* '''Note''': Assuming a lifetime of 5 years, 16 hours daily operation, meaning approximately 2.000 litres/day is processed, no membrane replacement is required. The UV lamp should be replaced every 2 years. The cost of one UV lamp is €300 (medium pressure; 9.000 hours). Operation cost is based on 16 hours per day * 3,1 kWh; electricity price in the Netherlands per kWh is €0,08. Hence, estimated annual electricity cost is €1450. Salary is assumed €500/year (fulltime); based on GNI per capita of least developed countries (World Bank).
