Water is essential for life, but it is also a scarce and precious resource in many parts of the world. In Karachi, Pakistan’s largest and most populous city, water supply is a major challenge for millions of residents. According to a report by the World Bank, Karachi faces a water deficit of 50 percent, meaning that the city’s water demand exceeds its supply by half.

One of the ways that Karachiites cope with this water crisis is by installing water tank systems in their homes and buildings. These systems store and distribute water from various sources, such as municipal pipelines, groundwater wells, or rainwater harvesting. Water tank systems can provide a reliable and convenient access to water for domestic and commercial purposes.

However, water tank systems are not without problems. One of the most common and serious issues that can affect water tank systems is leakage. Leaks can cause water wastage, contamination, damage, and increased costs. Therefore, it is important to detect and prevent leaks from your water tank system as soon as possible.

The purpose of this article is to help you understand how water tank systems work in Karachi, why leak detection is important, how to detect leaks using different methods, how to prevent leaks through proper maintenance and protection, how to address common water tank issues in Karachi, and how to comply with local regulations and safety standards for water tank systems.

Understanding Water Tank Systems in Karachi

Before we discuss how to detect and prevent leaks from your water tank system, let us first understand what types of water tank systems are commonly used in Karachi, how they work, and what materials they are made of.

Types of Water Tank Systems Commonly Used

There are two main types of water tank systems that are commonly used in Karachi: overhead tanks and underground tanks.

Overhead tanks are installed on the roofs or terraces of buildings. They are connected to the main water supply line or a pump that draws water from a well or borehole. They use gravity to distribute water to the lower floors of the building. Overhead tanks are usually preferred for high-rise buildings or areas with low water pressure.
Underground tanks are installed below the ground level. They are also connected to the main water supply line or a pump that draws water from a well or borehole. They use a booster pump to distribute water to the upper floors of the building. Underground tanks are usually preferred for low-rise buildings or areas with high water pressure.

How Water Tank Systems Work

The basic working principle of a water tank system is simple: it stores water when it is available and distributes it when it is needed. However, there are some components and mechanisms that make this process more efficient and effective.

A typical water tank system consists of the following components:

Water tank: This is the main storage unit that holds the water. It can be made of different materials, such as plastic, metal, concrete, or fiberglass. It can have different shapes and sizes, depending on the capacity and space available. It can also have different features, such as lids, vents, valves, gauges, filters, etc.
Water inlet: This is the pipe or hose that brings water into the tank from the source. It can be connected to a municipal pipeline, a groundwater well, a rainwater harvesting system, or a combination of these sources. It can also have a valve or a float switch that controls the inflow of water into the tank.
Water outlet: This is the pipe or hose that takes water out of the tank to the distribution points. It can be connected to faucets, showers, toilets, washing machines, etc. It can also have a valve or a pressure switch that controls the outflow of water from the tank.
Overflow pipe: This is an optional pipe that allows excess water to escape from the tank when it is full. It can be connected to a drain or a gutter that leads away from the building. It can also have a valve or a float switch that prevents overflow when the tank is full.
Drain pipe: This is an optional pipe that allows emptying or cleaning of the tank when needed. It can be connected to a drain or a gutter that leads away from the building. It can also have a valve that opens or closes the drain pipe.

Common Materials Used in Water Tanks

The material used for making water tanks can affect their durability, performance, and maintenance requirements. Some of the common materials used for making water tanks are:

Plastic: Plastic is one of the most popular materials for making water tanks because it is lightweight, cheap, easy to install, and resistant to corrosion and rust. However, plastic tanks can also have some disadvantages, such as being prone to cracking, fading, warping, or melting due to exposure to sunlight or heat. Plastic tanks can also leach chemicals into the water, affecting its quality and taste.
Metal: Metal is another common material for making water tanks because it is strong, sturdy, and long-lasting. However, metal tanks can also have some disadvantages, such as being heavy, expensive, difficult to install, and susceptible to corrosion and rust. Metal tanks can also conduct heat or cold, affecting the temperature of the water.
Concrete: Concrete is a less common material for making water tanks because it is bulky, costly, and complex to install. However, concrete tanks can also have some advantages, such as being durable, stable, and resistant to corrosion and rust. Concrete tanks can also insulate the water from heat or cold, maintaining its temperature.
Fiberglass: Fiberglass is a relatively new material for making water tanks because it is lightweight, strong, and flexible. However, fiberglass tanks can also have some disadvantages, such as being expensive, difficult to repair, and vulnerable to cracking or breaking due to impact or pressure. Fiberglass tanks can also absorb odors or contaminants from the environment, affecting the quality of the water.

The Importance of Leak Detection

Now that we have understood how water tank systems work in Karachi, let us discuss why leak detection is important for them. Leaks can have negative impacts on the water supply, health and safety, and cost of water tank systems.

Impact of Water Tank Leaks on Water Supply

Leaks can cause water wastage, which can reduce the availability and reliability of water supply for domestic and commercial purposes. According to a study by the Pakistan Council of Research in Water Resources (PCRWR), Karachi loses about 30 percent of its water supply due to leakage. This means that about 300 million gallons of water are wasted every day in Karachi due to leakage. This is equivalent to the water consumption of about 6 million people.

