EcoTec EcoSBR™ – Safe, Reliable & Future-Ready Sewage Treatment
At EcoTec Engineers and Consultants, we believe sewage treatment plants must be designed as long-term infrastructure assets, not short-term compliance installations. Since 2011, EcoTec has been designing and delivering sewage treatment plants customised to the specific requirements of different building types, earning recognition across the water sector for engineering-led solutions that prioritise reliability, safety, and lifecycle performance.
With over 1,500 installations and a Presence across 16 countries, EcoTec brings proven field experience to every project—spanning residential developments, commercial buildings, institutional campuses, and decentralised urban infrastructure.
EcoSBR™ is EcoTec’s flagship sewage treatment solution—an advanced engineering adaptation of Sequencing Batch Reactor (SBR) technology—developed to address the real-world challenges of wastewater treatment in diverse operating environments. The EcoSBR series reflects EcoTec’s focus on process stability, operator safety, and treated water reuse, rather than one-size-fits-all designs.
Designed specifically for Indian sewage characteristics and decentralised infrastructure conditions, EcoSBR performs reliably under variable flows, fluctuating organic loads, and phased occupancy scenarios. This makes it particularly well suited for residential and mixed-use developments where consistency, safety, and ease of operation are critical.
Unlike conventional STPs that often fail due to BOQ-driven design, over-complex systems, and poor operability, EcoSBR follows a process-driven, safety-first engineering philosophy. Its single-reactor, multi-function configuration reduces mechanical complexity, footprint, and energy consumption while improving biological treatment efficiency and operational reliability.
Safety is embedded into EcoSBR from the very beginning—starting with site identification and layout planning, and extending through design, construction, operation, and long-term maintenance. By minimising confined-space exposure, reducing manual intervention, and ensuring predictable process control, EcoSBR creates treatment plants that are safe to operate and stable over time. EcoTec firmly believes that safe operation is the foundation of community safety, particularly in residential and mixed-use environments.
With strong engineering expertise in decentralised wastewater treatment systems, EcoTec designs EcoSBR to combine efficiency, simplicity, and user-friendliness. Available in packaged, modular, and site-built configurations, EcoSBR ensures low and predictable operating costs, making it commercially practical for long-term ownership.
EcoTec EcoSBR™ transforms sewage treatment from a regulatory necessity into a dependable, safe, and efficient water infrastructure system—engineered to perform reliably for decades.
EcoSBR TREATMENT PROCESS
The EcoSBR sewage treatment system is designed to treat wastewater in a series of distinct batches. The treatment happens in four key operational phases within the SBR's aeration chamber:
Filling: Raw wastewater is fed into the aeration chamber, initiating the treatment cycle.
Aeration: Biological treatment takes place as oxygen is introduced into the chamber. This phase also incorporates anoxic and anaerobic conditions as needed to enhance nutrient removal.
Sedimentation / Settling: The aeration is stopped, allowing the activated sludge to settle to the bottom. This process results in a clear, treated water zone at the top of the reactor.
Clear Water Removal: The clear water is removed for further tertiary treatment or disposal. Following this, a controlled amount of excess sludge is removed from the bottom of the reactor.
The number of treatment batches per day can vary from 3 to 6 cycles, depending on site specific requirements. For larger capacities, multiple reactor modules can be integrated into a single treatment plant.
