Water Conservation and Traditional Water Harvesting in Rajasthan


1. Water Scenario of Rajasthan & The Philosophical-Scientific Classification of Water

1.1 Hydro-Geological Background and the Magnitude of Water Scarcity

Rajasthan is India's largest state by land area, occupying **10.41% (3,42,239 sq. km)** of the nation's total geographical expanse. In stark contrast, its endowment of natural water resources is extraordinarily scarce: - **Share of India's Total Surface Water:** Merely **1.16%** - **Share of India's Total Groundwater:** Only **1.72%** - **Demographic Pressure:** Supports approximately **5.66%** of the country's human population and over **10.60%** of its livestock. - **Precipitation Distribution:** The state's long-term average annual rainfall is approximately **57.51 cm**, characterized by extreme spatial volatility—plunging to **10–15 cm** in western Jaisalmer while exceeding **100 cm** in southeastern Jhalawar and **150 cm** at Mount Abu (Sirohi). - **Aridity and Drought Frequency:** Spanning the Thar Desert over 60% of its territory, rainfall is erratic, localized, and concentrated in a handful of high-intensity downpours. Historically, rainwater harvesting in Rajasthan was not merely an engineering expedient; it was an existential socio-ecological imperative and an inviolable cultural ethic.

1.2 Anupam Mishra's Philosophy & The Threefold Classification of Water

Gandhian environmentalist **Anupam Mishra (1948–2016)**, in his masterworks **"Aaj Bhi Khare Hain Talaab" (1993)** and **"Rajasthan Ki Rajat Boondein" (1995)**, meticulously documented the indigenous hydrological wisdom of Rajasthan's desert communities. Traditional society categorized water into three distinct geological and perceptual forms:
Form of Water Geological Occurrence & Source Quality & Utility Principal Harvesting Structures
1. Paalar Paani (पालर पानी) Rainwater falling directly from the clouds and running across the pristine surface. Purest naturally occurring potable water; zero salinity; the nectar of life. Tanka, Kund, Nadi, Talab, Bawari.
2. Paataal Paani (पाताल पानी) Rainwater that percolates past surface strata into deep underground bedrock aquifers. Frequently brackish, highly mineralized, high in fluorides, nitrates, and dissolved solids. Deep dug wells (Kuan), Tubewells.
3. Rejwaani Paani (रेजवाणी पानी) Rainwater that sinks into the surface sand but is halted above deep saline aquifers by an impermeable gypsum/kankar hardpan. Exceptionally sweet, cool, and potable; suspended as capillary moisture in sand strata. Kui (कुईं) or Beri (बेरी).

The Concept of 'Rej' (रेज):

- In the Thar Desert, precipitation was traditionally quantified not by standard inches or millimetres, but by **'Rej'**—defined as the precise quantum of rainfall required to saturate the sandy topsoil to a depth of 5 to 6 fingers (*angul*). - When a 'Rej' shower occurs, the sand locks this moisture within its porous grains. The presence of an underlying **gypsum hardpan (Kharia Patti)** prevents this pristine water from sinking into the lower, highly saline groundwater table (*Paataal Paani*). This perched, entrapped moisture is then slowly harvested drop-by-drop through narrow shafts called **Kuis**.

2. Traditional Desert Water Harvesting Structures

2.1 Tanka (Taanka)

The Tanka is the quintessential household and community subterranean rainwater cistern of the Thar Desert, ubiquitous across Barmer, Bikaner, Jaisalmer, Jodhpur, Nagaur, and Phalodi.

                        └─────────────────────────┘

Structural & Technical Specifications:

1. **Dimensions:** Typically a cylindrical or rectangular underground pit dug **15 to 20 feet deep** with a diameter of **8 to 10 feet**. 2. **Agor / Paitan (आगोर / पायतान):** The designated circular catchment surrounding the tanka. It is plastered with a paste of local clay, murrum, lime, ash, or cow dung to maximize runoff coefficients and prevent infiltration before water enters the cistern. 3. **Jagoti (जागोटी):** The engineered slope of the Agor that funnels collected rainwater directly toward the cistern mouth. 4. **Filtration Mechanism:** The inlet features fine metal mesh or cloth screens, preceded by a miniature silt trap chamber where heavier sand particles settle out. 5. **Inner Lining:** Traditional tankas are lined with indigenous lime (*Chuna*) and wood ash, which naturally disinfects stored water, keeps it cool, and arrests bacterial growth. Modern designs utilize RCC or masonry plastered with waterproof cement. 6. **Aperture & Security:** The cistern is capped with a secure, lockable hatch to eliminate evaporation losses and prevent contamination. 7. **Storage Capacity:** A standard family tanka stores **20,000 to 50,000 litres**, providing an uninterrupted potable water lifeline for a family of 6–8 members across the 9–10 dry months between monsoons.

