Absoluut schandalig. Ik heb ook een huishouden, waar blijft mijn vergoeding (ter waarde van meer dan de helft van mijn loon!).
Ondertussen worden mensen op straat gezet die hun facturen niet meer kunnen betalen, dit is echt om te kotsen!!!

They cheated though. it was all flat road, not narrow passes and tricky caves.

The ancient Peruvian Nazca people built underground aqueducts called puquios to combat water scarcity over 2.000 years ago. These systems were constructed between 300 BCE and 500 CE and transported water from aquifers to arid regions.

Dye tracing is a quick and affordable method with no environmental impact. It is an excellent choice for troubleshooting.

Dye tracing makes it possible to visualise the flow paths between different parts of a drainage or sewer system. This is particularly helpful in urban areas where old or unmapped networks can make it difficult to understand how water moves.

We trace water by injecting a small amount of fluorescent dye into a system, which can then be detected visually, or using optical sensors (www.traqua.be/en/technologie). If the dye appears in an unexpected location, this indicates a leak or unintended connection.

Leaks and unknown connections are common in ageing drainage and sewer systems. Fluorescent dye tracing is a powerful, non-invasive method to investigate such underground networks.
