Membentuk Sistem Bersepadu Buangan Efluen di Malaysia: Pengurusan Indah Water Konsortium

Abstract

Theformation of the Indah Water Konsortium (IWK)under an agenda of the National Sewerage System can be seen as a beginning towards a better and modern efluent management in Malaysia. A decade since the formation shows improvement on sewerage service particularly under the Local Authority's area. This paper discusses major roles and problems faced by the IWK in order to enhance the quality of efluent treatment service in Malaysia. These problems were examined critically involving plant treatment aspect, inefficient management system and low level of awareness among the public   to pay for the sewerage service provided. Two types of research methodology used were the questionnaire that involved 104 respondents and laboratory work for Nitrogen ( N ) concentration analysis. Result of the questionnaire indicated that although 86 percent ofthe respondents were knowledgeable of the role of IWK, only 47 percent knew about it in detail. Meanwhile, 44 percent had never settled their sewerage charge while 5 percent of respondents recorded arrears. A total of 13 water samples from Taman Bukit Mewah Phases 5, 6 and 7 sewerage treatments were collected and analysed to identify N concentration. The results indicate that the N value appeared higher during minimum discharge with maximum level recorded was 3.06 mgA and minimum was 0.03 mgA. Meanwhile 11 data recorded values above the Department of Environment standard level (0.9 mgA) at an average of 1.36 mgA.

ABSTRAK

Penubuhan Indah Water Konsortium (IWK) di bawah agenda Sistem Pembentungan Nasional dilihat sebagai titik tolak kepada satu bentuk pengurusan efluen yang lebih baik dan moden di Malaysia. Satu dekad penubuhannya menyaksikan peningkatan perkhidmatan pembentungan terutama di kawasan Pihak Berkuasa Tempatan. Makalah ini membincangkan beberapa peranan dan masalah yang dihadapi oleh IWK dalam usaha meningkatkan mutu perkhidmatan rawatan efluen di Malaysia. Kupasan terhadap masalah-masalah ini mencakupi aspek pengurusan loji rawatan, sistem pengurusan yang tidak cekap dan tahap kesedaran yang rendah di kalangan anggota masyarakat terhadap perlunya membayar perkhidmatan pembentungan yang disediakan. Dua bentuk kaedah penyelidikan digunakan iaitu analisis soal selidik yang melibatkan 104 responden dan analisis konsentrasi Nitrogen (N) di makmal. Hasil soal selidik mendapati walaupun hampir 86 peratus responden mengetahui peranan NK, namun hanya 47 peratus tahu secara terperinci tugas NK, 44 peratus pula tidak pernah menjelaskan caj bayaran pembentungan, manakala 5 peratus responden masih lagi mempunyai tunggakan bil. Sebanyak 13 sampel air efluen dari loji rawatan pembentungan Taman Bukit Mewah Fasa 5.6 dan 7 telah dianalisis bagi menentukan tahap konsentrasi N. Hasil analisis mendapati nilai N adalah tinggi pada waktu luahan rendah dengan nilai maksimum 3.06 mg/l dan minimum 0.03 mg/l. Sejumlah 11 bacaan merekodkan nilai melebihi had piawaian Jabatan Alam Sekitar (0.9 mg/l) pada purata 1.36 mg/l.
