What is BS EN 15383 – GRP UP Manholes and inspection chambers about?  
Drain and sewerage piping systems need to be designed with materials that can meet the force and displacement requirement to accommodate a safe operation. BS EN 15383 is a European Standard that is a system standard for manholes and inspection chambers made for plastics piping systems using glass-reinforced thermosetting plastics (GRP) based on the polyester resin (UP) for drainage and sewerage.
BS EN 15383 applies to:
- Manholes, when made from GRP UP
- Inspection chambers, when made from GRP UP
that are intended to be used with inverts that are at a depth not exceeding 2 m.
BS EN 15383 applies to products, and their joints, intended for use in buried installations and to be installed by open-trench techniques.
Who is BS EN 15383 - GRP UP Manholes and inspection chambers for? 
BS EN 15383 on GRP UP manholes and inspection chambers is useful for: 
- The plastics / thermoplastics industry
- Relevant government / municipal / local authorities
- Sewer and drainage system planners and designers
- GRP Up pipe / fittings / components manufacturers
- Product design engineers
- Quality control and testing personnel
- Contractors / supervisors / plumbers
- Real estate developers / Estate managers / architects
- Civil / construction engineers
- Maintenance teams
- Health and safety bodies
Why should you use is BS EN 15383 - GRP UP Manholes and inspection chambers? 
A good subterranean drainage system requires manholes and inspection chambers. Inspection chambers offer simple access to the sewage for cleaning and maintenance.
BS EN 15383 guidelines help you to design and manufacture GRP UP manholes and inspection chambers that are intended to be used within a drain or sewer system operating without pressure or occasionally at ahead of pressure up to 1 bar.
The intended use of these GRP UP manholes and inspection chambers is to provide access to buried drain or sewer systems for the conveyance of wastewater at temperatures up to 50 °C, without pressure or occasionally at ahead of pressure up to 1 bar, outside buildings and installed in areas subjected to the vehicle and/or pedestrian traffic.
BS EN 15383 specifies the definitions, symbols, requirements, and characteristics of manholes, inspection chambers, joints, and materials. BS EN 15383 also guides you with test methods and marking for these GRP UP manholes and inspection chambers.
BS EN 15383 is guidelines help you to provide a big enough entry point into sewer or storm drain systems for users to enter and execute self-inspection and cleaning processes. BS EN 15383 guidelines help you to follow best practices for designing and manufacturing GRP UP manholes and inspection chambers so that underground pipes, wires, drains, and sewers can be safely examined, maintained, and cleaned.
