SBIR Information Session, May 2017 - Gully Monitoring SBIR

  1. 1. SMALL BUSINESS INNOVATION RESEARCH GULLY MONITORING. Roy O’Donnell. Gully Manager. Surface Water and Flood Management Division.
  2. 2. SURFACE WATER AND FLOOD MANAGEMENT DIVISION. I am the Gully Manager of the Road Drainage Maintenance Unit (RDMU) which is part of the Surface Water and Flood Management Division and has the responsibility for carrying out the following duties:  Cleaning of 55,500 gullies within DCC’s functional area.  Cleaning of gully pipelines using high pressure jetting units.  Carrying out CCTV camera surveys of main sewers and all gully pipelines pressure cleaned.  Monitoring Flood Zones / Priority List / Extra Attention Lists.  Responding to flood emergencies.
  3. 3. PROBLEM STATEMENT  Low cost innovative solutions that can monitor and predict blocked / overflowing gullies in high risk flooding areas of Dublin (when a gully fills with water and overflows).  What does this mean?????  Blocked Gullies – when they no longer function removing the water from the road surface.  Overflowing Gullies – when the water is rising from within the gully due to capacity issues within the drainage network.
  4. 4. WHAT PROBLEMS DO WE FACE?  Pluvial Flooding - Pluvial flooding can be defined as flooding that results from rainfall-generated overland flow, before the runoff enters any watercourse or sewer.  Fluvial Flooding - Fluvial, or riverine flooding, occurs when excessive rainfall over an extended period of time causes a river to exceed its capacity.
  5. 5. WHAT PROBLEMS DO YOU FACE?  Different types of gullies – two fundamental types : 1. Sealed gullies on combined system. 2. Pit gullies on surface lines or draining to nearest rivers.
  6. 6. TWO TYPES OF GULLIES……. Water Level to here. Sealed Gully for combined sewer. Pit Gully for surface water sewer.
  7. 7. There are 26 listed types of gully grids / access points for draining surface water. How / where will the monitor be mounted?
  8. 8.  Ability to clean the gully after mounting of the monitor.  Ability for monitor to operate under water or within debris. Custom shaped shovel. Boom from Gully Machine. Large Heavy Crowbar
  9. 9. LOCATIONS FOR MONITORS  Roll out in known hotspots in city based on Local Knowledge and using Priority List gullies.  Monitors wont be needed in all 55,500 gullies but would hope for 10-50 monitors in specific vulnerable locations.  Gullies they are mounted in will be maintained very regularly.  Time needed to wait for a flood event to occur to test system....
