Frequently Asked Questions

  • Rain Water Harvesting
    • Is RWH only feasible for new buildings?

      No, old and existing buildings can also implement RWH. This can be done by modifying the existing plumbing and making additions, which will be checked by experts and they will provide the plan of action building wise.

    • What are the basic components of an RWH and conservation system?
      • Catchment areas - roofs of buildings and open spaces.
      • Storage units - a barrel, a tank, or a sump.
      • Conveyance mechanism - to transport the water falling on the catchment area to the storage unit.
    • What are the characteristics of a good RWH system?

      The RWH system should ensure that not a drop of rainwater falling within the premises is let into the sewerage or wasted as runoff. This can be achieved only if the method chosen, satisfies the following criteria:

      • Completeness: Both rooftop and driveway runoff water must be harvested.
      • Proper design: Volume of water and the nature of the soil in the area should be considered.
      • Maintainability: Design should incorporate features allowing for periodic maintenance of the structure.
    • Does it require a lot of maintenance?

      No. Once or twice a year, at very little cost.

    • How much rainwater should I harvest?

      The short answer is, how much ever you need! Past water bills will help you decide the same.

    • Can the stored rainwater in storage tanks be used for cooking and drinking?

      Yes. Some impurities from the dust, leaves or surfaces the water comes in contact with, may exist. But, they do not cause any harm as long as the water is boiled before consumption.

    • Can we recharge a borewell directly with rainwater?

      Clean and safe rainwater can recharge the borewell aquifers to increase the yield and availability. But, it is advised to consult a professional before attempting to do the same, since purifying the rainwater before the process might also be a part of the process.

    • What is a recharge pit? Is it the same as a recharge well?

      A recharge pit is a hole dug in the ground, usually filled with gravel or jelly to give it structural strength. However, a recharge well is not filled with gravel but needs concrete rings installed in it to stabilize its walls.

    • How do you create a cement ring well?

      The steps to be followed are:

      • Dig the ground in a circular shape (3 or 4 ft diameter) to the required depth (minimum 10 ft.)
      • Insert precast of cement rings to avoid caving in of the inside soil.
      • Fill up the remaining gap around the rings with aggregates or boulders.
      • Cover the mouth of the pit with a mesh
      • Rainwater is allowed directly into the well which in turn recharges the groundwater table.
    • What are the points to note while using a PopUp Filter for Rooftop rainwater harvesting?
      • PopUp Filter must be installed vertically.
      • PopUp filter of 110mm can handle rainwater from a maximum of 1000sq. Ft. of roof area
      • Keep the PopUp filter dry during nonrainy days by opening the flush valve to release stagnant water.
    • How does one collect water from a flat roof building?

      The flat waterproof roofs should be made to have a small slope towards the downtake pipes. These pipes then lead the water to the purifying mechanism.

    • How does a sand bed filter work?

      Sand bed filter is a method where coarse riverbed sand, pebbles and aggregates are filled as layers, one above the other. Rainwater is allowed at the top and filtered water is drawn from the other end.

    • What is water purification?

      Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water.

    • What is reverse osmosis and how does it help purify water?

      Reverse osmosis is a process where water is rid of impurities, using a semi-permeable membrane at high pressure. The pressure applied will force the water through the membrane, which does not allow contaminants to pass. Hence the water that has passed through the membrane is free from impurities.

    • How long should one boil water to kill bacteria and make it safe for drinking?

      Near sea level, a vigorous rolling boil for a minute is sufficient. At high altitudes, three minutes is recommended.

    • Does coromandel care arrange RwH for all requested sites?

      Coromandel Cares can help you plan and find the right experts to implement RwH in your location. You can contact us on our toll-free number 1800 425 6001 to know more. Once the team is assigned, they will visit your site, complete the inspection and provide a detailed quote for your RwH implementation.

    • Why is Coromandel Cares getting into RwH?

      Coromandel Cares is a community initiative of Coromandel King - the flagship cement brand of The India Cements Ltd - with a vision of building cityscapes responsibly. our interest is in enabling and driving sustainable practices even as we help build and grow our cities. in this context, we have tied up with experts who can guide those who wish to complete RWH or also engage in urban greening. this is our way of contributing positively to their communities and networks we do business in.

    • How does one fix rainwater harvest at their homes?

      RWH is a simple process to retrofit your house. You may follow the steps given below:

      • Select one or two down pipes carrying most of the rainwater from your roof.
      • Interconnect them
      • Add a wall-mounted rainwater filter to the end of the pipe
      • Connect the filtered water outlet of the filter to your underground water tank
    • If one gets water from the local corporation, why should one do rainwater harvesting?

      Supply from the corporation is limited. If you can do rainwater harvesting, then you do not have to depend on just water from your corporation. This allows for more houses to receive the corporation water.

  • Seed Bombs
    • What is a Seed Bomb?

      It is a seed inside a ball of charcoal dust, mixed with the required ingredients.

    • How does one plant a seed bomb?

      Seed bombs don’t need planting or complex propagation – just scatter them where you want them to grow (preferably on top of soil or compost), and let nature take over! It really is that simple! Seed bombs will also grow equally well in pots or other planters.

    • When can one scatter the Seed Bomb?

      Seed bombs can be scattered at any time of the year. One can choose seeds that will grow all throughout the year.

    • Where can one scatter Seed Bombs?

      Seed bombs can be scattered on top of soil or compost in your garden, and ideally in a nice sunny spot. If they are being scattered in public property the right permission needs to be taken from the authorities.

    • Do the Seed Bombs need to be broken up?

      No. The seed bombs should be left intact. Once the water has permeated the clay, the seeds will slowly begin to germinate inside the ball. Scattered seed bombs should not be picked up once it has rained, as this could damage any growing roots.

    • Does one need to water the Seed Bombs?

      If you scatter the seed bombs outside there should be no need to water them. Just let nature take over! Having said that, do bear in mind that watering will certainly speed up germination and early growth. If your seed bombs are inside or under cover then you will need to water them every 1-2 days.

    • How many seeds in a Seed Bomb?

      We have only one seed per bomb.

    • Do’s and Don’ts of Seed Bombs.
      The do’s of Seed Bombs.
      • Plant in an area that meets non biotic conditions.
      • Favour areas that are secluded from animals.
      • Obtain permission before planting in common/public areas.
      • Attempt to fill vacant spaces with greenery where feasible.
      The Don’ts of Seed Bombs
      • Do not throw in agricultural land, it hinders crop growth.
      • Do not ignore once planted - keep a check on it every now and then
      • Do not throw at people or cause property damage
      • Do not throw on land where conditions are harsh eg: Arid Land
    • How do I obtain Seed Bomb from Coromandel Cares initiative?

      You can request our seed bombs for yourself or gift to a loved one who is building/setting up their own home. Simply fill our request form here (hyperlink to form) or call our toll free number 1800 425 6001.

    • Why do we need seed bombs?

      In cities like Bengaluru, rapid urbanization has cost the city to lose its green cover at an alarming rate. Seed Bomb methods are the best ways to re-green as it required community participation and isn’t dependent on government initiatives. Replanting the trees is not a difficult process, we only need the will to do it.
