Overview — BS 8558 (surface water drainage guidance)

BS 8558 is British Standards guidance supporting the design, installation and maintenance of sustainable drainage systems (SuDS) and conventional surface water drainage for new developments. It interprets and expands on the principles in BS EN 752 and provides recommended good practice for planners, designers, contractors and maintainers.

3. Core Technical Content (Deep Dive)

What is BS 8558?

BS 8558:2015 (which superseded BS 6700:2006+A1:2009) is titled "Guide to the design, installation, testing, operation and maintenance of services supplying water for domestic use within buildings and their curtilages."

Unlike prescriptive codes that tell you exactly what measurement to use, BS 8558 acts as a best-practice guide. It bridges the gap between the Water Supply (Water Fittings) Regulations (often referred to as the Water Byelaws) and the European standard BS EN 806. bs 8558 pdf

Why is BS 8558 Critical for Modern Water Systems?

Over the last decade, the water industry has faced two major challenges: lead in plumbing and Legionella control. BS 8558 directly addresses both.

Scope and purpose

  • Provides guidance on planning, design, construction and maintenance of surface water drainage for developments up to and including minor drainage systems (private drains, gullies, pipework) and SuDS elements (attenuation basins, swales, permeable paving, infiltration).
  • Helps designers translate technical standards (e.g., BS EN 752) into practical, site-specific solutions.
  • Aims to manage flood risk, protect receiving waters, reduce pollution, and provide amenity and biodiversity benefits where possible.

Warning: Do not use the withdrawn BS 6700 PDF. While similar, BS 6700 does not reflect current Legionella control or lead pipe replacement guidance. Overview — BS 8558 (surface water drainage guidance)

2. Legionella Risk Management (L8)

Health & Safety Executive (HSE) guidance (often called ACoP L8) references BS 8558 for technical water system design. The standard details:

  • Maximum dead-leg lengths (the distance from the circulation loop to the outlet).
  • Temperature maintenance (hot water stored at 60°C and distributed at 50°C+).
  • Flushing protocols for pre-commissioning.

Q4: What is the difference between BS 8558 and BS 8515?

A: BS 8515 specifically covers rainwater harvesting systems. BS 8558 covers the entire water supply system but contains a chapter referring to BS 8515 for rainwater details. Official Sources for BS 8558 PDF:

1. Introduction: Why “BS 8558 PDF” is a Common Search

Engineers, plumbing designers, and building services professionals frequently search for a “BS 8558 pdf” because this standard is a cornerstone of UK water hygiene and safety. It is the successor to BS 6700 and, together with the Water Supply (Water Fittings) Regulations 1999, forms the technical backbone for domestic water services in buildings.
