Catchment Surface: Rainwater Harvesting Term of the Week

This week’s word of the week is Catchment Surface. Generally a Catchment Surface is a roof of some type of structure. Pictured below is one type of many different configurations of Rainwater harvesting systems showing the roof as the catchment surface.
Catchment is defined as the following according to dictionary.com
the act of catching water.
something for catching water, as a reservoir or basin.
the water that is caught in such a catchment.
1840–50; catch + -ment
The square footage of your catchment surface or roof determines roughly how much water you can store. You measure your square footage by measuring the outside of your building on each outside wall. For example in the drawing below we have a very simple drawing to show the measurements. One outside wall is 30 ft and the other wall is 40 ft. Multiply these together to get your square footage of 1200 sq ft roof catchment surface. If the roof is guttered where it should be, then you can capture from this entire surface. If it is not guttered where it needs to be then the roof catchment surface is diminished by that factor.

It is important to have guttering installed properly and in the right places to ensure you can capture all the rainwater your catchment surface can provide. Did you know that you can even have the guttering installer put your downspouts in the right location when the gutter is installed? If you are unsure about whether you have the proper guttering to install a system designed to capture all the rainwater your roof can provide, give us a call. We specialize in estimating and designing a system that is tailored to your needs with maximized water efficiency in mind.

Next week we will discuss and define another Rainwater Harvesting System Term.  Follow our Blog so you don’t miss it! Thank you for sharing this info with your friends or people you think are interested in it.
