A friend of mine, Thomaz, said so many good things about Richards Bay and its Mhlathuze Water...
A state-owned water utility, was established in 1980 to design and construct a major regional water treatment plant and an offshore wastewater disposal system to service the growing town of Richards Bay in the province of KwaZulu-Natal. As a service provider and partly as part of its mandate, the organisation has increased its service delivery to local and regional municipalities, assisting the water service authorities to provide potable water to urban and rural communities. The organizations area of supply now covers 37 000 square kilometres in northern KwaZulu-Natal with assets in the region of R 3.1 billion.
Treat and serve water and collects and treat effluent, including the gypsum of Foskor.
Thomaz compared with Morocco OCP´s...
And we talk about eventually accepting a system like that in areas like northern Mozambique.
And I though it is quite acceptable!
But phosphogypsum should taken as a building material... once there there are almost no "normal" houses.
Resinated it could do great walls, if there are no radonium emanation.
