Builders RemindersDesign and construct foundations using qualitymaterials and ensure that steel bars extendbeyond the foundation walls to aid propersecuring of the wooden structure.Foundations of buildings located in floodplainsmust be designed to withstand dynamic waterforce and battering action from floating debris,and the effects of erosion due to scouring.Figure 5.9 Wall Connection to Foundation59
Cisterns -Cisterns are storage tanks for rainfallthat has been collected from a roof orsome other catchment area. Althoughusually located underground, cisternsmay be placed at ground level or onelevated stands either outdoors orwithin buildings. Cisterns should be watertight, have smooth interiorsurfaces, enclosed lids, and be large enough to provide adequatestorage. They should be fabricated from non-reactive materials such asreinforced concrete, galvanized steel, and plastic.CATCHMENT SYSTEMA catchment is an area from which runoff is collected. Galvanizedsteel and aluminum roofs are the best commonly used catchments.Rough surfaced materials collect dirt and debris that affect thequality of the water collected. Gutters and downspouts should beeasy to clean and inspect. Rainwater picks up dust, soot, birddroppings, leaves and other foreign materials that add objectionableorganisms, color and odor to the water. Gutter guards and roofwashers can improve the quality of the collected water. Gutterguards made of 1/4" to 1/2" mesh hardware cloth placed over thegutters keep out leaves and other large objects. Sand, gravel orcharcoal filters are sometimes used to filter water before it entersthe cistern but they require frequent maintenance to preventcontamination.Roof washers are cheaper to construct and need less maintenancethan filters. A roof washer traps the first flow from the roof andchannels this dirty water away from the cistern. After the first flow,the water from the rest of the rainfall flows to the cistern. The roofwasher should have a capacity of about 10 gallons for each 1000square feet of roof area.CISTERN SIZE AND CATCHMENT AREAThe cistern size must be adequate to supply water needs duringextended periods of low rainfall. A margin of about one-third shouldbe allowed for water leaked from pipes, blown from the roof bywind, lost to evaporation and channeled away by the roof washer.The required catchment area depends on the amount of waterneeded, the cistern size, and the frequency of rainfall. The cisternand catchment area must be sized together. The catchment areamust be large enough to collect enough water from rainfalls whenthey do occur.60
