StormChambersTM will arrive either on a flat bed trailer or inan enclosed van. If in an enclosed van, we will try our bestto have the driver load the pallets at the tail of the van.However, be prepared with a long chain, metal cable, orstrong rope or straps to drag a pallet from the nose of thevan. A forklift is the easiest way to unload pallets ofStormChambersTM. 2. A full pallet of StormChambersTM will weigh approximately1,700 pounds, will be about 5’ wide, 8.5’ long, and approx-imately 8.5’ high. MATERIALS NEEDED1. Wire cutters to remove the metal bands that secure theStormChambersTM to their pallets.2. Two 6’-10’ lengths of 2x4 studs to use as levers to separate the palletized StormChambersTM.3. 3” drywall screws to close in the bases of theStormChambersTM until the stone is placed around them.4. Light weight stabilization netting to go under theStormChambersTM to prevent movement of stone –shipped with the StormChambersTM.5. Heavy weight stabilization netting, to be centered beloweach inspection/clean out riser to prevent removal ofstone and soil when vacuum – cleaned with a vacuumtruck. Also to be placed under each StormChamberTM toreceive storm water from storm drain inlet pipes, to func-tion as a “splash pan” to prevent erosion of underlyingstone and soil – shipped with the StormChambersTM. 6. 1”-2” crushed, washed, hard stone for the trench base andto backfill around the StormChambersTM.7. 4 ounce non – woven filter fabric to be used at the inter-face between the stone and soil backfill and to covertrench side walls. Use Mirafi 140N, Mirafi 140NC,Synthetic Industries 401, or AMOCO 4545 or 4535 filterfabric.8. 4’ sections of 8” (unless otherwise specified), smoothwalled Schedule 40 or SDR 35 or equivalent pipe for theinterconnections between rows of StormChambersTM (checkplans for number and location of interconnections).9. Unless otherwise specified, 10” smooth walled Schedule40 or SDR 35 or equivalent pipe for inspection/clean outrisers (check plans for number and location of risers).10.Three small angle irons and 0.5” screws for each inspec-tion/clean out riser to support riser onto top portals ofStormChambersTM.11.Cleanout caps or tops for inspection/clean out risers.12.Unless otherwise specified, one casting for each inspec-tion/clean out riser in pavement (East Jordan V – 8450 orequivalent).13.Unless otherwise specified, concrete and related materialsto form 6’ x 9’ reinforced pads to hold castings for inspec-tion/clean out risers.EQUIPMENT NEEDED1. Forklift or other type of equipment to unloadStormChambersTM (see above).2. Excavator to dig the trench from the sides and to placestone and soil backfill.3. Two battery or power operated screw guns to connectbases of overlapping StormChambersTM. 4. Saws – All, router bit on a drill, or key hole saw to cutopen side and top portals in StormChambersTM.5. Light weight, tracked dozer, not exceeding 1,100 lbs/sfto grade backfill.6. Hand – operated compactor, small roller, or tracked vehiclefor fill compaction. Tracked vehicle must not exceed 1,100lbs/sf; hand operated compactor or vibratory roller must notexceed a dynamic force of 20,000 lbs.7. Transit or laser.8. Stone bucket.2 • • • w w w . h y d r o l o g i c s o l u t i o n s . c o mBEFORE YOUR STORMCHAMBERSTM ARRIVEPLEASE NOTE THAT ALL PHOTOGRAPHS AND ILLUSTRATIONS ARE FOR ILLUSTRATIVE PURPOSES ONLY. PLEASE RELY ON WHAT THE ENGINEER SPECIFIES.1. Do not excavate trench until dry weather is forecast longenough to allow at least coverage of the StormChamberTMsystem with filter fabric prior to raining to avoid soil fillingvoid spaces in the stone.2. Excavate to a width and length sufficient to accommodatethe number of StormChambersTM plus a minimum one footborder around the entire bed. The bottom of the bed mustbe level, unless otherwise specified.3. If the StormChamberTM system was designed for infiltrationand heavy clays are encountered, it is recommended thatpea gravel and sharp concrete sand be tilled into the topone foot of trench bed prior to placing the stone base. 4. Do not use heavy equipment on the excavated trench bedin order to avoid soil compaction.5. If use of heavy equipment on the excavated trench bed cannot be avoided, scarify the trench bottom and break up soilclumps before adding the stone base.Line trench walls, not trench bottom, with 4oz, non – woven filter fabric.6. Line trench walls with a 4 – ounce non – woven filter fab-ric such as Mirafi 140N or 140NC, Synthetic Industries401, or AMOCCO 4545 or 4535. Overlap adjacent filterfabric by at least 2’. Do not place filter fabric under theStormChambersTM. The filter fabric will clog, restricting theinfiltration capability of the StormChamberTM system. 7. Unless otherwise specified, place 6” of crushed, washed, 1” to2” hard stone on the bottom of the level and zero grade trench. 