Effective sewage treatment is crucial to ensure safeguarding of public health, environmental protection, and compliance with relevant regulations. When it comes to STP plants, there are two options: decentralised and centralised sewage treatment plants. In this blog, we have a closer look at these two sewage treatment plant options to help you make an informed decision and choose the right STP system for your specific needs.
Decentralised vs. Centralised Sewage Treatment: An Overview
What is a Decentralised Sewage Treatment Plant?
A decentralised sewage treatment plant is a system that operates at or generation of wastewater instead of relying on a centralised treatment facility. It is an adoptable & long-term solution for rural areas and remote communities.
What is a Centralised Sewage Treatment Plant?
A centralised sewage treatment plant is a large-scale wastewater treatment system that collects, treats and processes sewage water from residential areas, industrial establishments and commercial properties. Ravi Enviro Industries Pvt.Ltd is a leading water treatment plant company in India can help you choose the right system to meet your specific treatment goals. We can provide STPs for diverse industries with tailored solutions specifically for your needs. To discuss your requirements, call us.
Decentralised vs. Centralised Sewage Treatment: Comparing STP Systems
Costs
Centralised sewage systems require a higher initial investment, particularly related to infrastructure, installation and large-scale facilities. When it comes to decentralized wastewater treatment systems, they are more cost-effective. However, over a period of time, centralised STP may have lower economies of scale, and decentralised STP may have variable costs depending on efficiency and maintenance. Collection and disposal or reuse of treated wastewater from decentralized sewage treatment plants requires a lesser distribution network whereas centralized sewage treatment plants require a huge network for collection of sewage as well as distribution of treated wastewater and apparently its maintenance cost.
Environmental Impact
The centralised sewage treatment plants consume more energy and have a significant carbon footprint due to the system’s infrastructure, transportation, and operational costs. While decentralized STP’s are a more sustainable option as they treat wastewater at or near the sources, minimizing energy consumption & facilitating easier water reuse.
Scalability
Centralised sewage treatment plants are designed keeping in mind current or future population requirements. Though it is crucial to understand that in the case of rapid population modification of centralised STP systems can be challenging given costs & time constraints. Decentralised wastewater treatment systems are more flexible and scalable to meet the demand of a growing population.
Choosing the Right STP Solution
Before making a decision about an STP system, businesses can take the following factors into consideration:
- Available Space: Does your facility have access to a centralised sewage treatment system, or is a decentralised system practical & efficient?
- Costs: Does the initial investment of the chosen STP system and ongoing maintenance costs in your budget?
- Sustainability Goals: Is your focus on water reuse, energy efficiency and sustainable water treatment methods?
- Regulatory Compliance: Are you familiar with local wastewater treatment regulations and the legal obligations?
- Scalability: Will the chosen STP system be able to manage future wastewater requirements?
