What does Africa need more – easy access to fresh water or better cheaper internet connections?

Rory Cellan-Jones, who blogs on technology for the BBC, travels to Mombassa, Kenya to see how a local NGO is using broadband Internet to bring water pumps to farmers. Here are excerpts from his blog entry of 15 September 2009.

“My guide was Martin Rogena, a Kenyan working for an organisation called KickStart, which supplies irrigation pumps to farmers across East Africa. Martin is also a big believer in the power of the internet to transform countries like Kenya”.

“We set off [to] a poor suburb of Mombasa [where every shop] seemed to be selling mobile phones or offering to recharge them – and every few yards there was a stand selling fresh water at around 20p a litre”.

“Martin explained that Kickstart was a charity but it didn’t give away the “Moneymaker” pumps it supplies [but was charging] around £50 for a portable pump – far short of the cost of making and supplying them – and they are now in use right across drought-stricken areas of Kenya, Tanzania and Uganda”.

“[At a] little settlement [...] about 10 miles from the beach where the Seacom cable bringing broadband to the region comes ashore, [Cellan-Jones met a group of] farmers who [...] had clubbed together to buy a pump. [The farmers supported around 20 people by growing tomatoes,] maize and some other vegetables”.

“These people had very little [and there was no electricity] but nearly all of them had mobile phones. [...] The farmers explained that the phones [...] had made them feel much more connected to the rest of Kenya”.

“Outside one of the huts, Martin Rogena got out his laptop, plugged in a broadband dongle [broadband wireless USB adaptor], and went online at a reasonable speed – he was picking up the signal from the nearby mast, which is in turn linked to the fibre-optic cable at the coast. But why, I asked, did a faster internet connection matter to a charity which was trying to alleviate the impact of drought?”.

“He explained that Kickstart collects data from every pump it supplies across the region, sending staff armed with laptops to talk to the farmers and make sure they are getting the right results. From its Nairobi office, It also needs to communicate with donors around the world and with its branch office in Tanzania”.

“The charity is already finding that faster broadband is making communication easier – and is cutting costs, though perhaps not to quite the extent that has been promised”.

“The farmers had never been on the internet – but they too were excited about what it might mean for them. “It will help us find information to help us improve the way we farm.” said one. “We will use it for marketing our crops to other countries outside Kenya,” said another”.

“We headed back into Mombasa, past lines of women carrying water containers on their heads. This country is short of lots of things – water, electricity, books for schools. But there is a great thirst for better connectivity – and who are we to say that they’ve got their priorities wrong?”.

Greywater reuse: water treatment kit for household grey water

A kit designed to treat household waste water for reuse could be one of the ways to tackle water scarcity in rural areas of the Middle East and North Africa, according to a Canadian organisation.

“This is a household-based technology mainly for rural areas to treat grey water that comes from the kitchen sink and bath for re-use,” said Hammou Laamrani, project coordinator at the Regional Water Demand Initiative [WaDImena] of the International Development Research Centre (IDRC), based in Canada.

[...] The kit consists of two large PVC barrels about 1.2m high, each able to contain up to 200 litres of water, pipes and sand. Before reaching the barrels, the waste water goes through a separate filter where things like small bits of food are removed. The barrels are filled with sand; there is an anaerobic digestion of the organic matter when the water goes through the sand filter and becomes cleaner.

“The quality of the treated water is improved chemically and biologically; it [the filter] removes the pathogens, particularly the E. coli that could pose a health risk. It also removes parasite eggs as they cannot go through the filter because the filter is a kind of a bio-membrane that removes all those things,” Laamrani explained.

[...] It has a socio-economic impact, it has a positive impact on the environment and it’s viable in terms of technology used,” Laamrani said.

Waste water treated by sand filter has very little nitrogen and potassium, and in terms of chemical pollution poses no risk for the soil, according to Laamrani. It is not a risk to soil because it does not have mineral components that can increase soil salinity and degradation, and it is not a risk to human beings in terms of exposure to pathogens, he said.

“It reduces the amount of water that goes into cesspits – sanitation in rural areas. So they don’t need to clean the cesspit so often – only once every three months, instead of once a week. This reduces the cost of emptying the cesspits,” he said.

“This water can also be used for productive purposes. It is used for the irrigation of saplings, particularly olive trees like we saw in Jordan… This water can also be reused in the household, like for flushing toilets,” he said.

However, it is not suitable for crops or vegetables consumed without cooking, like cucumbers and tomatoes, he said.

“The cost of the kit is $300-400, and in some cases even less depending on the price of components in any given market. If you take into account the productive use of the treated waste water and the reduced frequency of cesspit evacuation, outlay costs can be recouped in a year in places like Jordan and Lebanon,” the IDRC official said, adding that they also had projects in the occupied Palestinian territories and Yemen.

Maintenance is simple: sand in the barrels needs to be changed every 10-15 years, Laamrani said.

One of the drawbacks with the system initially was the smell: “There was no technology to remove the smell when the water was in the barrels. But it has been overcome with a new system that takes the gas out of the barrels… No longer is there a risk of attracting ants or other insects,” he said
