The said town has population of 720,000 today. A wastewater treatment plant is to be designed and constructed to cater for population of till 2051. You can design the required wastewater treatment plan in phases of 10 years.  Each town has one high school and one 50 bed Hospital for each 100,000 of population. Add commercial wastewater of 2 mgd for each 100,000 population equivalent. Following is required: 1.Suggest at least three options for siting the plant 2. Map showing sewerage system lines for effective sewage collection 3.Type of wastewater treatment plant the will be most economical 4.Size of each unit operation / reactor 5.Expected quality of the wastewater after each treatment unit 6.List re-use options for treated wastewater 7.Will the treated wastewater be sufficient for fir demand of the respective town.

Integrated Solid Waste Management

Integrated Solid Waste Management (ISWM) is a thorough waste suppression, compost, removal and recycling Program. An effective ISWM system considers how to suppress, manage and recycle solid waste in a manner that is most efficiently to protect human health and the surrounding. ISWM system requires evaluation of public wants and demands and then selecting and merging the most effective waste management activities for the proposed demands. The main ISWM activities for solid waste management are Waste prevention, Recycling and Composting, and Combustion and Removal and waste collection in a properly planned, constructed, managed and mitigated landfill areas. Each of these requires careful designing, financing, accumulation, and delivery of activities.
