Benefits Dossier

EPIC is a sealed subsurface cell of polypropylene chambers on an EPDM liner, buried in qualified sand, and the dossier sets out each benefit that follows from that arrangement: first the mechanism, then the number the mechanism produced in service, then the meter, letter, trial or study that number comes from.

Every figure carries one of three marks. Verified figures were measured in the record: field installations, metered trials, monitored government pilots, signed client letters, university studies and laboratory analysis. Directional figures are engineered but not yet proven at project scale. Reference material is background from the wider literature and is never presented as EPIC performance. A register of applications separates what has two decades of service behind it from what has been measured once and what is still at prototype stage.

Part 1 states the case on a page. Parts 2 to 5 group the benefits by mechanism: water, agronomy and soil, operations and asset life, and environment and compliance. The Gulf record covers named, dated sites in the UAE and Saudi Arabia, each monitored by a party other than EPIC, from the Al Dahra greenhouse trial in Al Ain to the Royal Commission pilot at Jubail, with the Sa'ad Park programme reported as under way.

Part 6 condenses the case for eight sectors: agriculture and horticulture, golf and sports turf, municipal landscape, residential development, septic and decentralised wastewater, mining, industrial and commercial stormwater, and green roofs and podiums. Part 7 is the evidence: the specification as built, the performance as measured, and a source index.
