The American Water Works Association has published standards for materials used in the field of fire protection for many decades. Preface Water distribution systems have awwa m31 developed and operated for a variety of reasons. When the governing body of a community makes a conscious decision to use awwa m31 available water supply system for fire suppression purposes, this manual should be consulted, judiciously awwa m31, and tempered as local conditions require.

As was the case with the first edition, this awwa m31 edition does not intend to describe how firefighters should use water to control fires, but rather how water utilities should design and operate their systems to maximize fire protection benefits while delivering safe, potable water to customers. The water utility must work together with local fire officials, building code officials, and others to effectively and efficiently promote fire protection. Chapter 3 focuses on distribution storage in terms of both sizing and location.

In many cases, the water systems established to provide potable water were augmented and enlarged to provide water for irrigation, car washing, industrial processes, and other purposes.

Speed up research, capture and reuse expertise For additional product information, visit the IHS Standards Expert page. This manual provides specific guidance on the design, operation, and maintenance of water distribution systems as awwa m31 relate to fire protection and fire suppression activities.


This edition of the awwa m31 updates the information, clarifies some topics, and deletes material that is no longer essential.

Top Categories Terms of Use. Identify unmet needs and discover next-generation technologies Improve quality by leveraging consistent standards to meet customer and awwa m31 requirements Minimize risk: Systems that provide for fire protection needs have frequently been incorporated into the systems that provide potable water service as well as awwa m31 service. The manual still closely parallels the first edition prepared by the Fire Protection Committee. awea

However, it was not until the early s that AWWA’s M13 on Fire Protection developed the first edition of this manual, which addresses the planning, design, and maintenance of distribution systems that supply water awwa m31 fire protection and suppression. Price and Buy this Standard View Pricing.

Chapter 1 describes several methods for determining required fire flows. Click here to skip or ad will close in 15 seconds. Appendix A lists organizations involved in fire protection and describes adwa organizations awwa m31 their roles. It also became necessary awwa m31 provide an adequate supply of water for fire protection and suppression.

The need for nonpotable water arose because of an increasingly sophisticated lifestyle. Water distribution systems have been awwa m31 and operated for a variety of reasons. IHS Standards Expert subscription, simplifies and expedites the process for finding and managing standards by giving you access to standards from over standards developing organizations SDOs.

Awwa m31 agencies or private enterprise promptly took on the responsibility of providing safe water to meet these basic human requirements. The adequacy of a water distribution system for fire protection depends on the fire flows required. Chapter 2 discusses the impact awwa m31 fire protection on distribution system design.


Mitigate liability and better understand compliance regulations Boost efficiency: As technology advances, many alternatives to this basic water supply configuration can be found.

Appendix Awwa m31 describes the relationship between the water supply system and fire insurance ratings, because one benefit of supplying needed fire flow is an improved fire insurance rating for a community.

The water utility has awwa m31 partners in fire protection.

This standard is available for individual purchase. Awwa m31 communication between all involved parties is essential to protect property and life.

A notable alternative is the use of dual distribution systems. Awwa m31 4 discusses reliability issues arising because systems must awa in operation even when individual components are out of service. The emphasis is on public water systems and not on water systems exclusively designed for fire protection.

Chapter 5 describes fire suppression sprinkler systems and their effect on water requirements, particularly because they affect aww water is used for fire fighting.

In awwa m31 past, many awwa m31 recognized the need for safe, potable water that could be used for drinking and cooking. Once fire flow requirements are determined, these are added to the other water system demand requirements.
