Municipal Water Treatment: How It Works?

/ Blog / By

Water is an essential resource for human life, industry, and agriculture. In Bangladesh, where rapid urbanization and population growth are increasing water demand, municipal water treatment plays a critical role in providing safe and clean water. The municipal water treatment process involves several stages to ensure that water from natural sources is purified and safe for consumption. In this blog, we will explore how municipal water treatment works in Bangladesh, the processes involved, and the importance of municipal treatment of water in ensuring public health.

What is Municipal Water Treatment?

Municipal water treatment is the process of treating raw water from natural sources like rivers, lakes, and groundwater to make it safe for public use. This process removes contaminants, such as bacteria, viruses, chemicals, and sediments, ensuring the water meets health and safety standards.

The Importance of Municipal Water Treatment in Bangladesh

Bangladesh, with its growing population and urban centers, faces several water-related challenges, including pollution and water scarcity. Municipal water treatment plants play a vital role in:

  • Providing Safe Drinking Water: Reducing waterborne diseases by removing pathogens.
  • Supporting Urban Development: Meeting the water needs of rapidly growing cities.
  • Protecting the Environment: Reducing the discharge of untreated water into natural bodies.
  • Ensuring Water Security: Conserving water resources for future generations.

The Municipal Water Treatment Process

The municipal water treatment process involves several key steps to ensure water safety and quality:

  • Water Intake

      • Raw water is collected from natural sources like rivers, lakes, or underground wells.
      • Screens are used to remove large debris, such as leaves and plastic materials.

  • Coagulation and Flocculation

      • Chemicals like alum are added to the water to bind small particles together.
      • The particles clump together, forming larger flocs that are easier to remove.

  • Sedimentation

      • The water flows into sedimentation tanks, where gravity allows the flocs to settle at the bottom.
      • The settled material, known as sludge, is removed for disposal.
      • Water passes through layers of sand, gravel, and activated carbon to remove remaining particles, microorganisms, and impurities.

  • Disinfection

      • Disinfectants like chlorine or ozone are added to kill any remaining bacteria, viruses, and parasites.
      • Ultraviolet (UV) light is also used in some municipal water treatment plants to disinfect water without chemicals.

  • Distribution

    • Treated water is stored in clean, secure reservoirs.
    • It is then distributed to homes, businesses, and public facilities through a network of pipes.

Municipal Water Treatment Plants in Bangladesh

Several municipal water treatment plants are operational across Bangladesh to cater to the growing water demand. The Dhaka Water Supply and Sewerage Authority (DWASA) operates multiple plants to serve the capital city. Other cities like Chattogram and Khulna have also implemented modern water treatment facilities to improve water supply and quality.

Challenges in Municipal Water Treatment

Despite significant progress, Bangladesh faces several challenges in its municipal water treatment sector:

  • Water Source Pollution: Industrial discharge, agricultural runoff, and domestic waste contaminate water sources.
  • Aging Infrastructure: Many municipal water treatment plants operate with outdated equipment and pipelines.
  • Water Scarcity: Seasonal variations and climate change impact water availability.
  • Public Awareness: Limited public understanding of the importance of water conservation and safe water practices.
