PROJECT DESCRIPTION 1.1 Introduction The project aims at improving water supply systems of Echmiadzin town and nearby villages, for the implementation of which CES Consulting Engineers Salzgitter prepared Detailed Design (DD) by the order of AWSC CJSC, financing by World Bank. The final DD carries measures for the improvement of water supply systems of town Echmiadzin town and villages Aygeshat, Dasht, Shahumyan and Norakert. During ToR clarification the design team was guided by the idea to complete the rehabilitation works, commenced in the last years for having improved water supply networks and unimpeded water supply system. During eleboration of DD existing water supply main structures, emergence waste water networks of the project area had been examined, as well as the the main issues, which need to be solved, had been explained. 1.2 Description of the water supply and wastewater systems of the settlements The existing water supplying of the town Etchmiadzin and rural communities are implemented from Bazmaghbyur and Ghazaravan underground sources of the region Ashtarak through three main systems: Bazmaghbyur-Etchmiadzin gravity system (captages) (320 l/sec) Ghazaravan -Etchmiadzin gravity system (deep wells)(350 l/sec) Ghazaravan-Etchmiadzin gravity system (captages) (80 l/sec) The water quality of the mentioned sources coresponds to requirements, determined in the Decree of RA Ministry of Health N876 on “Drinking Water”. Transported water amount is disinfected through two existing chlorination stations. 500l/sec water amount of the total 750l/sec received from headworks is consumed by town Etchmiadzin and 26 rural communities, while the remained 250l/sec water amount is consumed by 13 rural communities of Aragatsotn marz. 6 CES CONSULTING Reconstruction of water supply systems of town Echmiadzin and nearby 4 villages ENGINEERS SALZGITTER Ghazaravan-Etchmiadzin 52km long water main constructed of steel pipes of 350 to 500mm in diameter. The water main feeds the Daily Regulating Reservuars which supplies drinking water to Etchmiadzin town, airport, and 16 rural communities. The Ghazaravan water main was constructed in 1960. It passes through a number of settlements and a number of lately privatized land. There are illegal connections to the water main, on the other hand unregistered water consumption volume index is very high. Bazmaghbyur-Etchmiadzin 44,5km long water main constructed of steel pipes of 400-500mm in diameter. The water main feeds the DRRs serving the distribution network of town Etchmiadzin and nearby 26 rural communities. The main water mains before reaching DDRs of Echmiadzin city, located south-east to Shahumyan village run through rural communities, and partly through privitized parcels of land. In these areas subscribers make illegal connections to the water main, which is the cause of unregisyered water use high index. In addition, due to erosion of pipes often occur leakages from damaged pipes, as well as around connections and hydraulic equipment. The existing chlorine stations have been reconstructed in the head structures, the chlorine equipments of the operating systems have been fully replaced installing modern and reliable equipment. Currently, there are 10 source nodes, 2 chlorine stations in the system. The existing total 14 deep wells for serving town Etchmiadzin and villages are not exploiting. Water is transmitted from the head structures through 300-600mm diameter three main water mains with 136km total length. The water main fed from Bazmaghbyur water source captages is divided into two branches in the village area of Voskevaz, the right branch of which is for the villages Amberd, Aghavnatun, Doghs, Tsaghkakunq and Aragats, but the left one is for Aygeshat, Mrgastan, etc., for water supplying of 10 villages. From the water main branching node nearly (300-350)m lower to the current direction, damping well is constructed in each branch, the aim of which is to maintain water main from the unacceptable pressure (see pic. 1, 2), currently the technical condition of the damping wells is far from being satisfactory. The cover plates are demolished in the result of which passers-by and local inhabitants have free access in them. Moreover, in the irrigation period, the owners of surrounding lands were forced to close water main entrance and water is used for the irrigation purposes through the deprived pipe. 7 CES CONSULTING Reconstruction of water supply systems of town Echmiadzin and nearby 4 villages ENGINEERS SALZGITTER 1.3 Current condition of water supply structures External system Water supplying of the town Etchmiadzin and 4 village communities is implemented from Bazmaghbyur-Etchmiadzin gravity schemes (captages), Ghazaravan-Etchmiadzin gravity schemes (deep wells) and Ghazaravan–Etchmiadzin gravity schemes (captages), town Etchmiadzin is fed from W=(1x6000+1x1000+2x 2000)մ3 volume DRRs located in Shahumyan 934m node and is given to the town 400l/sec flow. Generally 11000m3 volume 4 DRRs are constructed, the 2 of which have 2000m3, the one (airport DRRs) has 1000m3 and the one has 6000m3 volumes. The waters from Ghazaravan and Bazmaghbyur water sources with Փ500-600mm diameter 2 water mains are transmitted to DRRs operating in the south-eastern territory of the village Sghahumyan, which are for the reliability increase of the water supply system work of town Etchmiadzin, nearby villages and airport. Ghazaravan source waters are transmitted to the DRRs territory with 500mm diameter pipe and are disributed into the 4 DRRs. But the waters coming from Bazmaghbyur with 600mm diameter pipe fall into 6000m3 volume DRRs. The water main emerging from Ghazaravan water sources, entering the territory of Shahumyan DRRs, feeds 2 2000m3 volume reservoirs. Before falling into the reservoir Before entering the reservoirs water metering node is constructed on water main, above the disribution node, which is uninstalled and isn’t operating, but the serving valves and connecting water metering nodes, existing on water main, are not maintained. The constructed reservoirs aren’t implementing a regulatory role in the case of existing of the significant leakages
