Installation and Fabrication HDPE AquaShield Products Fabrication and Installation Throughout this section and in our individual product specifications, references will be made to specific ASTM

That is why all of the patented products are fabricated, inspected and tested before leaving for the job site.

Because each system is constructed of High-Density Polyethylene (HDPE), even the largest units can be off-loaded and installed without the use of a crane or other special lifting equipment.

3 Installation and Fabrication HDPE AquaShield Products Fabrication and Installation Throughout this section and in our individual product specifications, references will be made to specific ASTM standards for the manufacturing and the installation of the AquaShield products. Quality control is a high priority within AquaShield. That is why all of the patented products are fabricated, inspected and tested before leaving for the job site. The AquaShield systems are a modular design and constructed to facilitate the installation process. Because each system is constructed of High-Density Polyethylene (HDPE), even the largest units can be off-loaded and installed without the use of a crane or other special lifting equipment. Lifting cables are provided on each Aqua-Swirl and Aqua-Filter, allowing an excavator or backhoe to maneuver and position the system. Furthermore, the systems can be stored on the job site following offloading to accommodate changing schedules. Stub-outs for the inlet and outlet are part of the modular design of the Aqua-Swirl and Aqua-Filter, which allows the contractor to attach the pipes to the Lifting cable for installation inlet and outlet of the Stormwater Treatment System with couplings. The Aqua-Guardian is also completely assembled at the factory and ready for installation after removing the shipping protection. Typically, an AquaShield representative is present on-site to assist in the installation process. Both the Aqua-Swirl and the Aqua-Filter come with risers and custom manhole frames and covers. Delivery is typically less than four weeks from final approval of shop drawings. 2

Installation and Fabrication System Fabrication All internal and structural components of the AquaShield line of stormwater treatment products are constructed with HDPE material, which is strong,

Furthermore, HDPE has a density that is one-eighth that of steel, so it is both A hot air welded joint lightweight and flexible.

4 Installation and Fabrication System Fabrication All internal and structural components of the AquaShield line of stormwater treatment products are constructed with HDPE material, which is strong, resilient, extremely tough and durable. HDPE is also resistant to chemicals and corrosion, and can withstand high sodium conditions. Furthermore, HDPE has a density that is one-eighth that of steel, so it is both A hot air welded joint lightweight and flexible. All connections are normally joined by heat/butt fusion, extrusion, and hot air welding techniques which produces fully restrained joints with zero leakage. Unlike other stormwater treatment systems that are constructed of concrete enclosures and field assembled components, the AquaShield line of stormwater treatment products are fully assembled at the factory allowing for easy on-site handling, installation and connection to the storm drainage structure. AquaShield handles all workmanship to ensure consistent quality of our patented systems. Our line of stormwater treatment products arrive at the job site ready for installation and use.

Installation and Fabrication Aqua-Swirl Installation Routine installation steps for the Aqua-Swirl units involve preparation and excavation of the area that is to contain the Aqua-Swirl.

Prior to shipping, the purchasing contractor provides written confirmation to install AquaShield products in accordance with manufacturer's specifications.

5 Installation and Fabrication Aqua-Swirl Installation Routine installation steps for the Aqua-Swirl units involve preparation and excavation of the area that is to contain the Aqua-Swirl. This includes grading, leveling, and compacting the base material before lowering the unit into the excavation and connecting the Aqua-Swirl inlet and outlet stub-outs with appropriate pipe couplings. Prior to shipping, the purchasing contractor provides written confirmation to install AquaShield products in accordance with manufacturer's specifications. Step 1 Excavation and Bedding The trench and trench bottom shall be constructed in accordance with ASTM D 2321, 6, Trench Excavation, and Section 7, Installation. The excavation pit is best positioned slightly offset of the center line of the incoming drain pipe trench because of the tangential inlet pipe connecting to the Aqua-Swirl. The Aqua-Swirl shall be installed on a stable base consisting of 12 inches of Class I stone materials (angular, crushed stone or rock, crushed gravel; large void content, containing little or no fines) as defined by ASTM D 2321, Section 5, Materials; and, compacted to 95% proctor density. All required safety precautions for Aqua- Swirl installation are the responsibility of the contractor. On-site excavation Step 2 Pipe Connection Devices Couplings to and from the Aqua-Swirl shall be supplied by the contractor and shall be Fernco, Mission or equal type flexible boot with stainless steel tension bands or equal. Using a metal sheer guard will protect the flexible connector. The coupling between the Aqua- Swirl and the pipe 4

Installation and Fabrication Step 3 Backfill Requirements Backfill materials shall be Class I or II stone materials, (well graded gravels, gravelly sands; content, containing little or no fines) as

Backfilling shall conform to ASTM F 1759, Section 4.2, Design Assumptions. Backfill shall extend at least 3.

Class I backfill material around the Aqua-Swirl Sufficient backfill shall be placed over components prior to using heavy compaction or construction equipment to prevent damage.

6 Installation and Fabrication Step 3 Backfill Requirements Backfill materials shall be Class I or II stone materials, (well graded gravels, gravelly sands; content, containing little or no fines) as defined by ASTM D 2321, Section 5, Materials; and, compacted to 90% proctor density. Class I materials are preferred. Backfill and bedding materials shall be free of debris. Backfilling shall conform to ASTM F 1759, Section 4.2, Design Assumptions. Backfill shall extend at least 3.5 feet beyond the edge of the Aqua-Swirl and for the full height to sub-grade and extend laterally to undisturbed soils. Class I backfill material around the Aqua-Swirl Sufficient backfill shall be placed over components prior to using heavy compaction or construction equipment to prevent damage. Support shall be provided for vertical risers as commonly found at service connections, cleanouts, and drop manholes to preclude vertical or lateral movement. Step 4 Traffic Loading A reinforced concrete pad shall be placed over the entire Aqua-Swirl when subject to H-20 (or greater) traffic loading. The pad shall extend no less than 12 inches beyond the outside diameter of the Aqua-Swirl. A professional engineer shall provide final approval of the design of the concrete pad and the calculations must be included in the submittal. Traffic rated foundry rims and covers shall be installed such that no contact is made between the HDPE access riser and cast iron frame. A reinforced concrete pad for H-20 traffic loading Step 5 Non-Traffic Loading Bollards shall be placed around access risers in non-traffic areas to prevent inadvertent loading by maintenance vehicles. 5

Installation and Fabrication Aqua-Guardian Installation Installation is a simple process of removing the surface grate cover and lowering the Aqua-Guardian into the catch basin.

However, removal and handling of the storm grate cover may require lifting equipment due to its weight and size.

21 Installation and Fabrication Aqua-Guardian Installation Installation is a simple process of removing the surface grate cover and lowering the Aqua-Guardian into the catch basin. Due to the lightweight nature of HDPE, the Aqua-Guardian units can be installed without the need for special lifting equipment. However, removal and handling of the storm grate cover may require lifting equipment due to its weight and size. The surface grate over an Aqua-Guardian unit The stainless steel support collar on the Aqua-Guardian is custom fitted to the inside the surface grate s frame. The flange on the stainless steel support collar will rest on the same rim that receives the surface grate cover. Once the insert is properly seated on the metal rim, replace the grate cover. The simple Aqua-Guardian installation without equipment 10
