Excessive borehole drilling threatens urban infrastructure

Ini Billie, Uyo

A Regional Planning and Analysis expert, Prof. Jacob Atser, has warned that the uncontrolled drilling of boreholes in urban areas poses serious environmental and infrastructural risks, calling for the adoption of a centralised water supply system in Nigerian cities.

Prof. Atser gave the warning at the weekend while delivering the 125th inaugural lecture of the University of Uyo (UniUyo), where he spoke on the topic “Social Planning in Regional Context: Paradoxical Realities in Nigeria.”

According to him, excessive abstraction of groundwater through indiscriminate borehole drilling in urban centres often leads to land subsidence, which in turn damages public infrastructure such as buildings, roads and pipelines.

“Over-abstraction of groundwater through excessive borehole drilling in urban areas will undermine the sustainability of this vital water source,” he said. “Urban water demand should instead be met through a centralised supply system involving direct reticulation to households.”

Prof. Atser noted that while the drilling of boreholes has increased in response to rising water demand, the environmental consequences—particularly ground sinking—pose long-term dangers to urban development.

He described the development of physical infrastructure as a key strategy for regional growth, noting that such investments attract businesses, stimulate economic activities and promote overall development.

The don also stressed the importance of investing in education, skill acquisition and training, as well as harnessing available urban assets to promote place-based development, which focuses on leveraging local strengths and opportunities.

To address rural-urban disparities, Prof. Atser advocated improved remuneration, attractive allowances and free accommodation as incentives to encourage professionals to work in rural areas.

“Investing in education, skills and healthcare is crucial for development. Improving the knowledge and skills of the local workforce helps attract higher-paying jobs and fosters innovation, while access to healthcare ensures a healthy and productive population,” he said.

He further urged policymakers to focus on the uniqueness of each area, explaining that leveraging cultural heritage, natural resources, tourism potential and existing industries would enhance competitiveness and foster identity and pride among residents.

Prof. Atser also insisted that the financial autonomy of local governments must be protected to ensure effective grassroots development.
