Water is an essential element when it comes to growing crops. A lack of water can make the farming process come to a standstill, and this is pretty much the reality of farming throughout the world. The best way to meet water deficiency is through the natural approach of collecting water from rain, with the monsoon season being the best time for it.
Rainwater harvesting is a feasible and inexpensive technology that involves collecting water from impervious surfaces/roof structures, enabling water self-sufficiency. The water gets collected in gutters, channeled into downspouts and storage vessels. It helps you deal with a significant part of your water needs throughout the year. You just need to follow the best practices for collecting and storing water. Based on your needs, you may use a simple rain barrel or large cisterns to collect water.
Benefits of Collecting Rainwater
- Rainwater is an absolutely free and clean water source
- Enables complete control over the supply of your water (perfect for regions with water limitations)
- Easily usable as a back-up source to emergencies, municipal water/wells, and main water source
- System is highly compatible with an existing structure and easily built during the construction of a new home
- Environment friendly and socially acceptable
- Limits storm water runoff from businesses and homes
- Helps solve water drainage problems
- Inexpensive and easy to maintain technology
- Helps conserve water and promote self-dependency
- Being non-chlorinated, it is apt for gardens and landscape plants
- Enhanced flexibility with modular nature allowing for expansion, reconfiguration, or relocation, if required
Make the Most of the Monsoon Season with the following:
1. Rainwater Barrels
It is probably one of the most common and familiar methods for collecting water across the world. For collecting water, all you have to do is install a barrel at the downspout of a gutter. The actual barrel might be a commercial rain barrel or a recycled one.
- Trouble-free implementation with little knowledge
- Easily adjustable since they require less space
- Readily available at various websites/stores and in your community
- Overflowing issues, wasting collection opportunities
- Limited general capacity of 50-100 gallons
2. Rain Chains
By installing rain chains, you can guide the water falling on the rooftop into the sump/recharge well. These chains are more of an alternative to conventional PVC closed gutter downspouts. Since they make an aesthetic addition to a garden or home, they are a pretty common sight. Although metallic chains are an ideal choice, there are other options available as well.
3. “Dry” System
Involving a larger volume for storage, this practice is a variation of the traditional set-up of a rain barrel. Eventually, the pipe for water collection ‘dries’ post every rain event due to the fact that water is emptied into the tank’s top directly.
- Large storage capacity
- Easy maintenance due to a less complicated system
- Ideal for climates where rainfall occurs with larger, infrequent events of storm
- Inexpensive implementation
- A must for the storage tank to be located adjacent to your home
4. “Wet” System
In this method, collection pipes are located underground to connect numerous downspouts from various gutters. The underground piping is filled by the rainwater, and the water comes to the top in the vertical pipes till the time it falls into the water tank. Also, it is essential that the underground collection piping and downspouts maintain water-tight connections, with the tank inlet’s elevation required below the lowest home gutter.
- Great ability to collect the water from complete collection surface
- No need to locate the tank close to your home
- Capable of collecting water from downspouts and multiple gutters
- Expensive implementation because of underground piping
- Enough difference needed between tank inlet and gutters
5. Catchment Ponds
It is also one of the traditional rainwater collection methods that involve an artificial pond making for collecting rainwater, enhancing percolation, managing flooding, and recharging groundwater. Water is retained temporarily that finally goes into the ground. These ponds are highly popular in residential areas where concrete surfaces are available to impede the water percolation into the ground.
6. Recharge Wells
Unlike borewells, recharge wells are known for collecting water and channeling it into the ground, leading to a recharged shallow aquifer eventually. The recharge well is designed with the help of precast concrete rings, and it normally goes to 3-8 meters in depth. They collect water from rooftops, roads, paved surfaces, and push the same into the ground to lift the water table. They are well suitable for residential communities and individual homes.
7. Green Roof
With this type of rainwater harvesting method, you do not need any middleman. There is no need to direct rainwater for tank storage and channel it into the ground; you can get a green roof installed on your home to let plants utilize the water right away.
A vital thing to keep in mind is laying down a roof protection lining, including a drainage system to manage the runoffs. Apart from this, with a green roof, you will be able to add home insulation and protect your roof against damage.
With every farmer trying to make the most of the monsoon season, it is imperative to figure out the best possible practice of rainwater harvesting for you and start preparing for the same. Yes, there may be a lot of speculations in your mind regarding the best practice to adopt or other framing concerns that may stop you from leveraging monsoon opportunities.
