KAJIAN PENANGGULANGAN LIMPASAN PERMUKAAN DENGAN MENGGUNAKAN SUMUR RESAPAN (STUDI KASUS DI DI DAERAH PERUMNAS MADE KABUPATEN LAMONGAN)

Abstract

Desa Donowarih memiliki manajemen penanganan sampah yang buruk, maka perencanaan
TPPopulation growth and rapid development led to changes in land use functions. Lots of land
which was originally in the form of open land or forest to residential and industrial area. It is not
only urban region, but has been extended in the cultivation and protected areas, which serve a
water. The impact of land use change surface runoff is rising at the same time decresing infiltration
of water into the ground. As a result the area occurs the reduced flood and infiltration into the
ground as ground water augmentation. The same thing happened in the Perumnas Made frequent
during the rainy season puddles. To prevent this and also to maintain the required reserves of
ground water wells.
This study aims to reduce runoff and prevent surface runoff and can increase the potential for
ground water. Besides, in order to take advantage of rainwater into the ground through wells. So
that treatment can conserve and save water resources for long-term soil.
Building design of water infiltration in this study is the recharge wells. Wells can accommodate
surface runoff and rain fall on every house gutters. Recharge wells in this study is planned in each
home. Analysis results obtained from the total volume of rainfall with a 2-year return period is =
2627.468 m3 while total volume of well is 3022.5 m3. As in every home is planned the wells with
circle radius from 0.45 to 0.75 meters with a variation to the depths of the wells ranged from 1.6 m
- 2.9 m. So the wells is very effective to hold the entire discharge with a 2-year return period.

Key words: Pond, Recharge Wells
