Can Mechelen’s extended Keerdok season and a new Nekkerpool end its swimming shortage?
Mechelen will keep its Keerdok open-water zone operating until 30 September 2026 and is exploring a full additional pool at De Nekker, while four neighbourhood pools are scheduled to open progressively from mid-September, subject to provincial permits.
The decisions affect whether Mechelen’s children can receive swimming instruction, clubs can maintain training schedules and residents can find affordable public swimming space after the loss of the city’s old municipal pool.
has extended the 2026 swimming season at the until 30 September and opened a market consultation for a full additional pool at , as the Flemish city tries to restore capacity lost when its ageing pool closed on 30 June. Mayor Bart Somers and sports alderman Abdrahman Labsir, both of Voor Mechelen, presented the measures alongside four covered neighbourhood pools that are due to open progressively from mid-September, once the grants the necessary permits.
For residents, schools and swimming clubs, the immediate issue is access rather than architectural ambition. Since closed, swimmers have depended largely on the existing and the seasonal zone. Het Nieuwsblad reports that the new Swimwise units will be located in Hombeek, Otterbeek, at Winketkaai and beside the former Geerdegemvaart facility. Three will accommodate up to 49 swimmers; the double unit at Geerdegemvaart will have capacity for 98, according to the city’s swimming-water plan.
The units are heated, wheelchair-accessible 25-metre pools intended primarily for lessons, schools, clubs and lane swimming. The city says schools and clubs will retain their allocated hours through a combination of these pools, and an agreement allowing clubs to use the Sint-Romboutscollege pool outside school hours. Existing passes are already accepted at Nekkerpool, an important practical bridge for regular users.
The extension gives recreational swimmers another few weeks outdoors: its planned closing date was 6 September. Any further extension will still depend on weather, water temperature and water quality. That qualification matters. Flemish swimming-water monitoring recorded cyanobacteria at Keerdok on 24 July and imposed a swimming ban, after earlier July samples had been rated very good. The city subsequently advertised the zone as open through 6 September, but swimmers must continue checking the flag and current status before entering the water. Some hours operate without a lifeguard, with users responsible for following the safety rules.
’s longer-term answer is taking shape at . The city is preparing to assume control of the provincially managed on 1 January 2027 and says its market consultation has attracted substantial interest. Labsir told Het Nieuwsblad that the responses will help determine the project model and required budget. Somers said the intention is not simply to add a few lanes but to create another complete pool, potentially with private partners. The city is aiming for an opening before the end of the municipal term in 2030, although no design, financing agreement or construction contract has yet been approved.
This mixed approach reflects a problem extending beyond : conventional pools are expensive to construct, heat and staff, while schools and clubs require dependable year-round water. Mechelen’s administration frames modular pools, open water and a possible public-private project as complementary tools. Somers says swimming already absorbs a quarter of the city’s sports budget. The four neighbourhood installations are therefore more than emergency containers in the city’s account: they are distributed local infrastructure contracted for six or, at some locations, fifteen years.
The N-VA opposition shares the diagnosis but places greater emphasis on a permanent municipal pool. In earlier reporting after ’s closure, the party argued that the administration should move quickly on a full replacement and create more open-water locations. That position highlights the central political test: temporary capacity may prevent cancelled lessons, but it does not settle who will finance and operate ’s next permanent pool.
The background is a succession of abandoned or unaffordable replacement options. A proposed Plopsaqua complex once intended to replace did not proceed, while the old pool’s foundations, installations and environmental performance had deteriorated. City documents say further repairs would have cost millions without providing a durable solution; renovation would also have required a closure lasting several years.
Attention now turns to the provincial permits for the neighbourhood pools, including objections lodged at Winketkaai, and to the terms of the Nekker market consultation. must still publish firm opening dates, operating timetables and the financial structure for the proposed permanent pool. Until then, the city has a credible bridge across its swimming shortage, but not yet a completed route to the other side.
Impact
Regional — The plan transfers a provincial swimming asset into municipal management and requires the Province of Antwerp to decide permits for the neighbourhood installations. It may also offer a model for other Flemish municipalities facing ageing, energy-intensive pools.
Local — For Mechelen residents, the immediate issue is whether enough usable water will be available for school lessons, swimming clubs and affordable recreational access. The four neighbourhood pools could restore covered 25-metre capacity from mid-September 2026, but their openings depend on permits from the Province of Antwerp. Keerdok offers an extra 24 days of seasonal access, provided safety and water quality allow it. Municipal control of Nekkerpool from January 2027 should give the city more direct responsibility for local provision.
What it means for you
Mechelen swimmers, parents and clubs should watch for the confirmed opening dates of each neighbourhood pool from mid-September 2026, since provincial permits remain outstanding. Keerdok users can plan to swim until 30 September rather than 6 September, but should check the official Flemish water-quality status before travelling because cyanobacteria can trigger an immediate ban. From 1 January 2027, questions about Nekkerpool management should be directed to the city. The additional De Nekker pool is not an immediate option: 2030 is only the current target.
Opposing perspectives
- Voor Mechelen administration
Mayor Bart Somers and sports alderman Abdrahman Labsir present modular neighbourhood pools, an extended Keerdok season and private participation at De Nekker as a pragmatic portfolio: immediate capacity first, followed by a permanent full-sized addition when its financing and operator are known.
- Mechelen N-VA opposition
The N-VA opposition accepts that retaining the worn-out Geerdegemvaart pool is no longer realistic, but argues that the city must move rapidly towards a full permanent municipal pool and create additional open-water locations. Its emphasis is on ensuring temporary units do not become a substitute for a durable public solution.
- Flemish water-safety authorities
The monitoring framework treats open-water access as conditional rather than guaranteed infrastructure: cyanobacteria, bacterial measurements, weather and supervision can interrupt swimming. That safety framing tempers the city’s presentation of Keerdok as dependable extra capacity.
