BMS Design Details: The Mater Hospital is one of the largest hospitals in Ireland. FIMA Developments were the main Groundworks Contractor on the project for the main contractor, John Sisk and Sons Ltd. The BMS Ecostorm Defender Vortex Silt/Oil Seperator proved an ideal solution for the project to remove any oil/silt before the surface water flowed into an existing on site attenuation system. BMS unsurpassed ability to custom manufacture large tankage allowed the design and manufacture of a very large vortex silt/oil seperator for flows of up to 250 l/s. The 250 l/s Ecostorm involved transport in the early hours of the morning as an oversized load with an escort. The Ecostorm Defender is part of BMS surface water ‘one stop shop’ where BMS can offer all products including attenuation in the form of its world leading Stormbreaker, Drainmax infiltration tunnels, Petrol/Oil interceptors, Holding Tanks, Rainwater Harvesting Tanks and Filters and Hydrobrakescustom designed and delivered to site. Indeed, BMS can offer a full surface water attenuation installation service. Highlighting BMS ‘one stop shop’, BMS also supplied a small full retention interceptor, a hydrobrake and a non return valve for fitting alongside the Ecostorm.

Construction/Installation Details: BMS designed, manufactured and delivered all of the above.
The Ecostorm Defender is very easy to maintain. Depending on the flow and pollutant loading on site the containment chamber of the Ecostorm weather can be cleaned by suction tanker by an appropriately licensed contractor. The easy access sediment and floatable containment chambers should be monitored periodically for pollutant loading. Similarly any silt and oil in a BMS Full Retention Interceptor can be removed by suction tanker.
Vortex Silt/Oil Seperator: A hydrodynamic vortex seperator system designed to seperate grit/floating pollutants, oil, debris and contaminated settling solids from Stormwater. They are usually used up stream of attenuation/holding ponds as a means of pollutant removal. Full details of how a Vortex Silt/Oil Seperator like the BMS Ecostorm Defender functions can be found on the Ecostorm Page.
