FIELD: construction.
SUBSTANCE: proposed system of filtrate drain from a landfill of solid domestic waste includes a massif of solid domestic wastes 1, under which there is a drainage interbed 2. Below the drainage interbed 2 there is a polymer mesh 3, under which there are perforated pipes 4 at the angles 6. Holes 5 in the perforated pipes 4 are oriented towards the landfill base. Under the perforated pipes 4 there are hydraulically insulated sections 7 covered with a waterproof screen 8.
EFFECT: invention makes it possible to increase time of efficient operation of the filtrate drain system as a result of prevention of the drainage interbed silting.
