4.6 La necesidad de crear conciencia de la realidad y optar por el pobre

The use of trenchless technology including relining applications outlined in Section 4 shall be carried out, and supervised by acceptable qualified and/or accredited personnel, who have successfully undertaken the following Units of Competence of the Civil Construction Training Package BCC30903.

“Successfully undertaken” shall mean “Statement of Attainment” for all those appropriate Units of Competence.

Only personnel who have successfully completed the above training programs shall be permitted to work on PE systems.

Certification details shall be carried by field personnel on-site, and be made available as required.

APPENDIX A

EQUIVALENT PIPE DIAMETERS

The following tables of equivalent pipe diameters have been produced to show the actual mean internal diameters of the CICL and AC water mains, laid extensively in the post World War II period to the mid 1970’s, compared to PE. Tables of equivalent pipe diameters with CICL and AC pressure pipes have been prepared from the pipe dimensions contained in Australian Standard Specification for Centrifugally Cast Iron Pressure Pipes for Water, Gas and Sewage (AS A145—1965) and Australian Standard Specification for Asbestos Cement Pressure Pipes and Joints (AS A41—1959). For CICL calculations, nominal values have been used, while for AC calculations, the internal diameters specified in the Standard were based upon minimum wall thicknesses. Class C CICL was most commonly used by Water Boards at that time, while for AC pipe individual Water Agency records should be consulted.

For pipe materials used since the late 1970’s consult current Australian Standards.

APPENDIX C STANDARD DRAWINGS C1 GENERAL

Standard Drawings that support Polyethylene Pipeline Code are included to assist understanding of the principles and methodology involved in construction of PE pipeline systems and to enhance the design and construction requirements of this Code and should be read in conjunction with them.

The Standard Drawings provide a “Deemed to Comply” solution for the installation of particular elements of a water supply or sewerage system that are specific to PE. Standard Drawings of other WSAA Codes should also be referenced as appropriate. However, the Drawings will not suit all circumstances or overcome all problems. To meet special needs, Designers and Constructors are encouraged to identify improved construction methods and other variations from the requirements set out in the drawings. Approval from local Water Agencies will be necessary before any major departures from the principles outlined in the drawings are implemented. Successful initiatives will be considered by WSAA for inclusion in future editions of this Code.

All Design Drawings should include the name of the Water Agency and have a signature block to allow confirmation that each drawing complies with Water Agency requirements.

The symbols and markings used on these Drawings are typical only and do not apply to any particular Water Agency (Refer to the individual Water Agency for their legend, symbol and layout requirements).

Individual Water Agencies may have specific information and presentation requirements, which should be determined before commencing any project. Any additional information, layout or format requirements specified by the Water Agency take precedence over these Drawings.

All special requirements including, but not limited to geotechnical requirements, embedment and compaction details, should be shown in the Design Drawings and/or the Specification.
