COME RAIN, WE sHiNe:• STORMWATE�� <br /> MANAOEMENT /NC. <br /> The eslimated cost of this unit is $19,800 complete anr� delivered to the job site. This <br /> estimate assuries that the v�ult is less ihan 10 feet deep. The final syetem wst will depend <br /> on the actual depth of the units and whetfier extras like doors rather than castings are <br /> specified. The contractor is responsible for setting the StormFilter vault and all external <br /> plumbing. <br /> Typically, we recommend annual maintenance for the StormFilter treatment system, but the <br /> maintenance cycle will ullimately depend on the rain(all conditions and actual pollutant <br /> loading. If contracted with Stormwater Management Inc., the estimate maintenance cost for <br /> the system is $1,010 per cycie. <br /> Tlie precast StormFilter has an internal bypass capacity of 1.8 cfs. If the peak release rate <br /> from detentions is expected to exceed that rate,we recommend placing a high-flow bypass <br /> upstream of the StormFiiter system. Stormwater Management could provide our high-flow <br /> bypass, the StormGate, which provides a combination weir-orifice control slructure to limit <br /> the flow to the StorrnFilter, for approximately$3,800. The final cost would depend on the <br /> actual depth and size o(the unil. <br /> y �. <br /> SMIENGR: SPH 9/2/04 <br />� <br />
