“…Sediments can also accelerate the process of sulfate corrosion of pipes, affect the transformation and biodegradation of wastewater, and be a source of odour emissions. Increased flows in channels can cause leaching of pollutants from sediments, leading to periodic increases in pollutant loads in wastewater flowing into the treatment plant, and affect receiving waters receiving direct discharges from storm overflows of the combined sewer system [10,11].…”

Introduction andObjective. The article analyzes the content of heavy metals and standard physical as well as chemical pollution indicators in different types of sediments from stormwater, combined sewer and sanitary sewer systems. Materials and method. Nickel, lead, chromium, copper, zinc and cadmium, as well as standard physical and chemical pollution indicators, were determined in sewage sediments. Aqueous extracts of sediments samples, taken from storm water sewer inlet sediments traps, storm sewers, sanitary sewers and combined sewers, were prepared in accordance with PN-EN 12457-2:2006. After mineralization, the concentrations of the metals: nickel, lead, chromium, copper, zinc and cadmium in the extracts were determined using the inductively coupled plasma emission spectroscopy technique. Results. The results were analyzed with a non-metric multidimensional scaling algorithm. The heavy metal content was variable depending on the sediments collection site. The heavy metals nickel, lead, chromium, copper, zinc and cadmium were found in the sediments from stormwater inlets, storm sewer and sanitary sewer channels, with variability in the concentration of individual metals. The sediments from the flushing of sanitary sewers and combined sewers did not contain cadmium. Conclusions. The content of heavy metals in sediments varied depending on the sampling location and type of sewer system, indicating the need for detailed monitoring to identify the sources of emissions. Sediments from stormwater sewers have higher concentrations of heavy metals, with those from sewer inlets showing zinc concentrations exceeding regulatory limits, highlighting the variability and potential environmental impact of different sewer systems.

“…In addition to the problems with water level monitoring, another issue that should be mentioned is the accumulation of silt in wells [11][12]. Silt forms from fine soil particles and accumulates at the bottom of the well, thereby blocking the natural flow of water through the sewer network.…”

Due to the global trend towards increased efficiency and environmental friendliness in production, along with the aim to create the safest possible conditions, innovative technologies are being developed and applied more intensively. Today, sewer systems face several challenges such as flooding in manholes, gas accumulation, theft of manhole covers, and siltation in manholes and pipelines. Due to the current circumstances, there is a pressing demand for the enhancement of sewer systems. This study focuses on the development of an early warning system comprising a multifunctional device. The system provides a complete picture of the condition of the contents of manholes and their covers in city sewers or private septic tanks. The test results demonstrate the integration of the module for the automatic detection of manhole openings, the module for the detection of critical liquid levels, and the module for the detection of critical siltation levels. The effective solutions used in this system include the optical infrared sensor TOF400F, the LiDar sensor for distance measurement with TF-Luna, and the infrared sensor YL-63, which is sealed in a cylindrical plastic body with a diameter of 30mm. The distance between the sensor and the manhole should not exceed 30 cm for the first module, while the second module is effective up to a depth of 5 m. Deployment of this system has both social and economic benefits, including increased safety for people, optimization of physical inspection costs for each well, and logistics for service organizations.
