In most rural areas. community sanitary surveys are usually necessary to obtain first-hand information concerning local sanitary conditions and needs. Such surveys, undertaken with the participation of local leaders of the community, will be of immense help in program planning and evaluation. Such a survey should cover the following factors.
DESCRIPTION OF AREA
1. location, topography, climate, character, communications, maps;
2. geology and hydrology, with particular reference to nature of top and underground layers of the soil, its porosity, presence and abundance of ground water ( if any), direction of flow, level of ground-water table, its appearance and portability, estimation of yields of springs, rivers, and so on;
3. population - number, constitution by age-groups and sex, density, growth;
4. industries and agriculture, with particular reference to irrigation, drainage, and soil fertilizing practices;
MEDICAL AND SANITARY DATA
1. general health of the population, with special emphasis on communicate diseases and on intestinal infections;
2. vital statistics, mortality and morbidity data;
3. health and sanitary administration, with reference to organization, personnel, budget, and activities of voluntary or other agencies in the field of sanitation;
4. existing sanitary conditions in the area, with reference to description of private and public latrines, their distribution and use; to wells, springs, and other systems of water supply (including such information as number of persons served by piped water-supplies, and by wells, the consumption and uses of water, number of dwellings with private water supply, etc.); to wastes collection, disposal, and composting; to milk and food sanitation; to insects (flies, fleas, lice, mosquitoes); to health aspects and standards of housing; and to school sanitation.

3. housing and vehicle transport for program, vehicle and equipment repair and maintenance facilities; sources or power (electricity, fuel);
4. local construction materials and their costs;
5. local craftsmen and wages;
6. potential resources for self-help;

In short, it helps to prepare a "social map" of the community.