2.2 Kund / Kundi

A Kund is an engineered variant of the Tanka constructed predominantly across the sandy plains of Churu, Bikaner, and the Shekhawati tract where undulating dunes preclude natural rocky catchments.

Key Structural Differences from Tankas:

- While a Tanka often capitalizes on natural slope or residential courtyards, a **Kund** is built in open pastures or fields by constructing an expansive, elevated, artificial circular catchment apron (30 to 50 feet in diameter) paved with lime mortar or cement. - **Domed Superstructure:** The mouth of the underground cistern is crowned with a 3 to 4-foot-high masonry dome (*Gumbad*) featuring a lockable iron trapdoor. - This domed enclosure prevents wind-blown desert sand from falling into the reservoir and serves as a vital water station for grazing herds and pastoral nomads.

2.3 Kui or Beri

The Kui is universally acclaimed as the most ingenious hydro-engineering marvel of Rajasthan's desert dwellers. It is completely distinct from a standard well.

Structural & Geological Mechanics:

1. **Dimensions:** An extremely narrow circular shaft measuring only **3 to 4 feet in diameter** (barely enough room for a single person to squat) and excavated **30 to 60 feet deep**. 2. **Geological Prerequisite (Kharia Patti):** A Kui can only function where a subterranean layer of **gypsum / calcareous clay (खड़िया पट्टी)** runs horizontally between 30 and 60 feet below the surface. This impermeable stratum holds perched capillary water while sealing it off from deeper saline aquifers. 3. **Functionality:** A Kui does not intersect the true water table. Instead, it creates a vertical collection column into which microscopic moisture trapped in the sand slowly oozes via capillary seepage. The ultra-narrow diameter ensures minimal surface area, suppressing evaporation under severe desert temperatures. 4. **Harvesting Yield:** A typical Kui yields merely **2 to 3 pitchers (Ghada) of water per day**. In the cool morning hours, village women lower a small leather or rubber pouch (*Chadas / Dolchi*) to draw this sweet, chilled Rejwani water.

The Craft of Chejaaro:

- **Chejaaro (चेजारो):** Master craftsmen specialized in digging and lining Kuis. - **Basoli (बसोली):** Because shovels cannot be swung within a 3-foot radius, the Chejaaro sits cross-legged, chipping away at the compacted sand and kankar with a handheld, short-handled iron pick-axe called a *Basoli*. - **Casing Techniques:** To prevent instant collapse of loose sandy walls, the Chejaaro weaves a continuous circular rope binding using coarse fibres of the desert shrub **Kheemp (Crotalaria burhia)**, known as *Choli*. This rope coil is wound tightly against the circular shaft as excavation progresses downwards. Where dressed stones are available, dry-stone interlocking masonry is employed.

2.4 Nadi

The Nadi is the oldest, most common community surface water harvesting pond constructed across rural Thar.

Historical Genesis & Mechanics:

- **Historical Evidence:** The earliest documented historical construction of a planned Nadi dates to **1520 AD**, commissioned by **Rao Jodha**, the founder of Jodhpur (*Jodha Ji Ki Nadi*). - **Siting:** Constructed at the natural convergence of undulating sand dunes or hills by raising a crescent-shaped earthen bund (*Paal*). Water depth averages 3 to 12 feet. - **Madaar (मदार):** The designated catchment area feeding the Nadi. By community decree, the Madaar is kept strictly sanctified—defecation, grazing, or tree felling is prohibited within its boundary. - **Nehta (नेहटा):** The natural or stone-pitched surplus spillway allowing overflow to safely discharge during torrential floods. - **Challenges:** Exposure to fierce desert winds leads to high silt accumulation (*Ghad*) and evaporative losses of up to 50% of stored volume during summer, requiring annual collective desiltation drives (*Ghad Kadhna*) by the village community.

3. Agricultural, Watershed & Hill Water Structures

3.1 Khadin (Khadeen)

The Khadin system represents an internationally lauded fusion of rainwater harvesting and drought-resilient arid agriculture.

