Risks and problems associated with solid wastes If solid wastes are not managed properly, there are many negative impacts that may result. The relative importance of each depends very much on local conditions.
Uncollected wastes often end up in drains, causing blockages which result in flooding and insanitary conditions.
Flies breed in some constituents of solid wastes, and flies are very effective vectors that spread disease.
Mosquitoes breed in blocked drains and in rainwater that is retained in discarded cans, tyres and other objects. Mosquitoes spread disease, including malaria and dengue.
Rats find shelter and food in waste dumps. Rats consume and spoil food, spread disease, damage electrical cables and other materials and inflict unpleasant bites.
Waste that is treated or disposed of in unsatisfactory ways can cause a severe aesthetic nuisance in terms of smell and appearance. Liquids and fumes, escaping from deposits of chemical wastes.
