Saudi Arabia is home to one of the most extreme climates globally. Long periods of intense heat combined with low humidity levels, seasonal temperature swings, and frequent sandstorms risk the plumbing systems of residential and commercial properties. The extreme climate of Saudi Arabia affects every aspect of plumbing systems – the impact is greater for industrial and large commercial buildings.
As Saudi Arabia’s premier plumbing engineering firm, we know firsthand the unique challenges faced by all industries in this desert kingdom. In this article, we discuss how weather conditions in Saudi Arabia will affect your plumbing infrastructure and how high-quality engineering designed specifically for this climate will supplement these challenges.
Saudi Arabia Extreme Weather Conditions
In the summer months, Saudi Arabia can reach extreme heat conditions with recorded temperatures over 45°C. During the winter months, many areas within the country experience extremely cold winter nights. Central and Eastern Saudi Arabia frequently experience high levels of sandstorms, and coastal cities are subject to extreme humidity levels and salt-laden air. All of these environmental factors create pressure on all components of plumbing systems, including piping, pumps, valves, drainage systems, and water distribution networks in residential, commercial, and industrial buildings.
Extreme Heat Damage to Plumbing Systems
The heat of Saudi Arabian summers can cause thermal expansion of piping systems, leading to increased joint and seal stress through thermal cycling of the pipe. PVC and inferior-grade plastic pipes will typically deform from this type of thermal cycling, while the metal piping will lose its structural integrity over time due to this type of thermal cycling. Any industry that stores hot water or operates boilers during a peak summer season will likely be adversely affected.
Engineering Solutions
Some engineering companies have developed heat-resistant piping using materials such as CPVC, PPR, and coated steel to withstand the effects of thermal stress. The use of thermal expansion control valves on the piping system will further reduce the amount of pressure placed on the piping system. The application of high-grade insulation to the piping system will reduce the possibility of overheating. Automated temperature monitoring systems allow for the safe operation of piping systems within industrial plants.
Rapid Pipe Corrosion Caused by Salt Air
Coastal Cities of Jeddah, Jubail, Dammam and Yanbu experience pipe corrosion as a result of the corrosive nature of salt within the air around them. Salt within the air and its reaction with metal pipes are the root cause of the corrosion of metal pipes, which will eventually lead to leakage, rust and contamination. The high humidity levels of the coastal areas will accelerate pipe corrosion and the resulting leaks in pipes that provide HVAC drainage and water supply, as well as pipes that provide cooling within industrial facilities.
Engineering Solutions
The use of corrosion-resistant piping materials such as stainless steel 316L, HDPE, and epoxy-coated piping will mitigate the risk of corrosion to the pipes due to exposure to salt air. Anti-corrosion coatings provide long-term protection. Routine cleaning and flushing of piping systems prevents the accumulation of salt. Cathodic protection extends the useful life of piping in industrial operations.
Sand and Dust Clogging Pipelines
In Riyadh, Al Khobar and other central areas, sandstorms have become an enormous problem that affects plumbing systems (water supply), wastewater systems, water tanks on rooftops, etc. Sand can enter the pipes through these areas and build up inside these systems, creating blockage and limiting water flow in addition to creating a failure in other components such as pumps, valves and filtration devices. Sand also causes overflow issues in large commercial buildings due to clogged drains.
Engineering Solutions
Advanced filtering technology eliminates sand from getting into pipelines. Meanwhile, utilizing sealed tanks ensures that dust does not contaminate the water. Industrial-strength strainers will protect any pumps used in commercial facilities. Automatic flushing systems flush out pipes automatically, using minimal downtime for the system. Engineering companies also create specialty-designed drainage systems to accommodate areas heavily impacted by sand.
In Cold Winter Regions – Thermal Shock
AlUla, Tabuk, and Hail experience low winter temperatures. When a pipe carrying hot liquid is suddenly exposed to a cold environment, and those temperature changes are too fast, it will create “thermal shock” in that pipe and can cause cracks in the pipe very easily, thus creating a leak or disruption in the flow of water due to the resulting crack.
Engineering Solutions
Insulation can maintain a pipeline at a constant temperature within a specified temperature range. Insulation made from high-density foam is an excellent option for this type of insulation and is recommended for cold zones. Plumbing engineers also design an equal balance of hot and cold water systems to reduce the amount of stress being put on the pipes. Large-scale industrial-type facilities have temperature-controlled pipe rooms to provide this protection to pipes.
