The Ecosol GPT is designed specifically to provide essential primary treatment of stormwater runoff. It is an efficient, cost-effective solution to the ever-increasing problem of gross pollutants present in stormwater. Key to its success is the robust, engineered design and tangential screens housed in a pre-cast concrete pit that provides a significantly greater screening area than that of traditional direct screening trash rack designs. Further its large detention chamber enables gravitational separation to occur at low flow velocities retaining fine particulate matter conveyed in stormwater.
In 1997 and 1998 the Urban Water Resources Centre – University of South Australia (UniSA), was commissioned to undertake a series of tests on the widely-used Ecosol GPT (formerly known as the RSF 4000) to confirm the product’s performance. The tests measured the capture efficiency of the system under varying flow conditions and gradients and also the hydraulic headloss of the system under varying flows and gradients.
In October 1998 after further product development Ecosol commissioned Engtest the Department of Civil and Environmental Engineering at the University of Adelaide to undertake further testing on the system to confirm hydraulic headloss and capture efficiencies.
Concurrently Avocet Consulting was engaged to complete extensive CFD Modelling to determine Pollutant Trapping Performance and fluid hydraulic characteristics under varying flow conditions.
In early 2000 to mid-2001 as part of the company’s continuous product improvement program Ecosol engaged the services of Avocet Consulting to assess the Ecosol GPT‘s hydraulic performance, structural integrity, capture efficiency, treatable flow rates relevant to product sizing and scaling. Additional laboratory testing was also completed to monitor its performance as it filled and also to review the non-blocking, tangential filtration longevity of the system under varying flow conditions and percentage of fill.
Finally in 2013 EngTest Department of Civil and Environmental Engineering – University of Adelaide completed a series of additional product tests to further verify product performance and concurrently reviewed all past laboratory and field testing on the performance of the product to comprehensively determine its performance for current industry applications.
