What is a Dissipater?

Definition of a Dissipater in Construction

Any assembly or product that provides a dissipation effect on either lighting, energy, water flow, etc. In most cases, the term is used on the site plan to identify the dissipation of water flow out of a storm water outlet or in a flowing stream of water, such as a brook or river. Many times a water flow dissipater is simply the proper placement of boulders within the stream bed, to prevent a constant uninterrupted flow of water from channeling or eroding the intended water channel.

In some cases, the dissipater can be a precast concrete element that is designed to dissipate the energy within the flowing water stream. The term in the construction industry can be any dissipation, or breaking down, of an element on a construction project.
