Manifestos, Master Plans and the Missing Ex*****on | Part 6 of 7
Accra has not lacked plans. It has lacked ex*****on at the speed, scale and consistency the flood problem requires. In the earlier parts, we followed the water. We looked at the Odaw–Korle system, the tributaries, the drains, the outfalls, the occupation of flood space, the laws, the wetlands and the Ramsar sites.
Part 6 asks the next question. After decades of knowing the problem, what exactly has Ghana promised to do about Accra’s flooding, and what has actually been delivered? The planning history is not new.
Accra had a drainage master plan as far back as 1963. A later roads-and-drainage study begun around 1990 included revision of that master plan so roadside drains could discharge properly through the city’s main outlets to the sea. That does not mean a 1963 plan should still control modern Accra. It means Ghana has known for decades that Accra’s drainage problem requires planning, engineering and coordination.
Yet decades later, the Auditor-General found that the Hydrological Services Department was still operating without the drainage master plans needed for coordinated flood-control infrastructure. The Ministry and the Department had included preparation of drainage master plans in sector medium-term development plans from 2013, but the audit found they were not prioritised, properly planned or properly budgeted for. That is where the ex*****on gap begins. A plan enters the policy document. It does not always enter the budget. A promise enters the manifesto. It does not always become a completed drain, a retention pond, a maintained channel or a protected waterway.
In the 2016 NPP manifesto, the party promised to construct storm drains in Accra and other cities to deal with recurring floods. It also promised to establish a National Hydrology Authority responsible for drainage, flood-control measures, major dams, sea defence, storm drains, constant dredging and desilting of waterways. That institutional promise was eventually delivered. In 2022, Parliament passed the Ghana Hydrological Authority Act, creating the Ghana Hydrological Authority. The Authority now has responsibility for planning, design, ex*****on, operation and maintenance of flood-control mechanisms, drainage improvement works, coastal engineering and hydrology. Its Drainage Unit is responsible for stormwater drainage planning, drainage master plans, hydraulic analysis, retention structures, rehabilitation and technical support to local authorities. That is progress but creating an institution is not the same as funding the infrastructure it needs to build.
In July 2024, the Works and Housing Minister announced GH¢1.5 million in seed funding for the Ghana Hydrological Fund. At the same event, he said only about 2% of drainage channels in Greater Accra that required concrete lining had been addressed. That one figure says a lot. The Authority exists. The drainage deficit remains much bigger than the resources immediately available to fix it. The clearest numerical evidence comes from the Auditor-General’s performance audit of flood-control works by the Ministry of Works and Housing and the former Hydrological Services Department between 2015 and 2019. More than GH¢117.7 million had been spent on the construction and maintenance of drains and culverts during the period reviewed. The Department targeted 110 kilometres of drains. It delivered 12.2 kilometres. That is about 11% of the target.
The same programme targeted retention ponds for 18 drainage basins. The Auditor-General found that none had been constructed during the audit period. Retention ponds matter because they temporarily hold stormwater upstream and release it after pressure in the downstream drainage system falls. They reduce the volume of water arriving in the main channel at the same time. Without that storage, more water moves faster into drains that may already be narrow, blocked, silted, undersized or surrounded by development. The audit also found that 20 out of 27 sampled drainage projects, representing 74%, experienced delays. One reason was delayed payment to contractors, causing some contractors to suspend work. The audit also found inadequate monitoring and inspection, and reported defects in some completed works.
Then there was maintenance. Completed and existing drains were not properly maintained because maintenance was not prioritised in annual activity plans and budgets. Weeds, silt and debris reduced the ability of drains to carry water. That is a major point. Flood control is not only about building drains. A drain can be built and still fail. A channel can be widened and still lose capacity. A culvert can be installed and still become a bottleneck. Infrastructure without maintenance becomes another flood risk.
Then came GARID. In May 2019, the World Bank approved US$200 million for the Greater Accra Resilient and Integrated Development Project. The first phase focused on the Odaw River Basin and was designed to improve flood-risk management, solid-waste management and infrastructure in vulnerable communities. More than 2.5 million people in the basin were expected to benefit. GARID was not designed as another ordinary desilting exercise. Its flood programme included performance-based dredging of the Odaw and its tributaries, upstream flood-retention basins, sand traps, rehabilitation of major drains, replacement of bridges that obstruct flow, rehabilitation of the Korle Lagoon Interceptor Weir, reconfiguration of the Odaw outlet toward the sea and improvement of a Flood Early Warning System. That is the kind of basin-wide approach Accra needs but GARID also shows how long the distance can be between project approval and physical delivery. The project website described the initial phase as a five-year programme covering 2020 to 2025.
