Abstract
An apparatus and method for monitoring sanitary sewer systems designed to carry away wastewater through a system of buried pipes, often referred to as “sewer lines”, to a sewage treatment facility, the apparatus and method use a weir which facilitates the collection of flow rate data in the sewer lines which in turn facilitates the determination of infiltration and inflow (“I/I”) of rain water, or clear water, into the sewer system in a manner which further allows the identification of specific I/I locations so that repair and construction of sewer systems can be efficiently coordinated.
Claims17
A method of measuring flow characteristics in a sewer pipe, comprising:
- providing a micromonitoring apparatus in a sewer pipe at a measuring location, the micromonitoring apparatus comprising:
- a weir that includes a low point having a height and one or more and lateral portions that lie lateral to the low point and that are higher than the height, the weir preventing wastewater that lies below the low point from passing downstream in the sewer pipe;
- a ramp having an upstream portion that conforms to an interior of the sewer pipe, the ramp extending downstream from the upstream portion to the low point of the weir and shaped to direct at least portions of the flow of wastewater toward and over the low point of the weir;
- and
- a sensing probe;
- inserting the micromonitoring apparatus into the sewer pipe;
- measuring flow characteristics with the sensing probe, wherein measuring flow characteristics includes measuring flow characteristics of wastewater within the sewer pipe;
- and
- recording the measurements of the wastewater characteristics.
