Although cleaning should be regarded as a routine Grand Rapids sewer repair and maintenance operation, it is often necessary to clean a sewer before it can be inspected or before rehabilitation can be carried out. Sediment, in the form of grit, loose bricks, rags, and general rubble, together with organic material, including grease and oil, is invariably deposited in sewers, and can build up over time, in some cases to form a complete blockage within the pipe. An additional impediment to the successful surveying and rehabilitation of sewers may be tree roots and laterals protruding into the sewer. These sediments and protrusions must be removed before rehabilitation takes place. There are a variety of methods used for cleaning sewers, the most common being some form of jetting, winching, or rodding. In addition there are now a number of proprietary methods for the remote cutting of tree roots and protruding laterals.

Hand excavation

The earliest form of sewer cleaning was hand excavation, whereby laborers loaded sediment into skips which were then moved down the sewer and lifted out at manhole access points. The work is not only dirty, unpleasant and dangerous; it is also generally very costly. For these reasons it is now only considered when all other methods are not possible for one reason or another.


The purpose of jetting is two-fold - to loosen sediments, debris and material coating the sewer, and to then move this material along the pipe, generally in a downstream direction, to a location from where it can be removed. Removal of the material is normally carried out using vacuum or air-displacement devices, which are now often combined with the jetting equipment and mounted together on one vehicle. Jetting machines for sewer cleaning are usually of the low-pressure-high-volume type, with operating pressures of between 140 and 200 bar and flow rates of 200 up to 750 liters/min. Water is fed at pressure through small diameter (typically around 40 mm) jetting hoses to a jetting nozzle, which can be equipped with both perpendicular jets and backward-inclined jets. The purpose of the jets is to provide the forward propulsive force and to remove material on the sewer walls and invert. Buying these instruments are very expensive, this is the main reason that one should find the best Grand Rapids sewer repair contractor or company.  Check whether the company uses the latest technology in cleaning the drain or sewer lines.
