Abstract
The system comprises one or more of the following: primary treatment units, flexible pipes, and optionally, one or more pumps. The system is designed and installed in a manner that enables the flow of liquid to be predominantly due to gravity, although one or more pumps may optionally be included at key positions. The system can be sealed and pressure tested in order for optimal performance to be achieved during operation.
