Operation & Maintenance of the 130,000 m³/d municipal WWTP based on the SBR-process. Ongoing O&M since December 2008 including technical plant adaptation works.

Scope:

WABAG is responsible for the operations, maintenance and repair of the entire plant, including all equipment as well as provision of chemicals and energy.

Ensuring water security and improving sanitation for Delhi through efficient operation and maintenance of drinking water and wastewater treatment plants.

Project Highlights

• Promoting innovative models to enhance efficiency and resource recovery
• 1 Drinking Water Treatment plants (Dwaraka): 220, 000 m³/d
• 3 WWTP (Kondli, Papankalan & Keshopur): 525,000 m³/d
• 1 Sewage Pumping Station (Possangipir): 41,639 m³/d

Co-financed by EU, a stand out reference in terms of reduced area footprint as well as operating expenditure

Project Highlights

• Turn-key construction of large scale WWTP
• Activated sludge process & Anaerobic sludge digestion
• Energy-neutral – 95% self-sufficiency by use of biogas
• One of the largest solar sludge drying units, providing savings in opex
• Energy savings by gravitational flow of wastewater

Kodungaiyur Plant, executed on DBO model, stands as the role model plant in India for “comprehensive sewage treatment” which focuses on resource recovery with the conviction that “Sewage is a resource, not a liability. The plant is equipped with an advanced sludge management process which is capable of producing adequate amount of electricity to run the entire plant.

Project Highlights

• Mechanical/biological WWTP
• Anaerobic sludge treatment & biogas utilization for energy production
• First in India to achieve 90,000 operating hours from a single gas engine
• Enables reuse of treated water in nearby refinery

A resource-protective wastewater treatment plant for the city of Tehran. The plant is energy-neutral by use of biogas and the purified water is reused for agricultural irrigation. The plant, which covers 4 water lines & 6 sludge treatment lines, was built on DBO-scheme and was operated by WABAG for a period of 3.5 years.

Project Highlights

• Turn-key construction of one of the large scale WWTP
• Activated sludge process & Anaerobic sludge digestion
• Energy-neutral – >80% self-sufficiency by use of biogas
• Process design enables water reuse for agricultural irrigation

Turnkey plant with advanced technology for anaerobic sludge treatment and biogas utilisation for one of China’s largest municipal wastewater treatment plants. The plant produces 67,000 kWh/d.

Project Highlights

• Sludge storage tanks for primary and excess sludge
• Thickening
• Anaerobic sludge digestion
• Dewatering
• P-removal system for sludge dewatering
• Biogas treatment and storage system
