Home My WebLink About12-9-13 Wastewater Fund.pdf Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Chris Kukulski, City Manager Anna Rosenberry, Administrative Services Director SUBJECT: Adoption of the Wastewater Fund Capital Improvement Plan (CIP) for FY15-19. AGENDA ITEM TYPE: Action MEETING DATE: December 9, 2013 RECOMMENDATION: Adopt the Wastewater Fund Capital Improvement Plan (CIP) for FY15-19. BACKGROUND: Each year, the City Manager is required to prepare a 5 Year Capital Improvements Plan and submit it to the Commission by December 15th. Staff met in October and November to develop the attached draft schedules. The Wastewater Fund CIP tracks the capital equipment replacements and construction projects for Wastewater Operations (collection system) and the Water Reclamation Facility (WRF). Items of Note: • WWIF15 - Flanders Mill – Hidden Valley Trunk Main and Lift Station is included on the Utility schedule, with no cost for the Utility shown. Total project cost on the Impact Fee CIP is $13,500,000. This is an impact fee project that will likely need underwriting support from the Utility. We are uncertain if there are project costs that would need to be paid for by the 109 Utility; ie. Non-capacity expanding project costs. These details will be firmed up once design of the main and lift station are completed. • WW29 – Energy Recovery (Methane Co-Generation) Project, has been moved back on the schedule. It is believed that the project will yield operational savings after a relatively short pay-back period, but we don’t have any engineering estimates substantiating that at this point. In the schedule, we won’t have enough cash to pay for construction without borrowing. At the point we are ready to move forward, a more detailed financing proposal, including estimated energy savings, will be brought forward. These levels of capital expenditure are in line with our adopted rate models. However, our current rate models do not include paying costs or underwriting coverage for the WWIF15 - Flanders Mill – Hidden Valley Trunk Main and Lift Station project. We will need to track on these items as we move forward with rates in the coming years. UNRESOLVED ISSUES: Estimated costs for WW44 – Modify Flotation Thickeners are not available at this point. We anticipate having those ready for Budget Preparation in January. ALTERNATIVES: As suggested by the City Commission. If the Commission is does not wish to adopt this schedule tonight, it can be scheduled for approval on a later agenda. FISCAL EFFECTS: This step in the process has no fiscal effect. Once adopted, the Capital Improvements Plan becomes the basis of the City Manager’s Recommended Budget for FY15.

This flusher vac truck is used daily to excavate around critical infrastructure i.e. fiber optics, gas, and electric lines in addition to flushing and vacuuming sewer mains. At time of replacement, this truck will be approximately 10 years old. The existing truck will be sold at auction. ALTERNATIVES CONSIDERED Continue to use older vehicle which will be costly to maintain. ADVANTAGES OF APPROVAL Increased reliability and safety for staff and wastewater operations. This piece of equipment eliminates costly repairs because we can avoid hitting utilities with a hoe and utilize the vacuum instead. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Annual Operating and Maintenance Costs: Operating and repair costs are expected to be lower than the existing vehicle. FUNDING SOURCES 100% Wastewater utility fund New Replacement Equipment Project FY17 FY18 FY19 121 CIP Project Fund Wastewater Fund PROJECT NUMBER WW27 DEPARTMENT WRF PLANT PROJECT NAME Watershed Study and Stream Modeling FY15 $60,000 FY16 $60,000 Unscheduled DESCRIPTION OF PROJECT Develop a comprehensive, multi-year watershed study and computer model for the East Gallatin River which would enable the City and DEQ to better determine stream load allocations and develop a more scientifically valid TMDL for the river segment we discharge to. This will require annual field sample collection, laboratory analytical work and detailed computer modeling using calibrated data. This multi-year study would consist of $45,000 in consulting and computer modeling fees for at least two fiscal years (FY14 and FY15) and stream sampling/lab fees of $15,000 each year. Craig recommends we should be prepared to continue this work beyond FY15 as necessary. ALTERNATIVES CONSIDERED Not undertake this work and risk having to accept the TMDL and waste load allocations the DEQ has proposed in their original draft documents. This decision could greatly limit our ability to appeal future nutrient limitations and could result in non- compliance. ADVANTAGES OF APPROVAL This watershed study will greatly enhance the City’s understand of our impact on the East Gallatin River and enable us to more successfully negotiate future permit limitations with the DEQ. