Technology to turn brackish water into drinking water is being installed in the Memba district of Nampula province in northern Mozambique.
The unique technology is being installed in the coastal district of Memba in the eastern part of Nampula province which has a water crisis, while at the same time the viability of the technology for national rollout will be assessed and evaluated.
Desalination is accomplished by means of reverse osmosis, a high-pressure filtration technique that reduces salinity and produces potable drinking water.
The newspaper Diário de Moçambique explains that the process starts with the installation of equipment, then a collection and treatment station and finally distribution, all using state-of-the-art technology already in place and being tested.
This government initiative found in neighbouring South Africa what is now seen as the most viable solution for Nampula, which has abundant but salty aquifers. Sometimes, for the same reason, rocks appear in areas where there is no brackish water, again jeopardising efforts to supply water.
Reverse osmosis treatment has proven successful in South Africa and Timor Leste, among other countries.
Nampula governor Victor Borges visited the installation on Tuesday. The equipment fits into a single container but will have enormous impact on peoples’ lives.
Governor Borges received an explanation of the operation of the system and learned that at this stage, it will transform the water collected from subterranean aquifers and deliver it to Memba taps without a trace of salt, to the relief of the local population.
In the event of the aquifers being exhausted, a pipeline currently under construction will pump sea water to the equipment, which it will process in the same way.
“You are to be congratulated for leading a process that puts us in a privileged place as pioneers of this technology. We are looking at a high-performance technology that will serve the rural population and be proof of the government’s commitment to responding to the population’s problems,” Governor Borges said.
Because Nampula faced challenges providing drinking water, all kinds of technologies must be considered as possible solutions.
The governor instanced the river Lúrio, which has plenty of water but of high salinity. The river rises in the Namuli mountains in Zambézia and passes through Niassa, Nampula and Cabo Delgado before entering the sea at Lúrio in Memba and Mecufi in Nampula and Cabo Delgado provinces respectively.
