Perencanaan Sistem Penyaluran Air Buangan Domestik Sistem Terpusat Kelurahan Belian Kota Batam Provinsi Kepulauan Riau

Abstract

Perencanaan ini bertujuan untuk merencanakan sistem penyaluran air buangan domestik di Kelurahan Belian, Kecamatan Batam Kota, Kota Batam. Diperlukan data primer berupa observasi lapangan dan data sekunder berupa data kependudukan, data kebutuhan air bersih, masterplan wastewater Kota Batam, peta administrasi dan peta kontur. Sistem penyaluran air buangan domestik sanitasi terpusat (off-site system) dengan metode penyaluran terpisah yang akan diolah di Instalasi Pengolahan Air Limbah sebelum dibuang ke badan air penerima. Metode ini dipilih karena air buangan domestik dan air hujan dialirkan secara terpisah melalui saluran yang berbeda serta operasi dan pemeliharaannya cukup mudah. Hasil dari perencanaan ini berupa desain teknis Sistem Perencanaan Air Limbah (SPAL). SPAL Kelurahan Belian melayani sebanyak 89790 jiwa pada tahun proyeksi 2025 dengan debit air buangan rata-rata 15.264,3 m3/hari. Dimensi pipa yang digunakan mulai dari 200mm – 1000mm. Sistem ini dilengkapi dengan manhole, drop manole dan 5 stasiun pompa. Pipa yang digunakan terdiri atas 3 jenis yaitu pipa uPVC untuk pipa sekunder (gravitasi) D200-D250mm. Pipa GRP pipa sekunder (gravitasi) D300-D500mm, pipa primer D200-D1000mm. Pipa DCIP hanya digunakan untuk pipa pressure. Dari hasil perencanaan ini diharapkan dapat mengurangi pencemaran lingkungan dan menciptakan kawasan yang bersih dan nyaman.

The purpose of this planning is to plan a domestic wastewater sewer system in Belian Sub-District, District of Batam Kota, Batam City. Primary data is needed in the form of field observations and secondary data in the form of population data, data on clean water needs, wastewater masterplan of Batam City, administration maps and contour maps. The domestic wastewater distribution system is centralized (off-site system) with a separate distribution method that will be processed at the Wastewater Treatment Plant before being discharged to the receiving water body. This method is chosen because domestic wastewater and rain water are channeled separately through different channels and the operation and maintenance are quite easy. The results of this plan are in the form of a engineering design of the Wastewater Treatment Plant (WWTP). SPAL Belian Sub-District serves as many as 89790 people in the projected year of 2025 with average wastewater demand as much as 15.264,3 m3/day. The pipe dimensions used start from 200mm to 1000mm. This system is equipped with manhole, drop manhole and 5 pump stations. The pipe used consists of 3 types, namely uPVC for secondary pipe (gravity) D200-D250mm. GRP for Secondary (gravity) D300-D500mm, D200-D1000mm primary pipe. The DCIP is only used for pressure pipes. From the results of this planning, it is expected to reduce environmental pollution and create a clean and comfortable area.
