Introduction As part of the Certification of Occupancy, the following maintenance plan has been prepared for 813 West Smuggler Street in the City of Aspen, Colorado. B. Site Description and Drainage Pattern The proposed Lot 3 also known as 813 W. Smuggler in the Ranger Station Subdivision site is approximately 6,619 square feet (0.152 acres) in size per the amended and restated plat. The north and west property lines run parallel to West Smuggler Street and North 8th Street. The south and east sides of the proposed lot is bound by Lot 4 to the south and Forest Service Headquarters land to the east. An easement on lots 1-4 create the access to lots 1-4 in a newly created alley that is currently under construction. Roadways and vegetation bind the north and south sides. The east and west sides are bound by lots 2 of Ranger Station Subdivision and Forest Service Headquarters land on the easterly side separated by a 20’ easement for a COA irrigation ditch that runs on both properties at a slight northeast diagonal. The site construction was the construction of a new home on an empty lot. The storm water on the existing site flows from southeast to the northwest. The eastern side of the site is the irrigation ditch, and stormwater flows will flow to the ditch and then northerly off site. Southern stormwater flows will be intercepted by the proposed driveway trench drains and through the Lot 3 storm system on the east side of the lot, which also contains area inlets to capture roof drainage. Flows from the west are intercepted by Lot 2 and will be contained within that lot. The east pipe system has overflow pipes directly above and is connected to the system that collects the area inlets. This storm pipe system will discharge directly into the bioretention pond. The swale on the west side of the lot captures roof drains and flows into the bioretention pond. The bioretention pond has controls that maintain water surface elevations in the pond. There is an underdrain pipe that collects stormwater that has infiltrated through the bioretention pond filter media. The under drain connects to a nyloplast basin that also has an inlet grate to capture pond overflow. The nyloplast outlet is a 6” PVC pipe that discharges into a 4’ manhole. The manhole has a pump that periodically discharges runoff to daylight. Finally, there is a pond weir that will control additional pond overflows. The weir will spread overflow to leave the site as sheet flow in a historical fashion. C. Site BMP Maintenance The following Best Management Practices (BMPs) shall be implemented to prolong the life of the storm water infrastructure and to assure that the drainage facilities are functioning properly. Refer to the As-Built plan created by High Country Engineering for locations of the drainage facilities. The list below describes BMPs that shall be implemented after construction. 1. All drainage facilities shall be inspected for damages on an annual basis. If structures are damaged to a point that they cannot function properly, then the structure must be replaced. 2. Leaves and debris shall be removed from the roof drain system in the spring, after snow melt and in the fall once the trees have lost their leaves to prevent clogging. If the roof drain system and drain pipes are functioning properly, water will not back up in the roof drains. Storm water shall drain onto the surface and enter a drainage swale or area inlets. The drain pipes shall be cleaned by using a brush system or a hose to flush out the debris. The drain pipes may need to be jetted with a high pressure water system to remove any clogged debris. 3. The proposed trench drain and area inlets shall be inspected and cleared of rubbish and debris quarterly as well as after large storm events. The drains shall be inspected after large storm events to insure proper function. If standing water is observed within the area inlet, then the grates shall be removed and the drains shall be jetted clear. 4. The detention manhole must be inspected and maintained yearly to remove sediment and debris that is washed into it. Minimum inspection and maintenance requirements include the following: a. Closely manage sediment loads on drainage facilities to prevent high sediment concentrations from clogging the drainage systems. b. Periodically remove sediment and debris that accumulates in the underground detention vault and upstream drainage facilities. c. Routinely evaluate the water surface elevation in the manhole to ensure proper pump operation. Excessive water in the manhole could mean the pump is not operating correctly or the pump discharge pipe is clogged. If drain-down times are exceeding the maximum, drain the vault via pumping and provide maintenance to pump pipe and outlet pipes. The pump manufacturer’s maintenance and operation instructions have been attached to this plan. If slow drainage persists, the system or components may need to be replaced. d. Dispose of sediment, debris/trash, and any other waste material removed from the detention vault at suitable disposal sites and in compliance with local, state, and federal waste regulations. 5. The manhole must be inspected, maintained and quarterly and following all rainfall events greater than 0.25 inches to monitor water level and accumulation of sediments in chamber. Closely manage sediment loads on drainage facilities to prevent high sediment concentrations from clogging the drainage systems. 6. The overflow control alarm shall be inspected quarterly to ensure the alarm is functioning properly. 7. The bio-retention basin will need to be inspected and maintained quarterly to make sure that the reservoirs have not become clogged and that the reservoirs are functioning properly. Debris and litter removal shall occur routinely. The perforated pipe beneath the surface of the bioretention pond will need to be inspected and maintained quarterly for clogging and standing water. Clean outs can be used to inspect pipes by cameras to determine the location of clogging or collapsed pipe. If clogging or standing water is observed, thoroughly run a sewer snake through the pipe to unclog. Should clogging or standing water remain, the growing media mix layer shall be removed and the perforated pipe shall be exposed and cleaned. After cleaning the perforated pipe, discard old growing media mix, wrap perforated pipe with filter fabric sock, and add new growing media mix. It is not recommended to jet clear the perforated pipe to prevent the filter fabric from tearing. Solid pipes may be jetted clear if clogged. 