Existing standpipes were replaced with Maji Dispensers embedded in cement. Using only local materials, a bed was created in the existing wall with a hammer and chisel. PVC pipework that would directly serve a brass tap was quickly re-routed via the 3/4” Maji Dispenser inlet and outlet, before fixing the cases with masonry nails. Finally, the dispensers were sealed in with cement and the pipework plastered over in what is the local customary method.

Prepaid contactless WaterCards are distributed to households and individuals. The pre-paid card concept was easily understood by users, and required no training. Once topped up by exchanging local cash with a shopkeeper in a procedure that came very naturally, users then instinctively knew to insert their WaterCard into the dispenser to make the water flow.

Using any NFC-enabled Android mobile phone, selling WaterCard credit to users is a fantastic way for shopkeepers, mothers, or people with health impairments to make an income. The WaterCard micro-economy gives people in the community a stake in their water system and an incentive to take care of it.

The existing village water committee, along with an NGO representative, are able to collectively and transparently manage the loaning of WaterCard credit to resellers. They are able to monitor each sale and download daily and weekly account statements for all transactions at the dispensers. Collection of physical cash is now guaranteed and provides sustainable funding for the borehole pump and water system. 100% of water sales are now fully accountable - revenue loss, theft, favours and embezzlement is now an impossibility.
