PERENCANAAN DRAINASE BAWAH PERMUKAAN (SUBSURFACE DRAINAGE) STADION GELORA PANATARAN KABUPATEN BLITAR

Gelora Panataran Stadium still does not have a good drainage system, so
that when it rains it will cause puddles that can interfere with activities in the
stadium. So to overcome this problem it is necessary to plan the construction of a
subsurface drainage system. Planning for the subsurface drainage system at the
Gelora Panataran Stadium in Blitar uses a rainfall reference with a 10-year
return period, the design of the soil layer structure is in accordance with FIFA
standards. For the diameter of the results of the analysis, the diameter of the
subsurface geopipe is Ø100 mm with a distance of 2.5 m between the pipes for the
dimensions of the surface drainage which functions as a catchment for runoff
from the subsurface pipe of b = 0.30 m and h = 0.3 m. For complementary
buildings such as a control tub with a size of 1 m x 1.6 m and a storage pool that
has 2 chambers which have a size of 2 m x 2 m outside the stadium.
