Write a speech on"Rain Water Harvesting"

Answer 1

Respected Parents of all the Children and My Dear Friends – Warm Good Evening to one and all!

Before I begin with my speech on Rainwater Harvesting, let me first extend warm thanks to all the parents for coming together under one roof and making our event a success. As we have been taught in our school the benefits of rainwater harvesting, all the children decided to spread the knowledge amongst their families and friends and enlighten everyone about its benefits.

Rainwater harvesting is an interesting method to collect and store rainwater for such uses as landscape irrigation, animal rearing, gardening, etc. When the rain comes, we never make any efforts towards preserving that water. The water can be collected from different hard surfaces, like terrace and/or other artificial aboveground tough surfaces. If the climate is dry, such as that of in South Australia, the technique of rainwater harvesting can prove to be extremely beneficial for the environment.

There are many rural households that have to conserve all the water for their property and rainwater more often than not offers comparatively a better quality supply to the household than river, dams or bore water. Rainwater harvesting however is not only meant for rural regions as many urban households too are joined to a reticulated, treated (mains) source of water supply. This method of rainwater harvesting can considerably bring down the use of main water sources.

Now, the question that arises is what are the advantages of rainwater harvesting? It’s one of the major benefits is that it will help you bring down your water bills, secondly you will have an alternative source of water supply during the situation of water crisis and thirdly it will help you maintain your green, blossoming garden. Excessive dependency on climate as well as tank size is not right and so rainwater harvesting can help reduce the burden drastically on the main sources of water.

Rainwater harvesting also helps overcome the fear of storm water runoff; thus reducing the risk of local flooding or scouring of brooks. You can collect rainwater from various rooftops, based on what quality of rainwater is required. For instance, if rainwater for lawn or garden irrigation is required, then

Collect it from any roof surface other than unsealed asbestosMake sure that all gutters are linked to the outletsPreferably attach a good screen of leaf to the guttersUse the outlets of gutter that can be adjusted at the bottom of the gutter

For other miscellaneous uses:

Do not let vegetation to hang from the roofClean the gutters as well as your roof before fixing the systemInstall a leaf screen made of good quality underneath the gutters or instead fix a leaf-shedding gutter.

For the purpose of drinking, please do not collect rainwater:

From roof sections which may contain asbestos sheeting or lead flashing and from terraces which are painted. If you cannot avoid this then properly seal the surface and paint it with a good quality roof sealant and avoid collecting rainwater from the initial periods of rainfall after sealing.In regions where airborne pollutants exist from nearby activities, like chemical processing and crop-dusting.

Therefore, the above mentioned measures should be taken in order to make a safe use of rainwater. 

Thank you.
