A sewage treatment plant (STP) is an important investment for any industry. When it is installed correctly, it treats wastewater safely, meets pollution control norms and runs smoothly for years. When installing sewage treatment plant wrongly, it can cause poor treatment, high running costs, penalties and constant repairs. Many of these problems are avoidable mistakes made during installation. In this blog, we understand 5 common mistakes industries make while installing a sewage treatment plant and how to avoid them.
5 Mistakes Industries Make While Installing Sewage Treatment Plant & How to Avoid Them
Mistake 1: Choosing the Wrong Plant Capacity
One of the most common mistakes is installing a plant of the wrong size. If the plant is too small, it cannot handle the full flow of wastewater, especially during peak hours. This leads to poor treatment and overflow. If the plant is too large, it costs more than needed and does not run efficiently. Many industries do not take future growth into consideration. As the business grows, wastewater increases, and an undersized plant cannot cope.
How to Avoid It: As per STP manufacturers in India, choose the plant capacity based on your actual wastewater flow and your expected future needs. A proper study of your water use should be done before deciding the size.
Mistake 2: Choosing the Wrong Treatment Technology
There are different types of water treatment technologies used in STPs, and each suits different needs. Some industries select a technology based only on low price, without checking if it suits their type of wastewater, available space, and required treatment level. The result is a plant that does not treat the wastewater properly or is expensive to run.
How to Avoid It: Select treatment technology that matches your wastewater type, load, available space, and the treated water quality. An experienced water treatment plant company in India can recommend the right technology for your project needs.
Mistake 3: Ignoring Effluent & Compliance Requirements
Every industry must meet the discharge standards set by the pollution control board. A common mistake is installing a plant that does not meet these standards. If the treated water does not meet the required quality, the industry can face penalties, notices, or even a shutdown. Fixing a plant later to meet the rules is expensive and time-consuming.
How to Avoid It: Design the plant to meet the discharge standards that apply to your industry from the start. Compliance should be planned into the design, not added later.
Mistake 4: Compromising on Equipment Quality
At times, to save money, some industries choose the cheapest equipment and materials. This often turns out to be a false saving. Low-quality pumps, blowers, and other parts break down often, corrode quickly, and need frequent repairs. This increases downtime and long-term costs and can affect treatment quality.
How to Avoid It: Invest in good-quality, reliable equipment and materials. Quality equipment lasts longer, runs better, and lowers your total cost over time.
Mistake 5: Overlooking Operation & Maintenance
Many industries focus only on installing sewage treatment plant and forget about running it properly afterwards. A sewage treatment plant needs regular operation and maintenance to work well. Without trained operators, a proper maintenance plan, and regular checks, even a good plant will start to fail. Poor maintenance leads to breakdowns, poor treatment, and higher costs.
How to Avoid It: Plan for operation and maintenance from the beginning. Make sure you have trained operators or a maintenance service, and follow a regular maintenance schedule.
