The Municipality of Rrogozhina has undertaken a project for reconstruction of the water supply network. The problems with the current network are mainly related to the depreciation and malfunction of the current pipelines partially extended to the city’s area. The water supply pipeline does not cover all the central residential area of the city and in particular the suburbs area, urbanized in recent years.
Based on the recent reports done by the Rogozhina WSSC, it turns out that in the areas covered by the water supply network it is not possible to supply more than 75% of the customers. The metered water connections count for 63% of customers who are supplied. The production of drinking water is 107.3 liters/ inhabitant/ day, or 30% less than the norm of 150 l/b/d, and this deficit gets bigger if the current water produced would be offered to the urbanized area as well. If we refer to the continuity of water supply it turns out to be 5.32 hours, which is lower than the national average of 11 hours, and much lower than the 24 hour standard for which the water supply networks are designed.
Investments by the central government in Rrogozhina’s water supply network have been missing for more than 20 years. The last investment for the rehabilitation of the network dates back to 1994. In years 2000 and 2005 some minor investments extended the water supply network with a new pipeline of 1,500 m, which makes up for nearly 10% of the total water supply pipelines. Currently the transmission and distribution lines are highly depreciated. This situation is not only as a result of the lack of investments, illegal connections, but also the depreciation and corrosion of the existing pipelines. Part of these pipelines is cast-iron and steel, that have been installed since over 20 years ago.
Considering the inability to provide the service across the urban area, limited water delivery schedules, inadequate water quality reaching the customers, and the low pressure, the Rrogozhina WSSC has noted a decrease in the number of active contracts with the water utility. Several families have drilled their own wells by providing water independently, even though this way of supply is out of control regarding the drinking water standards, as well as the quantity and sanitary conditions of these wells. This situation makes it difficult for the water utility to collect the water supply service fees, as in the absence of a continuous service, water supply from wells and lack of meters, families refuse to pay the flat rate as defined by the relevant legislation.
The city of Rrogozhina urgently needs the rehabilitation of the entire water supply network. This is evidenced by the examination of previous studies, the concerns of the Mayor Mr. Beqir Nuredini, Director of UK Rrogozhina, Ing. Bujar Meraj as well as the citizens.
Based on the above findings and various analyses, UK Rrogozhina has started the works on the implementation of the project for the construction of the new water supply network. The objectives to be achieved and the basic principles for the implementation of the new project are:
- The new network will cover all the urban areas within the city, including the suburbs. The extension of the network will reach the residential area above the current reservoirs in the north, the east part for the city, up to the pipes factory in the south and up to the roundabout close to the highway in the west;
- The project will provide the proper water supply pressure by making a rational separation of the water flows sent to each of the reservoirs and their coverage areas, in order to have an optimal balance of the water quantity pumped for different levels and pressures obtained after exiting the reservoir. This would enable to use the electricity needed for pumping in the most efficient way;
- The network is designed to be ring-shaped in order to provide the necessary water flow and pressure at each of network connection, at peak times, and in case of any failure;
The accumulative storage capacity will be increased to cover the required water volume, for achieving the 24 hours a day water supply to all customers, and to cover the water needs at peak times;
- Attention will be paid to the most efficient use of existing water utility assets, that can still be used;
- The existing pipeline network will be renewed and replaced with PE 100 pipes according to Albanian and European standards;
- The necessary measures will be taken to treat the current well water, by reducing its hardness up to 20 German degree and lower. In addition other alternative sources will be explored to ensure the required water quantity and quality in time;
- The project foresees a revision of the population growth rate from 2.5% to 1.5%, due to the negative trend of population growth over the last 15 years, as well as based on the data from the Albanian Institute of Statistics (INSTAT).
