Do you ever wonder why municipal water supply is fast disappearing in most African Cities and Semi-Urban centers? Have thought about why many City Water Works (or Government owned Water Boards) are no longer in business?
If you live in the Western World - this may be hard for you to believe - that there is such a thing called "None Revenue Water (NRW)" - meaning people get water delivered closed to their door steps, pipe-born for free. They just collect water or use public water for free.
Little wonder then many of the public water establishments are broke and folding up or already out of business. In a place where 40% to 50% of the treated or pumped underground water that goes into high overhead reservoirs and piped to users under gravity pressure end up leaking away for lack of maintenance, and lack of repairs attributed to lack of funding - how do you sustain steady supply when the population has continue to grow at over 4% each year?
A city like Lagos and Lusaka has bad ground water supply with nitrate / nitrate concentrations well above WHO recommendations (about 50 mg/l), plus other pollutants that includes sewage and fecal matter in water. These cause undue health hazards to the populations, in particular during rainy season when the underground water table rises. The rise in the incidents of water borne diseases as reported by many hospitals and clinics correlate well and confirm these observations.
WATER QUALITY ENFORCEMENT WITH WATER METERING
It makes sense to meter and sell water today in Africa because of the obliquity of mobile phones and growing Internet accessibility even in rural Africa.
While living in Nigeria during the mid-1980s to early 1990s - mobile phones were just begin to surface. My application with the phone company for a land line took almost 6 years to get approved. Today in Nigeria people pay N20 per 25 liters of water on the average - that's about 8 to 10 cents. By contrast that's about 50% of what they pay to get the lowest unit of mobile phone recharge card at N50 for about 16 to 18 cents - to make a call and talk for about 10 to 25 minutes.
Let's fast-forward to our new era and different scenario today - where people are capable of paying for the water they use, albeit, some small amount to cover the cost of water treatment, supply and last mile delivery to users. At RNM, we propose a new innovative solution that does the following:
Identify good water sources with high yield volumes - especially deep wells in good aquifers
Ensure that water quality testing is done on such wells (public or private) by private sector contractor working in collaboration with the Government / Local Authorities for permits, and quality control audit enforcement.
RNM in collaboration with water meter manufacturers installs PAGO (Pay As GO) water meters that use rechargeable plastic smart cards with stored value and quantity of water that user desires to purchase in them.
RNM also works with private sector to install and maintain the necessary last mile pipelines and public meters within each segment of the City / semi-Urban areas to cover areas with high population densities - typically areas with more than 20,000 persons per square Km.
Revenue generated from water recharge card sales used on the meters are directly deposited into back accounts (60% go to Well Owners, 25% to RNM, 5% Government, and 10% to Water Quality Testing partner for twice a year water quality audits). There is no cash transactions done at point of water delivery and card use for best accountability and to avoid corruption that has plagued Africa.
SUSTAINABLE WATER - METERED WATER
The above setup will allow RNM to adopt wells that it did not drill for example into a grand scheme public water supply system; treat the wells that need to be treated and pump the water down to water points at dense locations where needed most under the control of public our meters. Private homes that wants independent meters will be equipped with one with water piped to their gate or doorsteps at service entrance. Such owners will also purchase their own PAY-GO cards for the amount of water needed over a certain duration based on quantity use pattern for the household - daily rations, or per week, or month.
For large consumers such as an Industry or big Commercial user like a restaurant, or hotel - RNM can install smart meters with prepaid support features that include GPRS / 3G / 4G mobile network technology. About 3500 of such smart meters can be managed by remote GPRS / 4G controllers working together with Cloud-based computers to provide water access, user control as well as give users access to their usage reports in real-time. This will be the 2nd phase of our program design towards sustainable water use in Africa.
