I. EXECUTIVE SUMMARY Every day, the residents of the Mathare Valley slum in Nairobi, Kenya are exposed to the risk of death and disease from drinking contaminated water. They have to rely upon leaky, illegal connections to the city’s water supply system, which are prone to contamination with raw sewage from nearby open sewers. The average Mathare household cannot afford to pay for ‘legal’, metered connections to the city system, and in any case, the supply is frequently cut off due to Nairobi’s ongoing water rationing regime. Outbreaks of cholera and typhoid are commonplace during the rainy season, when storm water containing concentrated sewage submerges and infiltrates the water supply pipes. Consequently, women such as the one pictured on the front cover are forced to walk long distances carrying buckets and cans in search of clean water elsewhere. (Name of Applicant Organisation) would like to install a ‘PROtector’ water treatment system on the bank of the polluted Nairobi River, which flows through the middle of the slum, enabling as many as 3000 residents to extract water directly from the river and purify it to a safe and potable standard. The PROtector water treatment system is operated entirely manually, by means of pushing a rotational handle, and it is capable of removing silt, cysts, bacteria, viruses, chemicals and heavy metals from water. There is no need for electricity or fuel in its operation, and it can produce fresh, safe drinking water at a rate of 1,000 litres per hour. The PROtector is simple and robust enough to be operated and owned entirely by the community. The proposed Mathare PROtector installation will provide the following key benefits: Water purified directly from Nairobi River Green Tech - No power source required Treated water 100% safe & compliant with Community health and productivity greatly World Health Organization guidelines improved, saving 2% GDP per capita, per annum Enough water for 3,000 people per day Ownership & operation by community Low Cost - USD $0.02 per 20 litres (5.28 Opportunity for microenterprise (water kiosk) gal) The projected net benefit to the beneficiary community (based upon improved health and productivity) is estimated to be USD $200,000.00 over a period of five years. This equates to a return of USD $5.00 for every $1 invested in the project.