Water Quality Issues in Harsh Climate Areas
A high mineral content is a common feature of ground waters in Saudi Arabia. The presence of hard minerals in water causes hard mineral build-up (or scaling) in pipes. This build-up leads to a reduction in the flow-through of the water and can also cause damaged heating systems and associated downtime and energy loss in industrial processes. Additionally, contaminants in the water cause wear and tear on pumps, boilers and fittings, reducing their useful working life.
Engineering Solutions
Engineering solutions to water quality issues can include water treatment units (softening, reverse osmosis and de-scaling systems) to improve the quality of the water, and anti-scale chemical additive products to help minimize scaling. Automated dosing systems in industrial plants assist in the maintenance of water quality by accurately delivering a predetermined volume of chemical products to each production process. Filtration at the facility level helps in increasing the longevity of production-related systems.
Temperature Variations & Pressure Variations
Rapid expansion of the water with heat may cause pressure surges. The internal pressure increases dramatically with overheating, and very old equipment will fail at the point of a pressure spike. This results in pipe bursts, failure of gaskets/seals, and overloading of pumps. The average industrial operation should be able to operate in a controlled, steady state.
Engineering Solutions
Tips to the pressure change issues can include Pressure-reducing Valves to prevent the possibility of excessive pressurization; Smart Sensors to alert maintenance personnel of potential failure prior to occurrence, and expansion tanks to absorb and mitigate the pressure variations. Automated pressure management systems are the recommended solution for all industrial networks.
Damage to Outdoor Plumbing and Exposed Systems
Extreme heat is the leading cause of pipeline damage in Saudi Arabia. The sun’s UV rays weaken pipe surfaces. Therefore, pipeline surfaces constructed at large facilities (such as above ground, on roofs and outside walls) deteriorate quickly due to exposure to sunlight.
Engineering Solutions
UV-resistant pipe coatings protect the pipe surface from UV rays. Shade structures reduce heat accumulation. Underground piping can be laid at a greater depth to protect against sun damage. Engineering companies design concealed piping systems to provide a longer life and greater safety.
Plumping Systems Lose Efficiency in Extreme Heat
Extreme heat requires more effort from pump systems. It causes the cooling systems of pumps to work harder and affect motor and mechanical operation—causing the pump motors to operate at higher than normal temperatures—resulting in reduced efficiency and increased cost of electricity. In industrial facilities, this type of pump failure can shut down an entire manufacturing operation.
Engineering Solutions
High-efficiency pumps manufactured for operation in hot environments perform better because they are designed to dissipate heat and have superior motor protection systems. Cooling systems designed for use with pumps in industrial environments do create enough heat to stop the safe operation of a pump. Plumbing companies in KSA are now using frequency-controlled pumps to reduce energy costs and maintain a constant output of pumps.
Effects on Drainage Networks During Sudden Rain
Whether due to large storms that have hit Saudi Arabia over the last few years or due to recent flooding, many cities around the Kingdom of Saudi Arabia have experienced drainage problems. Only some of the cities have received rainfall in amounts exceeding 5 inches (130 millimetres), and some areas received as much as 10 inches of rain (250 millimetres). The amount of rain falling on Saudi Arabia has caused both a rapid increase in water level across the nation and a rapid rate of water flow away from populated areas.
Heavy rainfall has caused increased stress on the drainage and storm systems of the Kingdom. Many of the major industrial cities in Saudi Arabia are currently experiencing severe drain blockages caused by the build-up of water and the associated damage caused by excess water. Additionally, several types of infrastructure have been built in Saudi Arabia that do not allow adequate drainage, and these factors together have resulted in damage to buildings and other property throughout the Kingdom.
Engineering Solutions
The installation of large diameter drain piping that is designed at a proper slope, and using large volume channel systems, is the most effective method to prevent flooding of the surrounding area. In order to prevent back-flow into buildings in the area, back-flow preventers have also been installed by local engineers of the buildings in the surrounding area. Finally, the installation of modern trench-type drain systems has been very beneficial in discharging the large volumes of stormwater produced in these regions.
