.        Distribution Network System:

·         Network:

The distribution network in Abu Dhabi made of more than 11,760 km of pipelines and the pipes are from 80 mm to 1200 mm diameter with 108 small to medium size tanks and 46 pump stations. The pipe work is mainly ductile iron, however lately high density polyethylene has been used instead of ductile iron.

·         Water Piping System:

There are three major components of a water piping system:

1. Primary feeders - water mains that are usually owned by a water company. Sizes -vary from 12” to 60” in diameter.

2. Secondary feeders - network of intermediate size pipes that interlace a grid system. Sizes - no smaller than 12” in diameter.

3. Distributors - pipes serve consumer blocks and feed individual hydrants. Sizes - should be no less than 8” and 12” on principle streets.

The water distribution network consists from

1-    Main pipe line -------  material DI

2-    Sector pipe line-------------------DI&HDPE

3-    Service pipe line -----------------material  Polyethylene  pipe ( MDPE & LDPE) means (low density & medium density polythene pipe)

4-    Boosting pump station to increase the pressure in the water system. 

 

There are more than 150 interface points available between Transco and ADDC through these points water is entering into the distribution system. ADDC is having only operational storage reservoirs in its system. Hence water is not residing in distribution system for a long time. In most of the distribution systems water is being delivered to the customers premise within hours after entering into the system. It is assessed that nowhere in the distribution system, water is residing more than 24 hours.

Conclusion:

 Cities with dense populations lack adequate fresh water because municipalities which should be supplying them are failing due to rising population and bad forecasting of population. I think ADDC is one of the best water distribution companies in the world. Because it can forecast the population growth and supply water for consumptions perfectly. People in Abu Dhabi should be grateful to the government because we get the cleanest water comparing to other countries.
