Designing a turnkey water supply solution on for Mekorot, Israel's national water company proved to be a major engineering challenge for BERMAD. The Tzafit project involved connecting the Dead Sea to the national desalination system through a 46 km pipeline, beginning at Tzafit pools (450 meters above sea level) and descending to the Dead Sea (380 meters below sea level). This creates extremely high pressure of 83 bar, which needs to be reduced to 5 bar, the standard pressure for domestic use.

In a previous blog post, we described how as a result of rising awareness about energy savings and environment protection, water supply and distribution systems need to be more efficient and be able to operate optimally at minimum pressures. While single-chamber control valves were traditionally used in these systems due to their cost-efficiency, their functionality is limited in such low pressure conditions.

Since the turn of the last century, hydraulic control valves that utilize line pressure as the energy source for their operation have been used in water supply systems. These valves are used for specific control functions that include pressure and flow control, water level control in tanks and reservoirs, remote open and close, and more.

Background

Twenty-four/seven access to drinking water is something that most of us take for granted. However, this is not the case in many countries around the world. In India for example, factors such as rapid development, a growing population, and uneven resource distribution have made it challenging to implement a reliable and sufficient drinking water infrastructure for the large population.

Sewage (wastewater) is produced wherever people live and work and comes from residential, institutional, and commercial sources. Wastewater that comes from industrial processes such as the production or manufacture of goods is classed as industrial wastewater (not as sewage), but may also get sent to sewage systems. All categories of sewage usually carry pathogenic organisms, which can transmit disease to humans and animals and cause damage to the environment. For this reason, in most countries, sewage collection and treatment is subject to strict regulations and standards.

The Challenge

Jerusalem is the capital city of Israel, and it is located in the middle of the country. In addition to the large number of tourists visiting this historical city annually, Jerusalem also has a population of more than 900,000 people, and in 1994, the yearly drinking water consumption was approximately 60M cubic meters; 2,120 cubic feet. In order to meet the future demand of a rapidly growing population, as well as overcome the challenges posed by an ageing infrastructure, Mekorot (the Israeli national water company) decided to implement a new pipeline system. The objective was to deliver water from the national aqueduct and deep wells near the coastline to Jerusalem.

The Challenge

Faced with erratic pressure control and inaccurate leaching rate control, a Chilean mining company, Compañía Minera Lomas Bayas S.A., needed an effective solution. The company had been using manually-operated diaphragm valves and orifice plates to control the flow and leaching rate inside the leaching modules, which meant personnel had to be present at all times to manually open and close the diaphragm valves, which incurred high operational costs.

Cavitation, which can damage delivery networks, is a given in all water supply systems. However, it is a particular concern in Australia where water supplies are already limited. In systems with inadequate pressure controls, cavitation can lead to significant damage, including pipe bursts, and ultimately a pipe burst if pressure is not properly controlled.

Monterrey, the capital city of Nuevo Leon state in Mexico, faces a number of challenges. With the current population of almost five million people, the city has had to develop new sources of water and now relies on surface water for about 60 percent of its water supply. Given its vulnerability to water shortages in the face of continued growth, the city continues to look for ways to mitigate water loss within its distribution system. Leakages, and frequent bursts in distribution lines continue to be a problem.

Yara International, a global company based in Norway, specializes in agricultural products and environmental protection agents. At Yara Norge AS in Glomfjord, Norway, the company needed a simple, fail-safe hydraulic solution for 24/7 water supply. With full redundancy, valves must be able to reduce pressure to required levels through two separate lines. This is true even in the case of a catastrophic failure.

How Bermad designed, developed and delivered a turnkey water supply solution for the Dead Sea region.

The Dead Sea in Israel is a natural wonder which attracts thousands of tourists every year. It’s one of the saltiest bodies of water in the world — so much so that you can float in it, but you can’t drink from it. As the quality and quantity of potable water sources in the area keeps decreasing, the demand keeps increasing —both from the burgeoning hotel industry as well as from agriculture. The Tzafit regional reservoir facility, located some 60 kilometers from the main Dead Sea resort area with the Judea desert reserve in between, was proposed as an alternative potable water source for the region.

The UN estimates that by 2025, two-thirds of the world will live in water-stressed conditions, with 14% of the global population struggling with absolute water scarcity. Seawater desalination may be the answer to this problem. BERMAD Europe worked together with Acuamed at the Campo de Dalías seawater reverse osmosis desalination plant in Almeria, Spain, on a project that involved using desalinated water for irrigation.

Water hammer, or hydraulic shock, is a major concern in bulk water supply systems. It is even more of an issue when dealing with high pressure systems where failure may have a catastrophic impact. It is caused when fluid moving through the system is forced to suddenly stop or change direction, creating a pressure wave that can create vibration and noise, damage pumps and other system components, and even collapse pipes.

Air valves are essential for air control in water systems. They help prevent inefficiency caused by air that is trapped during filling and pressurized operation, as well as to prevent damage in vacuum conditions and pressure surges.

However, air valves are known to leak, especially when located at low pressure points in the water system. This can cause water wastage and interrupt the smooth operation of the water system.

What’s the connection between control valves and smooth take-offs and landings at Berlin Brandenburg Airport?

The Berlin Brandenburg Airport is a 14.7 km2 airport that is situated 18 km south of Berlin, Germany, and is currently under construction. The 6.8-billion-euro project began in 2006 and includes two parallel runways, a six-floor passenger terminal, a 32-meter observation tower, and a museum and gift shop. The facility is designed to handle about 65 aircrafts, with a passenger capacity of up to 27 million per year. The airport is expected to open in autumn 2020.

Air control is a critical factor in water systems. Every water system contains entrapped air, which may reduce flow cross-section, increase energy costs during pipeline filling and pressurized operation, cause pressure surges, interfere with metering or even stop the flow altogether. In addition, there are cases where air cannot enter the network. This can cause vacuum conditions and may lead to pipes collapsing or other mechanical damage to system components.

Proper air control is a vital factor in water system design. Appropriate sizing and placement of air valves is critical to avoid water hammer, head loss, and to achieve optimal efficiency and system longevity. Choosing the right valves for the job is a complex and time-consuming task that requires the designer to take a great number of factors into account, not the least of which includes keeping system costs within budget.
