Jalsandharan Project



Objectives

  • To improve water availability through this project.
  • To manage the available water resources.

Why and How

Agriculture is the backbone of India’s economy. As a nation, we ought to be proud of the farmers who sweat it out in the fields to produce the crops that make up our meals. Indeed, the Indian farmer has the capacity to feed the entire nation if properly trained and given equal prospects.

However, in reality, it shows a very different, dismal picture. Natural calamities like drought and floods make the crops, and ultimately the farmers, suffer. The loss is unbearable as these calamities are occurring more often these days. Being at the mercy of nature is bringing the losses for farmers at most of the times, especially farmers from the low rainfall region.

To fight against these conditions, Lokmangal Foundation has initiated Lokmangal Jalsandharan Pattern B.B. This pattern is the irrigation scheme mainly to improve water availability. After thorough research, we design the plans to manage the water resources in a particular area. We take the necessary measures to turn those plans into reality.

This project has turned out to be a huge success wherever it has implemented. With this project, water availability for farming has improved, per ton yield has boosted up, water table has enhanced and the farmers from respective regions are appreciating the prosperity. We are happy that with our small efforts we can bring the smiles on the faces of people who feed us. We are aiming to eradicate the issue of water availability from most of the regions.

NEED OF THE HOUR – USE, CONSERVE & MANAGE WATER PROPERLY BECAUSE EACH & EVERY DROP COUNTS.





Jalsandharan Lokabhiyan


1. Hipparga Lake Rejuvenation



Objectives

To increase the storage capacity of Hipparga Lake by removing silt (black soil) from a 26 km long stretch along the sides of the Hipparga Lake and distribute it to the farmers for free. The soil is lab tested and is excellent for the cultivation of crops. We plan to remove at least 1.25 lakh trucks of soil in the current season.


Description

Hipparga Lake is the largest water reservoir near Solapur city. It was built circa 1866. The total storage capacity of the lake is 3.33 TMC. But the excessive accumulation of black soil over the years has resulted in the reduction of storage capacity by almost 45%.


Details

  • Construction: around 1866 to 1871
  • Storage capacity: 3.33 TMC (94.30 million cubic meters)
  • Dam length: 2134 meters
  • Dam breadth: 7.60 meters
  • Dam height: 24.45 meters

Water Usage:

  • For drinking purpose: 14.55 million cubic meters
  • For industries purpose: 0.10 million cubic meters
  • For cultivation purpose: 46.51 million cubic meters

Black Soil (Slit) Presence:

  • 26.44 million cubic meters (according to the survey done by Maharashtra Engineering Institute, Nasik, 1991)
  • 32.36 million cubic meters (according to the survey done by Maharashtra Engineering Institute, Nasik, 2002)
  • In 2016, approx 42 million cubic meters of slit is expected to be present which makes around 45% of the total storage capacity.
  • (Note: 42 million cubic meters = 26,00,000 trucks (1 truck = 5 brass))
  • Project duration: from 5 January 2016 to 5 July 2016
  • Budget rates: Black soil loading by excavator – 300 per truck
  • Transportation: 150 per km
  • Total cost (up to 10 km)
  • 1500 + 300 = 1800
    1800 * 26,00,000 = 468,00,00,000
    (Note: All figures are in INR.)

Comparative Analysis

Description
Before the Project
After the Project
Siltation Huge amount of siltation leading to reduced water holding capacity. Low siltation leading to the increased water holding capacity.
45% of Total Capacity i.e. 130 lakh Brass Removed 8.05 lakh Brass
Water supply Once in 4 days Once in 2 days
Site nearby Nearby areas were covered with weeds and dry grass. Nearby area is cleaned and developed with some green plants. This site in future will be developed as a picnic spot in ‘Smart City’ development project by Government.
Crop yield Poor Increased due to the proper water supply and use of manure-rich siltation
Remarkable Increase in water level


2. Bibi Darfal


A. Canal Construction


Objectives

To suggest further extension in the scope and recommend some upcoming technologies and programs that can be used. This project demonstrated the benefits of proper water management. Also, this project was not just limited to constructing of canals but also included removal of siltation in lakes so as to increase its water holding capacity and building of recharge water shaft. In addition to quenching parched fields and throats, the project has also become a model for others to adopt.


Description

Bibi Darfal is the longest known canal constructed by the Lokmagal Foundation. The entire process included the following steps: · Appropriate selection of site based on the water needs · Arranging the required funds · Getting the required approvals from the Government and the farmers of the fields from where the canal flows · Constructing the new canal by cleaning and enlarging the capacity of an existing canal (The capacity is increased by deepening the bed and enlarging the bed width.) · Constructing embankment at appropriate locations on the canal


Details

  • Length of canal: 15 km
  • Width of canal: 25 meter
  • Depth of canal: 2-3 meter
  • Water Capacity: 750 Cr litre
  • Number of embankment: 7 (5 newly constructed named as Bhagirath Sagar, Nath Sagar, Ganga Sagar, Shiv Sagar, Krishna Sagar; renewed 2 old embankments by cementing)
  • Total irrigated land: 1500 hectare

B. Recharge Water Shaft


Description

In the rainy season, village canals are filled up but water doesn’t percolate due to siltation in the canals and this water gets evaporated after some months. Recharge shafts were installed in the channel of Bibi Darfal water conservation project by Lokmangal Foundation. By constructing recharge water shafts in canals, this water is recharged to groundwater. Top of the shaft is kept at half of the full supply depth of tank. Shaft is filled with filter material like boulders, gravel and coarse sand. Shaft should end in more permeable strata, below the top impermeable strata.


Details

  • Distance between two shafts: 100 meter
  • Diameter of shaft: 6 inches
  • Depth of shaft: 80 feet
  • Volume covered by boulders, gravel and coarse sand: 6 X 6 X 6 ft3
  • Casing pipe depth: 20 feet

Comparative Analysis

Description
Before the Project
After the Project
Width of canal 5m 25m
Depth of canal 1.2 m 2.2 m
Total water capacity 75 Cr. litre 750 Cr. litre
Water availability Canal was dry throughout the year except during rainy season when it used to overflow. Canal has water for around 8-9 months in a year and does not overflow during rainy season after widening the depth and width.
Water storage Water storage was very less. Water storage has increased tenfold.
Number of embankment 2 7
Crop yield Poor Increased by around 35% especially for sugarcane
Remarkable Increase in the groundwater level due to the use of Recharge Water Shaft.
