Hello, Lebanon. It’s me, your friendly Green Patriot. The amount of rain we’ve been getting over the past few weeks has been interesting, to say the least. Lately, we’ve been getting a lot of rain, but I don’t think we will have that luxury for long. We are due for a serious water shortage by 2015.  

The amount of rain we’re getting…and the short arc of time during which we will have it…makes me think about rain harvesting all the more. For those unfamiliar with the term, rain harvesting is a method through which we can accumulate, treat, store, and later reuse rainwater. People do this to have more drinking water, water for livestock, water for irrigation, as well for menial things such as cleaning, etc. It can even supplement groundwater, and make a large difference in the amount of usable water available to us.

This is done in a very easy and inexpensive fashion. Rainwater is collected from the roofs of buildings, and it runs through an apparatus that cleans it and makes it appropriate for use. Household rainfall catchment systems are appropriate in areas with an average rainfall greater than 200 mm (7.9 in) per year. Lebanon is one such country. There are several different types of rain harvesting systems, depending on what you want them for. I have already posted a diagram in which the system is designed to increase the level of groundwater. Here is one sample design in which the rainwater would be used for your home purposes:

Obviously, this design would be adapted slightly for the purpose of an apartment building, but you get the idea. It would save you money on water, help the environment, and help us maximize our resources to the maximum. Let’s start thinking about conserving and using our natural resources wisely. We can do it, Lebanon!!
