As a result, fertility starts to drop at an annual income per person of $1,000-2,000 and falls until it hits the replacement level at an income per head of $4,000-10,000 a year. This roughly tracks the passage from poverty to middle-income status and from an agrarian society to a modern one. Thereafter fertility continues at or below replacement until, for some, it turns up again.
The amazing thing is that this is true across all societies, and even for poor regions in otherwise above-subsistence countries.
Consider, then, the potential impact of taking back the 15 to 17 hours per week that poor women and girls spend collecting water. It would substantially boost the productivity of over half of the entire population.
Handpump Reliability a Major Part of the Problem
In his recent essay, Edward D. Breslin, CEO, Water for People, says it best, “But the images that dominate - pictures of children happily gulping water from a new tap - do not tell the whole story. The real image should be the one that plays itself out every day all over the world -- of the woman walking slowly past a broken handpump, bucket at her side or on her head, on her way to (or from) that scoop hole or dirty puddle that she once hoped would never again be part of her life... The broken handpump is a constant reminder of our inability to escape poverty."
SImple Pump Can Help
As will be explained in more detail, by any measure, the hand pumps deployed in the developing world are quite unreliable. All the data we have show that Simple Pumps are many times more reliable.
The initial purchase price of the currently-used pumps is significantly less than a Simple Pump. Therefore, many find it surprising that, compared to the pumps currently deployed in developing nations, Simple Pumps are several times less expensive to buy, install and operate, if total costs over the useful life of both pumps is considered.
Many factors will determine whether much of the world’s destitute will be able to escape subsistence-level poverty. However, it is inescapable that such an achievement will depend upon dramatically improving the reliability of handpumps, and therefore the availability of clean water. We expect that, when you know the facts, the Simple Pump will be the obvious choice.
