SUBSTANCE: invention pertains to land reclamation and may be used for land improvement with blind drainage for the purpose of cultivated grassland and within the period of range utilization. Arrangement method of the drainage system on cultivated grassland including summer camp for cattle, livestock alleyways, and pasture itself presupposes discharge of superficial and filtrated waters from its area into the blind drainage network intake chamber. Drains are laid at a depth making 1.2...1.3 of the standard depth of drains arrangement. Blind drainage crossing area of livestock alleyways and cattle summer camp is made of pipes with waterproof walls. Superficial and filtrated water from the area of livestock alleyways and cattle summer camp is directed through the drainage ditches and open channels arranged on each side of the livestock alleyways and summer camp into the storage pond located in local relief descent.
