The Central wastewater treatment plant Domžale – Kamnik, treating municipal wastewater, rainwater and industrial wastewater from the areas of the 6 municipalities, ranks this plant the fourth biggest municipal wastewater treatment plant in operation in the Republic of Slovenia and is now representing a model of the current state-of-the-art technique in wastewater treatment in the world.

On the first Saturday in September, a very much notable event took place at the Domžale – Kamnik Central Wastewater Treatment plant (CČN), i.e. the so-called Open Doors Day named The Drop of Life. The event included a presentation of the operation of the existing wastewater treatment plant and plans for its future, more precisely the upgrade of the CČN for the removal of nitrogen and phosphorus from wastewater. Despite the weather being rainy, around 700 visitors gathered who, after taking part in an interesting cultural program, were taken on a tour of the CČN processes where they were familiarised with the background and future plans of the plant. Visitors were also acquainted with the costs which each municipality resident will need to pay for the purposes of wastewater treatment after the upgrade is finished. The tour was finished with information on the beginning of the plant upgrade project.

The event was also attended by Mr Boštjan Petelinc, PhD, acting director of the Water and Investments Directorate of the Ministry of Agriculture and Environment, Mr France Jerič, Mayor of the Municipality of Mengeš, and Mrs Andreja Pogačnik – Jarc, Deputy Mayor of the Municipality of Domžale. In the accompanying program led by Boštjan Romih, the following participated: the Godba Domžale brass band, the Cascara percussion ensemble, zitherist Tomaž Plahutnik and Soprano singer Meta Matzele, including Peter and Andraž Vode. The event was followed by a painting exhibition on the topic of water, organised by the cultural association Kulturno društvo Senožeti Radomlje and the paraplegic artists' association Zveza društva paraplegikov, among the latter also artists who paint with their mouth. In addition, the program was diversified with a number of paintings and drawings also on the topic of water as created by the pupils of the Dragomelj and Stanje elementary schools, while the elementary school of Marija Vera Kamnik presented the project titled Waters connect – water for a clean environment, while at and along the entrance to the event visitors were accompanied by the artistic photographies of Klemen Razinger.

An open doors day, named Life in a Drop of Water, was organised and at the same time a really appealing publication for the event including the thought of Mr Sauvage de Saint Monica: »Water, you are tasteless, colourless, odourless, we cannot define you, and although we taste you, still we do not know you. Life does not need you – you are life«, on the cover of the publication issued.

2007 / Activities of the JP Domžale-Kamnik Central Wastewater Treatment plant were not well known to the local public


As everywhere else, here too clean waters had been taken too much for granted, and this was the reason we wanted to start raising awareness among the public about the importance of the wastewater treatment plant operations with the focus on bringing the operations of the plant closer to the public.

The response was extraordinary as around 150 curious and interested individuals appeared at the event. What was most exciting about the visit was the great interest of visitors in the operation of the plant, where they got the opportunity to study in detail a droplet of water by means of a microscope and listen to a lecture as prepared by our employees. After the closure of the official part of the event, we all relaxed a bit by enjoying a number of gourmet delights and good music.
