PUPR Ministry Builds Centralized Domestic Wastewater Management System in Makassar

Makassar, South Sulawesi, ABIM (27/7/2023) – In his official visit to South Sulawesi, Minister of Public Works and Housing (PUPR) Basuki Hadimuljono with Makassar mayor Muhammad Ramdhan Pomanto, reviewed the Centralized Domestic Wastewater Management System or well known as Metropolitan Sanitation Management Investment Project (MSMIP) program in Makassar, Thursday (7/27).

The MSMIP program in Makassar aims to improve integrated wastewater services in metropolitan areas. The project includes the construction of a WWTP (waste water treatment plant) using MBBR technology as well as the installation of a 6.8-kilometer pipeline network.

“The WWTP was built with a capacity of 16,000 m3/day, or approximately 22,000 connections.” Including household consumers, hospitals, shops, and offices. The primary purpose is to improve environmental quality; as populations grow denser, so does garbage. “As a result, we must process it before it enters the water body,” Minister Basuki explained.

Currently the construction progress of the entire MSMIP Program work package has reached 95%, including the progress of the WWTP development. It is targeted to start operating at the end of 2023.

“The total budget is IDR 948 billion, almost IDR 1 trillion. Currently, the WWTP can operate with a capacity of 1200 m3/day and will continue to increase in line with the completion of the sewerage system. Hopefully in November 2023 it will be connected and can immediately operate, “explained Minister Basuki.

In Indonesia, the MSMIP Program is implemented in 4 metropolitan cities, namely Makassar, Palembang, Jambi and Pekanbaru. Later, domestic liquid waste will be channeled from homes to the WWTP system through a piping installation, no longer using fecal trucks. The waste will be processed until the water quality is safe for the environment. The technology used is the Moving Bed Biofilm Reactor (MBBR) which uses polyethylene biofilms.

MBBR is considered effective in reducing the oxygen content of water decomposing bacteria (Biological Oxygen Demand), nitrification and removing nitrogen. So that the effluent produced can meet the quality standards according to the Minister of Environment Regulation Number. P. 68/MenLHK/Sekjen/Kum.1/8/2016 concerning quality standards for domestic wastewater, including BOD levels below 30 mg/liter.

“This integrated wastewater management system is a new thing that needs to be socialized to the public. The hope is that there will be no more sewage (waste) dumped on the ground and water bodies. Thus, the level of health is increasing and the environment is also getting cleaner,” Makassar Mayor Danny Pomanto said.

Minister Basuki gave the advice to maintain cleanliness and orderliness as well as to add more greenery after observing the progress of the nearly finished work. “When you’re done, don’t forget to tidy it up. If there are remnants of material removed. Please start planting shady trees from now on,” He said.
