Water & Environmental Engineering
Sustainable water infrastructure for communities and industry
Overview
Water is infrastructure. Nigeria's water sector — from community water supply and sanitation to coastal structures, jetties, and environmental impact assessments — presents engineering challenges that demand both technical rigour and environmental sensitivity. Envostructs' water and environmental engineering team has delivered jetties for coastal fishing communities, subsoil investigations for waterfront developments, and environmental compliance advice for major infrastructure projects.

Our Process
Environmental Baseline Survey
Assessment of existing environmental conditions: hydrology, drainage patterns, ecological features, community sensitivities.
Impact Assessment
Identification and assessment of project impacts on water resources, land, air quality, and affected communities.
Design
Engineering design of water infrastructure or environmental mitigation measures to the required standard.
Regulatory Approval
Preparation and submission of environmental documents to NESREA, Lagos SEPA, or relevant state agencies.
Construction & Monitoring
Construction supervision of water or environmental works, with ongoing environmental monitoring and compliance reporting.

View ProjectFrequently Asked
Do you carry out Environmental Impact Assessments?
We support EIA preparation — baseline surveys, impact assessment matrices, and mitigation plans. We work with NESREA-registered EIA practitioners where a full statutory EIA is required.
Can you design jetties and waterfront structures?
Yes. We have designed and constructed jetties in Lagos coastal and inland waterway locations. Our designs account for wave action, tidal variation, boat loading, and fender systems.
What is an Environmental and Social Management Plan (ESMP)?
An ESMP is the document required by the World Bank, AfDB, and many state governments on infrastructure projects — it specifies how environmental and social impacts will be managed during and after construction. We prepare ESMPs to meet international financier requirements.
Do you design drainage systems for residential estates?
Yes. Estate drainage masterplanning — surface water collection, channel sizing, outfall design, and connection to Lagos LASG drainage infrastructure — is a service we provide for developers and estate managers.
