Estimating the total water demand for the industrial city in Hasia

الملخص

This research includes a detailed survey of the existing factories in the industrial city in Hasia, in addition to the administrative and service activities, in order to identify the actual water needs and the design water needs of the facilities and activities included in the survey, and the quality of the water required for use.

This research aims to determine the standard needs of each type of industries and other events in the industrial city, leading to an estimate of the amount of total water needs for the industrial city when it is fully invested, and to determine the quality of the required water.

The research reached to determine the standard need for water in industry at about 26,399 m³/year/hectare that varies according to the type of industries: food 44476 m³/year/ hectare, textile 35588 m3 / year / hectare, chemical 14178 m³ / year / hectare, engineering 11355 m³ /year/ Hectare. As for the standard need for water in administrative and service activities, it amounted to 1805 m³ /year/ hectare. In terms of water quality, the percentage of fresh water required for industrial use reached 82.39% and varies according to the type of industry, ranging from 29% in the chemical industries to more than 99% in the food industries. As for the expected total water need for the city, it was estimated at 24.436 million m³/year, of which 19.360 million is fresh water and the rest is non-fresh water. The research also found that the current water source, which can provide the city with up to (6) million m³/year, is insufficient.

At the end of the research, several Proposals were made to secure the required quantities of water in terms of quantity and quality in the short and long term, in order to ensure the provision of the city's water needs in a reliable manner commensurate with the large industrial investments made in it.
