GWERU City Council is establishing environment friendly methods of waste water management as part of its comprehensive plan on climate change strategies, a senior official has revealed.
City engineer Rabson Manatsa said council had refurbished Cambridgeshire plant to use low-cost and environmental friendly waste water treatment methods.
The plant, now 70% complete, was rehabilitated with an estimated US$80 000 grant from the German Agency for International Co-operation (GIZ).
“At Cambridgeshire plant we use simple methods where water is filtered to the now rehabilitated two sewage ponds and we are working on the third pond although progress is slow because of financial constraints,” Manatsa told Southern Eye recently.
“We are targeting to rehabilitate our sewage treatment plants using cost-effective and environment friendly waste water management methods as part of our climate change strategies.”
Manatsa said filtering and aerating waste water using natural biological methods ensures low emission of greenhouse gases into the atmosphere. He appealed to partners to help in the ambitious project as the city required close to US$500 000 to complete the refurbishment of pump stations, sprinklers and filters among other equipment at the sewage treatment plants. Manatsa said council had long-term plans to use treated sewage effluent to irrigate crops.
He said the eco-friendly waste water management methods would also ensure drastic reduction of pollution in down-stream water bodies.
