Wastewater CIP FY2019-2023 Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Kristin Donald, Finance Director SUBJECT: Adopt the Wastewater Fund Capital Improvement Plan (CIP) for Fiscal Years 2019-2023. AGENDA ITEM TYPE: Consent MEETING DATE: December 4, 2017 RECOMMENDATION: Adopt the Wastewater Fund Capital Improvement Plan (CIP) for Fiscal Years 2019-2023. 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. Similar to recent years past, we are bringing the various parts of the plan forward as items on the Consent agenda. We will be prepared to address questions, if they arise, at the public meeting. The Public Works, City Manager, and other city staff met in October and November to develop the attached Capital Plan for the equipment and capital needs of the Wastewater Fund. The Wastewater Fund CIP tracks the capital equipment replacements and construction projects for Wastewater Operations (collection system) and the Water Reclamation Facility (WRF). Item of Note:  WW49 ROLL-OFF STORAGE BUILDING CONSTRUCTION & POSSIBLE 2ND SCREW PRESS ENCLOSURE – This project would be a covered addition of the roll- 101 off loading area and would capture and redirect exhaust to keep the roll-offs from freezing in the winter and would act as storage for roll-offs and totes.  Several other recurring items, such as WW08-19 through WW08-23 WASTEWATER PIPE REPLACEMENT, have been scheduled, adjusted or added based on current needs for approximately $1 million a year.  WW89 HVAC heat loop optimization - Modify heating system to provide for facility needs for $250,000 scheduled for FY19. The current HVAC system is not adequately heating the digester and buildings. This poses some operational problems that range from inadequate sludge digestion to not being able to provide enough heat to buildings and keep utilities from freezing.  WW85 WRF Process Upgrades to Improve Nutrient Recovery & Capacity- This item has been added but is currently unscheduled for $12 million. This project will increase WRF capacity to meet facility plan recommendations and future discharge permit requirements. UNRESOLVED ISSUES: None. ALTERNATIVES: As suggested by the City Commission. If the Commission 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 FY19.

This will require annual field sample collection, laboratory analytic al work, and detailed computer modeling using calibrated and validated datasets. It is a crucial tool to inform MPDES discharge permit negotiations and compliance with MT numeric nutrient regulations. This project leverages cooperative relationship with Gallatin Local Water Quality District in the performance of field sampling activities, and it has significant potential to affect scope of future upgrades to WRF to meet numeric nutrient limitations imposed by DEQ Circular 12A and implemented through future MPDES discharge permits. Stream modeling may reduce or eliminate the need for future upgrades dependent upon the results of ongoing data collection and model calibrations. Modeling could identify that assimilative capacity is available in the East Gallatin River or that the EGR is nutrient limited. Model also essential to identify nutrient trade opportunities which could be a significant MPDES compliance tool. 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 limits 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 FY21 $60,000 FY22 $60,000 FY23 $60,000 115 CIP Project Fund Wastewater Fund PROJECT NUMBER WW39 DEPARTMENT WRF PROJECT NAME Resurface and Repaint Clarifiers FY19 $320,000 FY20 Unscheduled DESCRIPTION OF PROJECT Sandblast and paint clarifier drives on primary 1 and secondary 3. Beaches and weirs also need replaced on Primary 1 and 2, and on Secondary 1, 2, and 3. The old final clarifiers were installed in the late 1980's and need to be painted and resurfaced to extend their useful life. Painting and resurfacing the clarifier drives and replacing beaches and weirs will preserve the infrastructure and delay the cost of replacement. ALTERNATIVES CONSIDERED Do nothing ADVANTAGES OF APPROVAL Replace lost & chipping paint on old clarifiers to prevent further deterioration of existing infrastructure. These clarifiers have not been painted since they were installed in 1985. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED No new operating costs. FUNDING SOURCES 100% Wastewater Funds New Replacement Equipment Project FY21 FY22 FY23 116 CIP Project Fund Wastewater Fund PROJECT NUMBER WW49 DEPARTMENT WRF PROJECT NAME Roll-Off Storage Building Construction & Possible 2nd Screw Press Enclosure FY19 $1,500,000 FY20 Unscheduled DESCRIPTION OF PROJECT Engineering and construction of a roll-off building and 2nd screw press enclosure. Currently, an enclosed area consisting of concrete blankets is suspended by cables and heated with portable propane heaters which keeps the roll-offs from freezing in the truck storage building. The trucks are stored overnight during the winter so the solids inside them do not freeze. The addition would return the needed space in the truck storage building and would reduce heating costs by using the exhaust air from the solids handling building. Less energy would be used if an extension to the roll-off loading area was built. It could use exhaust air from the solids dewatering building to heat it. Also, not using the portable propane heaters would be a cost savings. Installing this screw press will allow not only redundancy but allows for the additional solids handling that the growing community will need. This project will allow for additional storage of roll-offs, polymer totes and the housing of a new screw press. ALTERNATIVES CONSIDERED Construction of an addition not to include the purchase of a new screw press. ADVANTAGES OF APPROVAL Installing this screw press will allow not only redundancy but allows for the additional solids handling that the growing community will need. This project will allow for additional storage of roll-offs, polymer totes and the housing of a new screw press. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED This addition could be heated with exhaust air from the Solids Handling Building, reducing costs. If a screw press was also housed in this addition, electrical costs for pumping and press operation would be additional. FUNDING SOURCES Digester 3 settlement money, amount TBD but estimated at $1,500,000. New Replacement Equipment Project FY21 FY22 FY23 117 CIP Project Fund Wastewater Fund PROJECT NUMBER WW54 DEPARTMENT Wastewater Operations PROJECT NAME Replace #1783 - 1995 Ford Dump Truck FY19 FY20 $95,000 Unscheduled DESCRIPTION OF PROJECT Vehicle maintenance is requesting that the vehicle be replaced due to age. It has a leaking brake booster that needs replaced, and they can’t get parts to get it repaired because the parts aren’t available for this vehicle anymore. The parts will continue to get harder to purchase in the future to keep this vehicle in service. ALTERNATIVES CONSIDERED Continue to use older vehicle which is becoming unreliable and costly to maintain. ADVANTAGES OF APPROVAL Will be a more fuel efficient and lower emissions vehicle. The new vehicle will improve safety of the crews, there would be lower repair costs and it would help maintain current operations levels. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Using an older piece of equipment that becomes more unreliable.

