Ground water potential for supplemental irrigation for new rice growing areas in Bertam

K. Sani and M. Azuhan

Abstract

Ground water potential for MARDI Station at Bertam was evaluated in this study and the results of hydrogeological analysis have indicated poor ground water potential. Yields from wells MB 1A and MB 2 are only about 3-4 L/s with specific capacity of 0.2 L/s per metre and with an average transmissivity of only 20 m²/day. Pumping time to operate these wells was limited not to exceed 6 h/ day. Other boreholes. MB l . MB 3 and MB 4 had to be abandoned because of poor yield or poor ground water quality. Ground water from MB 3 was found to be of high salinity level thus it is unsuitable for crop irrigation. Eventhough the discharge capacity of the viable wells could not meet the demand for padi irrigation. it can certainly be used to supply water to fruit orchards and vegetable farms.
