Roof Rainwater catchment• Ideally should have:

– Good material for gutter (PVC, high grade aluminium)

– Solid clamp to attach gutter to the roof (carefull strong winf…)

– Large tank of 750L (15L/p/d * 50 person in shelter) – Tank has heavy duty tap, and 3 complete spare

tap to replace tap if broken– Tank elevated of 1m (above flood level)– Tank located close to roof– Cloth filter or mesh on top of tank to avoid

impurities from roof going into tank– Tank should have 2” overflow pipe

Bad: container too far from roof

Good: container should be elevated, with a tap

Good container but too far from roof, and gutter material too light

Good container, with cloth filter on top to filter impurities from roof, and overflow pipe

Bad gutter system, will leak and last only 1 month. Better grade aluminum is needed or other material should be used

Very good gutter in Ivory coast (PVC fitting)

Very good gutter using good quality aluminum and fixing system in Ethiopia

Also good plastic gutter in Columbia

Water for the latrine…

Good catchment for a household in Columbia, with overflow pipe
