The company objectives

Network expansion

Continuing processes of population growth, improvement of the standard of living and development of the city, necessitate the expanding of the water supply network by strengthening the main transportation pipelines in existing roads and by laying new lines in the new neighborhoods and in main new roads.

The works are derived from the master plan for the supply of water to Jerusalem and road construction projects of the city's Roads Division, the Moriah Company and the Ministry of Construction and Housing.

The combination of laying water pipes with roads construction works saves the excavation costs, opening and repairing the asphalt, and reduces the disruption to traffic when laying the pipelines. For these reasons, sometimes the network expansion work is carried out in advance.


Replacing the network

Replacement of worn-out water pipes proactively reduces water loss, prevents damage to water quality, and increases the supply reliability.

The standard life span of a water pipe is about 40 years, hence the need to replace about 2.5% of the length of the network every year, which is 1300 kilometers long, namely about 33 kilometers per year. The replacement priority is given to water lines with a large number of bursts and problems, and to sub-diameter water lines.

The company makes an effort to improve the quality of the pipes and the methods of placing them and invests in constant supervision of the network. This in order to extend the life of the network.


Main supply line in Emek Hatemanim

As part of the fifth pipeline project for the future supply of water to Jerusalem, which is currently being implemented by Mekorot, Hagihon is required to carry out a main transmission line in Emek Hatemanim with a length of about 4 km and with a diameter of 60" from Ein Karem connection to Bayit Vegan pool. The project includes the use of tunneling technology.


Pipeline 52" at Mahalei Haromahim

As part of the fifth pipeline project for the supply of water to Jerusalem, which is currently being carried out by Mekorot, Hagihon is required to carry out the main transmission line along Mahalei Haromahim, in a length of about 0.85 km and with a diameter of 52" from Motza connection to Givhat Shaul near Herzog Hospital.


Construction of reservoirs, stations and facilities

Due to the distance of the city from its water sources, Hagihon is constructing in Jerusalem a water collection system that prevents a water shortage from the citizens of the city, and prevents suffering during malfunctions in the water transportation system to the city.

Based on past experience, the company has set a goal of establishing in the city a collection capacity of 1/2 cubic meter per capita. In addition, the mountainous topography of Jerusalem dictates the need to pump water to the city's high areas and pressure reduction facilities to the low areas.

Pumping stations and pressure reduction stations are therefore established as required in the new neighborhoods.


Gan Saker Pool

The collection poll to be built is designed to contain 25,000 cubic meters of water and is intended to meet the growing water needs in the city center.

In addition, the pool is intended to be used by Mekorot to regulate the supply of water to Jerusalem, which is expected to grow significantly following the construction of the fifth pipeline that has just begun. In light of this, Mekorot plans to buy from Hagihon a collection capacity as required for its needs and in return to finance the construction of the pool.


DMA regional measurement systems

As part of Hagihon policy to reduce water lost in Jerusalem, it was decided to build additional regional measurement systems throughout the city. These systems, using measurement meters, will calculate the quantities of water consumed in selected areas and transmit the info daily to the control system located at Hagihon facility.

Day and night consumptions in various areas are known with a good approximation. Therefore, using the measurement systems will enable Hagihon to identify immediately of any extreme deviations in the water supply in a given area, usually resulting from water bursts due to damaged pipes. Therefore, these damages will immediately fixed. Pre knowledge of a water leakage will significantly shorten the loss of water.


Upgrading the Command & Control software and the remote observation system

Hagihon company plans to continue replacing and upgrading the old servers and software systems in the coming year. This is done in order to minimize malfunctions and ensure the continued flow of quality data that provide real-time information to operational personnel regarding the status of Hagihon water supply facilities.


Installing water meters for consumers in East Jerusalem

As part of the desire to reduce waste, prevent water theft and increase the collection rates of water bills in the eastern part of the city, Hagihon continues its activity from previous years, including the laying of water lines and the installation of water meters in various neighborhoods in East Jerusalem.


Installing sensors for detecting water leakage

As part of the project, which some of it is funded by the State, additional fixed sensor installations will continue in areas where they have not yet been installed. The sensors designed to identify bursts in water lines and transmit them to a control center. This info gives us a reliable picture of the pipeline's liquidity, and allows us to act accordingly.


Cleaning of pools

In accordance with the work plan for cleaning the collection reservoirs in Jerusalem, and in accordance with predetermined timetables and in accordance with the directives of the Ministry of Health, Hagihon Company cleans the water reservoirs in order to maintain a good quality of water supply from the pools.
