CTG Capital, a subsidiary of CTG Clean Technologies Group Ltd. in Peru, will provide two districts of the city of Lima – Callao and Miraflores – with local wastewater treatment plants (WWTP). These projects will reduce groundwater pollution and the treated effluent will be used to irrigate municipal landscaping.
Peru is suffering from a sever water shortage and has a limited water and waste water infrastructure and water recover is central to national goals for the successful implementation of a national water usage program.
Water production on the Callao plant will start in late August 2010 and will extend over an area of 4,000 m2. The processed water will be used for irrigation of municipal parks.
The Maria Reiche Garden in Miraflores – named in honor of the famous archeologist who studied the famous Nazca shapes – overlooks the Pacific Ocean. It presently has an obsolete treatment and irrigation system that fails to meet municipal pollution requirements. The technology which will be implemented by CTG Capital in the WWTP will eliminate contamination in the water and ensure a continuous supply of clean water to irrigate the park.
The Callao plant will have a capacity of 1200 m3/day and, in a second stage of the project, the capacity will be increased to 4000 m3/day in three new installations. In Maria Reiche, the flow rate will be 600 m3/day, during the first stage, and that could be increased to 1200 m3/day to cover the Miraflores needs.
In these projects CTG will provide complete Build-Operate-Transfer (BOT) programs by which CTG Capital will supply and operate these projects for a period of 30 years. The project will be implemented using aerobic MBBR technology supplied by Aqwise.
The City of Lima has discussed the possibility of increasing the number of WWTPs supplied by CTG Capital to as many as five in order to cover all green areas in the city.
