a
dedicated stream of fresh air. The Atlas Copco ZB blower separates the cooling paths from the process
path as it is presented below.
The process air path
Air is taken from the atmosphere (A), passes through a set of baffles (B) reducing its noise, it is filtered by
high-efficiency filters (C) before entering the element via a direct connection. The impeller, which is
spinning at high speed (D) provides energy to the air which then will turn into pressure. Air is then delivered
to a discharge cone and passes by a high-efficiency check valve (F) before entering the process. The
modulating blow-off valve (G) and noise cancelling silencer (H) are present to derivate air from the main
line for either protection or regulation purposes.

The magnetic bearing cooling air system
Air is taken from the atmosphere (A), passes through a set of baffles reducing its noise (B), is filtered
through a high-efficiency filter (C) before blown into the bearings via two air fans (I). After cooling down the
magnetic bearings, the warm air is being rejected to the centralized location at the top of the machine,
which can be ducted or piped outside of the blower room if needed.
The closed-loop water system
Atlas Copco ZB turbo blowers use an internal water and glycol circuit to cool down the permanent magnet
motor and high frequency drive assuring to use them at their best efficiency regardless of the operating or
ambient conditions. The closed loop is set-up as followed: a pump (J) circulates the mix through the line,
starting with the water cooled high frequency drive (K) and then followed by the water cooled permanent
magnet motor (E). Depending on the required cooling capacity, a thermostatic valve (L) adjusts the flow
going to the heat exchanger (M) or back to the pump (J).
The heat exchanger includes in the air-cooled machine variants a variable speed air fan to regulate the
required cooling power in the most precise way. If there is no need to cool down the liquid after the motor,
none of it is passing by the heatsink, totally removing the power consumption of the cooling fan. Heated air
from the heat exchanger is then driven towards the centralized cooling air grid before being rejected into
the atmosphere (ducted, piped or none of these).

CITY OF REDDING
REPORT TO THE CITY COUNCIL
Recommendation
Approve the Evaluation and Purchase Agreement with Atlas Copco Compressors LLC, in the
amount of $130,000 for an air blower at the Clear Creek Wastewater Treatment Plant, and
approve additional funding in the amount not to exceed $20,000 for shipping and handling,
taxes, installation, and start up and commissioning services.
Fiscal Impact
The Wastewater Utility Division has sufficient funds available in the approved Fiscal Year 2020-
21 budget for this purchase.
Alternative Action
The City Council has the option to not approve the agreement and the allocation of additional
funds and provide alternative direction to staff.
Background/Analysis
As part of the Clear Creek Wastewater Treatment Plant (CCWWTP) expansion project in 2012,
five (5) new Houston Service Industries (HSI) air blowers (blowers) were installed as
components of the updated wastewater treatment process. These blowers have been problematic
in their inability to reliably operate and function as designed from the time of installation. Years
of repairs, services, and replacements at the cost of the manufacturer have yet to remedy all
issues, particularly on one of the five blowers. The original five year warranty period for the
blower units formally ended in 2017. Atlas Copco Compressors LLC (Atlas Copco) has
subsequently purchased HSI and has been working with the City of Redding (City) to correct the
problems. Even though the warranty period has expired on the blowers, Atlas Copco has
continued to provide service to the City in a good faith effort to try and remedy the problems.

Report to Redding City Council July 13, 2020
Re: 4.11(b)--Evaluation & Purchase Agreement Atlas Copco Compressors LLC, for Air Blower
at CCWWTP Page 2
The proposed Evaluation and Purchase Agreement (Agreement) is a remedy from Atlas Copco to
provide the City with a new blower that is believed to better suit the needs of the CCWWTP. The
blower will be replacing a non-operational blower so there is no interruption in service or
process. The agreement will allow the City to install and operate this new blower on a trial basis
for up to 90 days. If the blower meets the operational needs, the City can purchase the blower at
cost from Atlas Copco. If the blower does not meet operational needs, the City can return the
blower and pursue other options.
The agreement has been approved as to form by the City Attorney.