8. If it becomes impractical to level the stone base by hand, use alow pressure, tracked dozer, not exceeding 1,100 lbs/sf, main-taining at least 6” of stone under the tracks at all times.9. Do not use excavated trench as a sedimentation trap or basinduring construction. The fine soil particles will accumulateat the soil boundary and restrict the infiltration capability ofthe system.w w w . h y d r o l o g i c s o l u t i o n s . c o m • • • 3 WHEN YOUR STORMCHAMBERSTM ARRIVE1. Unloading – see “Before Your StormChambersTM Arrrive”,above. As a last resort, the pallets can be dragged off ofthe trailer and dropped on the ground. This will not injurethe StormChambersTM.2. Confirm the total number of StormChambersTM and contactHydroLogic Solutions immediately if the count is incorrect.3. Confirm the number of Start, Middle and EndStormChambersTM. Each pallet should be marked with the number of each.TRENCH PREPARATIONPlace lightweight stabilization netting under StormChambersTM.3. Roll out two rows of the light weight stabilization netting(provided with the StormChambersTM) perpendicular to therows of where the Start StormChambersTM will be placed.Overlap the rows by approximately 1’. Keep the netting flat;if moved, re – straighten and flatten out. Row placement begins at inflow end of chamber system with Start ModelStormChambersTM.2. Start building the StormChamberTM system with the Start ModelStormChamberTM at the inflow end of the StormChamberTMsystem. The Start Models are completely closed at the end withthe two side portals.You may need to use 2x4’s to separate chambers.1. You may need assistance in separating the StormChambersTM.Based on weather and transit conditions, sometimes theStormChambersTM become tightly compacted. SeparateStormChambersTM using two 2x4 studs along one of its sidesfor leverage. Do not use any damaged units – contactHydroLogic Solutions immediately. 4 • • • w w w . h y d r o l o g i c s o l u t i o n s . c o mSTORMCHAMBERTM INSTALLATION Place heavyweight stabilization netting underchambers receiving storm drain inflow.4. Place one piece of the heavy weight stabilization netting (pro-vided with the StormChambersTM) perpendicular to and undereach StormChamberTM that will be receiving inlet storm drainpipes. Place on top of the light weight netting and place oneedge of the netting under, and slightly extending beyond, theclosed end wall of the StormChamberTM. Have the nettingextend equally beyond both sides of the StormChamberTM.The purpose of the heavy weight stabilization netting is tofunction as a “splash pan,” preventing excavation of theunderlying stone and soil, while allowing infiltration to occur. Insert smooth wall PVC row connecting pipes.7. Mark the midpoints of 8” ID (unless otherwise specified)smooth wall pipe and insert into the adjacent StormChambersTMwhere specified so that the marked midpoint is centeredbetween the two adjacent StormChambersTM. Pipe lengthshould be sufficient to extend 6” – 12” into both adjacentStormChambersTM. Space StormChambersTM at least 9” apart at the base at the end wall.5. Place the Start Model StormChambersTM (completely closed atthe end with the two side portals), spaced a minimum of 5’ 9”apart at the center line of the end walls (9” apart at the base atthe end walls). Position the closed ends at least 1’ from thetrench wall. Cut out side portals for smooth wall PVC inflow drainpipe and row connect-ing pipes. Cut out indentation guides are provided for 8", 10" and 12" pipes.6. Cut open the side portals for the inflow storm drain pipes(size and location specified on the plans) and lateral con-necting pipes between StormChamberTM rows (8” IDSchedule 40 or SDR 35 smooth walled PVC, unless other-wise specified) with a reciprocating saw, router bit on a drill,or keyhole saw along the defined indented circle. If the cutextends more than 0.5” beyond the indented circle, place apiece of the filter fabric over the hole, cut an X just short ofthe width of the opening, and insert the pipe. The connec-tion does not need to be water tight. 12” ID smooth walledpipe is the largest diameter pipe that can be inserted intothe side portals. In order to facilitate placement, install thelateral connecting pipes in the specified StormChambersTMbefore attaching the next StormChamberTM in the row. w w w . h y d r o l o g i c s o l u t i o n s . c o m • • • 5STORMCHAMBERTM INSTALLATION (CONTINUED)Example of typical StormChamberTM layout.8. If the locations of row – connecting pipes are not specified, add 8” pipes across all rows directly opposite where the inflowstorm drain pipe(s) is inserted. This will typically connect atleast all the Start Model StormChambersTM of each row.Additional connections across all rows of StormChambersTMshould be made so that the total diameter of pipe connectionsbetween any pair of rows is approximately equal to the totaldiameter of all inflow storm drain pipes. For example, aStormChamberTM system with one 12” inflow drain pipe wouldrequire 2, 8” pipes between each row of StormChambersTM.Place first rib of next chamber over last rib of previous chamber.9. Roll out additional light weight stabilization netting, over-laying the previous sheet by 1’ and place the first rib of aMiddle Model (completely open at side portal end, partiallyopen at top portal end) over the last rib of each of the StartModel StormChambersTM. Place heavyweight stabilization netting under chambers with cleanout risers.12. Place one piece of the heavy duty stabilization netting under the top portal end of each StormChamberTM that will be installed with a10” PVC riser for access by a vacuum truck for clean out. Extendthe netting equally beyond both sides of the StormChamberTM andextend about 1’ beyond the end wall of the StormChambersTM. Thepurpose of the netting is to prevent the stone and soil from beingsucked up by the vacuum truck. 