Abstract: A funnel is operationally mountable on the downstream side of a weir positioned in a wastewater stream which contains oils, fats and/or grease. The funnel has a sample port near the discharge neck and tubing is connected to the funnel in communication with the sample port. The opposite end of the tubing is connected to a pump. Wastewater flowing over the weir flows into the funnel and is agitated and mixed. Operation of the pump causes a homogeneous and representative sample to be withdrawn from the stream.

Abstract: Apparatus and a method for monitoring the rate of flow of storm water in an individual sewer. The apparatus comprises a collector bowl mountable beneath the storm sewer manhole cover and positioned to collect all water entering through the manhole cover. A flow pipe is mounted in the bowl and projects upwardly from the bottom thereof. Water collected in the bowl must rise to a level above the flow pipe before it will flow through the pipe and into the sewer. A flow meter sensitive to the water height above the flow pipe is positioned in the bowl and measures and records the rate of flow.
