As the largest comprehensive industrial city and foreign trade port in China, Shanghai has a gross industrial output value accounting for one eighth of the country’s total. Its port throughput accounts for about two-fifths of the national total. It occupies an important position in the country’s economic development. Over the past 30 years With the development of industrial and agricultural production and urban construction, the water consumption of the whole city increased rapidly.
