Selama ini pengolahan lumpur tinja penduduk Kota Merauke hanya memakai tangki septik, padahal Kota Merauke mempunyai air tanah yang dangkal. Dengan demikian sistem tangki septik tidak cocok diterapkan karena peresapannya tidak akan berfungsi dengan baik dan akan membuat tangki menjadi cepat penuh sebelum waktunya. Untuk itu ketersediaan Instalasi Pengolahan Lumpur Tinja (IPLT) di Kota Merauke merupakan hal yang sangat mendesak. Dalam merencanakan bangunan pengolah limbah tinja, terdapat beberapa dasar-dasar perencanaan yang harus diperhatikan terutama yang berkaitan dengan kuantitas buangan tinja yang dipengaruhi oleh jumlah penduduk yang dilayani, dan jumlah fasilitas kota. Alternatif pengolahan lumpur tinja pada kota Merauke terdiri dari imhoff tank,kolam stabilisasi (yang terdiri dari kolam anaerobik, kolam fakultatif, kolam pematangan) dan sludge drying bed . Dari hasil perhitungan, jumlah dan dimensi dari masing-masing unit antara lain: 1)Imhoff tank: Jumlah tangki 1 buah yang terdiri dari 4 kompartemen, dengan panjang 6,5 meter, lebar 2,5 m, dan kedalaman 5,65 meter. 2)Kolam anaerobik: Jumlah kolam 2 buah, dengan panjang 8 meter, lebar 4 meter, dan kedalaman total 3,5 meter. 3)Kolam fakultatif:Jumlah kolam 2 buah, dengan panjang kolam 19 meter, lebar kolam 9,5 meter, dan kedalaman total 2 meter. 4)Kolam Pematangan: Jumlah kolam 2 buah, dengan panjang 18 meter, lebar 9 meter, dan kedalaman total 1,5 meter. 5)Sludge Drying Bed: Jumlah bak 3 bak masing-masing terdiri dari 10 bed, dengan panjang bed 10 meter, lebar bed 4 meter, dan kedalaman total 1,325 meter. Sedangkan estimasi dana yang dibutuhkan untuk pembangunan IPLT ini kurang lebih sebesar Rp. 3.499.185.392,00

Alt. Description

Until this time being, sewage treatment existed in Merauke is only a septic tank. Whereas, for area which has superficial ground water level like Merauke, it is not recommended to use a septic tank system because the absorption mechanism will not happen well and then will cause an overload problem earlier than it should be. Hence, sewage treatment plant (STP) in Merauke is a real need. In the planning of STP, there are basics of planning that have to be concerned especially the one related to the quantity of the septage which is affected by population served and facility of the town. Alternatives of STP in Merauke consist of imhoff tank, stabilization pond (consist of anaerobic pond, facultative pond and maturation pond), and sludge drying bed. Based on the calculation, dimension and quantity of each unit are: 1)Imhoff tank, quantity: 1 unit, consist of 4 compartments with length 6,5 meter, width 2,5 meter and depth 5,65 meter, 2)Anaerobic pond, quantity: 2 unit with length 8 meter, width 4 meter and total depth 3,5 meter, 3)Facultative pond, quantity: 2 unit with length 19 meter, width 9,5 meter and total depth 2 meter, 4)Maturation pond, quantity: 2 units with length 18 meter, width 9 meter and total depth 1,5 meter, 5)Sludge drying bed, quantity: 3 units each consist of 10 beds with length 10 meter, width 4 meter and total depth 1,325 meter. While, budget estimated for construction of STP is about Rp. 3.499.185.392,00
