How is rainwater harvesting done in Gujarat?
Bhungroo helps farmers in such rain-scarce and salinity-prone areas. The system consists of a pipe erected in such a way that excess water passes through it, gets filtered and accumulates in an underground well. Later, farmers use a motor to pump the water up and use it for irrigation.
What is meant by rain water harvesting ‘?
Rain water harvesting is collection and storage of rain water that runs off from roof tops, parks, roads, open grounds, etc. This water run off can be either stored or recharged into the ground water. A rainwater harvesting systems consists of the following components: storage tanks and/or various recharge structures.
Which water is recharged by rooftop rainwater harvesting technique?
Underground Water is the answer.
What is Bhungroo technique?
Bhungroo (meaning “straw” in Gujarati) is an innovative water harvesting technique for irrigation introduced by Indian women farmers. It frees excess water from flood prone and waterlogged farmland by drawing all the excess water underground and making land accessible for farming.
Which water harvesting structures are found in Gujarat?
Western Coastal Plains : Traditional Water Harvesting Systems. Virdas are shallow wells dug in low depressions called jheels (tanks). They are found all over the Banni grasslands, a part of the Great Rann of Kutch in Gujarat. They are systems built by the nomadic Maldharis, who used to roam these grasslands.
What are the two methods of rainwater harvesting?
There are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting.
What are the types of rainwater harvesting?
The different methods of rainwater harvesting include:
- Rooftop rainwater harvesting.
- Surface runoff harvesting.
- First, flush.
- Transportation.
- Catchment.
- Filter.
What is the most common use of rooftop rainwater harvesting?
2. RRWH for groundwater recharge. The rainwater collected from the rooftop can be used for recharging the groundwater aquifers by various kinds of structures to ensure percolation of rainwater in the ground instead of draining away from the surface.
How do you collect roof runoff?
Direct collected water to stable areas. Dump roof runoff water into natural undisturbed areas with thick plant growth. If there is no natural area downhill, grow a strip of plants across the slope. Plant the filter strip with thick grasses or grow a buffer with a combination planting of grasses, shrubs and trees.
How can we use rainwater harvested by us?
Rainwater harvesting differs from stormwater harvesting as the runoff is collected from roofs, rather than creeks, drains, roads, or any other land surfaces. Its uses include watering gardens, livestock, irrigation, domestic use with proper treatment, and domestic heating.

What is the use of Bhungroo system?
Bhungroo helps farmers in such rain-scarce and salinity-prone areas. The system consists of a pipe erected in such a way that excess water passes through it, gets filtered and accumulates in an underground well. Later, farmers use a motor to pump the water up and use it for irrigation.
How much water does a Bhungroo add to the soil?
400 to 2,100 millimeters, in salt affected and seasonally eroded soil. Using only one square meter surface area, each Bhungroo augments 1 to 4 Mlts of water/year and allows farmers to retrieve stored water. Multiple Bhungroos with a serial injection model can be used in flooded areas to capture and store excess water.
How Bhungroo helps farmers in rain-scarce areas?
This leads to water logging and the standing water again increases the salinity of the soil. Bhungroo helps farmers in such rain-scarce and salinity-prone areas.
What is Bhungroo in Gujarati?
Bhungroo is a term in colloquial Gujarati meaning a straw or hollow pipe. During monsoon, Bhungroo is used to harvest the excess water available during storms and waterlogging. It is an efficient rain water conservation technology by use of pipes of 10 to 15 cm in diameter.
