The shift from rural to the urbanized world in the past decades has led to tremendous loss of natural vegetation in the cities. One of the dangerous water pollution issues that has concerned environmentalists is that of storm water runoff. In the industrialized world, runoff problem has worsened in the last few years.
When water that precipitates on the ground is not absorbed, it makes way through the yards, streets, driveways, gardens, parking spaces, lanes and every possible path it can get to reach the storm sewers and through it to small lakes, rivers near communities, cities or towns.
Storm water runoff carry with them chemicals, pesticides (through gardens) and other deposits that block streams and degrade the water quality, making it unfit for drinking.
Moreover, runoff also increases the risk of flooding and it makes matters worse when it comes to maintaining groundwater levels, leading to water shortages in many areas. To avoid this problem, rain gardens are brilliant options for homeowners to help communities tackle the task of poorly managed storm water runoffs.
The vegetation planted in rain gardens soaks up the water and the water filters in the ground. This is exactly the opposite of what happens in runoffs, the water enters the storm drains causing pollution in nearby water bodies like rivers and lakes.
The problem is compounded when runoffs from every home reach to water bodies damaging the water quality. Building a rain garden is a task that requires a little bit of research and planning from your side.
Rain Garden Benefits
Rain gardening is crucial for maintaining a better and healthy water surrounding in our living area. Here are some vital benefits of rain gardens.
No harmful pesticides or chemicals from the lawns flow along with the storm water to pollute rivers.
Helps in Restoring Underground Water Level
Local and regional underground aquifers or underground water levels are recharged with water, as the water seeps into the ground after being soaked by the soil.
Lowers Flooding and Drainage Problems
As aforementioned, runoffs lead to flooding and worst drainage problems in communities. Rain garden plantations can help us avoid problems like that.
No Mosquito Breeding
Stagnant water in driveways, rooftops is a haven for mosquito growth. When water is filtered through the soil and is soaked in the ground, there are no issues of mosquito threat.
Prepare Us for Drought Seasons
For drought prone area or in places where water shortage is an issue, rain gardens are very beneficial as the underground water level is not lowered due to recharging with filtered water.
Rain gardens are certainly a great choice for all gardening lovers and homeowners. Ask your friends or family members to provide some labor and your rain garden will be ready with very less efforts. If such little efforts and planning can help us save our water bodies and build a healthy environment, it is the right time to incorporate them in our homes.
