This Appraisal is for a range of PVC-U sewer maintenance shafts, including associated fittings. The sewer maintenance shafts provide a safe alternative to traditional access chambers to enable access for maintenance and CCTV cameras. This Issue 2 is a replacement for the previous appraisal which had reached its 5-year expiry date.

The basic types of Aymroo PVC-U sewer maintenance shafts are summarised below:

  • DN 300 “T” section body with inline, junction or bend configurations.

          Junctions may be at 45° or 90°. Bends may be specified from 5° to 90°.

  • DN 300 terminal maintenance shaft.

          This maintenance shaft utilises a DN 300 bend.

  • Central Axis Maintenance Shaft (CAMS)

          This maintenance shaft is specifically designed for improved hydraulic performance and camera access and is manufactured by welding a moulded base and top together. The maintenance shaft can be supplied with inlet angles from 80° to 280° from the outlet,                 an  inlet grade from 0° to 15° and an inlet invert level height from 0mm up to 650mm.

Solvent cement joint level invert tapers may be utilised to provide inlet and outlet sizes of DN 100, DN 150, DN 225 or DN 300 and riser sizes of DN 225 or DN 300 for all MS types. The CAMS facilitates connection to DN 150 and DN 225 inlet and outlet sizes.

The Aymroo maintenance shafts are suitable for installation depths up to 4.7 metres.
