About IRIS
™
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. IRIS™ implementation consists of multiple devices that are installed vertically into the ground and arranged within a carefully calculated layout.
IRIS™ improve infiltration rates without disturbing ecological balance, as the devices do not encourage water to flow straight down to the bottom of the device like a pipe. They enhance horizontal distribution of water through the soil matrix, as well as vertical distribution. At Parjana℠ Engineering, we provide engineered water management solutions for various applications: residential, agricultural, commercial, and municipal. Parjana℠‘s experienced team of engineers, environmental specialists, and sales representatives deliver substantial, measurable benefits to our customers. While the objectives of every project are unique, below we summarize some of the benefits customers can expect from our professionally engineered solutions.
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.

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.

Cost-Effective, Sustainable Stormwater Management
IRIS™-based solutions can drain waterlogged surface soils, eliminate standing water, and reduce runoff into municipal sewer drain systems, which can significantly alleviate costs associated with stormwater treatment and minimize the introduction of undesirable pollutants into our traditional stormwater systems.
Healthy Soils
Enhanced infiltration of water provided by IRIS™-based solutions increases plant-available water content, which can lead to natural improvements in soil productivity and reduce the amount of water maintenance needed to keep lawns and agricultural crops healthy.
Pollution Runoff Control
Groundwater Recharge
Emulating the natural processes of aquifer recharge, IRIS™-based solutions merge ecology with technology to increase long-term rates of groundwater recharge by capturing and reclaiming stormwater and surface water generated in the built environment and directing it to permeate back into the natural groundwater system.

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%.
Groundwater Recharge
Reduces Runoff
Stabilize Soil Moisture Content
Parjana℠ IRIS™ system improves infiltration by creating a balanced environment. Data shows that moisture content is kept at its lower energy state, which is excellent for soil health and plant growth.
Maintenance Free
Low Impact Design
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.

Important to know about design and cost:
Each project is custom made. Even neighboring properties will have different aspects that will influence design.
IRIS™ never stop working, but there is a matter of time. Adding devices to a project can make the project more expensive, but it will also make the system work faster. TIME is a very important element of the design.
Area is another important element of design. The devices need to be installed underground making available area for installation a critical aspect to determine “system capacity”.
Environmental Evaluation
Prior to any design, each site undergoes a qualifying environmental assessment to ensure that the system will not directly interfere with sites of environmental contamination and are within regulation-based authorized areas. After carefully considering geohydrology, Parjana℠ can offer solutions that make the best use of the land’s geography, designing systems that require low intervention and minimal ecological disturbance.
Comprehensive approach
Customer Centered Approach
Every customer and project is different and the needs of the customer are our number one priority. The scope of the design is formed on the basis of understanding the timeline and infiltration goals of the customer. Parjana℠ Engineering then combines that information with all topographic, geohydrologic, and geotechnical data to develop the best solution available.
Installation Information:
System installation is performed by a certified installer. Immediately prior to installation, all utilities and hazards will be properly identified and any necessary updates to the design will be made.
