What materials are used to construct your floating aerators?

Clean-Water uses premium, weather-resistant FRP (Fibre Reinforced Plastic) for the floaters, petals, and external housings, supported by structural galvanised frames.

This construction provides buoyancy, corrosion resistance, and structural durability, keeping the unit stable even in turbulent waters and suitable for long-term operation.

Floating aerators are engineered to be low-maintenance, but they are not maintenance-free. The primary routine maintenance activities are:

  • Checking and cleaning the underwater suction screen, generally about once a month or more frequently after heavy monsoon rains, to clear floating plastic debris, twigs, or heavy weed growth that could restrict water intake
  • Inspecting the anchoring system
  • Tightening or loosening the anchoring ropes as required when water levels fluctuate
  • For solar systems, periodically cleaning the panels of dust and bird droppings

During monsoons, water levels may rise significantly, while they can fall during summer. The anchoring system should therefore be inspected and adjusted to maintain the correct operating position.

They are designed to be largely self-sustaining. The primary maintenance involves:

  • Bi-annual biomass harvesting — trimming the top growth of the plants once or twice a year. This is crucial, because cutting away old growth physically removes the trapped nutrients from the lake ecosystem permanently and encourages fresh, vigorous new growth.
  • Debris clearing — occasionally checking the edges for trapped floating trash or plastic bottles carried down by stormwater runoff.

Because the entire system is built on a specialised floating platform, it automatically rises and falls with changing water levels during monsoons or dry spells, ensuring uninterrupted operation regardless of water depth shifts.

The anchoring system keeps the unit within its designated operating area while allowing it to accommodate normal fluctuations. However, extreme weather should still be monitored, and the equipment should be inspected after severe storms or unusually strong water movement.

Yes. Because they float, they simply rise with the floodwaters.

Their flexible anchoring systems are engineered to withstand shifting currents and rising water levels without tearing loose, making them highly resilient compared with static concrete infrastructure.

A fully mature 2 m × 2 m floating wetland typically weighs around 300 to 400 kg, depending on the vegetation and the amount of water retained by the growing media. A significant portion of this weight comes from the structure itself, along with the coco peat, plants, and associated biomass.

However, our floating wetlands are designed with a high buoyancy capacity and are effectively unsinkable under normal operating conditions. The buoyancy does not simply fail because the wetland has matured or become waterlogged.

A 2 m × 2 m island can support more than 800 kg of load before its buoyancy is exceeded. If an exceptionally heavy load causes the island to submerge, some of the coco peat and other loose material may be released, reducing the load and allowing the island to regain buoyancy. Only if a load exceeding its buoyancy capacity is kept permanently on the island could it remain submerged. In such an unlikely situation, the island can be recovered using suitable lifting equipment such as a crane, particularly once water levels have fallen.

In short, our floating wetlands are designed to remain buoyant under normal operating conditions, and sinking would occur only if the designed buoyancy capacity is exceeded.
