3350 or walls greater than 63" OD shall be
fabricated from profile wall HDPE ASTM F
894 RSC 250.
3. HDPE stub outs and internal components
shall be extrusion welded using accepted
welding practices. Stub outs shall be
supplied by Manufacturer and welded on
inside and outside.
4. Manufacturer shall supply direct access to
Swirl Concentrator via 30 -inch ID riser(s),
which can be field cut to match finished
grade by Contractor.

rated 1120)
03 -20 -03
8. Where traffic loading (H -20) is required or
anticipated, a reinforced concrete pad must
be placed over the entire Swirl Concentrator
per concrete design as calculated by
Engineer. Sample of typical concrete design
detail is available upon request.
9. Bollards shall be placed around access
risers in non traffic areas to prevent
