This study based on the salt-water shortage in shrimp-pond on the sand coastal area of Dukuh Kuwaru, Desa Ponco Sari, Kecamatan Srandakan, Kabupaten Bantul, Propinsi Daerah Istimewa Yogyakarta which is managed by PT. Indokor Bangun Desa. Proposed solution to overcome this problem is collector well system which expected to supply salt-water adequately. This study conducted to examine the relationship of soil permeability (k), water level (h), and the relationships of collector system [pipe diameter (D), pipe length (L), pipe depth (l), and perforated area (Af)] on discharge of water flow through perforated pipe (Q). The study also reveals the discharge empirical formula resulted from dimension analysis(Q) through perforated pipe on collector well system.

The research being conducted by making physical experiments of collector well system on the laboratory which consists of water basin made from brick work installation and three perforated pipes (total perforated pipes are 27), then filled by sand and water on several variations. Thus, water flow discharge on each perforated pipe measured using calibrated beaker.

Results indicate that several parameters influenced significantly on discharge (Q) are:

Q = f (k, D, L, l, Af, h)

Therefore, empirical formula of collector well system which represents the relationship between Q/k.L.D and Af.h/L.D.l are:

These empirical abbreviations then can be used in order to plan perforated pipe of collector well system.

Keywords: discharge, ground-water flow, perforated pipe, collector-well