                               Next Khadin Basin or Stream

Historical Genesis:

- Developed in the **15th century** by the agrarian **Paliwal Brahmins of Jaisalmer**. - Through this system, the Paliwals transformed the most hyper-arid tract of India into a thriving agrarian granary capable of yielding bumper winter crops even during severe drought cycles.

Structural Mechanics & Agro-Ecological Cycle:

1. **Catchment-to-Bed Ratio:** Constructed in broad valleys flanked on two or three sides by gravelly rocky ridges. The catchment to agricultural bed ratio averages **15:1**. 2. **Dhora (धोरा):** A massive, well-compacted earthen embankment (3 to 6 metres high) raised across the lowest drainage outlet of the valley. 3. **Moisture Saturation & Siltation:** During the brief monsoon showers, runoff from the rocky ridges submerges the Khadin bed under 2 to 4 feet of water for several weeks. During this standing period: - Fine, nutrient-laden colloidal silt settles onto the soil. - Water deep-percolates, thoroughly saturating the subsoil profile. - Soil salinity is flushed downwards (*Leached*) into the deeper ground. 4. **Khadia (खड़िया):** Stone-masonry spillways and sluice gates installed at the embankment flanks to release excess floodwaters into downstream Khadins. 5. **Rabi Harvest without Irrigation:** By October, water either evaporates or is drained away. Farmers immediately sow cold-weather winter crops—predominantly **Gram (चना), Wheat (गेहूं), and Mustard (सरसों)**—which mature entirely on stored residual subsoil moisture without requiring a single cycle of artificial irrigation.

3.2 Johad

A Johad is an indigenous, crescent-shaped earthen check dam constructed across ephemeral drainage nullahs in the semi-arid terrains of **Shekhawati (Sikar, Jhunjhunu, Churu)** and eastern Rajasthan (**Alwar, Bharatpur, Jaipur**).

Primary Function: Aquifer Recharge

- Unlike a tank designed purely for immediate surface draw, the principal objective of a Johad is **slow, continuous groundwater recharge**. - By capturing flash-flood runoff behind permeable silt beds, Johads elevate water tables across surrounding wells and stepwells for several kilometers downstream.

The Johad Renaissance: Rajendra Singh and Tarun Bharat Sangh (TBS)

- By the early 1980s, commercial mining, deforestation, and rampant deep tubewell drilling had devastated the Aravalli foothills in Alwar, transforming it into an official 'Dark Zone' where all rivers had dried up. - **Rajendra Singh ('Waterman of India')** mobilized indigenous wisdom through his organization **Tarun Bharat Sangh (TBS)**, spearheading the construction of over **8,600 community Johads**. - **River Revival:** The cumulative infiltration from these Johads replenished dry underground aquifers, miraculously reviving five dead seasonal rivers into perennial flows: 1. **Arvari River (अरवरी नदी)** 2. **Ruparel River (रूपारेल नदी)** 3. **Sarsa River (सरसा नदी)** 4. **Bhagani River (भगानी नदी)** 5. **Jahajwali River (जहाजवाली नदी)** - **The Arvari Parliament (1999):** In 1999, 72 riparian villages along the revived Arvari basin formed India's first participatory river parliament to democratically regulate water usage, ban commercial borewells, and manage fish habitats. - **Honours:** Rajendra Singh was conferred the **Ramon Magsaysay Award in 2001** and the **Stockholm Water Prize (the 'Nobel Prize for Water') in 2015**.

3.3 Bawari (Stepwells)

Stepwells represent the zenith of India's architectural aesthetics harmonized with practical water engineering.

Classical Classification of Stepwells (Vastu Shastra):

Ancient architectural treatises—**Aparajitaprichha** and **Manasara**—classify stepwells into four sacred categories based on entrance apertures and subterranean tiers:
Stepwell Type Entrance Apertures Subterranean Storeys / Pavilions Architectural Profile
1. Nanda (नंदा) 1 (Single entry) 3 tiers Simplest single-stepped corridor.
2. Bhadra (भद्रा) 2 (Opposing entries) 6 tiers Stepped corridors descending from two opposing sides.
3. Jaya (जया) 3 (Triple entries) 9 tiers Magnificent structure with entrances from three cardinal directions.
4. Sarvatobhadra / Vijaya 4 (Four entries) 12 tiers Ultimate subterranean palace; stepped flights descending from all four directions.

