Infrastructure water supply and sewerage networks
General information
The "Sistem Teknik" project in Plovdiv represents a large-scale implementation of external engineering infrastructure for an industrial facility. Within the project, "Riolit Engineering" Ltd. executes a complete complex of water supply and sewerage networks, ensuring reliable water supply, efficient discharge of domestic, rainwater and process water, as well as a high level of fire protection.
The project investor is Sistem Teknik, and the client is "ATARO Klima" Ltd. The execution covers the full cycle of construction and installation activities – from excavation works to final completion and preparation for operation.
Sewerage infrastructure
The sewerage system is designed and built with a focus on durability, high throughput and safe operation under industrial load conditions. The total length of the constructed sewerage routes is 1,663.55 linear meters.
Pipes made of polypropylene (PP), polyethylene (PE) and PVC-U with diameters from Ø110 to Ø1200 and strength class SN ≥ 8 kN/m², suitable for large depths and loads, are used. Both gravity and pressure sections have been executed, including main collectors with large diameters.
To increase environmental safety, five oil separators have been installed, and for control and maintenance – 45 inspection shafts with diameters DN1000, DN1500 and DN2000, located according to regulatory requirements.
Water supply network and fire protection
The external water supply network is built with a total length of 1,222 linear meters and includes polyethylene pipelines with diameters from Ø32 to Ø400, with working pressure PN10, PN16 and PN25.
The system ensures both reliable water supply to the facility and the required flow rate for fire protection needs. In critical sections, concrete casings have been executed, shut-off valves with diameters DN100 and DN200 have been installed, as well as seven above-ground fire hydrants, located at normatively permissible distances.
Technology and quality of execution
All construction and installation works have been executed in full compliance with the approved project documentation and applicable regulatory requirements. The implementation includes:
- excavation and earthworks;
- laying and compaction of sand bases;
- installation of pipelines and fittings;
- construction of concrete protective elements;
- backfill with controlled compaction.
The materials and technologies used guarantee long service life, high reliability and minimal maintenance costs.
Result
With the implementation of the "Sistem Teknik" project – Plovdiv, a stable and functional water supply and sewerage infrastructure has been built, meeting the high requirements of modern industrial zones. The project is another proof of the expertise of "Riolit Engineering" Ltd. in the execution of complex and large-scale engineering solutions with long-term operational value.
