Plant Rehabilitation
Wastewater treatment plants frequently suffer from mechanical degradation, biological imbalance, or capacity deficits caused by changing operating conditions over time. Grupo Eleven Solutions® provides specialized services in plant rehabilitation, commissioning, and stabilization for existing clean and wastewater systems across Mexico. Our experienced engineering team performs deep technical diagnostics to restore peak removal efficiency, extend infrastructure lifespan, and ensure strict alignment with environmental effluent quality regulations.
Backed by over 10 years of industrial experience and accredited under ISO 9001:2015 and ISO 14001:2015 standards, we execute turnaround works with minimal operational disruption. Having successfully completed more than 1,200 projects and equipped with 7 regional branches across the country, we represent over 20 exclusive equipment brands, delivering top-tier diffusers, pumps, instrumentation, and dewatering equipment for continuous biological and physicochemical plant revamping.
Full-scale technical rehabilitation and biological stabilization
Wastewater treatment plant rehabilitation is an engineering-driven intervention designed to restore underperforming or aging assets to optimal design specifications or upgraded capacities. The process involves inspecting concrete basins, retrofitting corroded pipework, replacing inefficient blowers and aeration grids, and re-engineering clarifier drives and chemical dosing lines with resilient, industrial-grade components designed to withstand severe process conditions.
Beyond civil and electromechanical repairs, our service addresses system commissioning and long-term process stabilization. This encompasses controlled biological inoculation, biological kinetics monitoring, analytical instrumentation calibration, and automated control integration. By tuning return activated sludge ratios and hydraulic retention times, we ensure the biological ecosystem recovers rapidly, delivering reliable pollutant reduction, odor abatement, and steady operational continuity.

Frequently asked questions
What are the clear signs that an existing WWTP needs rehabilitation?
Frequent mechanical breakdowns, persistent foul odors, excessive sludge generation, turbid effluent discharges, elevated energy costs, and recurrent non-compliance with environmental discharge regulations indicate that critical electromechanical and biological systems require professional rehabilitation.
Can rehabilitation works proceed without shutting down the facility?
Yes. We engineer phased intervention schedules, temporary bypass pumping, and modular basin isolations. This enables major mechanical overhauls, aeration upgrades, and basin cleaning while maintaining partial treatment capacity and mitigating operational shutdowns.
How is biological process stabilization verified after commissioning?
We analyze parameters such as mixed liquor suspended solids (MLSS), sludge volume index (SVI), dissolved oxygen profiles, and microscopic bioindicators to ensure the microbial community is robust, settleable, and actively degrading target organic contaminants.
What qualifications support Grupo Eleven Solutions® in plant overhauls?
We bring over a decade of engineering experience, dual ISO 9001:2015 and ISO 14001:2015 certifications, more than 1,200 successfully completed projects, 7 national branches, and over 5,000 units of specialized equipment supplied nationwide.
