Water Distribution System Operation and Maintenance

Objective

This course trains operators to safely and effectively operate and maintain water distribution systems.

Scope

This course trains operators in the practical aspects of operating and maintaining water distribution systems, emphasizing safe practices and procedures. Topics include water distribution system operator duties; procedures for operating and maintaining clear wells and storage tanks; components and characteristics of distribution system facilities; operating and maintaining distribution systems; maintaining water quality in the system; disinfecting new and repaired facilities, as well as water delivered to consumers; and techniques for recognizing hazards and developing safe procedures and programs. The Chapter Review at the end of each chapter gives operators the ability to self-assess their understanding of the material by answering fill-in, matching, and multiple-choice questions.

Contemporary cities and their inhabitants depend on a reliable and generous public water supply system for their functioning, and in order to protect and promote health, productivity and well-being. In fact, the possibility of having piped water and sewerage systems at home is an explanation why cities can support so huge human concentrations. Some mayor technological and cultural changes, to make cities less dependent of such public services, are needed but still far in the future. These vast systems, almost invisible to many as they are underground networks, are complex and delicate arteries that require daily operation and care by professional people devoted exclusively to such tasks.

What are the three major components of a water distribution system?

Fundamentally, a water supply system may be described as consisting of three basic components: the source of supply, the processing or treatment of the water, and the distribution of water to the users.

What is the process of water distribution?

Pipelines laid within public right of way called water mains are used to transport water within a distribution system. Large diameter water mains called primary feeders are used to connect between water treatment plants and service areas. Secondary feeders are connected between primary feeders and distributors.

What are the 2 types of water distribution systems?

In order to achieve this, four main water distribution system types are used:.

Gridiron systems. In gridiron systems, the main water supply line goes through the central part of the area, while sub mains branch out perpendicular to the main line. ... .

Ring systems. ... .

Radial systems. ... .

Dead-end systems..

What is the purpose of water distribution system?

The basic function of a water distribution system is to transport the water from the treatment facility to the customer. In addition, distribution systems may also provide storage, as well as provide flow and pressure adequate for fire protection.
