Wastewater Fund CIP Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Anna Rosenberry, Administrative Services Director SUBJECT: Adopt the Wastewater Fund Capital Improvement Plan (CIP) for Fiscal Years 2018-2022. AGENDA ITEM TYPE: Consent MEETING DATE: December 12, 2016 RECOMMENDATION: Adopt the Wastewater Fund Capital Improvement Plan (CIP) for Fiscal Years 2018-2022. 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: • PW04 PROPERTY ON CORNER OF ASPEN & ROUSE – Property in close proximity has been located for purchase to potentially expand the shops and offices. This cost would be shared with Street Maintenance Fund and Water Fund. 169 • WW71 WRF FACILITY MASTER PLAN UPDATE has been added at $250,000. • WW49 ROLL-OFF STORAGE BUILDING CONSTRUCTION & POSSIBLE 2ND SCREW PRESS ENCLOSURE – This project would be a covered addition of the roll- 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 WW08-18 WASTEWATER PIPE REPLACEMENT, have been scheduled, adjusted or added based on current needs. 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 FY18.

Use SunGard.net (Naviline EDGE) as an improvement to the current system, but not a full replacement. ADVANTAGES OF APPROVAL Simplified package. Easier to integrate the various applications/programs. Easier to pull out information for end users. Easier compilation of Commission reports and packets for Community Development. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Unknown. Dependent on the option chosen. FUNDING SOURCES General Fund 33%; Water Fund 33%; Wastewater Fund 33% New Replacement Equipment Project FY20 FY21 FY22 174 CIP Project Fund Wastewater Fund PROJECT NUMBER PW03 DEPARTMENT PUBWORKS ADMIN PROJECT NAME Vehicle Maintenance Design & Storage Construction FY18 FY19 $50,000 Unscheduled DESCRIPTION OF PROJECT Design and construct vehicle storage Describe the criticality (i.e., importance) of this project to the operation: Having equipment, especially winter equipment, inside and ready to go extends the life, produces less emissions by not having to warm up and shortens response time. Which infrastructure assets are maintained by this equipment: All of our rolling stock and equipment. How is efficiency improved with this equipment: The difference in getting in a motor grader that is parked inside vs. one that is parked outside in -20 degree weather is enormous. Equipment stays in better shape. Much less wear and tear on drivetrain and hydraulics. Easily adds an hour of productivity to every shift. How is this project leveraged with other stakeholders/projects/funds: By being located next to existing city property, we could aggregate the lots giving even more useful space. ALTERNATIVES CONSIDERED Not build and only use for outdoor storage. ADVANTAGES OF APPROVAL What are the implications of deferring the purchase of this equipment: Equipment continues to degrade from the sun and exposure. Large inside storage for several departments. Equipment would be located next to current Vehicle Maintenance Shop. Good access onto Rouse and Griffin. Early morning shift equipment could be stored here so as not to disturb the neighbors in this mostly zoned Industrial area. With this building, Streets could switch to producing our own brine solution for pre wet of the sand. We wouldn't have to use mag chloride which is about 4-5 times more expensive than salt brine. Gallatin County has expressed interest in buying brine from us. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Normal building maintenance. Possibly heat with waste oil from the Shops. Possibly heat with wood chips from Forestry. FUNDING SOURCES This project totals $200,000. It will be split evenly 4 ways: Water Fund ($50,000), Wastewater Fund ($50,000), Street Maintenance ($50,000), and Parks ($50,000).

