Landfill Siting, Closure and Rehabilitation Studies

Saudi Environmental Studies provides landfill siting and closure studies in Saudi Arabia, including rehabilitation studies, for waste owners, operators and developers. We scope, coordinate and manage the environmental study work; the waste engineer, geotechnical and hydrogeological specialists, licensed environmental consultant and laboratories named in your proposal deliver it.

Landfill decisions extend far beyond finding available land or covering the final waste face. Siting must test constraints, pathways, receptors, access and the regulatory route. Closure must address final form, water, gas, settlement, aftercare and future use. Saudi Arabia’s National Center for Waste Management, MWAN, regulates and oversees waste-management activities. The applicable waste activity, licence, facility standard, environmental permit and authority interfaces are checked against current official requirements, and our studies do not replace the licence, approved method or regulatory decision that applies to your project. Landfill engineering design is provided only where a named waste or landfill engineer is appointed for that scope.

Evidence for a landfill siting decision

A siting study first defines the facility concept: waste types and acceptance limits, capacity, footprint, operational life, supporting infrastructure, transport assumptions and long-term land use. Screening then considers land ownership and planning, geology, hydrogeology, flood and drainage, topography, climate, ecology, cultural constraints, aviation or utility interfaces, access and sensitive communities or resources.

Alternatives are evaluated against consistent criteria, with exclusions, data confidence and trade-offs visible. A map is not the decision by itself. Field reconnaissance and specialist investigations may be necessary to confirm desk-study findings. GIS, sensitive-receptor and environmental-constraints mapping can provide a controlled screening base, while the formal permit pathway sits under NCEC environmental permit application support.

Closure starts with a verified facility model

For an existing site, the study assembles waste history, surveyed geometry, remaining capacity, liner and leachate information, gas data, settlement behaviour, drainage, stability, fires or incidents, groundwater and surface-water results, permit conditions and surrounding receptors. Gaps are logged rather than disguised by a generic closure detail.

Closure objectives can include controlling infiltration and runoff, managing leachate and gas, maintaining stability, preventing unauthorised access, reducing erosion and supporting a safe agreed end use. The engineering partner is responsible for cap, drainage, gas, leachate, stability and settlement design. Environmental specialists define the receptor and monitoring basis. A rehabilitation concept must remain compatible with residual risks; landscaping cannot remove subsurface obligations.

The plan sequences:

1. interim cover and final grading;
2. infrastructure modification and construction quality assurance;
3. material acceptance and erosion controls;
4. revegetation where appropriate and transition to aftercare.

If old or uncontrolled waste areas are being assessed, intrusive work needs a hazard-specific safety plan and careful unexpected-finds procedure. Any contaminated land issue is handled through the contaminated-land assessment and remediation-planning service.

Aftercare is part of the closure scope

Monitoring may address groundwater, surface water, leachate, gas, settlement, cap integrity, erosion and vegetation. The parameters, locations, frequency, trigger levels, response actions and duration come from the current approval basis and the engineering design, not from another jurisdiction. Data ownership, access, maintenance, reporting and funding responsibilities should be set before operations cease.

Closure evidence can include as-built surveys, material and quality records, laboratory results, construction photographs, inspection logs, waste and soil tracking, deviations and a residual-risk register. The completion package distinguishes construction completion from regulatory closure or release from obligations; only the competent authority can make the latter determination.

Operational odour monitoring and complaint diagnosis are separate from this formal lifecycle study. They belong to Saudi Odour Monitoring, while Saudi Environmental Studies remains focused on siting, permitting, closure and rehabilitation documentation.

Define the delivery team and decision

Provide the site location and boundary, owner and operator, authority and licence context, waste types, historic and forecast quantities, surveys, designs, monitoring data, incident history, receptor information, proposed end use, schedule and decision required. For a new site, add capacity and transport assumptions plus candidate alternatives. For closure, add remaining operations and planned cessation dates.

Your proposal names the licensed consultant and the responsible waste, civil, geotechnical, hydrogeological, gas, ecology, laboratory and construction-quality parties. It states which outputs are concept study, design input, permit submission or construction documentation.

Landfill siting and closure studies are available for projects across Saudi Arabia, including Dammam, Jubail, Riyadh and Jeddah.

Make landfill siting and closure studies procurement-ready

The brief should distinguish data collection from interpretation and engineering. Survey, drilling, pumping tests, gas monitoring and laboratory schedules need quantities and quality requirements; the responsible specialists then interpret them against the site model. Review gates can cover siting shortlist, investigation design, closure basis, engineering concept and final submission.

Uncertainty should be priced and governed. Legacy sites may have incomplete waste records or inaccessible areas, and a closure design may depend on settlement or gas behaviour that develops over time. The report sets assumptions, contingencies and decision triggers rather than hiding them in a single lump-sum deliverable.
