In 1999 breakthrough technology identified as the EPIC™ system turned the world of irrigation upside down. Using a sand based rootzone, capillary physics for vertical water distribution and gravity for horizontal and drainage distribution, the passive system achieved 100% efficiency in irrigation, better turf quality and affordable low maintenance and construction.
Direct comparative studies demonstrated 58% less water needs as compared to sprinklers, and overnight the 2/3 water allocation in outdoor use for desert climates could be reduced significantly without a change in landscape area, plant species or cultural habits. Water needs can be reduced by up to 70% when installations include storage tanks.
In EPIC™ designs the use of low fertility sands, large particle sizes, and flat non-erosive terrain also means that nutrients that are available in the growing media do not move offsite.
The non-pressurized system allow to achieve irrigation with a number of water sources without any public health concerns. Domestic water, shower water reuse, and reclaimed water from sewage treatment plants could all be blended and be reused even in residential settings without any public health issues. However easier and more importantly, the EPIC™ system opened the doors for efficient capture and reuse of storm water directly. The system acts as a pre‐filter for runoff sources prior to storage and then as an efficient irrigation system during dry periods.
Erosion Control, Drainage & LID
Water management of record rainfall events. Combine passive sand filtration treatment, integral water storage of 2.5 gallons per square foot, stored water reuse through sub-irrigation and a drainage pipe that cannot plug and you have the world’s best water management system to address erosion and drainage issues.
An inch of rain over a one square foot surface produces 0.62 gallons of essentially pure distilled water. Yet culturally and from a civil engineering perspective the traditional ingrained philosophy is that storm water is a waste product that must be removed and shed from the property as quickly as possible. The philosophy evolved to elaborate systems that move water away from developed property. EPIC™ systems opened the doors for efficient capture, passive treatment and reuse of storm water directly. The system acts as a pre-filter for run-off prior to storage and then flips as a 100% efficient irrigation system during dry periods. EPIC™ systems are true water management of a valuable resource.
Parks & Athletic Fields
Multifunctional parks and fields create opportunities beyond traditional turfgrass recreation and beautiful landscaping. EPIC™ systems enable parks and fields to function as a stormwater treatment system, with irrigation needs reduced to 50-85% less water than traditional top-down systems. Collaboration with EPIC™ enables parks and athletic fields to save costs in water use, eliminate single –serving land uses, decrease gray infrastructure and provide added value in all green spaces. EPIC™ systems provide a non-pressurized, gravity driven irrigation and exceptional drainage system that has no moving parts, no surface emitters or drip lines to vandalize or damage.
Green landscaping around homes not only improves aesthetics and home values, but actually reduces the ambient temperature in the home envelope by better than 10 degrees. While conventional trends dictate xeriscape landscaping for perceived water savings, EPIC™ systems can actually provide lush landscapes with even less potable water use. All landscaping irrigation needs in EPIC™ systems for sub-divisions or individual lots can actually be accomplished through storm water capture and retention techniques and even supplemental reuse of shower water without public health issues or concerns.
Whether you are building a green or perfectly level tee boxes that are never sprinklered from above, or in need of drainage pipe that never plugs your bunkers or low lying areas then EPIC™ is a must. The unique and proven drainage and irrigation properties of EPIC™ technology will become the eventual standard in Golf construction once the technology becomes more widely known and tried with an expanding consumer base. The simplicity of design, the reliance on gravity and capillary physics as the operating forces, and cost savings in installation and subsequent maintenance will make EPIC™ the product of choice by architects, owners, and superintendents.
The EPIC™ system has the versatility to grow any plant on a green roof, not just succulents. The total weight at saturation is 120 lbs per square foot plus the weight of vegetation and trees. The green roof can act as your storm water management and offset ambient temperature reflection caused by the urban heat island effect.
The EPIC™ system is an advanced form of Sand Hydroponics. Publicly introduced in 1999, it is a scientific breakthrough in how plants are grown, watered and provided with nutrients. In large scale installations throughout the world, especially in desert climates, sustainable projects from landscaping, sports fields, and in agriculture the system showed reduced water usage by 50-80% when compared to drip or sprinkler systems, used less fertilizers yet produced a larger quantity and better plant quality. Watering frequency is also reduced to once per week watering in desert environments when temperatures exceed 90°F.
The unique and proven properties of EPIC™ technology will become the eventual new standard in Leach Line Construction as the technology becomes more widely known by Health Department Regulators and tried with an expanding consumer base. The simplicity of design, the reliance on gravity and capillary physics as the operating forces, and cost savings in installation and subsequent maintenance will make EPIC™ the product of choice by design engineers, owners, and installers.
