The population records of Al-Zubair city center are as given below. Answer the
followings:
Year
2010
2011
2012
2013
2015
Population 435546 447982 459800 471894 496923
1- Find the population growth rate of this city assuming arithmetic growth method.
2- If it is required to design a water treatment plant to serve the city till the year
2050, find the plant design capacity assuming the total average water demand for
domestic and public uses is 400 liter/capita/day and the percent of water loss is
20%. Also, find the maximum hourly water demand and fire demand of the city in
the year 2050.
3- Estimate the yearly consumption of alum for the proposed water treatment plant
using the results of Jar test given below:
4- Determine the number of alum solution tanks, if the used tanks have a capacity of
50m³.
5- If the natural alkalinity of the water source is 6mg/l do we need to add alkalinity?.
If we must add alkalinity, select the type of added alkalinity and estimate its
monthly requirement.
