GES provides a very affordable service to build WWTP's. These plants are not only affordable but also provide final effluent to comply with the strict standards set out by the Department of Water and Forestry (DWAF).These plants are easy to operate and do not need permanent staff on site.

There are no moving parts in the plant and the whole plant is built underground. In the majority of the cases grass is planted on top of the plant and only five manhole covers are visible. These plants are also very safe for people, especially children, and animals because there are no open dams. There are also no foul odours and unsightly its.
