Sewage area north of Mengeš and under Grobeljska cesta
The Sewerage network in the municipality Menges is part of a single system, which also includes the sewages in the municipality of Domžale, Komenda, Kamnik and Trzin, and ends in the CTP Domžale - Kamnik.
The investment program envisages two segments:
- Extraction and purification of waste water in two areas of the city Mengeš, which have not yet been fitted with drains, namely:
- the area north of Mengeš - over the discharge relief valve and
- the area under the Grobeljska cesta.
- Restoration of other municipal infrastructure in both of these areas, namely, the restoration of the water supply system, street lighting, storm sewers and roads, and TK sewers.
The investment under the item. 1 is part of a joint project with the title The Extraction and Purification of waste water in the area of Domžale - Kamnik, which includes investments in drainage and sewage treatment in the municipalities Cerklje na Gorenjskem, Domžale, Kamnik, Komenda, Mengeš and Trzin. The operation is performed under the Operational Programme for the implementation of the cohesion policy for the period 2014–2020 and is expected to be financed by the Cohesion Fund. Implementation of the planned works carried out from 2014 onwards, the work will be completed in 2016.
Investment in the construction of a sewerage network is - according to the control data - executed in the following scale:
- area A (completed obtained an operating permit
- area B (completed) obtained an operating permit
- area under Grobeljska cesta completed 90 % of construction work.
The investment objectives are:
- to ensure appropriate municipal infrastructure in both of these areas,
- reduction of emissions to water from municipal sources of pollution,
- remediation of pollution sources.
Operation pursues the objectives of the Operational Programme for the implementation of the cohesion policy for the period 2014–2020 to contribute to the achievement of specific objective “Reduction of water due to the construction of infrastructure for the collection and treatment of urban waste water” within the priority axis “Improving the state of the environment and biodiversity”, namely:
- to construct an adequate infrastructure for the extraction and purification of urban waste water, which is registered in the national program as an area that must be equipped with the sewage system in accordance with EU directives on the collection and treatment of waste water and the pre-accession treaty,
- reducing the impact on the environment (water, land).
Upgrade of the Treatment Plant Domžale - Kamnik
The upgrade project of the CTP Domžale - Kamnik includes an upgrade of the CTP Domžale - Kamnik to the tertiary biological treatment with a sequential batch reactor technology - SBR and a construction of the input object with the adoption of the cesspool sludge.
In accordance with the Decree on the emission of substances in waste water discharges from municipal wastewater treatment plants (Official Gazette of RS, Nos. 45/2007, 63/2009, 105/2010), the area of settlement Domžale - Kamnik and the CTP Domžale - Kamnik must provide tertiary treatment until August 22, 2016, which means an additional removal of nitrogen and phosphorus. The cleaning effect of nitrogen and phosphorus compounds from waste water will be unsatisfactory under the new legislation and would - due to surplus of the concentrations - be an excessive burden to the environment.
By upgrading the biological levels of water lines the cleaning effect will be improved and, thus, the quality of the effluent, which will significantly contribute to the reduction of pollution of the river in Kamniška Bistrica will be improved, and be marked with a better ecological status. The CTP will also adopt and clean larger volumes of wastewater when rainfall from the mixed sewerage network. A safe operation within statutory limits and standards will be ensured and the excessive pollution of the environment reduced.
Subject of the project is also to build an entrance building and sludge reception. This will increase operational safety, allow a more efficient elimination of sand and larger particles, arrange adequate hydraulic flow to the CTP, increase the quantities of coarse purification of rainwater and reduce air emissions.
