How to Collect Rainwater

There are several ways to collect rainwater, and after reading you can decide which method is best for you.

Collecting Rainwater in a Barrel

This oldest, simplest, and easiest method to collect rainwater is in a barrel,  the barrel that’s used can be recycled followed by cleaning, or a new barrel can be purchased. Collecting rainwater in a barrel is the most common. This method is simply done by locating or installing a barrel at a gutter downspout which will collect the rainwater.

The Pros of Using Barrels

  • Can be easily installed with little effort
  • These barrels don’t take up much space which makes installation easy

The Cons of Using Barrels

  • Barrel will eventually get filled if it’s raining constantly and  overflow onto the ground
  • The water-holding capacity of rain barrels is limited, there is only so much water they can  hold

Collecting Rainwater In a “Dry” Water System

This method of using a dry water system involves the variation of a rainwater barrel setup that involves a larger storage volume, essentially the collection pipe “drys” after rain emptying directly into the top of the tank.

The Pros of “Dry” Water Systems

  • Is not complicated making these systems easy to install
  • Can be inexpensive to install
  • Is ideal for places where rainfall happens with infrequent, larger storm events
  • Can collect and store large amounts of water

The Cons of “Dry” Water Systems

  • The storage tank must be installed or located next to your home

Collecting Rainwater in a “Wet” System

The use of a wet system involves placing the collection pipes underground so that multiple downspouts can be connected from different gutters. Once it starts to rain the water will fill the pipes that are underground causing the water to raise in vertical pipes until it overflows into the tank. Ensure that the underground collection pipe and the downspout have connections that are tight to avoid water loss or leakage. The elevation of the tank inlet must be below the lowest gutter on the house.

The Pros of a “Wet” System

  • You have the option of locating  the tank away from your home
  • The advantage of collecting water from multiple gutters and downspouts
  • Gives you the advantage to collect water from the entire collection surface

The Cons of a “Wet” System

  • Sufficient difference between gutters and tank inlet must be available
  • More costly to install because of underground piping
