The implementation of the new project will make it possible to create practically waste-free production at Moscow wastewater treatment plants.

Moscow has signed a concession agreement in the field of housing and communal services, according to which the investor will build facilities to extract nitrogen and phosphorus compounds from wastewater.

“The agreement with the concessionaire was signed for 27 years. In two years, he will build facilities, and for the next 25 years he will carry out their operation, maintenance and overhaul. The project will be implemented entirely at the expense of the investor, which will significantly save budget funds. At the same time, the constructed facilities will become the property of the city from the moment they are launched. And the investor will be able to receive income as part of the operation,” said the Deputy Mayor of Moscow for Economic Policy and Property and Land Relations

Vladimir Efimov.

Similar installations are widely used in the largest public utilities around the world, including in Europe and the USA. For Russia, this technology will be innovative.

“The Moscow government has signed a concession agreement under which the investor will invest 8.4 billion rubles in the modernization of treatment facilities. The project involves the use of advanced, widely used technologies to remove nitrogen from sewage sludge and extract phosphorus for subsequent processing into fertilizers. The concession will be implemented as part of the third stage of the ongoing reconstruction of the Lyubertsy treatment facilities,” said the head

Department of investment and industrial policy of the city of Moscow Alexander Prokhorov.

The project is being implemented jointly with Mosvodokanal JSC. This company treats more than three million cubic meters of wastewater per day and annually improves the quality of water returned to nature.

“The introduction of non-waste technologies is another important area of ​​work to protect the environment. At the Lyubertsy and Kuryanovsk treatment facilities, mini-thermal power plants were put into operation that generate electricity from waste. Also, at the Lyubertsy wastewater treatment plant, a technology for processing sand extracted from sand traps was introduced. It is washed from organic pollution, dehydrated, disinfected, after which the sand can be reused in non-residential construction and landscaping. The implementation of the new project will make it possible to create a practically waste-free production at Moscow wastewater treatment plants,” said the head

Department of housing and communal services of the city of Moscow Vyacheslav Torsunov.

The compounds extracted from wastewater will be processed into mineral fertilizer, which will surpass natural analogues in its characteristics, since the release of useful elements will occur in a dosed manner. In addition, phosphorus is a valuable non-renewable natural element.

This is not Moscow’s first concession in the housing sector. In February 2021, the city signed an agreement with a company that will build two plants for the environmentally friendly processing of sewage sludge on the territory of the Mosvodokanal treatment plant. The investor will invest almost 27 billion rubles in the project, and after the facilities are put into operation, they will undertake the thermal treatment and subsequent disposal of the sludge – it will be supplied to cement plants for use as solid biofuel.

Such a mechanism of public-private partnership as a concession makes it possible to attract private funds for the development of urban infrastructure. In total, to date, Moscow has concluded seven concession agreements in such areas as healthcare, road construction, off-street transport, housing and communal services, social services for the population and education.