Then COVID-19 intervened. In 2020, US$65 million from GARID’s emergency-response component was triggered for Ghana’s pandemic response. In 2023, the World Bank approved another US$150 million for GARID. The additional financing was needed partly to replace the financing gap created by the COVID response, pay resettlement compensation for about 2,800 project-affected persons, and meet cost increases caused by inflation and additional engineering requirements. So the commonly quoted US$350 million GARID figure needs context.It is the original US$200 million plus US$150 million additional financing. It does not mean US$350 million has already been spent on Accra drains. GARID also covers solid-waste management, community upgrading, institutional measures, resettlement and other components. Part of the original financing was activated for COVID emergency response. That distinction matters because political language often turns commitments into achievements before the public sees the completed infrastructure.
The 2024 NPP manifesto said the government had invested US$350 million in dealing with flooding in the Odaw Basin through GARID. It also said the National Flood Control Programme had constructed 10 kilometres of new drains and lined 36 kilometres of channels. The manifesto promised to strengthen the Ghana Hydrological Authority, enforce land-use controls in drainage basins and use technology, digitisation and artificial intelligence for flood mitigation and early warning.
The 2024 NDC commitments also returned to familiar flood-control tools: water-retention and detention reservoirs in flood-prone communities, improved drainage in Accra and other cities, maintenance of systems including the Odaw, regular desilting by local governments and construction of storm drainage in critical urban areas.
Different parties. Similar vocabulary. Storm drains. Dredging. Desilting. Retention ponds. Detention reservoirs. Early warning. Land-use control. Maintenance. Flood mitigation.
The problem is not that Ghana’s political system does not know what to say as it clearly does. The problem is delivery.
Take the GARID detention ponds. In 2019, upstream flood-retention ponds were already part of the World Bank-approved approach for reducing downstream flooding in the Odaw Basin. In April 2023, the Works and Housing Minister said the technical team was still finalising the design of retention ponds around the Ghana Atomic Energy Commission area. On 27 July 2026, GARID held an Early Market Engagement conference for major infrastructure works. The packages included the Atomic-East Detention Pond at GAEC, estimated at US$22.11 million, and the Atomic-West Detention Pond, estimated at US$20.33 million. The same engagement covered Alajo drainage improvements, reconstruction of the Abbosey Okai Bridge, Nima-Paloma/Odawna drainage works and a sanitary landfill.
That does not mean GARID has done nothing. Performance-based dredging of the Odaw Basin began in February 2024 under a four-year arrangement. Works have proceeded at Achimota-Abofu, Nima-Paloma, Kaneshie and other locations. GARID has also provided grants to 17 Greater Accra assemblies for drain maintenance and solid-waste management, including more than GH¢7 million distributed in 2023 and more than GH¢8 million in 2024.
There is active work but the timing still matters. Seven years after GARID was approved, some of its major flood-storage and drainage works were still moving through market engagement and procurement in mid-2026. COVID diversion, additional financing, resettlement compensation, inflation and engineering revisions explain part of that timeline. They do not erase the timeline.
The Flood Early Warning System tells the same story. GARID identified flood warning as a core intervention from the beginning. In 2022, GARID-supported flood simulations in five Greater Accra municipalities exposed coordination weaknesses, and officials said a Flood Early Warning System was being established. In April 2023, government announced that the design was complete and that a service provider would be engaged for deployment. By December 2023, equipment had been procured for the Ghana Hydrological Authority, Water Resources Commission, Ghana Meteorological Agency and NADMO. In June 2024, government said a service provider had been engaged to set up and operationalise the platform, and that equipment had been installed in various basins. The target was to complete operationalisation before the following rainy season. By February 2026, the Works Minister and the Ghana Hydrological Authority were still publicly discussing the need to strengthen flood-management systems and enhance early-warning mechanisms.
The official record reviewed shows design, procurement, equipment deployment and institutional coordination. It does not clearly show a later official notice confirming that the full Greater Accra Flood Early Warning System had been commissioned and was fully operational. That should not be overstated either way as early warning is not simply a radar/ equipment purchase. It requires GMet data, hydrological monitoring, modelling, communication systems, NADMO response, functioning local disaster committees and a reliable method of getting warnings to people before the water arrives. A warning can reduce loss. It cannot replace drains, retention ponds, protected wetlands, maintained channels and enforcement against building in waterways.
The wider planning system also exists.
