Potable Water

A well-functioning, public fresh water supply is a vital component in the modern industrial world. Availability of water in the necessary quality and quantity is the basis for human well-being and economic development.

Some factors are affecting today a modern potable water and distribution plant:   

	Regulatory. Legislation intend to protect human health by laying down healthiness and purity requirements which must be met by drinking water. Need to comply to lower parametric and to improve monitoring to collect different parameters.
	Treatment. After falling as rain, water flows through various path of the hydrologic cycle and the route through this cycle determines the kind of pollutants which became suspended or dissolved. Treatment process that performs the removal of the pollutant to obtain a water quality according to legislation demands, need to be controlled
	Quantity and Availability. Not only the quality of water but also the quantity available for human use is of importance. Quantity of water delivered need to be matched with the availability of single sources, avoiding stress from one side and shortages on the other. Reducing leakage in the distribution network is also required.
	Security. Contamination that causes long-term shut down of a major segment of water supply can result not only in economic losses in the community, but health problems for the public. Utilities, depending upon the assessment of risk reduction, may find it appropriate to establish monitoring systems capable of detecting contaminants in the water to mount an appropriate response that would protect the public health and safety.
	Business Factors.  Potable water treatment and distribution, independently if is run by a private or a municipal utilities, is a business sector where investment, cost and profit are actively managed  to achieve the lowest  cost of the service, that is the key competitive factor, especially in the country where this industry is deregulated. Investment in automation and control are done to reduce operating cost such as energy, reagents increasing the efficiency of system.

Measurement and process automation located at source, treatment and distribution process play an important role to achieve in an efficient way all of these objectives.

Endress+Hauser takes up the challenge as a leading producer of measurement applications and offers to Potable Water Industry its complete line of analyzers for chemical parameters such as Alluminium, Chlorine, Iron, Manganese, TOC  and a wide range of products and instruments to measure pressure and flow, which has recently been completed with low price ultrasound measurements.