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED None, unless additional stream sampling is desired in subsequent years. FUNDING SOURCES 100% Wastewater Fund New Replacement Equipment Project FY17 $60,000 FY18 $60,000 FY19 $60,000 122 CIP Project Fund Wastewater Fund PROJECT NUMBER WW28 DEPARTMENT WRF PLANT PROJECT NAME DESIGN PHASE II - WRF PLANT IMPROVEMENTS FY15 FY16 Unscheduled $5,230,000 DESCRIPTION OF PROJECT In January 2006 Morrison & Maierle Consulting Engineers completed a comprehensive Wastewater Facilities Plan. The plan recommends the City proceed with a 3-phased project schedule that includes the construction of the new Water Reclamation Facility (WRF), capable of handling our increased flows while also reducing the amount of Total Nitrogen discharged to the East Gallatin River. Phase two is expected to include one new primary clarifier, more BNR reactor basins, clarifiers, tertiary membrane filtration, liquid sludge storage tanks, anaerobic digestion, and an effluent re-use pumping station. The capacity expanding (impact fee eligible) elements are: bioreactor basins, clarifiers, and pumping station. It is possible that this phase of the project could be further divided into phase 2A and phase 2B, if necessary. ALTERNATIVES CONSIDERED A variety of treatment technologies and alternatives are presented in the January 2006 Wastewater Facilities Plan. ADVANTAGES OF APPROVAL Major capital expansion of the Bozeman WRF will enable the City to meet its estimated demand for wastewater services and still produce a high quality effluent that is in full compliance with the City’s MPDES discharge permit. 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. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Annual Operating & Maintenance Costs: no estimates at this time. FUNDING SOURCES Total Design Cost: $5,230,000. We estimate the majority of the project costs are related to regulation and maintenance issues and would be borne by the Utility Fund. Half are related to capacity expansion, and would be borne by Impact Fees. 50% Wastewater Fund, 50% Wastewater Impact Fee Fund. New Replacement Equipment Project FY17 FY18 FY19 123 CIP Project Fund Wastewater Fund PROJECT NUMBER WW29 DEPARTMENT WRF PLANT PROJECT NAME ENERGY RECOVERY (METHANE CO-GENERATION) PROJECT FY15 FY16 Unscheduled $2,200,000 DESCRIPTION OF PROJECT Consistent with the goals of the City’s Climate Action Plan & Sustainability Programs, the Bozeman WRF staff and Public Works Director recommend we move forward with our proposed investigation and installation of a methane recovery and co- generation system. This system will produce an average of 175 kW of electricity and 974,000 BTU/hour of thermal output using a generator powered entirely by WRF digester gas. This project has the potential to save the City at least $180,000 in electricity costs and substantially lower the carbon footprint of the new Bozeman WRF. This project would be implemented in 3 phases including (1) a feasibility / cost effectiveness study, (2) project engineering / design and (3) the purchase and installation of appropriate technology for the co-generation of electricity at the Bozeman WRF. Year 1: Project Feasibility Study. Year 2: Project Engineering Design - $350,000. Year 3: Equipment Purchase and Installation - $2,200,000. ALTERNATIVES CONSIDERED Continue to flare our digester methane gas. Micro-turbines and fuel-cells have been analysed and continue to be possible alternative energy recovery technologies for this project. Our research to date suggests the most proven technology currently available to help us accomplish our energy recovery goals is likely to be a GE Jenbacher internal combustion engine and heat recovery system. ADVANTAGES OF APPROVAL Current plant waste gases will be captured and utilized to reduce plant operating costs. The project has an estimated net dollar savings of $230,000 per year. It supports the City's Municipal Climate Action Plan goals. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Once construction is funded, this project results in an estimated net dollar SAVINGS of $230,000/year. FUNDING SOURCES Wastewater Fund, other grants or community partners.

