	=== Durability ===		=== Durability ===
			This System is Virtually unlimited in durability.

	=== Microplastics ===		=== Microplastics ===
			Water in this system has no microplastics.

	=== Susceptibility to problems and repairability ===		=== Susceptibility to problems and repairability ===
			This system has problems with plant roots growing through the clay layer.

	=== Water conservation ===		=== Water conservation ===
			In this system, Pond surface area is largest, as the slope angle for the gravel layer must be even shallower. Consequently, evaporation is highest. There is also an Additional water loss due to lack of capillary break (geotextile).

	=== Impact on water quality ===		=== Impact on water quality ===
			In this system, the leaching of nutrients from clay and the covering layer is significant, resulting in rapid algal blooms.

	=== Miscellaneous ===		=== Miscellaneous ===
			No underground extraction and purification possible in this system.

	=== Cost ===		=== Cost ===
			This system is the most expensive of all presented: there is significantly more excavation required, a larger waterproofing surface area and higher delivery costs to be careful of.

			This system also has significantly more complex installation, which can also increase the cost.

1st System

New page

== 1.Geo fleece, LDPE and Wall protection ==

=== Life Cycle Assessment – Initial Setup ===
LDPE is very thin, there is an outgassing of methane and ethylene upon exposure to sunlight and material supply is the least energy-intensive.

=== Durability ===
This system can last around 20 years and the recycling is easier than with only LDPE.

=== Microplastics ===
This system has the most negative impact on the microplastics in the water than all the other systems presented on this page.

=== Susceptibility to problems and repairability ===
This System can still be welded even after 20 years.

=== Water conservation ===
This system has the best water conservation of all the systems presented here. On the EduFarm field it would only have a surface of 1100m².

=== Impact on water quality ===
This system has the most positive impact on water quality of all the presented systems: no leaching of nutrients, and easy to clean.

=== Miscellaneous ===
In this system, underground extraction and purification are possible.

=== Cost ===
The most cost-effective option, although the liner may need to be replaced sooner than with EPDM.
