Expert Expresses Concern about Wastewater Treatment
“Water treatment is not something you can do anyhow because at the end of the day, it can be deadly,” Co-ordinator, Lagos State Wastewater Treatment & Management Office, Engineer Odukoya remarked on Wednesday, October 28, 2015, at the Civil Engineering Department’s first Town & Gown interaction for the session. In his presentation titled, “Wastewater Treatment System,” Engineer Odukoya explained the factors that influence the design and maintenance of wastewater treatment plants and the process of treating wastewater.
Engineer Odukoya remarked that we are provided with fresh water, but many people fail to consider what happens to it after it has been used and becomes wastewater. He defined wastewater as water from households, hotels, fast food restaurants, schools and high rise buildings. It includes water from kitchens, bathrooms and laundries and may contain faecal matter and urine.
Engineer Odukoya explained that the method of using septic tanks rather than sending waste water to a treatment facility has caused many health problems due to the seepage of wastewater into the freshwater bed. The effect of this has been an increase in dysentery, typhoid fever and cholera; it can also lead to the pollution of aquatic life. Treating the wastewater in a treatment plant however, is a much safer and environmentally friendly option.
He explained the factors that need to be considered in the design of treatment facilities, which include the population equivalent, hydraulic loading, the type of wastewater treatment plant and the soil type. In addition, he explained the detailed approach to maintaining wastewater treatment facilities.
The Head of Civil Engineering Department, Dr Olukanni David, in his remarks, thanked Engineer Odukoya for his enlightening presentation, stating that the Town & Gown interaction is an opportunity to see what is happening in the industry and to match it with what is happening in the classroom. He emphasised the need for industries to have confidence in quality of graduates produced by Nigerian universities. In doing so, companies will not have to source employees internationally, but will instead be able to employ Nigerians. He also reminded the gathering of grants that are available for research that is focussed on remedying local problems. In concluding, he encouraged students to engage in research by joining some of the University’s research clusters.
Also in attendance were members of the Department of Civil Engineering and a member from the Directorate of Media and Corporate Affairs.
