1. Water Supply:
Predicting demand for water, impurities of water and their significance, physical, chemical and bacteriological analysis,
waterborne diseases, standards for potable water.
2. Intake of Water:
Water treatment: principles of coagulation, flocculation and sedimentation; slow-, rapid-, pressure, filters; chlorination,
softening, removal of taste, odour and salinity.
3. Sewerage Systems:
Domestic and industrial wastes, store sewage—separate and combined systems, flow through sewers, design of sewers.
4. Sewage Characterisation:
BOD, COD, solids, dissolved oxygen, nitrogen and TOC. Standards of disposal in normal water course and on land.
5. Sewage Treatment:
Working principles, units, chambers, sedimentation tank, trickling filters, oxidation ponds, activated sludge process,
septic tank, disposal of sludge, recycling of waste water.
6. Solid waste:
Collection and disposal in rural and urban contexts, management of long-term ill-effects.
