Question

name two methods by which rainwater harvesting is carried out?

Answer 1

HI,

Barrel
Installing a barrel on your property is the easiest and cheapest way to begin harvesting rainwater. Place the barrel under the downspout of your guttering so that the rain that falls on the roof of your property is diverted into the barrel. Typically the container will have a spigot at the base from which you can draw water to irrigate your garden. You can affix a hose to the spigot or even connect it to a drip irrigation system. Barrels are easily sourced, either new or recycled (if going for the latter option, check what the barrel has been used for to ensure no unwanted chemical residues remain inside) and simple to install. If you live in an area where mosquitos abound, it is advisable to place a lid on your barrel to prevent the insects laying their eggs in the water, while if you live in a location that experiences freezing winter conditions, you may want to disconnect your rainwater barrel during those months to prevent it from freezing and cracking. The major downside with the barrel method of rainwater harvesting is the limited capacity, which can lead to overflowing. You should also avoid using a barrel made from translucent material; a barrel that lets in sunlight is likely to grow algae inside, which can only be got rid of by the addition of chlorine, a chemical you don’t really want to be putting on your garden beds.

Dry System
It may seem odd to talk about a ‘dry’ system when discussing water capture, but this method is a recognized strategy, and so-called to differentiate it from the ‘wet’ system below. The dry system of rainwater harvesting is essentially the barrel system scaled up in size. A larger container is placed next to the property, offering a larger storage capacity than a barrel, and the guttering is diverted to the top of the tank. Like the barrel method it is reasonably cheap and easy to implement. It gets the name ‘dry’ because essentially the collection pipe ‘dries’ after each rain event, since it empties into the top of the tank. This makes it a good choice for plots in areas prone to infrequent but large storm events.
