Stormwater detention system must be watertight and able to pass leak down test during <br /> inspection. Replacement of detention system with one that meets City standards will be <br /> required if system fails to pass leak testing. <br /> The proposed stormwater detention system has a PVC liner within the system and should <br /> pass a leak test. <br /> 2. Provide Ecology approved pretreatment device upstream of detention system to prevent <br /> sediment buildup—show and call out on plans. <br /> We are proposing an Aquaswirl pretreatment system for the roof drains. The detail of the <br /> system is provided on sheet C4.4 <br /> PO Box 1478 • Everett, WA 98206 • Phone: (425)303-9363 <br /> Fax: (425)303-9362 • Email:info@insightengineering.net <br />