NDPC’s Vision 2057 is meant to provide Ghana’s long-term national development framework. Four-year medium-term frameworks are supposed to flow from it, then institutional development plans, annual action plans and budgets. NDPC launched a terminal evaluation of the 2022–2025 Medium-Term National Development Policy Framework to examine implementation, results, challenges and lessons before preparation of the next framework. The 2026–2029 planning framework now guides institutional plans. In September 2025, NDPC approved medium-term plans including those of the Ministry of Works, Housing and Water Resources and the Greater Accra Regional Coordinating Council.
The breakdown is what happens after the document. The Auditor-General showed one part of the failure. A project can appear in a medium-term plan without receiving enough money. A master plan can be proposed without being produced. A drain can be budgeted without funds being released on time. A contractor can mobilise and then suspend work because payment is delayed. A completed drain can exist without a maintenance budget. A retention pond can remain a target without becoming a pond.
GARID shows another part of the difficulty.
Large flood-control projects require designs, procurement, land, compensation, relocation of affected people and utilities, environmental safeguards, engineering revisions and coordination among several ministries, agencies and local governments. That is real but the city also keeps changing while projects are being designed. The World Bank has identified rapid development in flood-risk areas, inadequate and poorly maintained drainage, and solid-waste accumulation in waterways as major drivers of Greater Accra’s flooding.
In June 2026, the Ghana Hydrological Authority said changing rainfall patterns, rapid urbanisation and increasing development pressure are producing flooding even in locations not previously identified as flood-prone. That means government is trying to build against a moving target but government also controls part of that target. It controls permits. It controls zoning. It controls enforcement. It controls public drainage reservations. It controls whether structures in waterways are stopped before completion. That is why engineering alone cannot solve Accra’s flooding.
In March 2025, President John Mahama announced that illegal structures obstructing waterways would be demolished and referred specifically to encroachment on water-retention areas and Ramsar sites. The Works Ministry later said flood control requires coordination among Works, Roads, Local Government, MMDAs and other institutions, because building drains has limited effect where assemblies fail to enforce development control or road projects do not provide functioning drainage. On 24 July 2026, the Presidency announced that a flood-mitigation task force had begun a phased dredging and demolition exercise across Accra.
That is action but it also raises the question running through this entire series. Why must Accra keep returning to emergency dredging, emergency demolition and rainy-season intervention when the planning rules, institutions, engineering proposals and flood maps already exist?
The answer is not one dramatic failure. It is accumulation. Delayed funding. Incomplete infrastructure. Slow procurement. Delayed compensation. Resettlement complications. Weak maintenance. Projects without current master plans. Plans without budgets. Budgets without timely releases. Drains without protection. Wetlands under pressure. Waterways occupied while enforcement waits. Solid waste reducing channel capacity. Multiple agencies sharing one problem. Political promises that are easier to announce in an election cycle than major drainage infrastructure is to complete within one.
Despite the failures, Ghana has made progress. The Ghana Hydrological Authority now exists. GARID is constructing drainage works. Odaw dredging is underway. Assemblies have received drainage-maintenance grants. Flood-warning equipment has been procured and deployed. New storm drains are under construction. Government has created a multi-agency flood task force. Major detention ponds remain in the pipeline. That last sentence however is the problem in miniature. Some of the most important things Accra needs have been “in the pipeline” for years. Manifestos have named them. Master plans have identified them. Audits have demanded them. Engineers have designed them. Development partners have financed them. Ministers have announced them. The missing element has repeatedly been full ex*****on, followed by maintenance and enforcement.
Parts 1 to 5 showed that Accra’s flooding is connected to how the city plans land, protects waterways, maintains drainage, treats wetlands and enforces its own laws.
Part 6 adds the final piece.
Ghana does not have a diagnosis problem. It has an ex*****on problem. Ex*****on means producing the drainage master plan. Funding it. Protecting the land it requires. Building the retention pond. Completing the drain. Maintaining the channel. Operating the warning system. Stopping the illegal structure before occupation. Keeping waste out. Coordinating the agencies. Continuing after the election. Continuing after the ribbon-cutting. Continuing after the rains stop.
That leaves one final question. After the laws, Ramsar protections, manifestos, master plans, audits, World Bank projects, institutions, dredging contracts, retention ponds and early-warning systems, there is nowhere else for responsibility to hide.
Accra must decide whether planning rules the city, or whether development pressure does.
Because water will follow the terrain whether a manifesto is implemented or not.
That is Part 7.
The Hard Truth — Accra Must Choose Between Planning and Flooding.