Water wastage due to leakage can also affect the water pressure and flow in the distribution system. This can result in low or inconsistent water supply for the end-users. Low or inconsistent water supply can cause inconvenience, frustration, and dissatisfaction for the consumers. It can also affect their daily activities, such as washing, cooking, cleaning, etc.

Health and Safety Concerns

Leaks can also cause water contamination, which can pose health and safety risks for the consumers and the environment. Water contamination can occur when leaks allow dirt, debris, bacteria, viruses, chemicals, or other pollutants to enter the water tank system. These contaminants can affect the quality and safety of the water that is stored and distributed by the system.

Water contamination due to leaks can cause various health problems for the consumers, such as diarrhea, typhoid, cholera, hepatitis, dysentery, etc. These diseases can be fatal if not treated properly. According to a report by UNICEF Pakistan, about 53 percent of deaths among children under five years old in Pakistan are caused by diarrhea. Diarrhea is mainly caused by unsafe drinking water.

Water contamination due to leaks can also cause environmental problems for the surroundings. Leaks can pollute the soil and groundwater with harmful substances that can affect the flora and fauna in the area. Leaks can also contribute to flooding and erosion that can damage the infrastructure and property in the area.

Cost Implications of Leaks

Leaks can also cause financial losses for both the consumers and the providers of water tank systems. Leaks can increase the cost of water supply by increasing the amount of water that needs to be pumped, treated, stored, and distributed by the system. Leaks can also increase the cost of water consumption by increasing the amount of water that needs to be paid for by the consumers.

According to a study by PCRWR, Karachi loses about Rs 1 billion (US$ 6 million) per day due to leakage. This means that Karachi loses about Rs 365 billion (US$ 2.2 billion) per year due to leakage. This is equivalent to about 1 percent of Pakistan’s GDP.

Leaks can also increase the cost of maintenance and repair of water tank systems by increasing the frequency and severity of damages and defects that need to be fixed by the system owners or operators. Leaks can also decrease the lifespan and efficiency of water tank systems by causing corrosion, rusting, cracking, or weakening of their components.

Signs of Water Tank Leaks

As we have seen, leaks from your water tank system can have serious consequences for your water supply, health and safety, and cost. Therefore, it is important to detect leaks as soon as possible before they cause more problems. But how do you know if your water tank system has a leak? There are some signs that you can look for that indicate a possible leak in your system. These signs are divided into two categories: visible signs and indicators in water quality.

Visible Signs of Leaks

Visible signs are those that you can see with your eyes or touch with your hands. These signs include:

Water stains and discoloration: If you notice any water stains or discoloration on the walls, ceilings, floors, or furniture near your water tank system, it could indicate a leak. Water stains or discoloration can be caused by water seeping through cracks or holes in the tank or pipes, or by condensation forming on the surface of the tank or pipes. Water stains or discoloration can also indicate mold or mildew growth, which can be harmful for your health and property.
Mold or mildew growth: If you notice any mold or mildew growth on the walls, ceilings, floors, or furniture near your water tank system, it could indicate a leak.

Plumbing codes: These are the standards that regulate the installation, maintenance, and inspection of plumbing systems, including water supply, drainage, waste disposal, and venting. They may cover aspects such as pipe materials, fittings, valves, fixtures, backflow prevention devices, water pressure, water quality testing, and cross-connection control.
Health codes: These are the standards that regulate the protection of public health and safety from environmental hazards, including waterborne diseases and contaminants. They may cover aspects such as water treatment methods, disinfection procedures, sampling frequency, monitoring parameters, reporting requirements, and emergency response plans.
Environmental codes: These are the standards that regulate the protection of the environment from pollution and degradation caused by human activities, including water tank systems. They may cover aspects such as wastewater discharge limits, stormwater management practices, spill prevention and control measures, waste management plans, and environmental impact assessments.

B. Safety standards for water tank systems

Safety standards for water tank systems are the guidelines and best practices that ensure the quality and reliability of the water tank systems. They may be developed by professional associations, industry groups, government agencies, or international organizations. Some examples of safety standards for water tank systems are:

AWWA standards: These are the standards developed by the American Water Works Association (AWWA), which is a nonprofit organization that represents the interests of the water industry in North America. AWWA standards cover various aspects of water tank systems, such as design criteria, fabrication methods, coating materials, inspection procedures, testing methods, operation guidelines, and maintenance practices.
NSF/ANSI standards: These are the standards developed by NSF International (NSF) and the American National Standards Institute (ANSI), which are independent organizations that provide certification and accreditation services for products and systems that affect public health and safety. NSF/ANSI standards cover various aspects of water tank systems, such as material safety, performance evaluation, quality assurance, product labeling, and auditing requirements.
ISO standards: These are the standards developed by the International Organization for Standardization (ISO), which is an international organization that develops voluntary standards for products and services that facilitate global trade and cooperation. ISO standards cover various aspects of water tank systems, such as terminology definitions, quality management principles, environmental management systems, risk management methods, and energy efficiency measures.

By complying with the local regulations and codes and following the safety standards for water tank systems, water tank owners and operators can ensure that their water tank systems are safe, reliable, and efficient for their intended purposes.
