Basic water quality testing is recommended during the first year, with further testing when water quality is in doubt. A low cost water test is the ‘HACH’ test, about US$1 per test. If contamination is suspected or when water quality needs to be guaranteed, the water can be treated in several ways.

====ManufactureShared roofs====It Operation and maintenance (O&M) of shared roofs have more challenges. Rooftop-harvesting systems at schools, for instance, may lose water from taps left dripping. Padlocks are often needed to ensure careful control over the water supply. Ideally, one person should be responsible for overseeing the regular cleaning and occasional repair of the system, control of water use, etc. One option is advisable to first construct sell the water, which ensures income for O&M and for organizing water use. Where households have installed a small communal system (e.g. where several roofs are connected to one tank before attempting ), the users may want to establish a large onewater committee to manage O&M activities.A concrete lid protects The activities may include collecting fees, and controlling the caretaker’s work and the tank from pollutionwater used by each family. Small fishes External agents can be kept play a role in the tank following O&M areas:— monitoring the condition of the system and the water quality; — providing access to credit facilities for buying or replacing a system; — training users/caretakers for management and O&M; — training local craftsmen to keep it free from insectscarry out larger repairs.
