Rain Water Harvesting

Rainwater Harvesting and its impact on the environment

Rain water collection point

In my quest to improve people’s livelihood, I have adopted a deliberate approach of sharing information with my readers on how small acts of everyday life impacts the environment we live in and the benefits derived there in by individuals. The environment is important to each one of us and it is important that we take care of it by employing survival methods that are beneficial to all.

We should all know that the manner in which you take care of it today determines what becomes of it and the overall integrity for future generations.

My point for this write up is on rain water harvesting. When you collect rainwater, you have a direct positive impact on the environment that is visible to all to see. Rainwater is in most cases a free commodity and its collection obviously reduces water use from the utility companies. This has great benefit to individuals as it enables them to channel the money that would have been spent on paying the water bills to other pressing issues like electricity bills or even food. The utility company will also have a reduced servicing cost that reduces the number of its workforce and ultimately a reduction the wage bill/salaries.

Rainwater harvesting affects the environment positively in numerous of ways.

Expensive Dam

Rainwater harvesting is an alternative and cheaper water supply as compared to the normal surface water based supplies from reservoirs like dams or lakes or groundwater based supplies from open wells and bore holes.

Soil Erosion

Rainwater harvesting helps to reduce soil erosion through managing storm water runoff, flooding, and poor water quality in our lakes and streams by channeling to designated water collection points.

Water utility company

Collectively, rainwater has had a major impact on water supply and can be shown to be able to reduce water utility company water demand enough that need for establishing large new public water sourcing projects become unnecessary and less viable.

Paved surfaces cause rain water run off.

n urban settings, up to 90% of rain water runs off because of all the man made hard surfaces like roads, parking lots, paved yards and roofs. This is a very retrogressive trend that needs to be discouraged by the local authorities, instead people should be educated on the counter effects of such action and then made to know the benefits of reducing hard surfaces.

Irrigation using harvested rain water

Keeping the world green has a direct impact on the water cycle, ecosystems, and our ability to maintain balance with our surroundings. It is should therefore be everyone’s responsibility to play a positive role in keeping the world green. We all have heard or even experiencing the change in weather patterns, this should be wakeup call that we shouldn’t destroy the environment by employing good practices as we go about our daily activities. History is full of examples where deforestation and urbanization have totally changed the climates of large landmasses from the deserts or rain forests to even rivers and other natural resources that you can think of. If people could constantly engage in rainwater harvesting, the collected water and the eventual system created will do more than just beautiful environment, it helps maintain the water cycle which is cardinal for the continued water supply to communities.

Borehole drilling

Using open well water may be better than using city water supply for things like irrigation but it very directly depletes ground water supply. Taking water out of our lakes, reservoirs, and rivers also affects ground water. On the other hand, irrigating with rainwater helps replenish groundwater supplies hence the more reason we should engage in rainwater harvesting.

Water utility companies require a lot of chemicals for water treatment and pumping resulting high costs and high percentage use of energy. Rainwater systems reduce these costs and energy usage.

Weir making in progress

Rain water harvesting does not need a lot of resources in form of machinery or any other cost as may be related to such an activity, low income people from rural areas can easily undertake such a project using the very low cost equipment like hand hoes and shovels, ox driven ploughs or they could make weirs using local materials like sand to erect weirs that act as dam walls across a stream or anywhere where it is possible to tap water run offs.
