Local term: वर्षा जल संचयन — ईशान्य (Varṣā Jala Saṁcayana — Īśānya)
Modern CGWB and municipal mandates align with NE harvesting — the natural SW-to-NE compound slope directs all surface runoff to the NE. Underground sumps at the NE minimize pumping costs (gravity-fed). Recharge wells improve groundwater levels. The Chennai model (India's most successful) validates NE collection.

Unique: NE gravity-fed collection minimises pumping costs — distinctive to Modern Vastu practice per the contemporary Vastu consensus synthesizing classical prescriptions.

The Rule in Modern Vastu
Ideal
NE, NNE, ENE
NE underground sump with gravity-fed roof collection, per modern Vastu consensus integrating classical prescriptions with contemporary building practice — the architect must verify compliance for optimal results.
Acceptable
N, E
Placement in adjacent East or North zone is acceptable when Northeast is not feasible, with evidence-based spatial correction as compensating measure.
Prohibited
SW, SE
SW waterlogging; SE fire-water conflict.
Sub-Rules
- Rainwater harvesting sump is in the NE zone▲ Moderate
- Harvesting sump is underground (preserving NE openness)▲ Minor
- Recharge well is in the NE (water returning to earth in water zone)▲ Minor
- Rainwater harvesting in SW or SE▼ Moderate
Rainwater harvesting belongs in the NE — Soma's water-element zone naturally collects rain at the compound's lowest point. Underground sump preserves NE openness. SW harvesting waterloggs the earth zone; SE harvesting creates fire-water conflict.
Common Violations
Rainwater harvesting in SW — waterlogging the earth zone
Traditional consequence: Standing water in the SW waterloggs the earth-element zone — foundations weaken, the compound's grounding energy becomes unstable, and the SW's natural density is compromised by water intrusion.
Rainwater harvesting in SE — water in fire zone
Traditional consequence: Water collection in the fire zone creates elemental conflict — fire-element equipment near the harvesting sump experiences corrosion and humidity. The stored water absorbs fire energy and becomes energetically impure.
How Other Traditions Compare
Relative to Modern Vastu
Soma's water-gift collected at NE — distinctive to Vedic practice per the Brihat Samhita and Vishwakarma Prakash.
Paus Pani Sangraha at NE — this reflects the Hemadpanthi tradition where the Samarangana Sutradhara and Hemadpanthi building traditions govern factory layout, manufacturing zone organization, and industrial facility planning.
Chennai mandate aligns with NE pada placement — distinctive to Agama Sthapati practice per the Mayamatam and Kamika Agama.
Varsham Neeru at Ishanyam — this reflects the Kakatiya tradition where the Samarangana Sutradhara and Kakatiya inscriptions govern factory layout, manufacturing zone organization, and industrial facility planning.
Water conservation as environmental Ahimsa — distinctive to Hoysala-Jain practice per the Manasara and Aparajitapriccha.
Large NE capacity for Kerala's heavy rainfall — distinctive to Thachu Shastra practice per the Thachu Shastra and Manushyalaya Chandrika.
Critical NE harvesting for semi-arid climate — distinctive to Haveli-Jain practice per the Vishwakarma Prakash and Jain Vastu texts.
Natural NE slope supports collection — distinctive to Vishwakarma practice per the Shilpa Prakasha and Vishwakarma guild traditions.
Coastal rain collection at NE — this reflects the Kalinga tradition where the Shilpa Prakasha and Kalinga temple texts govern factory layout, manufacturing zone organization, and industrial facility planning.
Water conservation for Langar Seva — distinctive to Sikh-Vedic practice per the Vedic Vastu principles adapted through Sikh architectural traditions.

Remedies & Solutions
Industrial facility correction per Modern manufacturing layout
Modern VastuInstall an underground rainwater harvesting sump in the NE zone with rooftop collection gutters directing water to the NE. Include sand-gravel filtration before the sump.
If the harvesting sump is not in the NE, install a recharge well in the NE that receives overflow from the existing sump — at least some water returns to earth in the water zone.
Ensure all surface drainage channels converge toward the NE before entering the harvesting sump — even if the sump is elsewhere, the water flow path passes through the NE zone.

HemadpanthiClassical Sources
“The vessel that collects Varuna's rain — the Megha-Jala-Sangraha — shall be in the Ishanya, where water naturally gathers at the lowest point of the compound. Soma's quarter receives and purifies rain, and the underground sump stores it for dry-season use.”
“The Varsha-Jala-Kosha (rain-water reservoir) shall be at the Ishanya pada — where the compound's slope naturally directs all surface water. The underground tank preserves Ishanya's openness while collecting Soma's precious water gift.”
“Rain falling upon the compound gathers at the NE — the lowest, purest point. An underground vessel at the NE stores this divine water without disrupting the zone's sacred openness. This stored rain becomes the compound's reserve of purified Soma-water.”
“Vishvakarma collected celestial rain at the NE of the divine compound — where Soma purified each droplet and stored it underground for the dry cosmic season. This is the template for all earthly water harvesting — NE collection in underground vessels.”
