Answer 2

The different water samples are:

• Samples should be taken from areas representing water source, treatment plant, storage facilities, distribution network, areas where water is delivered to the consumer, and use areas.

• When selecting sample points, each area should be considered separately.

The following criteria usually apply:

• Sample points should be selected in such a way that the samples taken represent the various sources from which water is obtained from the community or enters the system.

• These points should include those that produce samples that represent conditions in the wrong sources or areas in the supply system, especially points that may be contaminated such as unsafe sources, loops, dams, low pressure areas, system endings, etc.
• Sample points should be evenly distributed throughout the pipeline distribution system, taking into account the distribution of people considering the number of sample locations should be equal to the number of links or branches.

• Selected points should usually reflect samples that represent the entire system and its key components.

• Sample areas should be positioned so that water can be taken from the designated tanks and dams, etc.
