Serang City's Perumdam Tirta Madani Establishes Partnership with PT Jaya Dinasty Indonesia
SERANG CITY – Following the signing of a cooperation agreement between Perumdam Tirag Madani and PT Jaya Dinasty Indonesia (JDI) regarding bulk water sales, the Serang City Regional Secretary, Nanang Saefudin, expressed full support for this progressive step. He noted that this pure Business-to-Business (B2B) partnership demonstrates Serang City’s readiness to facilitate incoming investment waves, particularly within the industrial zones of the Kasemen District.
The local government emphasised that the arrival of investors must be accompanied by the readiness of crucial infrastructure. Nanang stated that industrial operational needs in the Kasemen area are projected to require a clean water supply of up to 60 litres per second. The Serang City Government views this as a strategic opportunity to be facilitated by regional-owned enterprises (BUMD) to prevent industries from seeking alternative sources that could damage the environment.
“As an industrial area, infrastructure—specifically water supply—is crucial for any company. We cannot simply say we are ready to receive external investment without preparing the necessary facilities. This is where the local government steps in to facilitate through Perumdam Tirta Madani,” Saefudin asserted.
He further explained that the partnership represents a symbiotic relationship: PT JDI gains certainty in the supply of industrial-standard clean water, while Perumdam Tirta Madani, as a BUMD, gains potential profit and asset optimisation, which will contribute to the Regional Original Income (PAD) to fund city development.
Beyond economic aspects, the policy of supplying water to industry via Perumdam Tirta Madani carries an important ecological mission. It is well known that groundwater quality in parts of Kasemen is suboptimal, often described locally as ‘Anta’ (brackish). By diverting industrial needs to surface water (river water) professionally treated by Perumdam, the local government aims to mitigate two issues: preventing environmental damage caused by massive groundwater exploitation—which can exacerbate land subsidence—and protecting residents’ consumption by ensuring local wells are not affected by saltwater intrusion.
On a macro level, this B2B collaboration is part of a larger strategy by the Serang City Government to optimise regional governance, particularly in infrastructure development. Regarding the specific details of investment value and revenue sharing, the local government has delegated the technical and operational calculations entirely to the Director of Perumdam Tirta Madani to ensure they are handled rigorously and accountably.
The Director of Perumdam Tirta Madani, M. Arif Setiawan, revealed that the company is set to begin the water supply project for the industrial sector immediately. This strategic collaboration is projected to gradually increase regional revenue by billions of rupiah. The commercial project is designed to align with industrial construction phases and real-time needs. Arif detailed that in the first three months, Tirta Madani will supply a minimum of 500 cubic metres of water per month. At a rate of Rp7,000 per cubic metre, the company targets an initial monthly revenue of approximately Rp35 million. From the fourth month onwards, supply volumes are expected to rise sharply to around 2,500 cubic metres per month.
Looking ahead, the five-year strategic plan aims for a total supply capacity of 60 litres per second. “If we reach a planned supply of 10,000 cubic metres per month, we could generate nearly Rp1 billion from these sales. Everything is moving in stages according to industrial demand,” Arif added optimistically.
Arif Setiawan also addressed concerns regarding water availability for residents, assuring that the operations at the Banten Water Treatment Plant (WTP) are more than capable. Currently, the WTP has a design capacity of 40 L/s, while the existing demand to cover 2,000 household connections uses only 10 L/s. “The community does not need to worry; existing services are fully covered. We still have an idle capacity of approximately 20 L/s. This surplus will be optimised to supply PT JDI. The water used is surface water treated hygienically, not groundwater pumped from residents’ wells,” he clarified.
