Based on WHO drinking water quality standards and field studies
conducted in Burkina Faso, Ethiopia, and Nepal, the Rain Water
Harvesting Implementation Network (RAIN) has established the
following standards: To achieve these standards, RAIN has
recommended the following techniques: 1. Sampling and
collection: Undertake sampling between rainfalls; agricultural
pesticides and pathogens such as E-Coli are more concentrated
immediately after runoffs from rainfall. Clear debris and silt
from storage tanks and runoff pipes. Handle collected water in a
hygienic manner. 2. Analytical process Try to perform testing
directly on-site. Harvesting systems are distant from large
cities and require long transportation times which can alter
results. The testing process should be conducted by a trained
professional, capable of collecting accurate storage samples in
the field. To improve drinking water quality, the following
techniques may be used: Chlorination: treating collected water
with chlorine effectively removes and d
