rainwater harvesting:
with the potential risks of using contaminated water, rainwater harvesting seems to be one of the most viable and safe options for water collection. the UCF student handbook shows the amount of water that falls in falmouth on average per month. Water aid also recommend rainwater harvesting as one of the best ways of getting clean drinkable water. there are also several sources of harvesting methods, although most are centred on integrated housing solutions.
Water security:
water security is essentially the issue of water access. A lot of places have limited access to fresh water, and a lot of it is imported. water security relates to our continued access to clean water, or our potential lack of it. Finding ways of getting clean drinkable water is a bigger issue than just a small localised one. it has the potential to affect most of the western world and it has been said that the next world war will be fought over water.

reverse osmosis:
the way that water pumps work is by forcing water thorough a semipermeable membrane that only water particles are small enough to fit through. This is particularly useful as it filters salty water to provide fresh water.
