Discussion• All the systems work in different ways. Decide which systems are most suitablefor villages.• Which kind of system do most people want?• Which system would you prefer and why?• Think about your home village. Discuss which system would be most likely tofulfil the needs of the villagers and be the easiest to maintain.• Both write a paragraph, explaining which system you want for your village andgiving reasons for your choice.MaintenanceMaintenance of the water source and supply system is important to ensure a continuoussupply of good clean water. Maintenance is generally quite simple and is usuallyundertaken to prevent problems occurring. For different situations it may include:• Protecting the water source (e.g. rivers or ground water) by ensuring it does notbecome contaminated from people or animals. Soap, chemicals, oil, rubbish,dead animals and human and animal faeces can all pollute water to make itunsafe for people to drink.• Water sources such as rivers or lakes can also become clogged by earth andplants either naturally or from poor gardening and land management practices,reducing the amount of water available. A water source must always be keptclear.• With a rain water catchment the following must be checked regularly:- Check the roof of the catchment building is clean and free from rubbish, dirtleaves etc..- Clean the guttering where the water runs off the roof to make sure it is alsoclean and not full of leaves and other debris.- Check there are no leaks in the pipes or tap.- Ensure the area around the tap is clean and water does not collect andstagnate there. If it does, dig a drain so that water can drain away from the tapsite.• With a direct gravity feed system the following must be checked regularly:- Pipes must be kept unblocked at all times.- The intake pipe at the source particularly must be kept clear of all debris so thatwater can enter the pipe easily.- All leaks in the pipes or damaged pipes must be fixed to ensure a steady flow ofwater with no loss of water pressure and water loss.- Ensure the area around the tap is clean and water does not collect andstagnate there. If it does, dig a drain so that water can drain away from the tapsite.• With a handpump, there is fortunately less maintenance. However, the soakaway must at all times be kept clear of stagnant water. It must therefore be builtso that water can drain away easily. As a handpump brings water up from theground from directly underneath the pump it is important to make sure the pumpis located where the water cannot be polluted either by pigs, waste water,sanitation etc. as anything poured onto the ground can soak into the groundwater making it unsafe for humans.36 Wora Hemi Laef - A Work Book