INSTALLING GLASS LINED PIPE & FITTINGS WILL REDUCE THE POSSIBILITY OF NEEDING TO FLUSH THE PIPE. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED No additional costs. FUNDING SOURCES Wastewater Funds New Replacement Equipment Project FY17 FY18 FY19 134 CIP Project Fund Wastewater Fund PROJECT NUMBER WW42 DEPARTMENT WRF PLANT PROJECT NAME Primary Clarifier Covers FY15 FY16 Unscheduled $350,000 DESCRIPTION OF PROJECT INSTALLING A GEODESIC DOME COVER WITH 8 FOOT SIDE WALLS ON A PRIMARY CLARIFIER. THE INSTALLATION WOULD INCLUDE A DOOR, TWO SKYLIGHTS AND A VENT TUBE. ALSO CLARIFIER DRIVE MOTOR AND CONTROLS WOULD HAVE TO BE EXPLOSION PROOF. ALTERNATIVES CONSIDERED Do nothing ADVANTAGES OF APPROVAL COVERING THE PRIMARY CLARIFIERS WILL ALLOW ODOR CONTROL & ELIMINATE CLEANING & PAINTING. CLEANING & PAINTING OF ALL RAILINGS AND CATWALKS IS AN ON-GOING MAINTENANCE ISSUE TO REMOVE GREASE & DROPPINGS DEPOSITED BY BIRDS. COVERS ON PRIMARY CLARIFIERS WOULD ALLOW SOME CLARIFIERS NOT TO BE USED DURING THE WINTER ALLOWING MORE NEEDED CARBON TO ENTER THE BIO-TRAINS. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Only maintenance of odor control would be additional.

THE BRUSH SYSTEM REQUIRES CONTINUAL MAINTENANCE. THERE IS RISK OF BRUSHES BREAKING OFF AND FALLING INTO THE CLARIFIER THAT MAY BLOCK THE WASTING HOPPER ALTERNATIVES CONSIDERED CURRENTLY A BRUSH SYSTEM IS USED TO REDUCE THE AMOUNT OF ALGAL GROWTH WHICH REQUIRES CONTINUAL MAINTENANCE. ADVANTAGES OF APPROVAL COVERING THE CLARIFIERS WILL ELIMINATE CURRENT MAINTENANCE AND HELP REDUCE POTENTIAL HAZZARDS. MAINTENANCE WOULD BE CUT TO TWICE A YEAR ALLOWING OPERATORS TO SPEND TIME ON OTHER DUTIES AT THE PLANT.

FY15 $14,000 FY16 Unscheduled DESCRIPTION OF PROJECT Pour 20'x40' concrete pad or two tracks to support steel wheels of sludge cake hauling rolloffs in front and behind truck loading garage. ALTERNATIVES CONSIDERED Lay Steel strips anchored on asphalt to support steel wheels ADVANTAGES OF APPROVAL STEEL REINFORCED CONCRETE WOULD BE PURED WHERE THE ASPHALT HAS BEEN REMOVED, WITH A STEEL PLATE ON TOP EVEN WITH THE ASPHALT SURFACE. THIS CONFIGURATION WOULD BE STRONGER AND BE A LEVEL SURFACE THAT WILL ALLOW EASIER SNOW PLOWING ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED No additional costs FUNDING SOURCES Wastewater Funds New Replacement Equipment Project FY17 FY18 FY19 139 CIP Project Fund Wastewater Fund PROJECT NUMBER WWIF15 DEPARTMENT WWATER IF PROJECT NAME FLANDERS MILL - HIDDEN VALLEY TRUNK MAIN AND LIFT STATION FY15 FY16 Unscheduled DESCRIPTION OF PROJECT THIS PROJECT IS PRIMARILY AN IMPACT FEE ELIGIBLE PROJECT. How much of the project costs will be borne by the Utility is uncertain at this point in time. The project consists of the installation of large diameter sewer from Huffine Lane to the City Water Reclamation Facility along the Cottonwood-Flanders Mill- Hidden Valley alignment as identified in the Wastewater Facility Plan. It also includes a Regional Lift Station located at the north of the alignment and the installation of the force-main necessary to complete the project. $200,000 in design costs and $13,300,000 in construction costs. ALTERNATIVES CONSIDERED Limit development in the area served by this trunk sewer to that which can currently be served. ADVANTAGES OF APPROVAL This project will significantly increase the area which can be served by the City’s wastewater treatment infrastructure making development in this corridor possible. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Annual operating and maintenance costs. Impact fees may not be used to finance those costs. The City’s wastewater utility will pay for these costs which are estimated to be a small increment of the City’s system as a whole. FUNDING SOURCES 70% Wastewater Impact Fees (est.) = $9.3M 30% Development contribution =$4M. Some of this project could potentially be funded with Utility dollars, or a loan for the impact fee portion of the project underwritten by the Utility.
