Water Supply and Wastewater Systems in Factory Construction | By ONE KARAKADA

In previous articles, we discussed the design and structural planning, as well as electrical systems, in factory construction. Another critical aspect that requires appropriate design is the ‘water system.’

The planning of water supply and wastewater systems, including drainage pipes and wastewater treatment processes, is crucial. These systems must be designed and planned in advance and must comply with government regulations.

Environmental considerations are essential, especially for factory operators and manufacturers in various industries.

We often hear news about factories illegally discharging wastewater, leading to legal action by regulatory authorities. Thus, the design and implementation of water systems should not be overlooked.

Water Supply and Drainage Systems

Planning the water supply and drainage systems in factory construction is a significant step that requires careful consideration, as it affects the safety and operational efficiency of the factory.

Additionally, there are regulations and standards that must be adhered to ensure that the water systems operate correctly and safely. These include:

Water Supply System

The water supply system should be appropriate for the size and usage demands of the factory. For example, using larger pipes when there is high water usage or pipes that are resistant to chemicals when the water contains chemical substances.

Installing air conditioning or related equipment to ensure the water system operates well in all situations, such as installing water chillers or water heaters.

Drainage System

The drainage system should have sufficient slope to ensure that water flows out of the factory without issues. This includes using pipes with adequate slope and without obstacles that could cause blockages.

Using materials that are resistant to chemicals and various environmental conditions to prevent long-term pipe corrosion.

Inspection and Maintenance

Regular inspection and maintenance of water supply and drainage systems are necessary to monitor the condition of the systems and prevent future issues. This includes checking for potential leaks and cleaning the system to reduce lead or sediment buildup in the drainage pipes that could affect water flow and system efficiency.

Planning Water Supply and Wastewater Systems in Factories

The planning of water supply and wastewater systems in factories involves several essential steps to achieve effective and safe operation. These key steps include:

Planning and Design

Conduct surveys and analyze the factory’s needs to determine the appropriate size and capacity of the water supply and wastewater systems.
Design water pipes, holding tanks, wastewater treatment systems, and other structures according to the factory’s needs.

System Selection

  • Choose technology and equipment suitable for the factory’s operations and maintenance needs, such as responsive water supply systems or environmentally friendly wastewater systems.

Installation and Testing

  • Install the systems according to the planned design. Test the systems to verify performance, accuracy, and operational efficiency.

Maintenance and Upkeep

  • Develop a maintenance plan to preserve system efficiency. Regularly inspect and service the systems to prevent problems and damage from use.

Compliance with Laws and Standards

  • Verify and comply with laws and standards related to water supply and wastewater systems to ensure safety and avoid violations.


  • Train employees on the proper use and maintenance of water supply and wastewater systems. Teach operational procedures and compliance with regulations and standards.

Planning water supply and drainage systems in factories is a process that requires meticulousness and caution to ensure the systems operate efficiently and safely, protecting the environment and nearby communities by strictly adhering to relevant standards and regulations.

In summary, the planning and implementation of water supply and wastewater systems in factories are complex processes that demand careful attention at every step to achieve effective and sustainable operation, ensuring safety for both the environment and people.
