DEDICATION
This website and everything that TASCA has accomplished and will accomplish is dedicated to and due to Dr. Robert Harvey, PhD. An experienced microbiologist, Fulbright scholar, husband, father, grandfather, and humble humanitarian. He was the founder and heart and soul of TASCA until his untimely passing in 2016 at the age of eighty.
During his first visit to Nicaragua in 1988 Dr. Roberto as he was known in Nicaragua, recognized that children as well as adults were being sickened and dying from drinking contaminated water. He knew he could be a force for improving health in rural communities with his skills, knowledge, and resources. From his first visit until his death he dedicated his life to improving water quality and quality of life for rural Nicaraguans. Every year from 1988 he went to Nicaragua to personally deliver supplies and equipment to laboratories and to support the lab technicians through teaching upgraded techniques.

Dr. Roberto thoroughly enjoyed his time roaming the mountains of remote rural areas, testing water for quality and talking to the local people in his excellent Spanish. Dr. Bob will always be remembered by the many friends he still has in Nicaragua for his selfless dedication to helping those in need.

Organizational History
TASCA (Taller de Agua y Salud Campesina-Workshop for Water and Rural Health) was formed by Joseph Ryan, Frederick Jacob and Dr. Robert Harvey in 1991. The purpose of forming TASCA was to continue supporting Nicaraguan rural water projects that the three had started in 1989 while working in the Cuá-Bocay valley with Veterans for Peace and Veterans Peace Action Teams.

The need for this work was epitomized in a single statistic from WHO (World Health Organization): infant mortality, death before 5 years old, was 68 per 1000 live births in Nicaragua in 1991 when TASCA began, compared to 3 – 8/1000 in more developed countries. About 25% of this infant mortality was caused by water-borne diseases. Providing clean drinking water as part of a general improvement in sanitation practices is proven to have a major impact on improving infant morbidity and mortality by 25%.

To this end the primary focus of TASCA has been to provide and support water testing and water chlorination necessary to ensure that new and existing water systems provide uncontaminated potable water. TASCA does not construct water systems; this is done by other organizations. TASCA has applied its expertise in microbiology, laboratory management and public health to develop and support the infrastructure necessary for the maintenance of these water systems.

WHY CHLORINATOR INSTALLATIONS ONLY IN NICARAGUA
During the development of The Manual Chlorinator it was always our intention and desire to spread the technology of the Chlorinator freely. Clean water could be available to many countries with a simple proven technology to decontaminate drinking water. After field trials proved that the chlorinator worked as designed, we initiated projects in both Honduras and Guatemala as the beginning of our international efforts. However analysis of projects in both countries concluded our efforts were unsuccessful.
The reasons for the lack of success of those projects indicated that functioning community Water and Sanitation Committees (CAPS) were essential for a successful and sustainable water project. Additionally support from both Health and Water Ministries is critical for any health initiative to succeed. Neither Honduras nor Guatemala have a support system for the CAPS or involved governmental Ministries, while Nicaragua has a strong national CAPS for supporting the local rural Water Committees and involved Health and Water Ministries.
One of the advantages of Nicaraguan water projects is that when rural water systems were built, many by UNICEF, the communities were required to have Water and Sanitation Committees (CAPS). These Committee members maintain the water systems and each household agrees to a small monthly fee to maintain and support a fund for water system repair by the CAPS. This fee also covers the cost of the chlorine tablets used in The Manual Chlorinator.

Our approach has been to engage in long-term collaboration with governmental organizations, such as the Nicaraguan Ministry of Health (MINSA) and the Nicaraguan Water Ministry (ENACAL/DAR.) Within these organizations we collaborate with lab technicians and health care providers who are intelligent, dedicated, and enthusiastic. TASCA established a scholarship program to improve the qualifications of public health workers, and also provided laboratory equipment to maintain and strengthen the laboratory infrastructure as far as possible. We have lent our expertise and experience to provide technical consultation and training on a continuing basis.
MANUAL CHLORINATOR DEVELOPMENT
Compatible Technologies International (CTI), a Minnesota NGO, was the funding organization that supported the creation of the Manual Chlorinator in 2001 in association with TASCA. CTI has since changed its name and mission and TASCA is now the sole proprietor and promoter of the chlorinator.
In 2001, having received funding from the Lilly Family Foundation, CTI initiated a pilot chlorinator project in Nicaragua, Central America in the rural community Chilamate. Nicaraguan Water Ministry technicians and Chilamate community members of the local Water and Sanitation Committee were trained in chlorinator construction and operation.

A yearlong pilot project in the rural community of Chilamate, Matagalpa proved the chlorinator was an effective tool in delivering clean water in rural water systems. In 2002 twenty-one chlorinators were installed in gravity fed water systems in northern Matagalpa and Jinotega Departments. The results of statistical data from the twenty-one systems proved the chlorinator functioned as designed. All systems delivered a constant flow of uncontaminated drinking water, delivering doses of chlorine within the standards set by international and national water and health agencies. Ministry of Health data from communities with chlorinated water show less incidents of intestinal disease.
