OBJECTIVE: improve quality of life for thousands of people (mostly children) living alongside the Lima, Lurigancho/Chosica ‘Rimac” river, where 5,000 Bio Sand water Filters are urgently needed (5,000x15 per filter = 75,000 total).

Contributions accepted Club to Club, or minimum Matching Grant of $11,700 which will cover 117 filters ($100 each: 50 filter, plus 50 installation & training)

CLEAN WATER FOR PERU

PROJECT PROCESS Bio Sand Filter: Training by CAWST, Diana Frost, Andrea Roach & Paul

Earwaker Community Selection: Communities were involved in the decision to use

BSF Training: Manufacture, installation and teach communities hygienic norms &

BSF Technical support & Project Execution: Contracted to EDES and CAWST Financial Assistance (first project MG 66806): The Rotary Foundation, RC

Holmen, RC LMV and RC Gibson, Canada: projector and part of CAWST initial training

Workshops and Seminars: Started in 2007, will continue throughout the duration of the project until the communities become self sufficient (build, use and maintain filters).

• Water contamination historically has been related to the discharge of mining waste in the upper and middle part of the basin and pollution discharge along the stream.

• Rapid growth of population in Lima is leading to an expansion of unplanned informal settlements, which lack basic urban services such as waste management, clean water and drainage, contaminating the river with pathogens

• Contaminated water in many communities along the riverbank, many people manually collect or buy it from trucks to use untreated water for their households.

Delivering and collecting contaminated water brought in trucks from Rimac river

WELLS at ’27 DE JUNIO COMMUNITY’ • Wells were highly contaminated with feacal matter (99% samples)• The study identified the river as the major source of pollution, surface

contamination of uncovered wells were also causes of infections.

’San Pedro and San Pablo’ y ‘VillaEsperanza de Jicamarca’, both inLurigancho Chosica district, Lima

Community Sellection for250 filters MG 66806

Closing the exposed wells to prevent external contamination

• Workshops, focus groups & surveys to promote health awareness & education.

• Weekly diarrhea occurrences analyzed to assess effects of BSF, before & after  

• Water samples collected to detect parasites in children (started march, 2007).

Baseline surveys

1. Educational sessions were held focusing on key hygiene messages to protect infants against diarrhea:

• washing hands before preparing food and after using the toilet, • safely disposing of infant faeces, and • safely storing water in the house to prevent microbial re-

contamination

Results of lab Tests

Wells water quality Before BSF: 756 MNP of CF/100 ml. not good for consumption

After BSF: 11 MNP of CF/100 ml, a bacterial removal of over 98.6%. Additionally, mothers comments about their water after BSF “improved the flavour, no more insects or fine sand , it is cleaner and more crystalline”

Before BSF, lab results showed protozoa re-infection in more than 60%, Giardia lamblia (70%) and Blastocystis hominis (40%) in children which decreased significantly after filters were used. After BSF mothers also noted children diarrhea occurrences were cut in half.
