Which Water Collection Method is Right for You?

It’s important to be mindful of your personal water needs and the availability of clean water in the areas where you live. Collecting rainwater is a popular way to meet these needs, but it may not always be an option for everyone. This article will discuss some different collection methods that can help you get started on meeting your water needs.

What are Crucial Components of Water Collecting System?

While each water collecting method is unique, there are some components that every system should include. These include A gutter or barrel to collect rainwater (and any runoff) from the roof; a way for the collected water to drain into your holding container of choice; and an overflow catchment area in case more water than expected ends up in the system.     

Do You Need a Water Pump? 

Some water collecting methods require a pump, while others do not. A pump can be useful for moving collected rainwater from the holding container to your home or storage tank. If you plan to collect enough rainwater to meet all of your needs through one system alone, then this should not necessarily be included in your design.     

Water Collection Methods: Comparing and Contrasting

Many people choose to collect rainwater because of the convenience factor. If you live in a region where it rains frequently, collecting water is easy and efficient. However, if your roof cannot handle an adequate amount of runoff or there isn’t enough space for gutters at every downspout, you should consider other options.   

If your home or landscape can accommodate gutters and a storage tank for rainwater, then this is likely the best choice for you. It’s also an inexpensive way to collect water.   

Point-of-use systems are another popular option because they allow you to collect water directly from the downspouts that feed into your gutter system.   

These systems are good for small spaces and do not require electricity to function, but they tend to be more expensive than other options due to their individualized parts (like a filter) and complex design.  

Which Water Collection Method is Best for You?

The best water collection method for you will depend on your location, personal preferences, and needs. If you’d like to get started with collecting rainwater but don’t want to invest a lot of money or if your rain gutters aren’t suitable for collecting large quantities of water, a rain barrel may be the right choice. If you have a larger budget and want to collect more than one or two barrels worth of water at once, a cistern may work well.

Sand, Gravel, and Charcoal Filter 

One popular method of collecting water is a sand, gravel, and charcoal filter. This is an easy collection method that doesn’t require any tools or special equipment to carry out effectively. To make this type of filter you will need:    

  • Two five-gallon buckets with lids (one lid should be slightly larger than the other to allow for a space 
  • A drill bit is sized one inch larger than the diameter of your bucket’s opening. 
  • Sand (enough to cover half of the bottom space in each container)  
  • Gravel (small enough that it can pass through a one-inch hole, but large enough to 
  • Charcoal    

The filter is created by drilling holes in the bottom of the larger bucket and filling it halfway full with sand. The smaller container will be used as a strainer, so this needs to have small holes drilled around its base that is large enough for gravel to fall through    

The smaller bucket is then placed into the larger one and filled with water after it has been poured from a higher elevation. The large holes drilled in the bottom of the upper container allow gravity to help push clean, filtered water down into the collection bucket below.    

Downspouts 

Another one of the most popular methods for collecting rainwater is through downspouts. This method can be used by those who already have gutters or other water collection features on their roof and may not require any extra investment in equipment.    

To set up a system that collects water from your downspouts, you will need    

  • A drill with a one inch bit   
  • Downspouts that are elevated above the collection area by at least two feet. This may require installing new downspout extensions or drainage systems for your gutters if they currently end near where you’d like to set up the water collecting system   

     – A collection area that is elevated by at least one foot. This can be a raised garden bed, flower planter, or other device containing soil where the water will readily absorb into the ground below instead of draining away from your home’s foundation and causing flooding near your doors.

This method works best if the gutter downspouts are connected to a single opening.   

Be sure that there is enough space between each opening for water runoff from two or more downspout openings to pool together and drain into your collection area without overflowing onto hard surfaces such as sidewalks, patios, or streets below.   

Rain Barrel

A rain barrel is another popular and cost-effective way to collect water. A 50-gallon drum or other storage container filled with topsoil can be used as a planter that collects runoff from your roof gutters.   

The opening of the collection vessel needs to face towards where most of the rainfall occurs on your roof    

You can also attach a downspout diverter to your existing gutter system that will direct the flow of water into your rain barrel instead of allowing it to continue on its current path. This method has the added benefit of preventing overflow in times when rainfall is especially heavy or during snowmelt season for those who live in colder climates.