13.For large StormChamberTM systems it may be necessary to install and backfill a few StormchambersTM of all rows at a time.Screw StormChamberTM together to prevent stone inflow.10.Screw the Middle Model StormChambersTM to the StartModels near their base on both sides with regular 3” drywall screws. One screw on each side should be sufficient totemporarily hold the StormChambersTM together until thestone is placed. The gap between the two StormChambersTMnear their base must be closed enough to prevent stonefrom migrating into them to prevent the potential for fin-ished surface subsidence. End each row with and end model StormChamberTM which is closed atthe top portal end and open at the side portal end.11.Continue placing and screwing the rest of theStormChambersTM, one at a time, as necessary, inserting anyadditional lateral – connecting pipes as specified, leaving atleast 1’ between the end of the End Model (completely openat the side portal end, completely closed at the top portalend) and the trench wall. 6 • • • w w w . h y d r o l o g i c s o l u t i o n s . c o mSTORMCHAMBERTM INSTALLATION (CONTINUED)Install cleanout/inspection risers pipes.14. Cut a hole in the top portal for a 10” ID smooth walledSDR 35 or PVC Schedule 40 riser – along the larger ofthe two indented circles, unless an 8” pipe is specified.If the cut extends more than 0.5” beyond the cut out,place a piece of the filter fabric over the hole, cut an Xslightly shorter than the width of the opening, and insertthe pipe. Attach three small angle irons equally spacedapproximately 1’ up from the end of the pipe. Use 0.5”screws on riser pipe to prevent restricting insert of vacu-um truck clean out tube. It is not necessary to screw theangle irons to the StormChamberTM. The purpose of theangle irons is simply to support the pipe until the backfillis placed. Insert the bottom 1’ of pipe into the top portaland backfill. Attach top of riser pipe to a “Fernco Type”rubber cap, or to a cleanout cover assembly, as specifiedon the plans. Place an access casting in a concrete padabove, once all fill is placed, for risers in pavement. Deposit 1” – 2” crushed, washed, hard stone directly along the centerlineof the StormChambersTM.15.Deposit 1” – 2” crushed, washed, hard stone directly along thecenterline of the StormChambersTM to evenly flow down eachside to keep the StormChambersTM in proper alignment. Do notplace the stone directly against the closed end walls at thestart and end of the rows. Let the stone fall in place at theStormChamberTM end from the top of the StormChamberTM.Add stone to at least 6” above the StormChambersTM. 16.Level the stone cover with a vibratory compactor, not to exceeda dynamic force of 10,000 lbs, or with a low pressure, trackedvehicle not exceeding 1,100 lbs/sf. IMPORTANT: If low pressure, tracked dozer is used, do not rundozer on anything less than 6” of stone above the StormChambersTM.Spread stone in small piles to prevent movement of theStormChambersTM. Caution must be exercised when placing stone on top of the StormChambersTM so that excessive pressure is notapplied directly on the StormChambersTM by equipment “buckets”. 17.Cover the stone with 4 ounce non – woven filter fabric. Overlap adjacent sheets by at least 2’. w w w . h y d r o l o g i c s o l u t i o n s . c o m • • • 7 BACKFILLING1. Backfill soil must be free from large stones and largeorganic material (e.g. tree limbs and root stumps), andmust be capable of being compacted to at least 90% ofthe Standard Proctor Test (AASHTO Method T – 99). Ifnot, crusher run or other suitable backfill material mustbe used. The same type of stone surrounding theStormChambersTM can also be extended up to the pavement sub grade, if desired. 2. Backfill and compaction of the soil backfill must beachieved in lifts 6” – 8” high. Grading of lifts shouldstart in one corner of the system with a low pressure,tracked dozer, with a pressure not exceeding 1,100 lbs/sf,keeping at least 1’ of fill in front of the blade at all times.Compact lifts to 90% Standard Proctor with tracked vehi-cles not exceeding 1,100 lbs/sf, or with a hand operatedcompactor or vibratory roller not exceeding a dynamicforce of 20,000 lbs. 3. Restrict wheeled vehicles to a maximum axle load of8,000 pounds with 6” of fill over the StormChambersTM and16,000 pounds with 12” of fill.4. Keep the StormChamberTM system closed or protected fromreceiving sediment until the site is completely stabilized.IMPORTANT: After compaction of backfill and setting of final grade,avoid parking on or traversing over the StormChamberTM installationwith heavily loaded trucks and heavy equipment until paved. IMPORTANT: These instructions assume accepted construction procedures and loaded trucks that do not exceed specified DOT load limits. Uncustomary loads or improper load distributions invehicles may require additional cover. Contact HydroLogic Solutionsfor installation under abnormal conditions.
