These arise from the sludge that is removed from septic tanks and emptied<br />

onto sludge dry beds. While on the beds, they pose high risks of infiltration<br />

into ground water and nearby streams. Air pollution arising from the foul<br />

smells and odors poses a threat to the nearby residents as well as rodents and<br />

vectors. Chogoria hospital has a well functioning sewage plant.<br />

3.3.3 Waste Disposal facilities<br />

The following are methods used or can be used in the <strong>District</strong> to dispose off<br />

various wastes.<br />

Incineration<br />

This method uses fire and is aimed at sterilizing the refuse to significantly<br />

reduce the volume so that the residue can be disposed off hygienically and<br />

economically as clinkers, ashes and gas.<br />

Sanitary land filling (controlled tipping)<br />

This is a system of disposing of refuse by tipping or dumping in a methodical<br />

manner (as distinct from crude or indiscriminate manner).<br />

Crude dumping (Indiscriminate Disposal)<br />

This is the method adopted mostly in the <strong>District</strong> and involves solid disposal<br />

in a manner that disregards any precautions either in a specific chosen area or<br />

dumped anywhere in the open. This method of disposal causes a lot of<br />

nuisance and many health hazards arise as a result of their decomposition.<br />

Composting<br />

This is an aerobic biological process in which decomposition degrades<br />

susceptible organic materials (O.M.) into CO2, HO2 and stable humus like<br />

substance called compost is left which can be used in the farm.<br />
