Vodoopskrba i odvodnja Ltd. in the 800 km² service area, carries out the activity of delivering healthy drinking water through network of approximately 3500 km with supporting facilities and a wastewater treatment service of approximately 2200 km network with supporting facilities.

Within the scope of wastewater treatment, sewerage and drainage services are also provided as well as maintenance of household connections.



In order to provide the best and top quality service, four vehicles were purchased in December 2019, following a public procurement procedure:
 
  • special small duct flushing vehicle 
  • special small suction vehicle - small drainer
  • two special suction vehicles - a large drainer

In January 2020, two more vehicles were delivered:
  • two special combined flushing and suction vehicles

A special small duct flushing vehicle will be used to clean ducts from 10 cm to 30 cm profiles. It is equipped with a high-pressure pump that pumps water up to 150 bar and breaks the sludge with water through a special nozzle and draws it to the control shaft, where it is extracted with a special suction vehicle.

As most of the connections to the facilities, a special small suction vehicle had to be purchased due to the capacity limitations of the roads. It is used for regular maintenance (cleaning and removal of impurities) of sewage pipelines and drains, suction of sediment and removal of collected material to the landfill. The aforementioned vehicle is smaller in size because of the ability to access certain locations that require it, as well as access to public traffic areas that do not allow heavy loads. It is equipped with a tank for collecting waste from pipelines and drains and a tank with clean water for rinsing and cleaning the drains. The vehicle is equipped with a telescopic branch for suction and cleaning of sediment. A 120 bar high-pressure pump and high-pressure hoses and self-guiding nozzle heads are used for eventual punctures and cleaning.

All other roads with no bearing problems will use a special suction vehicle - a large drainer that has the same technical characteristics as a small vehicle with a larger volume of sludge tank.

A specially combined flushing and suction vehicle is used for the regular maintenance (cleaning and removal of impurities) of sewage pipelines and drains, puncture of clogging, suction of sediment and removal of collected material to the landfill. It is equipped with a pipeline for collecting waste from the pipeline and a tank with clean water for rinsing and cleaning. The vehicle is equipped with a base chassis and a special upgrade. It is also equipped with telescopic branch for suction and cleaning of sediment from hoses with suction hose. A 170 bar high-pressure pump and high-pressure hoses and self-guiding nozzle heads are used for puncture and cleaning.
