| Summary: | The Regional Public Drinking Water Company Tirta Raharja is the water supply agency for the
Bandung Regency area. According to the Master Plan for the Development of the Drinking Water
System,, Bandung Regency has set a target for drinking water services, with 80% of the distribution
being piped and 20% non-piped. To meet the targets for water access, PDAM Tirta Raharja is
planning the construction of the Kertasari Water Treatment Plant. Kertasari WTP is planned to
serve six districts in Bandung Regency, namely Paseh, Cikancung, Rancaekek, Cicalengka,
Majalaya, and Solokan Jeruk. The construction of IPA Kertasari is planned to be carried out in two
phases, with a capacity of 425 L/s per phase and a total discharge capacity of 850 L/s for a period
of 20 years, from 2024 to 2044. The raw water source used for IPA Kertasari is the Citarum River.
Based on the raw water analysis, there are four parameters that do not meet drinking water quality
standards: total coliform, fecal coliform, Total Dissolved Solids (TDS), and turbidity. To determine
the configuration of the treatment units, the Simple Additive Weighting (SAW) method was used to
select the best alternative. The differences in each alternative lie in the flocculation unit, which
includes mechanical flocculation, hydraulic flocculation, and a combination of mechanical
flocculation and sedimentation (Clearator). The selected treatment unit alternative for IPA
Kertasari is the second alternative, with a configuration consisting of mechanical coagulation with
a curve blade, vertical flow hydraulic flocculation with a baffle channel, sedimentation with a plate
settler, rapid sand filtration with dual media, and disinfection with a chlorine contact tank. The
capital cost required for the construction of IPA Kertasari in the first phase is IDR 23 billion, and
in the second phase is IDR 22 billion. The financial analysis of the first phase shows an NPV < 0
and BCR < 1, indicating that the project is not feasible. However, in the second phase, the NPV >
1 and BCR ? 1, indicating that the project is financially feasible |
