Drinking water pond

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.

2.Geo fleece, EPDM and Wall protection

Life Cycle Assessment – ​​Initial Setup

This system uses more materials than the LDPE system.

Durability

This System has a longer service life than the LDPE system (approx. 40 years) but has poorer recyclability.

Microplastics

This system has a better impact on microplastics in water than the LPDE system has.

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

Pure film is roughly twice as expensive as LDPE and more complex to install.
