One of the most quoted WASH statistics was recently “downgraded”. For every $1 invested in water and sanitation, not $8 but “only” $4 is returned in economic returns through increased productivity. This recalculation , says the World Health Organization, is mainly a result of higher investment cost estimates and the more complete inclusion of operation and maintenance (O&M) costs.
Providing a better insight into O&M costs has been one of the achievements of the WASHCost project of the IRC International Water and Sanitation Centre. WASHCost has published minimum benchmarks for costing sustainable basic WASH services in developing countries . The project collected data from Burkina Faso, Ghana, Andhra Pradesh (India) and Mozambique.
The main message is that spending less than the minimum benchmarks will result in a higher risk of reduced service levels or long-term failure. NGOs claiming that “US$20 can provide clean water for one person for 20 years” have clearly forgotten to include annual recurrent costs for operation and maintenance, capital maintenance and direct support.
The real cost for 20 years of basic water supply from a borehole and handpump would be, per person, between US$ 20 and US$ 61 for construction plus US$ 3-6 every year to keep it working. In total for the 20 years this would amount to US$ 80 to US$ 181 per person.
Similarly, for the most basic sanitation service, a traditional pit latrine, the combined costs would be US$ 37 – 106 per person over 20 years.

Nearly half of India’s 1.2 billion people have no toilet at home, but more people own a mobile phone, according to the latest census data.
Only 46.9% of the 246.6 million households have lavatories while 49.8% defecate in the open. The remaining 3.2% use public toilets.
Census of India 2011 - Availability and Type of Latrine Facility: 2001-2011
Census 2011 data on houses, household amenities and assets reveal that 63.2% of homes have a telephone. More than half the population – 53.2% – have a mobile phone.
Under-five child mortality from diarrhoeal diseases, which was 1.7 million in 2005, is expected to fall to just over half a million by 2030 and around 130,000 in 2060, a new study  predicts.
The study notes that headway is being made in fighting communicable diseases such as diarrhoea, malaria and AIDS. At the global level disease burdens are shifting from communicable diseases to chronic ones such as cancer, diabetes and heart disease.