These funds would be used to repair or replace equipment that fails unexpectedly in an emergency situation. An unforeseen mechanical failure needs to be remedied quickly to protect the quality of facility effluent discharged into the East Gallatin. ALTERNATIVES CONSIDERED Not having this fund would defer other needed maintenance. ADVANTAGES OF APPROVAL Most processes run 24/7 and have backup systems but when the first system fails there is no backup system and repairs need to be made immediately. Not all repairs or equipment failures can be predicted and budgeted as a capital improvement project. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED None FUNDING SOURCES 100% Wastewater Funds New Replacement Equipment Project FY21 $100,000 FY22 $100,000 FY23 $100,000 120 CIP Project Fund Wastewater Fund PROJECT NUMBER WW70 DEPARTMENT WRF PROJECT NAME WRF Facility Engineering & Optimization FY19 $50,000 FY20 $50,000 Unscheduled DESCRIPTION OF PROJECT This will allow engineering to be completed on needed projects and to study plant optimization options before spending money on equipment that might not be needed or the proper type. Additionally, this will allow studies to be conducted to make sure the proposed plant optimizations will actually improve the effluent quality at a reasonable expense. ALTERNATIVES CONSIDERED Order replacement or upgrades to equipment that may not be sized correctly or made of the proper materials. Proceed with optimization projects without knowing if the project will actually improve plant performance. ADVANTAGES OF APPROVAL The advantage of having funds available to do engineering studies before any project is started will make sure that the right equipment is purchased and that it will perform properly. Optimization studies will predict actual cost/benefit over time to make sure the city is spending its money efficiently. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Currently unknown FUNDING SOURCES 100% Wastewater Funds New Replacement Equipment Project FY21 $50,000 FY22 $50,000 FY23 $50,000 121 CIP Project Fund Wastewater Fund PROJECT NUMBER WW76 DEPARTMENT WRF PROJECT NAME Third Pretreatment Screen FY19 FY20 Unscheduled DESCRIPTION OF PROJECT Purchase a third pretreatment screen and the engineering to properly install it. The two installed pretreatment screens are running 24/7 so there is no redundancy to the system. Adding a third screen will increase the capacity of pretreatment to handle increased flows from growth without bypassing the screens. This screen will prevent the clogging of pipes and pumps will preserve the effluent quality of the facility, and all equipment downstream of the screens will be better protected. Pipes and pumps that are not plugged run more efficiently and require less energy to run. ALTERNATIVES CONSIDERED Do nothing and run the risk of having to bypass the existing screens because they cannot handle the load coming into the plant. ADVANTAGES OF APPROVAL Protecting downstream infrastructure by not having to bypass the screens. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Additional cost of electricity for the motors on the screen.

ALTERNATIVES CONSIDERED Replace and repair tubes individually as they fail. ADVANTAGES OF APPROVAL The cost of replacing 4 tubes is about the same as what replacing all 20+ would cost. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED None FUNDING SOURCES None New Replacement Equipment Project FY21 FY22 FY23 130 CIP Project Fund Wastewater Fund PROJECT NUMBER WW89 DEPARTMENT WRF PROJECT NAME HVAC heat loop optimization FY19 $250,000 FY20 Unscheduled DESCRIPTION OF PROJECT Modify heating system to provide for facility needs. The current HVAC system is not adequately heating the digester and buildings. This poses some operational problems that range from inadequate sludge digestion to not being able to provide enough heat to buildings and keep utilities from freezing. ALTERNATIVES CONSIDERED Some alterations have already been made to the system to maximize the current setup. There is not an easy or cost effective alternative solution that would solve this problem. ADVANTAGES OF APPROVAL This project would improve the digester operation as well as keep buildings properly heated. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED There will be some increase the energy usage, but this has not been calculated yet.
