Finances Operational and investment costs WaterPyramid Since the workforce for the WaterPyramid is locally recruited and direct costs related to energy are low, the operational costs are low (about 1/10 of those related to reverse osmosis installations). The investments costs of the WaterPyramid are comparable to the cost to purchase a state of the art reverse osmosis system in combination with appropriate power supplies and other necessities. In order to make the WaterPyramid financially sustainable, usually a mix of grants, (soft) loans, and micro-financing tools are combined to make the purchase possible. Private (local) banks, NGO’s and Communities play a vital role in the financing of the package. WaterPyramid Micro-finances We favor the vision that all parties involved in the exploitation of the WaterPyramid should bare some sort of financial responsibility. This vision is being translated into a micro-financial scheme which can be applied e.g. within communities to collect funds to finance operations and maintenance. Together with our partners we are experienced in this field and are willing to use our knowledge for the best possible micro-financial solution.
