"Communal Waste Water Treatment Plant (WWTP) Dusun Tanjung Village" The construction of the communal WWTP is the alignment of Sustainable Development Goals year 2030 in relation to the sustainable economic, environment and social empowerment. The program is an innovative way to empower the community in reducing domestic waste water pollution in Dusun Tanjung so as to improve the healthy lifestyle of the people in Dusun Tanjung.

PTBA also helps the community in applying systematically, integrated and collectively managed domestic waste. Replacing the previous system in which domestic waste was managed by conventional septic tank in every house and some of the waste is directly flowed into the river, the new domestic waste management is healthier for the environment.

PT Bukit Asam Tbk is a pioneer in the construction of communal WWTP for the community with cost-effective way in Dusun Tanjung, in collaboration with the Housing and Settlement Service of Muara Enim Regency. This is more cost-effective because there is no need for annual spending on additional management (draining of waste) in the communal WWTP. The other innovation is the change of WWTP sub-system which operates without a pump to channel domestic waste to the WWTP. The process of channeling the domestic waste is entirely carried out by gravity, this can occur because of the topography and the location of the houses sloping to one point and the location of this point is used as the location of the WWTP.

The sub-system changes can also be seen in the community lifestyle in Dusun Tanjung Village. Prior to the construction of the communal WWTP, the domestic waste management was not standardized. That compelled the company to participate in assisting the government in realizing a better community sanitation.

The program also drives changes in the value chain. In the supplier’s perspective, in case of the community building the communal WWTP independently with funds from the company, the supplier can get additional income and portfolio in the construction of the WWTP. In the company’s perspective as the producer, the program can increase the company image as a company that cares about the environment. In the community’s perspective as the consumer, the community experienced behavioral changes as the awareness of hygiene and domestic waste management increased.

The environmental improvement generated is the reduction of BOD waste up to 94% or as much as 2 tons BOD per year. The program also managed to reduce cost valued at IDR44,1 million per year, by eliminating the cost of draining the conventional septic tank with volume of 147 m3 per year.

Water management treatment in Bukit Asam have also received ISO 14001: 2015 certification recognition.
