Rain Water Harvesting
#நீரின்றி அமையாது உலகு
What Is Rainwater Harvesting?
This usually entails collecting rain from a roof. Rain will gather in gutters, which will then direct the water through downspouts and eventually into a storage container. Rainwater collection systems can range from the straightforward to the complex, capturing rainwater into massive cisterns to meet your complete household's needs.
- A comparatively pristine and cost-free source of water is rainwater.
- It is socially and environmentally acceptable, encourages self-sufficiency, and aids in water conservation.
- You have complete control over your water supply (perfect for cities with water limits).
- Because it is not chlorinated, rainwater is healthier for landscaping plants and gardens.
- It also helps to lessen stormwater runoff from houses and businesses.
- It can address your property’s drainage issues and give you free water.
- It makes use of affordable, straightforward technologies that are simple to maintain.
- It can be utilized as a primary water source or as a backup for municipal water systems and wells.
- The system is simple to retrofit to an existing building or to erect while building a new house.
The 12 Steps Of Rain Harvesting
STEP 1
Understand your rainwater needs
- When it comes to Rain Harvesting, there are two operative words we use when determining more measurable goals – Quantity and Quality.
- How you plan to use your rainwater and how much you need for that use are the cornerstones in your decision-making when building an effective rainwater harvesting system.
STEP 2
Storing your rainwater
- Make the right choice for your property.
- Choose an appropriate storage vessel for your needs.
- A large, in-ground, concrete tank
STEP 3
Assess your collection area
- Use first flush diversion to channel, capture, and isolate the most contaminated rainwater from your roof to divert it away from your tank.

STEP 4
Filter out leaves and debris
- Keep leaves and debris out of your rainwater system.
- Prevent leaves and larger debris from entering the downpipes. These screens come in different grades, ranging from coarse to fine

STEP 7
Decide on a pump or gravity system
Find the best way to draw water from your tank depending on what your end use is.
- Decide on a pump or gravity fed system
STEP 8
Manage standing water
- By looking after the water sitting in your tank and pipework, you’re ensured great quality water.

STEP 9
Filter the final stage before use
Reduce sediment, colour, and odour from rainwater before use.
- Post-tank filter
STEP 10
Optimise your overflow
- Optimise your overflow to ensure your tank is always performing at its best, even during high rainfall events.
- Mosquito-proof screen
STEP 11
Monitor your water level
Dipstick Method : A long stick marked with measurements is inserted into the tank to manually check the water level.
- Record your usage to optimise your rainwater use.
STEP 12
Care for your system
- Inspect and clean filters (such as mesh filters or sediment filters) monthly. Replace filters when they show signs of wear or become too clogged to clean effectively.
