Waste treatment plant to generate its own electricity

March 1, 2017, 3:06 p.m.

THE Lavender Hill Faecal and Waste Treatment Plant in Accra will, before the first half of 2017, begin to produce 7,000 cubic meters of biogas daily which can generate 500 KVA.

This will be enough to cater for the electricity needs of the plant which means the plant will no longer depend on power from the national grid.

The plant, which was commissioned November, last year, currently undertakes primary treatment activities, such as screening, primary settling and sludge dewatering of faecal wastes.

The septage treatment plant has secondary treatment stage, which involves anaerobic digestion (UASB), anoxic-oxic digestion and secondary settling.

The Processing Manager of the plant, Mr Eric Amofa, disclosed this to some journalists on a familiarisation tour organised by Zoomlion Ghana Limited.

With a maximum treatment capacity of 2,400 cubic metres per day but will be doing 2,000 cubic metres per day, he stressed, adding that the new plant has a lifespan of 20 years.

Mr Amofa explained that there is a tertiary treatment stage which includes ultra-violet disinfection, biogas utilisation (combined) heat and power.

Also the plant comprises a modern laboratory which will test both the influent and effluent qualities of the water.

The final effluent, he said, will meet the Environmental Protection Agency standards and will also be pumped back into the system for reuse 

The infamous Lavender Hill had served as a dump site for untreated human excreta, which is released into the sea, and the name (Lavender hill) was the name given to the place because of the pungent smell that emanates from the area.

The Lavender Hill Project is a 15 million dollar public private partnership between Zoomlion and the government of Ghana.

Lavender Hill has been used as a dump site for a large proportion of Accra’s septage since the 1970’s.

This practice has had immense effect on the environs adjacent to the beach, with devastating impact on environmental sanitation, hygiene and healthcare.

The team also visited Dredge Masters, a subsidiary of Jospong Group of companies, which is currently dredging site of the Korle Lagoon - an emergency measure to avert floods that have engulfed the city.

The focus is on the upper and lower Korle Lagoon to contain a large volume of water during rain to be able to move it to the sea.

 During the visit to Subah Infosolutions Ghana Limited, an IT and Telecom solutions provider - another subsidiary of Jospong group of companies -  the management of the company gave insight to the media on their activities.
