Around 85% of NPI water tanks are complemented with a cover. These include the ENPI airfloat covers, tensioned anti-algae covers, and galvanized steel roofs. A decent water storage system is the foundation of water management, but the importance of an adequate cover shouldn’t be overlooked! This makes total sense because without a cover in place, significant water loss occurs due to evaporation, and algae growth affects water quality and can lead to problems in the irrigation system.
One of the most sold covers from the company is the tensioned anti-algae cover. These tensioned anti-algae covers are made from 210 gr woven polypropylene with a reinforced edge and stainless steel eyelets. To secure the cover, it is attached to the exterior of the tank or an external supporting system using special hooks and nylon cords. The primary function of this cover is to inhibit the growth of algae while additionally serving to shield the water from contamination by small debris and reduce water evaporation. The woven design allows water to permeate through the cover.
The tensioned anti-algae covers are most suitable for tanks with a diameter of up to approximately 9 meters. For larger diameters, we recommend installing a reinforcement ring in the upper ring, combined with a center pole.
Autumn is coming up, and it is time to remove and inspect your anti-algae cover. Make sure that the anti-algae cover is still intact: are there no tears in the fabric? Is the cord still in order?
In autumn, the influence of the sun gets reduced, and the temperature drops, resulting in less algae growth. On the other hand, this time of year also sees an increased likelihood of wind. Leaves and debris may cause a reduced permeability of the cover during rain showers, causing higher pressure on the cover and the tank walls. So do possible snow loads. The potential for heavy weather conditions brings risks of damage to both the cover and water tank.
Store your anti-algae cover
When autumn starts, it is time to remove your anti-algae cover, give it a thorough cleaning, and store it until spring, when you can reinstall it.
