Grit Chamber:

The raw water collected from the source and transported through the water transmission line carries with its coarse particles that were not retained in the inlet screening. These particles such as sand must be removed by means of a sand trap so that they do not affect the processes in the treatment plant.

Pondage or Raw Water Reservoir:

When water storage is required to maintain a normal water supply during peak periods or dry seasons, the installation of a pondage or a reservoir is considered to store raw water. Alternatively, ponding helps to regulate the quality of raw water with high sediment content in rainy seasons.

Pumping:

It is the technique by which through a pump that absorbs mechanical energy and transfers hydraulic energy to move the water. It is used when, due to the difference in heights between the starting and ending points, the transport cannot be done by gravity. This may be because the difference in elevation between the starting and ending points is very low, producing small flows, or because the end point of the section is higher than the starting point.