Famous Historic Stepwells of Rajasthan:

Name of Stepwell Location (District) Patron & Period Distinguishing Architectural / Historical Trait
Raniji Ki Baori Bundi Rani Nathavati (1699 AD, queen of Rao Raja Aniruddha Singh) Bundi is universally known as the "City of Stepwells". Celebrated for exquisitely carved Torana gates, serpentine brackets, and a 300-ft-deep stepped flight.
Chand Baori Abhaneri (Dausa) King Nikumbha / Chanda (8th–9th Century AD, Pratihara Era) India's deepest and most visually stunning stepwell; 13 storeys deep, ~100 ft vertical drop, geometrically mesmerizing maze of 3,500 narrow steps.

3.4 Jhalra

A Jhalra is an architecturally ornate stepped tank distinct in origin and socio-cultural function from a Bawari.

Distinguishing Characteristics:

1. **Absence of Independent Catchment:** A Jhalra has no natural groundwater spring or overland catchment. 2. **Seepage-Fed (Percolation):** It is always situated downstream of an elevated lake, tank, or dam, fed exclusively by **subsurface seepage (Percolation)** through rocky fissures. 3. **Prohibition as Drinking Water:** The water of a Jhalra is **strictly prohibited from human consumption**. It is reserved solely for ritual ablutions, temple ceremonies, caste purifications, and washing. 4. **Jodhpur's Masterpieces:** - **Toorji Ka Jhalra:** Commissioned in the 1740s by Queen Tanwarji (Toorji), consort of Maharaja Abhay Singh. Carved from local rose-red sandstone featuring dynamic relief carvings of dancing elephants, lions, and water deities. - **Mahila Bagh Jhalra:** Fed by seepage from Gulab Sagar Lake in Jodhpur.

3.5 Interlinked Lakes & Reservoirs (Talab, Sagar, Sarovar)

Feudal rulers in Rajasthan designed sophisticated **cascading lake systems**, engineering natural contours to prevent flash floods and maintain city-wide water security.
  • Udaipur's Cascading Chain: Built from the 16th to 19th centuries by the Maharanas of Mewar. Lake Pichola, Amar Kund, Rang Sagar, Swaroop Sagar, Fateh Sagar, and Badi Lake are interconnected via masonry canals and overflow gates. Surplus overflows cascade sequentially into lower basins without spilling into residential streets.
  • Historic Landmarks:
    • Rajsamand Lake (Kankroli): Excavated across the Gomati River between 1662 and 1676 AD by Maharana Raj Singh as a colossal famine relief work. Its northern embankment (Nau Chowki Paal) features 25 black marble slabs inscribing the Raj Prashasti in 1,917 Sanskrit verses—India's longest stone inscription.
    • Jaysamand Lake (Dhebar Lake - Salumber): Constructed 1685–1691 AD by Maharana Jai Singh across the Gomati River. Asia's second-largest artificial freshwater lake (surface area ~87 sq. km) containing 7 inhabited islands (the largest being 'Baba Ka Magra' and the smallest 'Pyari').
    • Gadisir / Ghadsisar Lake (Jaisalmer): Excavated in 1367 AD by Rawal Ghadsi Singh, encircled by ornate domed chhatris, shrines, and the iconic Tilon Ki Pol gate.
    • Ana Sagar (Ajmer): Built in 1137 AD by Chauhan ruler Arnoraja (Anaaji) across the Chandra River. Later embellished by Mughal Emperor Jahangir (Daulat Bagh) and Shah Jahan (marble Baradaris).

4. Modern Rainwater Harvesting, Watershed Science & Hydro-Geology

4.1 Rooftop Rainwater Harvesting (RWH)

Rapid urban concretization prevents natural groundwater recharge, mandating engineered Rooftop RWH.

Statutory Mandate in Rajasthan:

Under the **Rajasthan Municipal (Urban Land Disposal and Building) Regulations**, the installation of a functional Rooftop Rainwater Harvesting structure is **legally mandatory for all new residential, commercial, and institutional plots measuring 300 square metres or larger**. Building completion certificates are withheld in the event of non-compliance.