Earthworks

A more advanced collection method requires the use of earthworks to direct and collect rainwater runoff. This is a system that redirects water away from your foundation and towards plants or trees on your property.   

This isn’t for everyone, though, as it can be difficult to manage correctly even with professional assistance if you aren’t familiar with the layout of your property   

This method is only recommended for those who have a lot of lands to work with and are willing to put in some extra effort during installation.   

Swales, Ditches, and Channels  

A swale is a shallow trench that directs water runoff into a nearby garden   

This is a great way to allow water that would otherwise drain away from your property to be used by the plants and trees on your land.   

A ditch can also act as an earthwork, but it directs water into drainage areas or ditches further away rather than towards another location on-site like with a swale   

A channel is a more elaborate version of a ditch that directs water over an area, such as to create a waterfall feature.   

These can be difficult and expensive to install without professional help or specific knowledge about how the system works.   

Be sure you know what you’re doing before attempting to set up an earthwork water collection system   

These are just a few of the ways to collect rainwater for your home.    

Catchment Structure 

Finally, a catchment structure is another popular method of collecting rainwater runoff. This involves taking an existing water collection feature on your property and modifying it to include new drain openings that are placed slightly lower than the rest of the area so that they catch all of the rainfall or snowmelt running off from higher elevations    

There are a number of different catchment structures that can be used for this purpose, including:   

  • Patios and sidewalks   
  • Overflow gutters from your main roof system

These should have built-in spouts at the lowest point to direct water into the collection area below.

  • Aquariums and other enclosed glass or plastic tanks   

The water collection system will work best if the tank has a spout that can be turned on to allow flow to occur. This means building one yourself, such as creating an opening in the side of your aquarium with fiberglass insulation and sealant for waterproofing   

  • Water features   

If you already have a water feature such as a fountain or waterfall on your property, the runoff from this can be directed into your rain barrel to create even more non-potable (drinkable) water for use in your garden and other outdoor areas.   

The most important part of setting up a rainwater collection system    

Make sure that the water entering your tank will not harm any plants or animals.   

For example, if you are using an aquarium as your catchment structure then it is important to know that most glass or plastic tanks do not have an internal overflow system   

This means that if your tank fills up to a certain point, it could begin spilling over the top and draining out onto hard surfaces.

Aquatic life in this water will be at risk of dying. To prevent this problem, use only tanks with built-in overflow systems   

This means you will have to research the type of tank that best suits your needs before purchasing one for this purpose.   

In summary, there are a number of methods available for collecting rainwater runoff from rooftops and other hard surfaces above ground level at your home or business    

It is important to select the one that works best for your specific needs and existing water collection system.   

For example, if you already have gutters in place on the outside of your home or business then it will be easiest to connect them directly into a rain barrel or other storage vessel   

However, if you do not have gutters in place then it may be best to use a catchment structure that does not require modification or alteration of your existing system   

Other considerations include cost, the amount of rainfall at your location, and how much water storage is required. There is also the added benefit of being able to use your rainwater collection system for irrigation   

For example, if you have an existing spray nozzle or soaker hose connected to the storage vessel then it will be easier to manage how this water is used.   

All of these factors should be considered before purchasing a new catchment structure with drain openings that are lower than the rest of your water collection area   

This will allow you to use any runoff from rainfall or snowmelt for irrigation purposes.   

In this way, a rainwater harvesting system can be used in conjunction with other forms of landscaping and gardening that rely on natural precipitation patterns. 

Other Collection Methods    

There are other methods available for collecting water that you can research on your own. These include using cisterns or barrels fitted with spigots to collect rainwater, installing an irrigation system (particularly if the area where you’ll be planting is large), and more   

All of these methods are effective for collecting water but you may need to consider your specific goals, budget, and situation when deciding which is the best option. For instance, cisterns or barrels that have spigots can be used not just for irrigation but also for washing vehicles. 

However, they are not the best option for collecting water that will be used to irrigate plants.
