DESEA Peru provides comprehensive community health solutions to rural communities near the Sacred Valley, Cusco, Peru. DESEA has a three-pronged approach which includes:

This integrated approach is significantly reducing mortality and morbidity rates in project areas, particularly for mothers and young children.
Clean Water

kids with pvcf ilterDESEA constructs biosand water filters in its Lamay workshop, which are installed in homes and schools with the assistance of community residents. We educate residents in the importance of clean drinking water and safe hygiene and sanitation practices and in the use and maintenance of their biosand water filter. Through on-going filter monitoring and education carried out by DESEA’s community health workers (qhalis) and nurses DESEA achieves a correct filter usage rate greater than 90%, measured one year after installation.

The CAWST Biosand Filter

carrying filterConcrete biosand water filters, designed in the 1990’s by Dr. David Manz of the University of Calgary, have been refined and promoted since 2001 by the Centre for Affordable Water and Sanitation Technology Through its comprehensive extension and training programs, CAWST has fostered adoption of this technology at locations throughout Africa, Asia, and the Latin American-Caribbean region.
In 2008 and 2009 DESEA constructed and installed 150 of the CAWST–design concrete filters, but found them too heavy to move to the less accessible homes, those which were most in need of improved drinking water.

DESEA’s Biosand Filter

Matt Dayka-Vitamin Angels PE12-1949In 2011, DESEA director Sandy Hart, with assistance from volunteers Matt Hastie and Pat Teti, designed a biosand water filter using 315 mm (12”) PVC pipe, which adheres to the geometry and efficacy of CAWST’s widely-tested concrete filter, but weighs only 10 kg. The PVC model has been tested in-house by DESEA, by NGO Soluciones Prácticas (Sicuani, Peru), and by the Peruvian Ministry of Health. These filters have now been installed in over 250 households and schools in DESEA’s project communities, many of which would have been too inaccessible for concrete filter installations.

How does a biosand filter work?

7The biosand water filter involves slow percolation of water within a 90-cm, free-standing concrete or plastic container of fine sand (with a biologically-active layer at the sand surface) and lower, drainage layers of gravel. Based on in-house and independent studies, CAWST reports that biosand filters are able to remove 95-99% of bacteria; 90% of viruses; and 99.99% of parasites (including Giardia, Cryptosporidium, other protozoa, and helminths). DESEA’s PVC filter provides up to 15 litres/hour of treated drinking water.

Filter Installations and Training

mary luzDESEA constructs the PVC filters in its Lamay workshop and transports them to the communities. Filter recipients then assist with transporting the materials to their homes, washing of the sand and gravel media, and installation of their filter. Residents also participate in a mandatory training course relating to water filter maintenance and safe hygiene and sanitation practices. Monitoring of the filters is carried out initially by the DESEA nurses in the company of qhalis, and later, by the qhalis independently. Continuous family and community contact is a vital element of DESEA’s approach. Fully acquainting community residents with the link of drinking water quality to human health and with the importance of safe hygiene and sanitation can be a very gradual process. Through the long term, DESEA’s qhalis will provide this on-going support, while maintaining contact with DESEA staff and other government and non-government medical services.

Health Conditions in the Project Areas

Chaipa valleyIndigenous (or campesino) people of the Andes have some of the poorest health outcomes in Latin America. Overall, Peru has the second highest maternal and infant mortality rates in South America, and the remote Andean communities have rates significantly higher than the national average. In DESEA’s project areas, living standards are very low, particularly at the higher elevations where the climate is harshest and agricultural production is poorest. Families typically live in crowded adobe buildings with rustic furnishings, poor smoke ventilation, no access to potable water, no telephone service, frequent access to homes by domestic animals, and, in many cases, no functional latrines. Drinking water sources at streams, springs, or shallow wells are frequently contaminated by fecal coliform bacteria, parasites, and other pathogens.These adverse living conditions, together with limited access to health care services, have produced very high rates of illness and mortality, especially for under-five children, mothers, and the elderly. To address these issues DESEA Peru has implemented a comprehensive water treatment and community health program in the project communities.

Health Services

DSCF7670DESEA Peru nurses provide a comprehensive, community-based health program strongly rooted in health promotion and illness prevention that is significantly improving health outcomes. In project communities, since the initiation of DESEA’s healthcare model, there have been no maternal or under-five child deaths from preventable illnesses. As well, there has been a significant decrease in diarrheal disease and pneumonia and a significant improvement in nutrition in children and pregnant and lactating women.

DESEA nurses provide bi-weekly clinics in each community, seeing patients, wherever they are encountered, thereby providing a realistic and respectful approach to community members who live long distances from the nearest Ministry of Health clinics. With the direct involvement of qhalis (community health workers), DESEA Peru nursing staff provide on-going instruction to families, schools, and community groups in water filter use, hygiene and sanitation, nutrition, and healthcare practices. DESEA nurses and qhalis also work in conjunction with the Ministry of Health medical health clinics and assist with Ministry of Health programs such as their monthly health days and dental campaigns.

Qhali Program

DSC_0130The term qhali is derived from the Quechua expression qhali’kaypac llank’sun meaning working for health. Qhalis are women who are elected by their community, in collaboration with DESEA, to train and practice as community health workers. A primary goal of this program is to train the qhalis to provide sustainable family health education and support. The qhalis serve as the sole health providers who are permanently and immediately available to their communities.

DESEA has developed an innovative program for the training and activities of qhalis which does not require literacy or numeracy, challenges which face most local women. During their first year the qhalis receive more than 200 hrs of healthcare training, using theater, hands-on practice, art, and interactive learning, all presented in their maternal tongue of Quechua. In following years they participate in continued workshops together with newly-selected qhalis and they provide family education both by themselves and in the course of community visits with DESEA nurses.

Qhali Training

DSC_0742Qhalis are trained in a wide range of health issues affecting their communities, including: advanced first aid; reproductive health; prenatal health; postnatal/neonatal health; care for sick children; chronic health conditions; care for the elderly; traditional medicine; occidental medicine; water filter installation, monitoring and maintenance; hygiene and sanitation; nutrition; mother and child stimulation; tuberculosis; alcoholism; domestic violence; and leadership and social change.

At the end of the first year of training each qhali will be able to:

Community Health Programs

When community members are empowered through respectful and effective educational programs, positive health changes can be realized. DESEA community health programs are managed by the DESEA nurses and qhalis (community health workers) and include:

Support DESEA: directly improve the quality of life in high Andean communities.

In indigenous communities, families and schools receiving water filters volunteer their labour in filter construction and installation, but they have no funds for filter costs. Direct program expenses are sustained entirely by donations.
