Lanjik, like other settlements of the Ani consolidated community, gets its drinking water from the only reservoir in the area. However, its capacity is insufficient to provide 936 people with a round-the-clock water supply. The capacity of the newly built reservoir for the village is 150 m³. The water in the reservoir is collected at the expense of gravity water coming from Aragats Mountain. Still, the amount is not enough to fill the reservoir. As a result, water supply in the village is carried out on a special schedule, lasting 3-4 hours every two days.

The Lanjik School was founded in 1902 and has been operating in the current building since 1990. The school is a typical two-story building designed for about 350 students. Currently, the school has 120 students. However, taking into account the state program of consolidation of schools and the increase in the birth rate in the village, it is expected that the number of school children will increase significantly in the coming years.

The school has male/female renovated sanitaries, bathrooms with drinking water taps, and sinks on each floor. However, due to the lack of a round-the-clock water supply, the school's internal network and drainage system are almost non-functional. To solve the problem, it is necessary to install water tanks, where the required amount of water will be collected to ensure water supply during classes at school. To deliver the stored water to the students without loss and with appropriate quality, it is also necessary to repair some parts of the internal network and ensure proper drainage conditions.
