How is water distributed?
Water is distributed to the consumer in several different ways. The methods are. Direct pumping. In this method the pumps force water direct into the mains with no other outlet than the water actually being used. It is a least desireable system as a power failure would result in the no availability of water. As consumption varies so pressure in the ...
Why is water a least desireable system?
It is a least desireable system as a power failure would result in the no availability of water. As consumption varies so pressure in the mains is likely to fluctuate. To fulfil the varying consumptions, several pumps are available to add water output when needed. This requiring constant attendance of electricity.
Why is gravity distribution reliable?
This method is fairly reliable. Because the stored water may be use at any time when there will be a sudden power failure. Gravity distribution. This is possible when lake or reservoir is at some elevation above the city so that sufficient pressure can be maintained in mains for domestic and fire purposes.
How long does filtered water last in a distribution system?
The capacity to store filtered water corresponding to 14 to 16 hours of average daily flow for storage when pumps are idle.
What is the source of water in a gravity system?
In the gravity system, the source of water supply is so located with respect to the area of distribution that water is available with sufficient pressure at various points of the area. No pumping is normally required.
What is water distribution system?
Water distribution systems consist of an interconnected series of components. They include: Water distribution systems meet fire protection needs for: Public water systems depend on distribution systems to provide an uninterrupted supply of pressurized safe drinking water to all consumers.
Why do public water systems depend on distribution systems?
Public water systems depend on distribution systems to provide an uninterrupted supply of pressurized safe drinking water to all consumers. Distribution system mains carry water from either: the source to the consumer when treatment is absent. Distribution systems span almost one million miles in the United States.
Why are new pipes added to water distribution systems?
New pipes are added to distribution systems as development occurs. The additions result in a wide variation in: As these systems age, deterioration can occur due to corrosion, materials erosion, and external pressures. Deteriorating water distribution systems can lead to:

Distribution systems span almost one million miles in the United States. They represent the vast majority of physical infrastructure for water supplies. Distribution system wear and tear can pose intermittent or persistent health risks.
Introduction
The water distribution system objectives to distribute water to the consumer with proper quality, quantity, and pressure. It is used for describing the water distribution facilities used to supply water from the source to the point of usage.
Types of Water Distribution System

Methods of Water Distribution System
For an effective distribution system, suitable water pressure is required at various points.
What are the requirements for water distribution?
This requires the water supply system to be water-tight. Water head at the consumer tap should be sufficient. Larger pressure requires smaller diameter pipe and vice versa.
How is water supplied in a ring system?
Water is supplied through radially laid pipelines.
Why is there more wastage in intermittent water systems?
Some say that wastage is more in intermittent systems because consumers leave their taps open during non-supply hours. It is possible that water may not be required but remains flowing causing lot of wastage. Old water may be thrown out to waste and changed with fresh water in storage tanks.
What is intermittent water supply?
6) Intermittent system. Water is supplied to consumers only during fixed hour continuously for 24 hours a day. It is the most ideal system and as far as possible, should be adopted. But this system is possible only when there is sufficient quantity of water available from the source.