8. The grass conveyance swales will be kept up with regular mowing with a bagger to keep fine particles out of the upper layer of the system as much as possible. The swales will also need to be inspected after heavy rainstorms to remove any large debris that may have collected and they will be raked quarterly and during the fall months prior to snow fall to remove any built up tree debris that may fall during those months so they are prepared for spring thaw flows. The owners of the property will be responsible for the maintenance and upkeep of the drainage facilities. The property owner shall dispose of sediment and any other waste material removed at suitable disposal sites and in compliance with local, state, and federal waste regulations. D. Proper Function of Best Management Practices The drainage facilities will need to be inspected quarterly as well as after large storm events to assure that they are accepting all flow directed to them and to assure that they are functioning properly. Any removed material shall be disposed of in a City of Aspen approved location such as the landfill. If the roof drains, inlets and drain pipes are functioning correctly, water will not back up in the surrounding areas. Storm water shall drain to a piping system, where the runoff will be conveyed to bioretention pond. All stormwater should enter the detention pond either by infiltration into the underdrain or the overflow inlet and be conveyed to the storm manhole. The pump in the manhole should periodically discharge runoff to the surface and leave the site. If the pond is functionally properly, stormwater should drain into the pond bottom within 12 hours. If the pump is operating correctly, the water in the manhole will remain at consistent levels and the pump alarm should never alert to excessive rise in manhole water level. The infiltration area will need to be inspected annually as well as after large storm events to assure that they are accepting all flow directed to them and to assure that they are functioning properly. If the infiltration area is functioning properly, storm water will infiltrate into the filter material along the bottom of the basin. E. Record Keeping The above BMP plan shall prolong the lifespan of the storm water drainage facilities. The operation and maintenance of the storm water facilities shall be in compliance with the City of Aspen’s Urban Runoff Management Plan (URMP). If the owner cannot perform the routine facility checks discussed above, then they shall hire someone that can perform the duties in order to comply with the City of Aspen’s URMP. All inspections and any maintenance performed on the drainage facilities shall be recorded in inspection and maintenance logs and made readily available for review by the City of Aspen upon their request. 6 | EN Copyright © Liberty Pumps, Inc. 2023 All rights reserved. 7108000K Vent Vent basin in accordance with applicable plumbing codes. Piggyback Switch Operation IMPORTANT: Verify breaker is turned off before plugging in the switch. Automatic models: Plug the piggyback switch into the receptacle. The receptacle must be wired to an appropriately sized breaker. Plug the pump into the piggyback receptacle. Install the cable clamp (if supplied) for strain relief. Operation Energizing the control panel or breaker for the first time is potentially dangerous. Licensed electrical personnel should be present when the panel or breaker is energized for the first time. If faults caused by damage or poor installation practices have not been detected, serious damage, injury or death can result when power is applied. Starting System Note: These pumps come equipped with an air bleed hole to help prevent air lock. A small spray of water from this hole is normal while pump is running. 1.Verify all plumbing components are installed correctly and functional. Verify all valves are open and ready for pump use. 2.Double check all wire connections. Re-tighten all factory and field connections. 3.Ensure pump has no obstructions. 4.With all electrical and mechanical connections complete and secure, turn on power to pump. 5.Verify operation of the pump and floats. 6.Run several cycles of water through the system to verify correct control operation for the installation. Be certain to complete adequate testing, especially on systems with multiple pumps or custom control configurations. Maintenance and Troubleshooting Accidental contact with electrically live parts, items, fluid, or water can cause serious injury or death. Always disconnect pump(s) from power source(s) before handling or making any adjustments to either the pump(s), the pump system, or the control panel. Wear adequate Personal Protective Equipment when working on pumps or piping that have been exposed to wastewater. Sump and sewage pumps often handle materials that can transmit illness or disease upon contact with skin and other tissues. Maintenance As the motor is oil-filled, no lubrication or other maintenance is required. In the event the pump becomes clogged, the inlet screen can be removed to gain access to the pump impeller. Once the obstruction is removed, the anti-airlock hole should be cleaned. To keep the pump/pump system operating smoothly, perform the following routine checks: Monthly 1.Pour enough water into the sump to activate the pump when not normally in use to verify proper function. 2.Pumps that are idle in a wet basin must be removed—do not store pump in wet basin. Quarterly 1.Check pump for corrosion and wear. 2.Check for free and unobstructed float switch operation and float switch condition. The float must be able to move freely through its complete travel without any restrictions. 3.Inspect for proper check valve operation. 4.Check that the pit is free from accumulated debris, rocks or other objects that may potentially jam the pump. Annually 1.Inspect and clean basin. Replace any defective components. Troubleshooting Refer to Table 1 for troubleshooting guidance. No repair work shall be carried out during the warranty period without prior factory approval. To do so may void the warranty. Liberty Pumps, Inc. assumes no responsibility for damage or injury due to disassembly in the field. Disassembly, other than an authorized repair facility approved by Liberty Pumps or its authorized service centers, automatically voids warranty.
