General Maintenance Procedures The structural and functional integrity of the Facility shall be maintained at all times by removing and preventing drainage interference, obstructions, blockages, or other adverse effects into, through, or out of the system.. Accumulated sediment shall be removed when sediment is at or above 3 inches in depth. At minimum, StormTech's recommends annual inspections. The isolator Row should be inspected every 6 months for the first year of operation. Disposal shall be in accordance with federal, state and local regulations. To prevent debris from entering and clogging the downstream storm sewer system a wire mesh screen or similar screening device shall be installed over the outlet until final acceptance. 4. PREVENTIVE MAINTENANCE/INSPECTION • Visual inspections of all components will be conducted every 6 months. • A log shall be kept of maintenance actions, and inspections. The log should document the condition of the detention system's primary components, mowing, and silt, litter and debris removal dates. Document aeration of the basin bottoms and replanting to prevent the sealing of the basin bottom. • Written maintenance and repair records shall be maintained by the party or parties signing the attached Agreement and shall be provided to the City upon request. STORMWATER FACILITY MAINTENANCE AGREEMENT 9 Rev.11/17/2016 1� F :7}v J� I ,e 1 1 THEMOSTADVANCL NAME IN WATER MANAGEMENT SOLUTIONS"' ������ THE ISOLATOR° ROW INTRODUCTION An important component of any Stormwater Pollution Prevention Plan is inspection and maintenance.The StormTech Isolator Row is a technique to inexpensively enhance Total Suspended Solids(TSS) - removal and provide easy access for inspection and maintenance. THE ISOLATOR ROW The Isolator Row is a row of StormTech chambers,either SC-160LP, SC-310,SC-310-3,SC-740, DC-780, MC-3500 or MC-4500 models, that is surrounded with filter fabric and connected to a closely located manhole for easy access.The fabric-wrapped chambers provide for Looking down the Isolator ge Row from the settling and filtration of sediment as storm water rises in the Isolator manhole opening,woven and stone b shown between the chamber and stone base. Row and ultimately passes through the filter fabric.The open bottom chambers and perforated sidewalls(SC-310,SC-310-3 and SC-740 models)allow storm water to flow both vertically and horizontally out of the chambers.Sediments are captured in the Isolator Row protecting the storage areas of the adjacent stone and chambers from sediment accumulation. Two different fabrics are used for the Isolator Row.A woven geotextile fabric is placed between the stone and the Isolator Row chambers. ., The tough geotextile provides a media for storm water filtration and 1 provides a durable surface for maintenance operations. It is also I designed to prevent scour of the underlying stone and remain intact during high pressure jetting.A non-woven fabric is placed over theIL chambers to provide a filter media for flows passing through the r perforations in the sidewall of the chamber.The non-woven fabric is not required over the SC-160LP, DC-780, MC-3500 or MC-4500 models as these chambers do not have perforated side walls. StormTech Isolator Row with The Isolator Row is typically designed to capture the"first flush"and Overflow Spillway(not to scale) offers the versatility to be sized on a volume basis or flow rate basis. OPTIONAL An upstream manhole not only provides access to the Isolator Row but PRE-TREATMENT typically includes a high flow weir such that storm water flowrates or volumes that exceed the capacity of the Isolator Row overtop the over Ste„o CH flow weir and discharge through a manifold to the other chambers. ROW The Isolator Row may also be part of a treatment train. By treating storm water prior to entry into the chamber system,the service life can MAN W°TM be extended and pollutants such as hydrocarbons can be captured. °"�,E' Pre-treatment best management practices can be as simple as deep sump catch basins,oil-water separators or can be innovative storm water treatment devices.The design of the treatment train and selection of pretreatment devices by the design engineer is often E0 HEADER driven by regulatory requirements.Whether pretreatment is used or not, the Isolator Row is recommended by StormTech as an effective means to minimize maintenance requirements and maintenance costs. Note. See the StormTech Design Manual for detailed information on designing inlets for a StormTech system, including the Isolator Row. OPTIONAL ACCESS STORMTECH CHAMBERS THE MOST ADVANCED i �- ISOLATOR ROW I SPEC-TION!MAINTENANCE INSPECTION The frequency of inspection and maintenance varies by location.A routine inspection schedule needs to be established for each individual location based upon site specific variables.The type of land use(i.e. industrial, commercial, residential),anticipated pollutant load, percent imperviousness, climate,etc.all play a critical role in determining the actual frequency of inspection and maintenance practices. At a minimum, StormTech recommends annual inspections. Initially, the Isolator Row should be inspected every 6 months for the first year ae of operation. For subsequent years,the inspection should be adjusted based upon previous observation of sediment deposition. The Isolator Row incorporates a combination of standard manhole(s)and strategically located inspection ports (as needed).The inspection ports allow for easy access to the system from the surface,eliminating the need to perform a confined space entry for inspection purposes. If upon visual inspection it is found that sediment has accumulated,a stadia rod should be inserted to determine the depth of sediment.When the average depth of sediment exceeds 3 inches throughout the length of the Isolator Row, clean-out should be performed. MAINTENANCE The Isolator Row was designed to reduce the cost of periodic maintenance. By"isolating"sediments to just one row,costs are dramatically reduced by eliminating the need to clean out each row of the entire storage bed. If inspection indicates the potential need for maintenance,access is provided via a manhole(s) located on the end(s)of the row for cleanout. If entry into the manhole is required, please follow local and OSHA rules for a confined space entries. Maintenance is accomplished with the JetVac process.The JetVac process utilizes a high pressure water nozzle to propel itself down the Isolator Row while scouring and suspending sediments.As the nozzle is retrieved,the captured pollutants are flushed back into the manhole for vacuuming. Most sewer and pipe maintenance companies have vacuum/JetVac combination vehicles. Selection of an appropriate JetVac nozzle will improve maintenance efficiency. Fixed nozzles designed for culverts or large diameter pipe cleaning are preferable. Rear facing jets with an effective spread of at least 45"are best. Most JetVac reels have 400 feet of hose allowing maintenance of an Isolator Row up to 50 chambers long.The JetVac process shall only be performed on StormTech Isolator Rows that have AASHTO class 1 woven geotextile(as specified by StormTech)over their angular base stone. StormTech Isolator Row(not to scale) Note:Non-woven fabric is only required over the inlet pipe connection into the end cap for SC-160LP,DC-780,MC-3500 and MC-4500 chamber models and is not required over the entire Isolator Row.