FUNDING SOURCES 100% Wastewater Fund New Replacement Equipment Project FY20 FY21 FY22 $1,000,000 183 CIP Project Fund Wastewater Fund PROJECT NUMBER WW27 DEPARTMENT ENGINEERING PROJECT NAME Annual Watershed Study & Stream Modeling FY18 $60,000 FY19 $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 and validated datasets. Describe the criticality (i.e., importance) of this project to the operation: Crucial tool to inform MPDES discharge permit negotiations and compliance with MT numeric nutrient regulations What regulations or standards are attained with this project: Future MPDES discharge permit compliance. How is this project leveraged with other stakeholders/projects/funds: Leverages cooperative relationship with Gallatin Local Water Quality District in the performance of field sampling activities. Are there other affected projects: Project 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 FY20 $60,000 FY21 $60,000 FY22 $60,000 184 CIP Project Fund Wastewater Fund PROJECT NUMBER WW39 DEPARTMENT WRF PROJECT NAME Sandblast & Paint Clarifier Drives and Beaches FY18 $90,000 FY19 $90,000 Unscheduled DESCRIPTION OF PROJECT Sandblast and paint old clarifier drives, beaches, baffles and weirs. Describe the criticality (i.e., importance) of this project to the operation: The old final clarifiers were installed in the late 1980's and need to be painted to extend their useful life. Which infrastructure assets are maintained by this equipment: Final Clarifiers. What is the impact (i.e., scope-of-use) for this equipment: Painting the clarifier drives will preserve the infrastructure and delay the purchase of new stainless drives. ALTERNATIVES CONSIDERED Do nothing ADVANTAGES OF APPROVAL What are the implications of deferring the purchase of this equipment: Not painting the clarifier drives will speed their deterioration which may result in failure of the drives before plans can be made to replace them. 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 FY20 FY21 FY22 185 CIP Project Fund Wastewater Fund PROJECT NUMBER WW42 DEPARTMENT WRF PROJECT NAME Primary Clarifier Cover FY18 FY19 Unscheduled $1,500,000 DESCRIPTION OF PROJECT Install a geodesic dome cover with 8 foot side walls on the 3 primary clarifiers. The installation would include a door, two skylights and a vent tube. The clarifier drive motor and controls would have to be explosion proof. Describe the criticality (i.e., importance) of this project to the operation: Not having to use all the primary clarifiers during the winter would allow larger particulate carbon to be flushed into the Bio-Trains postponing the purchase of supplemental carbon to reduce the total nitrogen in the facility effluent. Covering the primary clarifiers would allow the capturing of odors from the raw sewage they contain and direct these odors to treatment equipment. These odors are now reaching the residences near the facility and Springhill Road. Which infrastructure assets are maintained by this equipment: The three Primary Clarifiers. How is efficiency improved with this equipment: Not having to use all the primary clarifiers during the winter would allow larger particulate carbon to be flushed into the Bio-Trains postponing the purchase of supplemental carbon to reduce the total nitrogen in the facility effluent. What is the impact (i.e., scope-of-use) for this equipment: This equipment is used to reduce odors and improve the efficiency of the BNR process reducing nutrient discharges to the river. ALTERNATIVES CONSIDERED Do nothing ADVANTAGES OF APPROVAL What are the implications of deferring the purchase of this equipment: Odors from raw sewage are not contained within the facilities boundaries and drift to near by neighbors and traffic on Springhill Road. Enclosing the primary clarifiers will trap these odors so they can be eliminated on the property. The Bozeman WRF is limited in the amount of carbon needed to remove nitrates with the BNR process. Covering the primary clarifiers will allow more carbon to be utilized by the process improving nutrient removal year round. 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 ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED Only maintenance of odor control would be additional. FUNDING SOURCES 100% Wastewater Funds New Replacement Equipment Project FY20 FY21 FY22 186 CIP Project Fund Wastewater Fund PROJECT NUMBER WW45 DEPARTMENT WRF PROJECT NAME Final & Secondary Clarifier Launder Covers FY18 $200,000 FY19 Unscheduled DESCRIPTION OF PROJECT Cover effluent launder of one final clarifier to eliminate algal growth in the launder. Describe the criticality (i.e., importance) of this project to the operation: Secondary Launder Covers will reduce the algae in the clarifier launders to a level that they will need only to be cleaned only once or twice a year. Currently there is a brush system installed on the skimmer arm that needs to be maintained constantly to insure proper operation. Some brushes can fall into the clarifier and could damage the clarifier drive or get stuck in the waste sludge piping. Which infrastructure assets are maintained by this equipment: Final Clarifiers. How is efficiency improved with this equipment: It will eliminate the man hours needed to maintain the brush system now in place and prevent clarifier damage. What is the impact (i.e., scope-of-use) for this equipment: It will eliminate the man hours needed to maintain the brush system now in place and prevent clarifier damage. ALTERNATIVES CONSIDERED Continue using a brush system to reduce the amount of algal growth. This method requires continual maintenance and there is a risk of brushes breaking off and falling into the clarifier. This could block the wasting hopper in the clarifier. ADVANTAGES OF APPROVAL What are the implications of deferring the purchase of this equipment: The man hours used to maintain the brush system can be put to better use and possible infrastructure damage could be eliminated. Elimination of the brush system with its maintenance and dangers. Maintenance on the launder would be cut to twice a year for a quick manual cleaning allowing operators to spend time on other duties. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED None. Would actually cut operating costs (time and materials) FUNDING SOURCES 100% Wastewater Funds New Replacement Equipment Project FY20 FY21 FY22 187 CIP Project Fund Wastewater Fund PROJECT NUMBER WW49 DEPARTMENT WRF PROJECT NAME Roll-Off Storage Building Construction & Possible 2nd Screw Press Enclosure FY18 $600,000 FY19 Unscheduled DESCRIPTION OF PROJECT Construction of a roll-off building and possible 2nd screw press enclosure. Describe the criticality (i.e., importance) of this project to the operation: Currently, an enclosed area consisting of concrete blankets suspend by cables and heated with torpedo heaters keeps the roll-offs from freezing in the truck storage building, where they are stored over night during the winter. 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. How is efficiency improved with this equipment: Less energy would be used if an extension to the roll-off loading area was built that could use exhaust air from the solids dewatering building to heat it. What is the impact (i.e., scope-of-use) for this equipment: Storing roll-offs, polymer totes and possibly housing a screw press. ALTERNATIVES CONSIDERED Construction of a roll-off loading bay extension for roll-off storage and possibly a screw press enclosure. ADVANTAGES OF APPROVAL What are the implications of deferring the purchase of this equipment: Higher energy costs associated with heating a make shift storage area in the truck storage building. Increased safety risks associated with using and fueling torpedo heaters inside a building. This addition to the existing roll-off loading area would serve as storage for the sludge roll-offs to keep them from freezing and reduce odors. This addition will also be available to house a second screw press and polymer tote storage. 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 100% Wastewater Funds New Replacement Equipment Project FY20 FY21 FY22 188 CIP Project Fund Wastewater Fund PROJECT NUMBER WW50 DEPARTMENT WRF PROJECT NAME Refrigerated Automatic Sampler FY18 $10,000 FY19 Unscheduled DESCRIPTION OF PROJECT Purchase a new refrigerated sampler for the influent, primary, and effluent. Describe the criticality (i.e., importance) of this project to the operation: If the refrigerated sampler fails, samples have to be taken manually every two hours and flow proportioned. This sample is not representative of the time period from 12:30 am until 7:00 am because the plant is unmanned during that time and no samples are taken. The manual samples are taken during the highest loading on the facility and could result in an effluent limit violation. How is efficiency improved with this equipment: Manual sampling could induce errors that would make the composite sample more or less concentrated that could result in a violation. An operator's time that would be spent doing other testing or inspecting the facility is now collecting and measuring samples manually. What is the impact (i.e., scope-of-use) for this equipment: Two of the three refrigerated samplers at the facility sample the in and out going flows that are required to be tested for the facilities Discharge Monitoring Report. ALTERNATIVES CONSIDERED Keep repairing old samplers until they fail. ADVANTAGES OF APPROVAL What are the implications of deferring the purchase of this equipment: The refrigerated samplers have been repaired several times by replacing worn out parts but if the computer control components fail the repair costs will be much higher. The samplers we are using have been in service since 2000 and we have been replacing worn out parts. We need to start replacing them before the circuit boards fail. ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED None FUNDING SOURCES 100% Wastewater Funds New Replacement Equipment Project FY20 FY21 FY22 189 CIP Project Fund Wastewater Fund PROJECT NUMBER WW53 DEPARTMENT WRF PROJECT NAME Positive Displacement Lobe Pumps FY18 $50,000 FY19 Unscheduled DESCRIPTION OF PROJECT The positive displacement lobe pumps will replace the older wasting pumps that cannot provide the necessary wasting rates. Describe the criticality (i.e., importance) of this project to the operation: Being able to remove the required amount of microorganisms (WAS) from the Bio-Trains is a key factor in maintaining the facility's effluent quality. If the sludge in the wasting hoppers in final clarifiers one thru three cannot be remove at a rate fast enough to keep the sludge from going anaerobic then secondary phosphorus release will occur. Which infrastructure assets are maintained by this equipment: The wasting system from Final Clarifiers numbers one, two, and three would be serviced by these pumps. How is efficiency improved with this equipment: Positive displacement lobe pumps have a wider range of pumping speeds then the current pumps in service on this system. Maintenance costs less and they are also easier to maintain then the older pumps. What is the impact (i.e., scope-of-use) for this equipment: Pump WAS to the RST's at a rate that would maintain the proper F/M ratio and prevent secondary phosphorus. ALTERNATIVES CONSIDERED Do nothing. ADVANTAGES OF APPROVAL What are the implications of deferring the purchase of this equipment: A decrease in facility effluent quality and an increase in pump maintenance and cost. Controlling mixed liquor inventory is critical to producing high quality effluent. If solids in the mixed liquor cannot be removed fast enough, total suspended solids will increase in the effluent which will also increase the total phosphorus to the river.
