General Information: The villages of the Khashtarak cluster mainly belong to the Akhstev river basin. The village’s water supply is realized by underground reservoirs that have very small seasonal alterations.
According to the Ijevan and Sev Qar meteorological station observations, the community’s average precipitation over the period of one year is 520 mm, 30% of which falls in the months of May and June. The absolute maximal temperature of the region is 36°C in July and its minimal temperature is -23°C in January. The average yearly temperature of the region is 10.6°C.
Aknaghbyur
Background Information: The drinking water supply of the village (population 506) comes from three different water springs.
The upper side of the village, about 10 houses, uses the water source called Lulavor that provides 0.5-0.6 liter/sec water flow. The water source is connected to a 20m3 reservoir that supplies water to the upper side of the village.
The main water supply of the village is the Khachi Aghbyur that has approximately 22-25 liter/sec water flow.
The lower part of the community (approximately 90 households) gets water supply from this source through gravity flow. The community uses a pumping station that is located close to the Khachi Aghbyur to supply water to the houses that are located higher than the water source.
Up to 1993 the water from Khachi Aghbyur was being pumped to the 250 m3 reservoir located on a hill. The reservoir supplied the internal distribution of the upper part of the community through gravity flow. The floor of the water reservoir on the hill is damaged and is not functioning today.
The community has also the third water resource – the Khachunts Aghbyur, which has a tap and the nearby capitation are carrying the water from the source to their houses.
Technical Details: The Khachi Aghbyur pumping station has a MC type pump with 38m3/hour pumping capacity. The pump operates with 132m pressure and has 40 kW power. The size of the pumping station is 5 × 6 m. The pumping station is in poor condition; the roof and the floor are in need of reconstruction. The existing pump technically is in normal condition, although it is not energy efficient. The pumping station needs a second pump for more efficient operation. The diameter of the pressured pipe is 100mm, the length is 1.2km.
The condition of the capitation that supplies the Khachi Aghbyur is satisfactory; the service platform needs renovation.
Sanitation: The capitation of Khachi Aghbyur has a sanitary zone that is surrounded by a metal fence. The internal water distribution network of Aknaghbyur lacks disinfection equipment and the water today is used without proper disinfection/treatment (see appendix 7 for potable water plan).
Ditavan
Background Information: The drinking water supply of the community (population 429) is derived from four different water springs located at a place called Kharhatak. The springs are located 2 km far from the village. The amount of water provision from each source varies and is approximately 3.5-4 liter/second.
Technical Details: The springs have capitation structures that were built in 1960s. The community has four 60m3 daily regulating water reservoirs that are 8 km far from the water source and are connected to the capitation structure with 50mm diameter pipes and receive water through gravity flow. The reservoirs are located in the upper and middle parts of the village. The water from reservoirs is distributed to the households through internal network. The internal distribution network has been built in 1966-1967. The length of the internal distribution network is 2.5 km. Today it is in poor condition and needs renovation.
Sanitation: The capitation structures of Kharhatak are not hermetically closed and do not have sanitation zones (see appendix 8 for potable water plan).
Lusadzor
Background Information: The community is mainly supplied with water from Zani spring, located around 1km away from the village. The waterline takes its start from the capitation built in the 1950s on the spring. The water coming out of the capitation amounts to 1.3-1.4 liters per minute. Around 70% of the spring’s capacity is used for the needs of the community; the rest of the water flow is directed to the nearby river.
There is another water source (1.6 liters per minute), around 20m away from the existing capitation, which does not enter the waterline.
Technical details: The waterline connected to the capitation as well as the internal distribution network were built in the 1950s and are currently in poor technical condition. In the upper district of the village there are two water distribution sources serving the needs of the local population.
Taking into consideration the age and poor condition of both the capitation and the associated pipelines it is necessary to upgrade the system according to the modern standards. It is also essential to reconstruct and enlarge the existing capitation and install a new one on the unused spring.
Sanitation: The existing capitation does not meet the existing sanitary requirements. As a part of reconstruction and enlargement process it is essential to ensure that all the required sanitary norms are maintained
(see appendix 9 for potable water plan).
Khashtarak
Background Information: The drinking water supply for the community (population – 1905) is being derived from four different water sources that are located in the administrative territory of Lusdahovit. The two communities – Khashtarak and Lusahovit use the same water resource for water supply.
The total amount of the water in the four springs is 12.5 liter/sec or 1080m3/day. These numbers include the Glul spring – 2.5 liter/sec, Erkar-tala spring – 3 liter/sec, Ortakhner spring – 4.5 liter/sec and Popoknut spring – 2.5 liter/sec. These sources are located on a 900-1200m absolute point.
Technical Details: The water from the four springs is redirected through 100mm diameter pipes to Khashtarak Lusahovit water distribution point which is around 90m above the average altitude of Khashtarak. The pipeline was built in the end of 1960s and is currently in poor condition.
The distribution point redirects the water flow to the internal distribution networks of Khashtarak and Lusahovit.
Khashtarak water supply system has two daily regulation reservoirs with 500m3 and 200m3 capacity. Both are in need of repair and have not been used for the last 20 years because of water leak issue.
Sanitation: Currently, the sanitation norms in the Khashtarak and Lusahovit water distribution networks are not maintained (see appendix 10 for potable water plan).
Lusahovit
Background Information: The drinking water supply for the community (population 440) is derived from four different water sources that are located in the upper part of the village.
The total amount of the source water is 12.5l/sec or 1080m3/day, where also the source “Glul” 2.5 l/sec, “Erkar-tala” 3 l/sec, “Ortaxner” 4.5 l/sec and “Popoknut” 2.5 l/sec.
The sources mentioned are located in the 900-1200m absolute point.
Sanitation: The village Lusahovit doesn’t have an everyday regulating reservoir and the water distribution is being done right from the water springs without disinfection.
The water is flowing to the dividing net from the dividing points of Khashtarak and Lusahovit villages (see appendix 11 for potable water plan).
