Pool Facility Features
The Webber Natural Swimming Pool mimics the natural cleaning mechanisms of a pond or lake and is not chlorinated. Potentially sensitive populations such as the very young, elderly, pregnant women and the immunocompromised may have a greater health risk when using the Webber Natural Swimming Pool.
Fabrics NOT Allowed:
Webber Pool uses filters and plants, not chemicals, to cleanse the water
History of Natural Swimming Pools (NSP):
Construction of Webber Natural Swimming Pool
Webber is larger than many European Natural Swimming Pools
How NSPs Work
Group Use Permit: Apply for a permit to reserve a spot for up to 70 people; Fridays only. Application [PDF]
The Webber Natural Swimming Pool is the first public natural swimming pool (NSP) in North America to have a natural filtration system that will use filters and plants in a nearby pond rather than chemicals to treat the water.
Webber Pool consists of two swimming areas (upper and lower pools) and a regeneration basin. NSPs are living systems and do not use chemicals to treat the water; they function more like a stream, lake, or wetland. Webber’s regeneration basin near the pool holds approximately 7,000 aquatic plants rooted in layers of limestone and granite gravel.
Minneapolis Park Board staff monitors water in the Upper pool, Lower pool, and Regeneration Basin for E. coli, Enterococci, and Pseudomonas aeruginosa bacteria at minimum on Monday morning of each week of the official swimming season. Additional sampling is performed on Wednesday and Thursday if needed.
Webber Pool will be held to a combination of current German natural pool standards for E. coli, Enterococci, and Pseudomonas aeruginosa bacteria and EPA beach standards. If a combination of those standards is not met, the pool will close until further testing reveals that levels are within the standards.
Escherichia coli (E. coli) is a surrogate measure, or indicator for fecal contamination in recreational waters. Indicator organisms themselves do not cause illness under normal conditions.
Ideal conditions in Webber NSP include E. Coli levels below 100 mpn. The NSP must close if E. coli levels exceed 410 mpn, or exceed 100 mpn in two consecutive samples.
Enterococci bacteria are another type of indicator of the potential presence of fecal material in water Enterococci are typically not considered harmful to humans, but their presence in the environment may indicate that other disease-causing agents such as viruses, bacteria, and protozoa may also be present. For natural swimming pools, enterococci typically indicates the presence of birds in the regeneration area.
Ideal conditions in Webber NSP include Enterococci levels below 50 mpn. The NSP must close if Enterococci levels exceed 130 mpn, or exceed 50 mpn in two consecutive samples.
Pseudomonas aeruginosa is a bacteria that is found everywhere in the environment, including soil. Its presence in a natural swimming pool typically indicates the presence of excess sediment in the pool system, indicating that maintenance must be increased.
Ideal conditions in Webber NSP include Pseudomonas levels below 10 mpn. The NSP must close if Pseudomonas levels are above 100 mpn, or if test results exceed 10mpn in two consecutive samples.
Elevated bacteria levels generally occur in NSP environments from:
