A sewer deposit is a complex mix of minerals and organic materials whose dynamics remain difficult to ascertain. On way to improve the knowledge held on sewer processes consists of obtaining detailed long term measurements. This paper will present the technique developed for long term monitoring of sediment height within a combined sewer. The aim of this device is to acquire long term record of the sediment height evolution. The current state of the art is discussed and the technical constraints are exposed. Next feasible technical choices are explained and then results are provided and discussed.
