Alternate Manufacturer: ACF Environmental (R-Tank) STORMWATER DISPOSAL SYSTEM St. Marys High School

33 2.2 MATERIALS A. Base of Excavation: Shall be smooth, level and free of lumps or debris. Compact to as least 95% or as required by Engineer. Structural fill material and/or geogrid may be used to amend the structural capacity of the soil. A thin layer (3 ) of material (See Section D) is recommended to establish a level working platform. B. Geotextile: Use Typar 3801 or equivalent nonwoven geotextile with a weight of at least 8 oz. per square yard, appropriate for the soil type and depth conditions, placed on the floor of the excavation, the sides of the module, and top of the module. C. Rain tank modules: Injection moulded plastic units approximately 408mm x 685mm x 20mm (16.06 x x 0.78 ) and 408mm x 430mm x 20mm (16.06 x x 0.78 ). Plates can be pre-assembled and shipped to the site or assembled on site to make the modules. They can also be assembled into multiple stacked modules in vertical cell structures of variable height (17.2, 34.65, 51.57, 68.5, or as required), volume = 5% solid. Note that when placing cells into the excavated area, the tank should be installed as per detail for maximum strength. D. Side Backfill: Structural fill, sand or other free-draining materials compactable to 95% standard proctor, free from lumps and debris or any other sharp materials to backfill along the sides of the cellular structure. Must be compacted with powered mechanical compactor in lifts that do not exceed 12 to provide a settlement-free surface over the top and sides of the structure. E. Top Backfill: Use Side Backfill material for first 12 above the rain tank. Top backfill should be between 12 (300mm) minimum and 36 (500mm) maximum depth compacted in 6 lifts. To support H20 loads, top cover should be 18 minimum depth (24 recommended), reinforced with a geogrid 12 above the rain tank. Above the geogrid use ¾ or smaller sandy/gravel road base materials with fines less that 3%. (A top backfill cover of up to 9 is possible by using a second layer of geogrid after the next 4 of cover). If backfill mixture must be custom mixed, use a ratio of 2 parts clean ¾ drainage rock to 1 part clean sharp sand. F. Geogrid: Use Tensar BX-1200 or equivalent to reinforce backfill above RainTanks to support H20 loads (otherwise, not required). Geogrid should extend 3 feet beyond the excavation footprint. G. Utility Marker: Use metallic tape at corners of install to mark the area for future utility detection. STORMWATER DISPOSAL SYSTEM St. Marys High School

34 PART 3 - EXECUTION 3.1 INSPECTION A. Examine prepared excavation for smoothness, compaction and level. Do not start installation of rain tank system until unsatisfactory conditions are corrected. Check for presence of high water table, which must be kept at levels below the bottom of the rain tank structure at all times. B. Installation constitutes acceptance of existing conditions and responsibility for satisfactory performance. If existing conditions are found unsatisfactory, contact Project Manager for resolution. C. Prior to beginning, have a pre-construction conference on site with the manufacturer s installation professional to assure the layout and steps involved. 3.2 PREPARATION A. Using Side Backfill Material level the base of the excavated area as per engineering detail to establish a working platform for the rain tank. B. It is helpful to identify the outline of the structure on the floor of the excavation, using spray paint or chalk line, to ensure squareness during module placement. 3.3 INSTALLATION OF RAIN TANK MODULES: A. If a liner is being used in the system to harvest stormwater or prevent groundwater intrusion, install per manufacturers recommendations and per engineering detail. B. Lay geotextile on the base of the excavation and sidewalls with extra material on side to wrap the tank modules from the top. If engineering drawings do not require geotextile on the base of the excavation, place fabric a minimum of 20 (500mm) inside the outer perimeter of the rain tank footprint. C. Install rain tank modules by placing units side-by-side. Whenever possible, the large side plate of the tank should be placed on the perimeter of the system. This will typically require that the two ends of the tank area will have a row of tanks placed perpendicular to all other tanks. D. Wrap the tank modules in geotextile fabric from the sides and the top to prevent soil entry into the rain tank modules. Overlap geotextile 12 or as recommended by manufacturer. Take great care to avoid damage to (optional) liner during placement. STORMWATER DISPOSAL SYSTEM St. Marys High School

35 E. Identify locations of inlet, outlet, inspection ports, and any other penetrations of the geotextile and (optional) liner, securing pipe into boots with stainless steel pipe clamps. Support pipe in trenches during backfill operations to prevent damage to geotextile, (optional) liner or pipe. F. Start backfilling with recommended backfill, compacting in 12 maximum lifts. Place backfill CAREFULLY to avoid shoving or damaging tanks. Use a powered mechanical compactor to compact backfill on structure sides with care to avoid damage to geotextile or (optional) layer. G. With modules greater than 1.2 meters, (4 feet) deep, place piles of cover material on top of the enclosed system s outer edge to provide vertical load on perimeter modules. This will ensure compression of the top of the system and aid in resistance to side pressures from backfill operations. Backfill above system should be compacted in 6 lifts. When backfill reaches an elevation 12 above the rain tank units, place a layer of geogrid directly over the top of the backfill (required only when there will be traffic loads (H20 loads) above the tanks), extending 3 beyond the excavation walls. H. Place sufficient sandy gravel backfill (Section 2.2 E) material over geogrid to ensure support of design loads. Place cover backfill in 6 lifts and compact with vibrating plates or walk-behind rollers (do not use drivable rolling compactors) to a minimum of 95% standard proctor, with a minimum depth of 6 (12 is recommended) and a maximum depth of 36 or as specified on engineering drawings. Take care to PLACE backfill on top of structure to avoid damage to structure, geotextile or (optional) liner, using low pressure tire or track vehicles. I. Ensure that all unrelated construction traffic be kept away from the limits of excavation until the project is complete and final surface materials are in place. J. Place surfacing materials, such as groundcovers (no shrub or trees), or paving materials over the structure with care to avoid displacement of cover fill and damage to surrounding areas. 3.4 CLEANING A. Perform cleaning during the installation of work and upon completion of the work. Remove from site all excess materials, debris, and equipment. Repair any damage to adjacent materials and surfaces resulting from installation of this work. END OF SECTION STORMWATER DISPOSAL SYSTEM St. Marys High School
