The water reserve is decreasing, but sufficient for large urban settlements

A volume of 3.03 billion cubic meters of water is currently available in the main 40 reservoirs (with complex use) administered by the National Administration “Romanian Waters” (ANAR), respectively Hidroelectrica, according to a press release of the institution.

The amount of water is decreasing from 3.45 billion cubic meters, as it was at the beginning of July 2022, but ANAR representatives specify that the reserve is sufficient for large localities, which are fed centrally from the surface water source.

Currently, the occupancy rate is 70.04%, almost 10% less compared to July, when it was around 80%.

We estimate that, at the end of August, in the 40 main reservoirs with an important role in the water supply for the population, industry and the production of electricity for the National Energy System, we will manage to maintain a filling coefficient of over 62%. At this moment, out of the 120 hydrological drought monitoring sections, in 24 of them flow rates were recorded below the minimum necessary to satisfy the water requirements from a quantitative aspect. In these sections, the water requirement for all uses cannot be ensured at the same time. That is why it is necessary to apply the Plan of restrictions and use of water in periods of scarcity. Each use sets its own thresholds and flows that can be restricted. These are an integral part of the Restriction Plans that are applied gradually according to the three steps, in compliance with the legislation in force’, the cited press release states.

Currently, the Restrictions Plan for fishing and irrigation uses is mainly applied, especially on the Danube sectors related to the Buzău-Ialomiţa and Dobrogea-Litoral hydrographic basins. Also, for inland rivers, the Restrictions Plan is applied, especially for fishing uses in the Prut-Bârlad hydrographic basin.

The specialists from “Romanian Waters” call for calmness and social responsibility and recommend the rational use of water resources in order to save them. “For household activities, we recommend, where possible, to resort to the use/storage of water from alternative sources (including rainwater, when possible), so that drinking (drinking) water reaches everyone,” notes the institution .

According to the monitoring report carried out by ANAR, as well as from the level of the Water Basin Administrations, the counties most affected by the drought phenomenon are: Botoşani, Iaşi, Vaslui, Galati, Suceava, Neamţ, Bacău and Vrancea, especially where there are no a centralized supply system, and the water requirement is provided mainly from wells or boreholes.

At the national level, there are 668 localities supplied with a restricted program, respectively: 252 localities (from 22 counties) that have water supply systems (Botoşani, Iaşi, Vaslui, Galati, Suceava, Neamţ, Bacău, Vrancea, Hunedoara, Mehedinţi, Bihor, Teleorman, Braşov, Ilfov, Argeş, Giurgiu, Dâmboviţa, Buzău, Ialomiţa, Dolj, Gorj and Bihor); 416 localities (from 12 counties: Botoşani, Iași, Vaslui, Galati, Neamţ, Bacău, Suceava, Vrancea, Olt, Gorj, Dolj, Hunedoara) that do not have water supply systems.

In all these localities, the water supply is provided from the underground water source. It is about a percentage of 20-30% of the total number of wells that are partially dry.

The INHGA forecast reveals that the flow of the Danube, upon entering the country, was decreasing to the value of 1,800 m3/s, less than half of the multi-year average of August (4,300 m3/s). At the same time, the water levels registered an increase downstream of Portile de Fier, on the Gruia – Calafat, Turnu – Măgurele – Zimnicea and Isaccea – Tulcea sectors, stationary on the Bechet – Corabia, Giurgiu – Olteniţa and Galati sectors, respectively decreasing on the Călăraşi – Brăila sector.

At the Cernavodă hydrometric station, there are no problems in ensuring the flow required for the operation of the two groups of CNE Cernavodă, as there are still 0.57 meters (57 cm) to reach stage II (warning).

For the next period, hydrologists estimate that the flow of the Danube river, at the entrance to the country (Bazias section), will increase and will reach the value of 2,600 m3/s by the end of August.

As for the situation on the rivers, the flows were increasing due to the rainfall that fell in the interval and the propagation, with the exception of the rivers in the hydrographic basins: Tur, Vedea, Trotuş, Putna, Râmnicu Sărat, Buzău, Bârlad, the middle and lower basins of Argeș, Moldavia, Suceava, Prut, the lower basins of Jiu and Ialomiţa and the rivers of Dobrogea, where they were, in general, stationary. On the other hand, on the Small Someş, Aries, the upper course of the Prut and on the middle and lower course of the Someş, the flows were decreasing.
