Waste management is an activity that people have been dealing with since ancient times. In today's time, the goal is to stimulate an economy that would function circularly and in which the usefulness of materials and resources would be maintained. Circular management implies the creation of raw materials of an industry from the waste of the same or another industry. In order for such a cycle to be possible, there are a number of requirements and technologies that must be implemented. Waste disposal involves the process of decomposition of organic substances that emit landfill gas and, in contact with water, creates leachate for which a special drainage system is built so that the environment remains ecologically preserved. The landfill consists of parts of a cover soil layer, a protective clay layer, a stormwater drainage layer, a degassing layer, a waste layer, and an underlying protective layer consisting of a geomembrane and a seepage control layer. It is important to adhere to the layout of the landfill, respecting the requirements regarding access roads and access to the landfill itself. When designing a drainage system, data on seepage water (amount of flow and hydrological features) and design equations are important, from which, assuming the speed of water flow through the pipes, we get the size (diameter) and distance of the corresponding collection and main drainage pipes. Dimensioning the drainage system is one of the main projects that helps prevent long-term environmental pollution.
