front end loader after the water has receded some. Those are very rare events but anywhere there <br /> are deep canyons in mountainous country such floods are always a possibility. Losing a pump in <br /> such a flood would simply make things worse as such a pump would probably have a gasoline <br /> engine - fuel and oil would then further contaminate Turkey Creek. <br /> The outlet hose from the pump is then placed in the drainageway downstream from the <br /> "wall"holding back the sediment basin. The water from that hose is then directed into a filter sock <br /> which removes most of the sediment that is incidentally pumped out with the water. <br /> This water then flows down this drainageway a short distance to Turkey Creek An <br /> additional filter in the form of a silt fence at the toe of the drainage can remove any sediment <br /> picked up between the filter sock and the stream. The silt fence will be well anchored in the bed of <br /> the drainage so pond water discharge doesn't just flow under the fence and into the stream. <br /> This system should be very effective in discharging cleaner water. And it can very likely be <br /> operated by one person with minimal help from heavy equipment. All the person really needs to do <br /> is monitor the clarity of the water going into Turkey Creek and watch for leakage of the pond <br /> water from the discharge circuit that could reach the creek <br /> A refinement that could be included is to have the entrance to the intake hose elevated <br /> some so only the cleaner water above the sediment layer is removed and the much dirtier water <br /> next to the sediment layer cannot be accessed. This would also avoid pumping out mud. The hose <br /> could be on a float to keep the intake a bit higher than the sediment layer. <br /> METHOD 2: (This is an alternate method in the event Method 1 cannot be used due to a <br /> particular circumstance. It is not expected this method will ever be used, but it is included to <br /> provide a backup approach.) <br /> This approach is the simplest and uses the water truck as a vehicle for moving the pond <br /> water to Turkey Creek Water in the pond is withdrawn by pumping into the water truck. Then the <br /> water truck is driven to a location where it is out of the way of traffic and the water is drained <br /> from the tank into Turkey Creek To remove the sediment in the pond water the water drained <br /> from the water truck is passed through a filter sock on the outlet hose from the tank The sock <br /> Technical Revision Menzer Quarry M-1973-009-HR June 2021 Page 6 of 7 <br />
