Since 2012, Parjana℠ has manufactured and installed Parjana℠ system with incredible results for infiltrating stormwater and recharging groundwater. Over a decade of monitoring, testing, and data review have provided the knowledge to make significant improvements to this amazing technology.
In the summer of 2024, Parjana℠ Engineering proudly introduced IRIS™. This new product design increases system infiltration rates by 15%, reduces materials and waste, and speeds up installation time over the Parjana℠ system. These improvements not only enhance the performance of the system, but also decrease the carbon and ecological footprint making it an even more sustainable solution to water management problems.
IRIS™ uses the power of nature to connect soil layers and to enhance water movement between molecules. Like the Parjana℠ system, IRIS™ is still a zero energy, zero maintenance, zero visual solution that comes with a 10 year installation warranty and 25 year product warranty giving you the peace of mind that your water is being managed without needing additional time, effort, or funds for years to come.
As water security, water scarcity, extreme weather, and climate change affect how we manage this vital resource, Parjana℠ Engineering and IRIS™ system are leading the way to a water balanced future.

How It Works
Stormwater Infiltration and Volume Reduction
Excessive first-flush stormwater runoff can burden existing gray infrastructure, leading to high maintenance costs, contaminant transfer, and the risk of Combined Sewer Overflows (CSOs). IRIS™ system effectively reduces peak flow and can minimize stormwater runoff volume into municipal sewer systems by upwards of 83%.

Integrated Systems
IRIS™ can augment traditional stormwater practices by increasing the infiltration rate and management capacity of systems that capture peak volumes – such as ponds, swales, or other storage devices – or can be paired with filtration/biofiltration systems to improve the water quality of volumes being infiltrated. This integrated approach provides a “mix-and-match” design process that develops tailored solutions to capture stormwater runoff, store peak volume, absorb pollutants and/or increase infiltration rates over time.
Additionally, integrated systems are proven to significantly lower management and operations costs, as well as aid new or existing developments in meeting environmental regulations. This is achieved through the systems’ ability to reduce peak storm discharges and downstream flooding, reduce stormwater runoff pollutant loadings, and increase groundwater recharge volumes.
Technical Specifications
Each IRIS™ device resembles a snowflake in which six split-end arms extend from a central core, and each is topped with a cap at the end closest to the surface level. Base lengths: 5’ (1.524 m), 10’ (3.048 m), 20’ (6.096 m) & 40’ (12.192 m). Diameter: 1 ¼” (31.75 mm) and 2 ¼ ” (57.15 mm) Color: Natural Transparent Clear, Colorless Material: Polyethylene Material characteristics: Non-reactive with environment, abrasion resistance.
IRIS™ implementation consists of multiple devices that are installed vertically into the ground and arranged within a carefully calculated layout. IRIS™ installation machine is 4’-wide and 16’-tall (clearance) on continuous track treads for minimal ground disturbance and maximum site access. There is no excavation resulting in material removal from the ground, nor the necessity to add new material (soil) to the site making the entire process minimally invasive.
