Let's get rid of Non-revenue water (NRW) from National Water Supply and Drainage Board (NWSDB)
Non-revenue water (NRW) might be referred to as the gap between the amount of water that's placed into a water system and therefore the volume of water that's beaked as licensed consumption. NRW could be a major concern to any or all the water utilities around the world since it affects water distribution systems. apart from a restricted range of Asian cities, several cities have visage this development severely. Colombo is taken into account because the industrial capital of the state and presently, the NRW proportion of Colombo town has exceeded 52% that indicates that from the entire quantity of water equipped to the Colombo town, quite 52% of the water that is equipped won’t generate revenue to the National Water Supply and Drainage Board (NWSDB).
These issues
square measure thanks to the complexness of this pipeline system NWSDB faces
such a big amount of issues particularly once it involves the upkeep and
repairing of those pipeline systems. With fast urbanization, the availability
of safe drinks to urban communities has become a very important and difficult
task of governments in developing countries. In-state, water to urban areas as
well as Colombo town is provided by NWSDB. NWSDB spends giant amounts of cash
annually to supply and distribute safe drink to the entire state NWSDB has
metered all water connections and charges a fee from every water consumer,
supported the water volume they consume. However, some of the water produced by
the NWSDB is lost within the water system. This can be referred to as
Non-Revenue Water (NRW) as there's no revenue generated for the water loss
within the system. several urbanized Asian cities, as well as Colombo, have
high NRW levels inflicting a giant loss of revenue to water operators. thence
it ought to be thought of as a significant national downside.
NRW will
happen via many suggests that they can be listed as,
·
Physical
losses
·
Commercial
losses
·
Unbuilt
licensed consumption
Following ways were wont to cut back the generation of NRW,
·
Replace
the system input volume (SIV) meters with magnetic force meters for remote
reading.
·
Rehabilitation
of the water distribution network by replacement forged iron (CI) pipes, larger
diameter pipes, reinforcing pipes, and more.
·
Replacement
of defective water meters. (Bulk meters and shopper meters)
·
Calibration
and change of the GIS network.
·
Implement
Active outpouring management policies, speed, and quality of the repairs.
·
Pressure
management inside the water distribution system.
·
Introduce
the District Metered space system bit by bit.
·
Attend
the criticism terribly effectively.
NRW
generation won't solely occur throughout the distribution of water to the top
customers by the accountable authorities. It may occur throughout the storage
of water and whereas distributing water bulks through the reservoirs. Even the
conduct of effective awareness programs inside the society will increase the
amount of NRW proportion reduction.
