At the sedimentation pool calcium is again added and the water is sent to the lakes where it will sit for some time.

The soild wastes collect on the surface and are continuously removed until the water is fit to be released into the river.

The ph of the water can be from 5/7.5 when it first arrives to the sedimentation pool.

Once it is ready to leave the lakes and be released to the lakes it is only 4/5. the above photo is the first of two sedimentation lakes that Coope El Dos has.