Key System Components:

1. **Catchment:** Terraced, paved roof surface. 2. **First-Flush Device:** A valve system that diverts the initial 15–20 minutes of monsoon rain carrying accumulated dust, bird droppings, and atmospheric pollutants away from storage tanks. 3. **Composite Filter Unit:** - Top layer: Fine washed sand (40 cm) - Middle layer: Graded gravel (20 cm) - Bottom layer: Rounded boulders (20 cm) - Activated charcoal bed: To adsorb dissolved organic compounds and eliminate odour. 4. **Recharge Pit vs. Sump:** Treated water is either routed into an underground masonry cistern for direct domestic drinking usage or injected via a recharge bore directly into the local aquifer.

4.2 Watershed Management & The 'Ridge-to-Valley' Principle

A watershed is an integrated geographical drainage basin where all precipitation converges into a single common stream or depression.

'Ridge-to-Valley' Sequence:

Scientific soil and water conservation requires that treatments begin at the topmost ridge line and progress down to the valley floor: 1. **Continuous Contour Trenches (CCT):** Trenches excavated along equal contour elevations across steep hill slopes to decelerate runoff velocity, halt soil erosion, and promote deep infiltration. 2. **Loose Boulder Check Dams (LBCD):** Dry-stone barriers placed across high-gradient gullies on the upper ridge to trap sediment. 3. **Gabion Structures:** Heavy-duty hexagonal galvanized iron wire mesh boxes filled with quarry stones laid across intermediate drainage channels. They cushion flood velocity while allowing clear water to percolate. 4. **Masonry Anicuts:** Low-height (1 to 2 metre) permanent masonry weirs constructed on lower valley streams to impound surface water and recharge village tubewells. 5. **Farm Ponds (Khet Talai):** Excavated retention ponds dug in the lowest corner of individual farmlands, heavily subsidized by the State Government (60% to 70% capital subsidy).

4.3 Central Ground Water Board (CGWB) Categorization & Dark Zones

The **Central Ground Water Board (CGWB)** and the Rajasthan State Ground Water Department classify assessment units (blocks) based on the **Stage of Groundwater Extraction (SOE)**:

$$ ext{SOE (%)} = \left( rac{ ext{Annual Gross Groundwater Draft}}{ ext{Annual Extractable Groundwater Recharge}} ight) imes 100$$

Assessment Category Stage of Groundwater Extraction (SOE) Hydrogeological Condition
Safe (सुरक्षित) $< 70%$ Groundwater draft is well within natural annual replenishment.
Semi-Critical (अर्ध-नाजुक) $70% ext{ to } 90%$ Significant stress; withdrawal approaching recharge capacity.
Critical (नाजुक) $90% ext{ to } 100%$ Severe stress; emergency conservation mandatory.
Over-Exploited / Dark Zone (अति-दोहित) $> 100%$ Catastrophic deficit; abstraction exceeds recharge, causing falling water tables.
Saline (लवणीय) N/A Naturally mineralized aquifers unfit for domestic/irrigation use.

Groundwater Crisis in Rajasthan:

- Out of **302 assessment blocks**, over **219 blocks** are categorized as **Over-Exploited (Dark Zones)**. - The state's aggregate groundwater extraction rate exceeds **150%**, triggering precipitous water table declines of 1 to 3 metres annually across Jaipur, Dausa, Alwar, Sikar, and Jodhpur, alongside dangerous increases in fluoride and uranium toxicity.

6. Cultural Traditions, Sacred Ecology & Water Movements

6.1 Sacred Ecology: Orans and Gauchars

- **Oran (ओरण):** Sacred community groves consecrated to folk deities (e.g., Ramdevji, Gogaji, Pabuji, Tejaji, Karni Mata). Cutting timber or polluting within an Oran is culturally forbidden. - Hydrologically, an Oran serves as the pristine, unpolluted **surface catchment** for the village Nadi or pond, preserving vegetation and filtering silt. - **Gauchar (गोचर):** Designated common grazing pastures that retard surface runoff and facilitate diffuse groundwater percolation.

6.2 The Arvari River Restoration & Waterman Rajendra Singh

- **Tarun Bharat Sangh (TBS):** Grassroots movement founded in 1975, headquartered at Bheekampura, Alwar. - **The Miracle of Arvari:** The 45-km-long ephemeral Arvari River had dried up into a barren dust course by the 1980s. Through the indigenous construction of hundreds of interconnected Johads and earthen dams, the groundwater table rose dramatically, reviving the river into a perennial stream by the mid-1990s. - **Jal Biradari:** A nationwide coalition of river basins and water stewards established to advocate decentralized river basin conservation over mega-dam interlinking.
