Introduction ' � <br /> The StormTrapQ+7 Underground Stormwater Detention System is one of the easiest systems to inspect and` <br /> maintain because of the open design of the stormwater chambers. Afl of the areas of the system that are <br /> used to detain and store stormwater are completely accessible. StormTrapt9 does not recommend <br /> utilizing stones around the stormwater detention system for stormwater storage. <br /> Regular inspections are recommended to assure that the system is functioning as it was designed. <br /> Please call your StormTrap�Representative if you have quesGons in regards to the inspection and <br /> maintenance of the StormTrap�system. The StormTrap�Representative for your area can be found <br /> under the"ContacY'tab af the StormTrap�website(www.StormTra�.com), or 1-87T-867-6872 and <br /> press"Q"for an Administrative Assistant. ' <br /> 2. Qry Detention Systems <br /> The StormTrap�System is used to collect stormwater and detain it for a period of time. The release rate <br /> is determined by local building and environmental codes. The system is deslgned ta reduce downstream <br /> flooding after a starmwater event.This is the same concept that is used to design above ground <br /> stormwater detention ponds. Underground detention is utilized in place of detentian ponds to alfow for <br /> additionaf development such as parking lots, public parks,highways,buildings,etc. <br /> 3.Wet Detention(Water Quality)Systems • <br /> Same of the StormTrap�Systems are designed to have a permanent poo!of water in the system. This <br /> pool of water is designed to remove and collect some of the srnall solid particles from the stormwater. <br /> These pools shall be cleaned as needed, but at least annually,to ensure they meet their intended design. <br /> 4. Inspection Schedules for Municipalities <br /> �The StormTrap�l Storrnwater Detentbn System should be inspected whenever the upstream and <br /> downstream catch basins and stormwater pipes of the stormwater collection system are inspecFed or <br /> maintained, but not less than annually. This will economize the cost of the inspection if it is done at the <br /> same time the Municipal crews are visiting the area. <br /> S/Kl�"LET�P GfT TNE PRECAST ADVANTAGE.� DOUBLEf�P <br /> �can��rir.ra»� wisre.rres.arne <br /> �escriptioa: San Mateo,CA Document - Year.DocID 2011.115422 Page: 15 of 23 <br />
