Our Mission
At Parjana℠ Engineering, we are dedicated to providing water management and consulting services that are innovative, integrative, and data-driven.
Parjana℠ Engineering champions water conservation through innovative solutions that address the pressing global need to manage water resources efficiently.
Our Expertise
We provide engineered water management solutions for stormwater and groundwater challenges. Applications include: residential, agricultural, commercial, and municipal. Parjana’s℠ experienced team of engineers, environmental specialists, and sales representatives deliver substantial, measurable benefits to our customers.
Our Product
IRIS™ is a device designed to increase the infiltration of surface water into near-and-sub-surface soils, providing subsequent benefits to groundwater recharge, runoff mitigation, water quality, and vector control.
Who we serve
Municipalities & Utilities
Reduce runoff, support MS4 goals, and enhance existing basins with passive infiltration.
Data Centers
Turn campus stormwater into verified infiltration performance and auditable water data.
Solar Infrastructure
Cut standing water and erosion on utility-scale arrays while documenting site performance.
Commercial Properties
End flooding on lots, fields, and grounds with low-impact infiltration.
Our solutions
IRIS™ Infiltration
The passive device that increases infiltration into native soils. Zero energy, zero maintenance.
Existing Basin Enhancement
Boost infiltration and cut evaporation in basins already in service. No rebuild, no excavation.
Monitoring & MRV
Measure, verify, and report every gallon infiltrated for auditable, AI-ready water data.
How the system works
One path, from a hard surface to a verified gallon.

Innovative engineering solutions tailored for you
Verified Water Credits
Every gallon, on the ledger.
Parjana’s IRIS™ device captures stormwater at the surface and infiltrates it back into the soil — recharging groundwater, reducing runoff, and restoring the natural water cycle. Through our partnership with HydroCoin, every gallon IRIS infiltrates can now be quantified, independently verified, and tokenized as a water credit on the XRP Ledger.
The framework that makes this possible is MRV — Monitoring, Reporting, and Verification. Site sensors measure infiltration in real time, third-party validators verify the data, and each verified gallon is issued as one HydroCoin token. For municipalities, developers, and growers, that means an auditable, blockchain-anchored record of the stormwater your project diverts — and a credit-based pathway to fund the infrastructure that delivers it.
