The utility company «Mykolaivvodokanal» is going to upgrade the water supply network along 3 Slobidska Street — from Chkalova Street to Zavodska Street.

This is evidenced by data from the ProZorro public procurement system, according to NikVesti.

The announced cost of reconstruction of the water supply system is 15 million hryvnias. The funds were allocated to the water utility by the Danish Refugee Council in Ukraine, according to the tender documents.

The contractor will have to use these funds to upgrade the 150-millimetre diameter water supply network by laying polyethylene pipes underground by 4 November 2025. After completion of the main works, the contractor will have to improve and green the territory. The last stage will be flushing, cleaning and disinfecting the pipelines.

Before starting work, the contractor must also receive a 20% advance payment. However, subsequent payments will be made in accordance with the actual work performed.

The tender process is currently underway and the contractor will be selected on 5 March.

Water supply for Mykolaiv

Almost three years have passed since Russian troops damaged the water supply pipeline that supplied Mykolaiv with water. Since then, the city of almost half a million people has been without a centralised supply of drinking water. Currently, Mykolaiv residents receive water from a backup source, which raises many questions about the quality of the water and the salt content.

The salt water damaged 1,200 kilometres of the city's water supply network. Boris Dudenko, director of «Mykolaivvodokanal», said that it is impossible to replace the entire length of the network that was damaged by salt water. As of August 2024, only about 3 kilometres of the network had been replaced.

All this time, representatives of state and local authorities were looking for options to restore drinking water supply in Mykolaiv. The final solution was found in 2024: a new water supply system would be laid from Nova Odesa, and the money was allocated from the state budget.

The Regional Reconstruction Service has already selected contractors who will work according to the principle of «design-build». They are three companies, each of which is responsible for one of the three work areas: «Ukrtransmist», «Rostdorstroi» and «Motorway».

The future water pipeline for Mykolaiv is expected to be built and launched by autumn 2025, said Serhii Sukhomlyn, head of the State Agency for Reconstruction.

However, the question of the new water supply system's design capacity remains unresolved: on the one hand, there is an opinion that water consumption in Mykolaiv has decreased, and therefore a new calculation needs to be made, and on the other hand, limiting the amount of water can directly affect the future development of the city and its industry.

Back during the conference in Berlin in 224, the First Deputy Speaker of the Verkhovna Rada, Oleksandr Kornienko, answering a question «NikVesti», said that the lack of drinking water in Mykolaiv was one of the biggest problems in Ukraine that the state should solve in the near future.

And President Volodymyr Zelenskyy has ordered the construction of a new water supply system to provide Mykolaiv with drinking water «under the fast track option» - drinking water should be available by the summer of 2025. The government has already approved the programme.

Construction of the new water supply system began in early 2025. The cost of the work was reduced from 8.7 billion hryvnias to 5 billion hryvnias. This became possible after a detailed analysis of the project, which revealed several planning errors.

Initially, a new water supply system for Mykolaiv was promised to be built by autumn 2025. But, as reported by the European Investment Bank, this does not guarantee that the city will immediately receive drinking water, as a new water treatment system needs to be built.

Later, the State Agency for Reconstruction reported that the centralised supply of drinking water in Mykolaiv was expected to be launched by August 2025. At the same time, Mayor Oleksandr Sienkevych spoke about «a temporary solution» that would help bring drinking water to the city simultaneously with the launch of the new water supply system.

What is the capacity of the water supply system?

Initially, the water supply system was planned to be built with a capacity of 160,000 cubic metres per day. However, later they started talking about the possibility of reducing this figure to 100,000 cubic metres, based on the city's current water consumption.

Currently, Mykolaiv residents consume between 75,000 and 108,000 cubic metres of centralised process water per day. But in the future, water consumption may be higher, as there are no large enterprises operating in the city today, and the population is still below pre-war levels.

However, official calculations were to be provided to the State Agency for Reconstruction by the Mykolaiv Regional Water Authority. They calculated two construction projects to determine the capacity of the water supply system: 120 or 160 thousand cubic metres per day.

And in February 2025, Vitalii Kim, head of the Mykolaiv Regional Water Authority, said that reducing the cost of building a new water supply system would not affect water quality, but could affect the volume of water supplied to the city.
