Tender Details

Reconstruction of the Søholt sewage treatment plant - Market dialogue Silkeborg Municipality is faced with having to expand and renovate the Søholt Wastewater Treatment Plant. The facility must be expanded so that it can meet future requirements for cleaning and Silkeborg Forsyning's visions and strategy for climate and sustainability, as well as population growth in Silkeborg municipality. At Søholt Renseanlage, the waste water is cleaned mechanically, biologically and chemically with nitrogen and phosphorus removal as well as post-filtration via sand filters. A digestion tower and a biogas plant make the treatment plant approx. 20% self-sufficient in energy. The Søholt Wastewater Treatment Plant is designed for 105, 000 PE (approved capacity of 99, 480 PE) and faces an expansion to approx. 160, 000 PE. Expansion and renovation of the treatment plant is planned to be tendered as a turnkey contract including boats building and construction works as well as delivery and installation of process plants. Silkeborg Forsyning is in the process of preparing the tender material for the tender, which is expected to be completed in the period Q2-Q4 2027. Prior to the implementation of the tender, Silkeborg will Supply to carry out a market dialogue with the aim of obtaining the market's immediate input regarding the basic elements of the upcoming tender material.
