What is BS 9295 - structural design of buried pipelines about?  
Buried pipelines are required to withstand internal hydrostatic pressure, external loads from the soil, surcharge, and traffic and are required to be safe against buckling. BS 9295 discusses the structural design of buried pipelines.
BS 9295 gives information and guidance for the use of BS EN 1295‑1:1997, National Annex A, the UK established method for the structural design of buried pipelines under various conditions of loading. The procedures are explained and, for situations where general assumptions can be made, loading tables are given.
Note 1: The scope of BS EN 1295‑1:1997 is restricted to the structural design of water supply pipelines, drains and sewers, and other water industry pipelines, whether operating at atmospheric, greater, or lesser pressure.
Note 2: The design for longitudinal effects is not covered (see BS EN 1295‑1:1997, 5.4).
Who is BS 9295 - structural design of buried pipelines for? 
BS 9295 on the structural design of buried pipelines is useful for: 
- Relevant government / municipal authorities
- The water board responsible for the supply and distribution of drinking water
- Manufacturers and suppliers of pipes and components
- Designers of pipes and components
- Civil / construction engineers
- The process industry
- The construction industry
- Quality control personnel
- Builders / architects / real estate developers
Why should you use BS 9295 - structural design of buried pipelines?  
The structural design of buried pipelines constitutes a wide-ranging and complex field of engineering, which has been the subject of extensive study and research, in many countries over a period of very many years.
The aim of BS 9295, therefore, is to consolidate and update the various documents that together describe the UK method.
BS 9295 gives further information on the structural design of buried pipelines under various conditions of loading using the established UK method. BS 9295 consolidates and updates the various documents that together describe the UK method.
BS 9295 is a key standard for anyone in the construction industry that designs or builds water supply systems, drains, sewage systems, and underground pipes.
BS 9295 specifies the requirements for structural design and indicates the references and the basic principles of the nationally established methods of design.
In addition, BS 9295 gives guidance on the application of the nationally established methods of design declared by and used in CEN member countries at the time of preparation of BS 9295.
The purpose of the structural design of the cross‑section of buried pipelines is to ensure that they are designed so that the optimum materials and embedments are selected for the given installation, whilst meeting all the necessary design criteria.
Overall, BS 9295 could help you design pipelines that enable a variety of pipes to be assessed for the suitability of their structural performance when buried in trenches or embankments ensuring the strength, elasticity, and longevity of pipes.
