Brief About Water Connection Components




Components generally include a usage meter; a service feed pipe, water heater and a distribution system.
In a public water system, the public utility provides water supply through a water main and service line to the edge of the public right-of-way, where the water usage meter is located. The service feed pipe from the structure then connects to the usage meter. For structures connected to public water sup- ply, only the service feed pipe and the on-site distribution system are covered in this manual.

In an on-site water supply system, the source of water is a private on-site well, and the owner is responsible for the operation and maintenance of the well. The water service feed pipe is the main pipeline that connects the on- site water well to the distribution system within a structure. The distribution system includes the pressure tank and all the pipes and water delivery accessories (faucets, showers, etc.) in a structure.

The two main dangers that floodwaters present to water supply systems are:

1. Damage to pipes and to the on-site well head from the effects of velocity flow, wave action, and debris impact.

2. Water supply contamination in the well, service feed pipe, and distribution system.


In general, the figures in this chapter attempt to illustrate some general prac- tices that meet the requirements of the National Flood Insurance Program (NFIP). Local codes and health/sanitary regulations permit many variations that also meet NFIP regulations. Please refer to your local code officials for specific practices that may meet both the NFIP regulations and local code.
