- Energy-Passive Groundwater Recharge System (EGRP)

0

The Parjana EGRP system is a patented break through innovation that manages surface and    underground water in an eco-friendly and sustainable way. The EGRP system is installed under-ground and after its period of acclimation, distributes water evenly and horizontally by reactivating    all the microlayers along the entire length of each EGRP. It indirectly influences water infiltration during rainfall and provides moisture during dry moments, thus creating an equilibrium point. The EGRP dramatically increases the rate of infiltration, enhancing natural conditions and improving areas where infrastructure has created impervious areas. The EGRP helps rebalance groundwater conditions by establishing new ways water can move to, and through, the soil. The EGRP® enhances infiltration by moving water more effectively and efficiently through the soil matrix and into the water table.

Each EGRP has a central core with four crescents around the central core. EGRP®s are made of polyethylene plastic and are chemically inert so as not to degrade in the soil. The EGRP® has a smooth surface restricting silting and or clogging.  Each EGRP is capped. The cap closes the system so as not to act as a conduit for water free flow.  The EGRP®s are placed either the fully or partially in the vadose zone two to three feet below the surface in lengths of 5’ (1.524m), 10’ (3.048 m), 20’ (6.096 m) and 40’ (12.192 m).  The EGRP® is 1 ¼” (31.75 mm) in diameter.

The EGRP works by providing a path that allows water to move faster. The EGRP channels, in close association with soil particles enhance up and down movement as well as movement into and out of the surrounding soils. Natural forces work toward water balance between wet and dry areas. The illustrations show the general operation. After installation the EGRP provides a new connection between surface soils and deeper soil environments. The cap prevents direct channeling of water to the EGRP and also serves to equalize forces as water is moved.

Promotes infiltration

The EGRP® increases infiltration by establishing a connection between the surface and soil and rebalances the hydrologic cycle that was disrupted by impervious surfaces.

Promotes drainage

The EGRP® reduces stress on overburdened stormwater drainage systems by mitigating stormwater runoff and removing excess rain and groundwater from the surface.

Facilitates the movement of water

The EGRP® facilitates the movement of water from the surface by providing a path for water molecules to move vertically along the EGRP® and therefore, eliminating water accumulation.

Manages water

The EGRP® helps rebalance groundwater conditions by establishing new ways water can move to, and through, the soil. The EGRP® also enhances the balance between wet and dry areas and distributes water in greater volumes of soil.

Improves moisture content

The EGRP® equalizes soil moisture content by establishing a connection between the surface and soil. It also nourishes the root system by bringing moisture towards the surface during dry seasons.

Recharges groundwater

Groundwater recharge is a hydrologic process where water moves downward from surface water to groundwater. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Through the facilitation of water movement and infiltration of water, the EGRP® provides more water volume underground.

Step 1: Site Analysis and Layout Design
Every site is specific to the EGRP. Layouts are custom designed solutions that address the customer's water problems. The following variables
contribute to the design of the EGRP layout: area, impervious surfaces, vegetation, underground flow, precipitation, soil conditions/saturation, elevations and subsurface/surface obstructions.

Step 2: Installation
A hole, slightly larger in diameter than the EGRP® and at least 12' longer than the length of the EGRP®, is bore with a drilling machine to the appropriate depth in the vadose zone. The hole is then closed with the excavated soil.

Step 3: Maintenance Free System
Once installed, there is no maintenance necessary. Just let the system operate. The system will need to acclimate. This period will vary in length depending on rainfall, underground water saturation, temperature and elevation.
