What is BS EN 1508 – Requirements for service reservoirs for water storage about? 
BS EN 1508 is a European Standard that discusses water supply systems. The main aim of BS EN 1508 is to provide best industry guidance on systems and components used for the storage of water, such that they play a positive role in preventing contamination of drinking water.
BS EN 1508 specifies and gives guidance on:
- General requirements for storage of water outside consumers’ buildings, including service reservoirs for potable water and reservoirs containing water not for human consumption at intake works or within treatment works, excluding those that are part of the treatment process design
- General requirements for product standards
- Requirements for checks, testing and commissioning
- Operational requirements
- Requirements for rehabilitation and repair
The requirements of BS EN 1508 are applicable to:
- The design and construction of new reservoirs
- The extension and modification of existing reservoirs
- Significant rehabilitation of existing reservoirs
Who is BS EN 1508 – Requirements for service reservoirs for water storage for?  
BS EN 1508 on requirements for systems and components for the storage of water  is relevant to: 
- Anyone involved in design, construction, commissioning, rehabilitation, repair and operation of reservoirs
- Manufacturers, designers and suppliers of main valves, pumps, controls and monitoring equipment used in reservoirs
- Quality control and testing authorities
- Local bodies
- Local and national regulatory authorities
Why should you use BS EN 1508 - Requirements for service reservoirs for water storage?  
In specifying the requirements of this standard, due regard has been taken of the importance of a reliable and safe supply of water for human consumption as well as for the purposes of trade, industry, agriculture and fire fighting. The widely varying water supply legislative requirements, populations, social and climatic conditions across Europe have also been taken into account.
BS EN 1508 is written principally for application to service reservoirs.
BS EN 1508 provides best industry guidance on functional and design requirements that ensure adequate watertightness and the structural design complement the operationality and efficiency of the water supply systems. Rehabilitation and repair requirements are also discussed.
Guidance on appropriate manufacturing checks, testing and commissioning is also covered in BS EN 1508.
Thus, BS EN 1508 can ensure the reservoir is fit for its purpose, such that no contamination of water takes place. As a result, potential health risks arising from consumption of polluted water can be avoided.
