Scope

1.1     

This Standard addresses considerations for adapting wastewater treatment plants (existing, new, or retrofit/upgrade projects) to a changing climate by reviewing climate, regulatory, risk, design, construction, and operations and maintenance aspects.

1.2     

This Standard provides a user-friendly framework and tool for designers, engineers, and managers to use when designing, constructing, or operating/maintaining WWTPs.

Note: The intention is to provide guidance for extrapolating the use of the tool for other infrastructure projects to assess risk (related to climate change) and rank and prioritize actions to build-in resiliency, redundancy or contingency plans, without indiscriminate overdesign.

1.3   

This Standard provides guidance on climate change data sources and their usage in determining the impacts on wastewater treatment plants components.

1.4     

This Standard highlights climate change adaptation measures for building resilience and addressing high risk scenarios.

1.5     

This Standard applies to the wastewater treatment plant itself, its processes, and property. It does not apply to collection systems feeding into the plant or to disposal receivers.

1.6     

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.

Scope

1.1
This Standard covers polybutylene (PB) pipe, tubing, and fittings. Nominal pipe sizes (NPS) covered are NPS-1/4 to NPS-2. Fittings covered include insert-type fittings, socket fusion fittings, plastic-to-metal transition fittings, and compression-type fittings. Pipes, tubing, and fittings covered by this Standard are intended for use in pressure applications such as hot and cold potable and non-potable water distribution systems operating at a maximum pressure of 690 kPa and at a maximum temperature of 82 °C.

This Standard provides the definition of the term “park model trailer” as used in the CSA Z241 Series. It also gives general safety requirements that apply to the other Standards in this Series.

Scope

This Code applies to the design, evaluation, and structural rehabilitation design of fixed and movable highway bridges in Canada. There is no limit on span length, but this Code does not necessarily cover all aspects of design for every type of long-span bridge. This Code also covers the design of pedestrian bridges, retaining walls, barriers, and highway accessory supports of a structural nature, e.g., lighting poles and sign support structures.

This Code does not apply to public utility structures or to bridges used solely for railway or rail transit purposes.

This Code does not specify requirements related to coastal effects (e.g., exposure to sea action and icebergs) or to mountainous terrain effects (e.g., avalanches). For structures that can be subject to such effects, specialists need to be retained to review and advise on the design and to ensure that the applicable requirements of other codes are met.

For bridges not entirely within the scope of this Code, the requirements of this Code apply only when appropriate. Necessary additional or alternative design criteria are subject to the Aapproval by the Owner.

Scope

This Section specifies requirements for the design of conventional movable highway bridges, i.e., bascule (including rolling lift), swing, and vertical lift bridges and deals primarily with the components involved in the operation of such bridges. The requirements for fixed span bridges, as given in other sections of the Code, shall apply to movable bridges, except as otherwise provided.

Scope

This Section specifies minimum requirements for the rehabilitation of bridges but is not applicable to the resolution of construction deficiencies of new structures. The requirements specified in this Section relate only to condition assessment, loads, load factors, resistances, and other design criteria relevant to the rehabilitation of bridges including required remaining service life, and assessment of ongoing deterioration and its impact on structural integrity.  Material specifications,  and rehabilitation procedures and maintenance procedures are not covered in this Section. but should conform to accepted Canadian good practice.

Scope

This Section specifies loads, load factors, and load combinations to be used in calculating load effects for design. Resistance factors required to check ultimate limit states criteria in accordance with Clause 3.4.2 are specified elsewhere in this Code. Loadings provisions for evaluation of existing structures are covered in Section 14 and for rehabilitation in Section 15.

This Section includes requirements related to the vibration of highway and pedestrian bridges. It also includes requirements related to construction loads and temporary structures; these apply to partially completed structures and structures necessary for construction purposes. Snow loads are not specified because in normal circumstances the occurrence of a considerable snow load will cause a compensating reduction in traffic load.
