Kyiv faces a growing risk of a sewage crisis this winter because continued power disruption could prevent the city’s electricity-dependent wastewater system from pumping sewage to treatment plants, according to a report published on 20 October 2026. The utility normally pumps around 700 million liters of clean water daily, while sewage pumping and the Bortnychi treatment plant face rising operational risk. The Kyiv Independent
Key takeaways
- Kyiv’s water system requires enough electricity to draw water from the Dnipro River and pump around 700 million liters of clean water daily to households and businesses. The Kyiv Independent
- Untreated sewage could flood the city and create serious health and environmental hazards if electricity failures stop the wastewater system from transporting sewage to treatment plants. The Kyiv Independent
- Drone and missile attacks have directly targeted Kyiv’s Bortnychi sewage plant on several occasions, while sewage pumping stations are also at risk of damage. The Kyiv Independent
- Kyivvodokanal is operating 103 generators across its network and expects additional high-capacity generator systems, but generators cannot replace the main grid or operate continuously. The Kyiv Independent
What happened
Regular Russian strikes on energy facilities have left parts of Kyiv without running water, increasing concern that further outages could affect sewage collection and treatment. The city’s water system depends entirely on electricity, including for drawing water from the Dnipro River and pumping around 700 million liters of clean water each day to households and businesses. The Kyiv Independent
The immediate infrastructure concern is sewage transport. Electricity is required to move sewage to wastewater plants; if untreated sewage is not removed, it could flood the city and pose serious health and environmental hazards. Oleksandr Skhin, director of Ukraine’s Association of Water Utilities, warned: “Transporting and treating wastewater is a major challenge for utility companies. Equipment is aging, and a lack of electricity for pumping can have serious consequences.” The Kyiv Independent
Attack and outage pressure
An attack on Kyiv’s substations on 14 October left many households without water and power, while the city subsequently returned to scheduled power outages. The report said Kyiv lacked sufficient backup generation for the heating season, and voltage fluctuations were accelerating wear in the city’s aging electrical water-utility system. The Kyiv Independent
Russia has increased the intensity of attacks on Ukraine’s energy system fivefold since 2024, according to Olena Pavlenko, head of the Kyiv-based energy think tank Dixi Group. Oleksii Andriiashchenko, sales manager at Grundfos Ukraine, said the weakened grid makes it harder to meet pumping stations’ electricity requirements. He expects parts of Kyiv to lack electricity and water for weeks during the winter and warned that a system collapse could cause sewage tanks to overflow and flood the city. The Kyiv Independent
Mykhailo Yatsuk, director of the Institute of Water Problems and Land Reclamation, said drones and missiles have directly targeted the Bortnychi plant on several occasions. “The destruction of the Bortnychi plant poses the greatest threat. Furthermore, there is a risk of damage to sewage pumping stations,” he said. The Kyiv Independent
Mitigation remains incomplete
Kyiv authorities have emergency plans, stockpiled repair materials and operating 103 generators across the water network, according to the report. Mayor Vitalii Klitschko said more high-capacity generator systems were being manufactured abroad, but also noted that generators cannot replace the main grid or run continuously. The Kyiv Independent
Andriiashchenko said generators can power smaller pumping stations rather than larger, more critical facilities. Petro Panteleev, first deputy head of the Kyiv City State Administration, said the city still needs new high-capacity generation facilities such as co-generation plants to fully back up the water system. Kyivvodokanal is also facing staffing and funding shortages, with one person reportedly doing the work of four. The Kyiv Independent
Even trucked drinking water would not cover citywide sanitation and hygiene requirements. Skhin cited average household consumption of 100 liters per person per day, making the operational significance of a sustained water interruption broader than drinking-water supply alone. The Kyiv Independent
Specification read
The reported scale is an electricity-dependent municipal water and sewer service that pumps around 700 million liters, or 700,000 cubic meters, of clean water each day; the source did not report the corresponding sewage-treatment flow, population equivalent, wastewater load, or required treatment capacity. The Kyiv Independent
The event bears directly on the collection, pumping, biological-treatment and site-disinfection stages of a conventional municipal train: screening and primary clarification, followed by a biological process such as A2/O, MBR, MBBR, SBR or UASB and then tertiary treatment or disinfection. DAF could be relevant where the wastewater requires solids removal, while ZLD would require additional process and energy information that the source does not provide. Municipal wastewater treatment and integrated sewage treatment therefore matter most to an enquiry focused on treatment continuity and standby power.
For operators and buyers, the practical issue is not merely treatment chemistry but the electrical dependency of screening, pumping, aeration, disinfection and sludge handling. If your plant looks like an electricity-dependent municipal system with a reported clean-water flow of 700,000 m³/day, a wastewater flow and load that have not been disclosed, and pressure to maintain collection and treatment during outages, the missing plant data must be confirmed before equipment can be specified. A comparison with water purification equipment alone would not address the sewage-pumping exposure described in the report.
FAQ
What treatment capacity would be needed for Kyiv’s wastewater system?
The source reports that Kyiv’s water utility pumps around 700 million liters, or 700,000 m³/day, of clean water, but it does not state the sewage flow, population equivalent or design load. Operators would therefore need verified wastewater-flow and influent-quality data before defining biological capacity, solids handling, disinfection or standby-power requirements. The Kyiv Independent
How much does a generator-based wastewater system cost?
The source does not report equipment costs, installation costs, fuel costs or a procurement value for the 103 generators already operating across Kyiv’s water network. A cost comparison would need the number and duty cycle of generators, the electrical load of each pumping station, treatment-process power demand, fuel assumptions and the required duration of independent operation. None of those inputs is supplied in the report.
How long would replacement pumps and treatment equipment take to deliver?
No delivery lead time for replacement pumps, treatment equipment or the additional high-capacity generator systems is reported. The source says more generator systems were being manufactured abroad, but a buyer would need confirmed delivery schedules, site-access constraints, commissioning requirements and the availability of critical spares before comparing alternative supply arrangements.
Which critical parts should a utility prioritize for outage resilience?
The reported failure chain begins with pumping stations that move sewage to treatment plants, followed by treatment-plant operation and the risk of overflowing tanks. Screening, pumping, biological treatment, disinfection and sludge handling should therefore be reviewed as one electrically dependent process train. The report identifies pumping stations, the Bortnychi plant and backup power as immediate concerns, although it does not provide an equipment-by-equipment resilience standard. The Kyiv Independent
