ProjectDate
Number:Scheduled:
Purpose: New Replacement Facility Equipment
Project The existing plant has reached its original design capacity of 5.8 MGD. Current
organic loadings (lbs of BOD) now exceed the plant’s original design capacity
Description:
for BOD by more than 20%. These critical loading parameters clearly point to
the need for a major facility expansion.
The City’s current MPDES (Montana Pollution Discharge Elimination System)
permit includes a compliance schedule that requires us to begin removing total
nitrogen and total phosphorous by September 2011 to meet interim Nutrient
Standards set by the State Department of Environmental Quality. In order to
meet the requirements of this schedule, the city needs to move forward with the
construction of a WRF facility, as our existing facility is not designed to remove
nitrogen & phosphorous.
Bids received for the WRF facility on October 1, 2008 put the total project costs
at a low of $65.7 Million (low bid) to a high of over $80.5 Million (high bid.)
Because the low bid was so much higher than our estimate, the project has
been scaled back but will still meet our permit requirements established for
September 2011. Total adjusted project price is now estimated at $53.8 Million.
Alternatives A variety of treatment technologies and alternatives are presented in the
January 2006 Wastewater Facilities Plan.
Considered:
Advantages
Major capital expansion of the Bozeman WRF will enable the City to meet its
ever growing demand for wastewater services and still produce a high quality
of
effluent that is in full compliance with the City’s MPDES discharge permit.
Approving
Expansion of the Bozeman WRF is consistent with the City’s long-term need to

accommodate rapid growth and economic development in the Gallatin Valley.

costs. The Facilities Plan estimates a total of $1,439,360 annually including all

remainder of eligible construction costs would be recovered via debt service on
the Utility Revenue Bonds, as money is collected in the Impact Fee Fund.

Purpose: New Replacement Facility Equipment
Project Construct ~7,900 LF of 12" and 15" sewer collector from manhole C0507 to
1E22.
Description:
Existing portions of this collector are not sized for anticipated future
development and the new portions of this collector, which will need to be
constructed with development, will need to be oversized to meet future
needs.
It is estimated that 70% of this project costs will be due to capacity
expansion and will be eligible for Wastewater Impact Fees.
The remaining 30% of the project costs will need to be provided by a
developer contribution or other source. At this time, the City’s Wastewater
Utility does not have a need to replace the existing facility; as such, no
utility dollars are scheduled to be spent.
Alternatives Limit future development in the area.

Purpose: New Replacement Facility Equipment
Project This project consists of construction of ~11,000 LF 18", 21" & 24" sewer
pipe from manhole F0330 to C0507.
Description:
The lower portion of the existing sewer is at capacity. Additional capacity
is needed to serve the future Bozeman Deaconess Hospital development
and lands to the south.
It is estimated that 70% of this project costs will be due to capacity

Project In January 2006 Morrison & Maierle Consulting Engineers completed a
comprehensive Wastewater Facilities Plan. The plan recommends the City
Description:
proceed with a 3-phased project schedule that includes the construction of a
new Water Reclamation Facility (WRF) that is capable of handling our increased
flows while also reducing the amount of Total Nitrogen discharged to the East
Gallatin River.
Phase I of the Plant improvements are scheduled for FY07-FY11.
This project is for the Engineering Pre-Design work and the Final Engineering
Design work for Phase II of the project. This phase will include one new
primary clarifier, more BNR reactor basins & clarifiers, tertiary deep bed
filtration, liquid sludge storage tanks, anaerobic digestion, dewatering cake
storage building and effluent re-use pumping station.
The vast majority of the Phase II improvements are capacity expanding, and the
project is estimated to be 100% impact fee eligible. However, once design
work begins, we will be continually evaluating the impact fee eligibility of the
features of the phase.
Alternatives A variety of treatment technologies and alternatives are presented in the
January 2006 Wastewater Facilities Plan.

Number:Scheduled:
Purpose: New Replacement Facility Equipment
Project Total adjusted project price for the Water Reclamation Facility (WRF)
construction of phase one is estimated at $53.8 Million.
Description:
Of that amount, $17.9 Million is for capacity expanding costs of construction.
The impact fee account will not have enough cash on hand to pay the costs of
construction when the facility is built. As such, impact fee revenues will be
dedicated to pay the outstanding debt in future years, as fee revenues are
collected.
At this point, approximately $4.87 Million of impact fee eligible costs will be paid
with a long-term loan (20 years, 3.75%) through the State’s Revolving Loan
Fund.
A debt schedule will be updated semi-annually with the amount of impact fee
dollars that have been dedicated to debt payments until the full amount owed is
paid.