CITY OF REDDING
REPORT TO THE CITY COUNCIL
Recommendation
Authorize purchase of Atlas Copco blower in the amount of $190,948.53 for the City of Redding
Clear Creek Wastewater Treatment Plant; and approve additional funding in an amount not to
exceed $30,000 for shipping and handling, taxes, and start-up and commissioning services.
Fiscal Impact
The Wastewater Utility Division has sufficient funds available in the approved Fiscal Year 2021-
22 budget for this purchase.
Alternative Action
The City Council (Council) could choose not to approve the purchase and additional funds and
provide alternative direction to staff.
Background/Analysis
As part of the Clear Creek Wastewater Treatment Plant (CCWWTP) expansion project in 2012,
five (5) new Houston Service Industries (HSI) air blowers (blowers) were installed as part of the
updated wastewater treatment process. The functionality and operation of these blowers has been
unreliable from the time they were installed. Despite the manufacturer covering the cost of years
of repairs, services, and replacements the problems have not been remedied and the blowers
continue to experience issues. Atlas Copco has subsequently purchased HSI and has been
working with the City of Redding (City) to correct the problems.

Works Director
Report to Redding City Council February 9, 2022
Re: 4.11(f)--Authorize Purchase of Blower for Clear Creek Wastewater Plant Page 2
On July 21, 2020, the Council approved an Evaluation and Purchase agreement with Atlas Copco
to provide the City with a new blower on a “Trial and Buy” basis. This blower has proven to be
much more reliable and has a wider range of airflow that better suits the needs of the CCWWTP.
The City completed the purchase of this blower in 2021. Subsequently, the other HSI blowers are
failing, and currently, there are only two of the five blowers operating as designed, including the
newest installed blower. Atlas Copco has provided a quote to purchase another blower to replace
one of the inoperable blowers. As time and budget allows, the inoperable HSI blowers will be
systematically replaced with new Atlas Copco blowers in future budget cycles. The air blowers
are some of the most critical pieces of equipment for CCWWTP and must be operational in order
to operate the biological process of the plant.

CITY OF REDDING
REPORT TO THE CITY COUNCIL
Recommendation
Authorize the purchase of Atlas Copco blower in the amount of $189,526.98 for the City of
Redding Clear Creek Wastewater Treatment Plant; and approve additional funding in an
amount not to exceed $30,000 for taxes and contingency.
Fiscal Impact
The Wastewater Utility Division has sufficient funds available in the approved Fiscal Year
2022-23 budget for this purchase.
Alternative Action
The City Council (Council) could choose not to approve the purchase or the additional funds
and, instead, provide alternative direction to staff. This would result in the need to identify a
different brand, make, or model blower which would be time consuming and could result in
no match being found increasing the potential for regulatory action.
Background/Analysis
On July 21, 2020, the Council approved the purchase of a new Atlas Copco Blower for the
Clear Creek Wastewater Treatment Plant (CCWWTP) to replace chronically failing HSI
blowers. The blower was purchased with the intent to evaluate the product and, if reliable,
move forward with this unit make and model to replace the remaining blowers.
The Atlas Copco blower was installed and has performed well. As a result, staff
recommended, and the Council approved at its meeting on February 15, 2022, both the
purchase of a second Atlas Copco blower for the CCWWTP and the systematic replacement
of remaining blowers with similar units at the CCWWTP as time and budget allow. The
second blower has been received and is currently being installed. Staff recommends
purchasing the third blower this budget year.

Report to Redding City Council January 30, 2023
Re: 4.11(a)--Purchase of Blower for Clear Creek Wastewater Treatment Plant Page 2
Per Redding Municipal Code 4.20.080 – Bidding – When dispensed with.
A. Purchase of supplies, services, or equipment shall be by bid procedures
pursuant to Sections 4.20.120 and 4.20.130, except that bidding may be
dispensed with only in the following circumstances:
4. When a sole-source procurement is based on standards previously adopted
by the City Council;
Blowers are an integral part of the biological wastewater treatment process. Without a
constant supply of air, the biological organisms cannot survive and the treatment process
would cease to function. New and reliable blowers will provide the air which is needed to
allow the CCWWTP to operate properly and continue to meet all regulatory requirements.
Environmental Review
This action is not a project as defined by the California Environmental Quality Act, and no
further action is required.
