- Collecting more than 15 million liters of rain water to support sustainable agriculture -

-  Reinforcing its ‘Water Neutral’ Commitment in Indonesia -

Coca-Cola reinforces its water conservation commitment in Indonesia by completing two rainwater catchment reservoir projects known as Embung Air (retention basins). Both of these Embungs are located in Central Java, in the districts of Karang Anyar and Wonogiri.

The Wonogiri embung project is dubbed Program Embung Doho because of its construction site, which is located in Doho Village. Besides its water conservation function, this 1.5 hectare-wide embung can accommodate more than 15 million liters of water and also serves as an irrigation source for at least 40 hectares of community plantations or 10 hectares of agricultural land.

Triyono Prijosoesilo, Vice Chief Executive of the Coca-Cola Foundation Indonesia, said: “For Coca-Cola, water conservation is an integral part of our business. In the past decade, various water replenishment programs organized by Coca-Cola in Indonesia has succesfully restored more than 1 billion liters of water back to nature and the community. After constructing more than 4000 infiltration wells in order to maintain water sources in six different areas, last year we began to develop the Embung development program as an alternative to new water conservation programs that can also be expanded to maintain sustainable agricultural and plantation food crops.”

Firdaus Ali as a Special Staff of the Ministry of Public Works and Public Housing, Water Resources Division revealed his apprecation. “We greatly welcome this initiative. This project also supports the priority programs of the Ministry of Public Works and Public Housing in its efforts to achieve water security and food sovereignty in accordance with the Nawa Cita agenda of President Joko Widodo, through the provision of water facilities and infrastructure. The construction of these embungs is also a form of support for climate change mitigation efforts as well as supporting government strategic programs related to improving the economic potential of villages through sustainable farming patterns.”

Embung for empowering the village economy

Embung is a fairly simple infrastructure that utilizes the rainwater harvesting process. Created using a geomembrane layer, the embungs are designed to harvest rainwater by utilizing water containers in an open area and work by adopting the principle of gravity irrigation, without the need for an electric or fuel pump. The depth of this gravity geomembrane embung is usually determined by the rainfall of an area. For areas with an annual rainfall of 3.000 mm/year, the embung is usually made to be 3 meters deep. The Geomembrane material selection itself becomes very important, with essential specifications such as High Density Polyethelene (HDPE), anti UV, anti salinity and Feed Grade for it to be resistant to cracks and able to be inhabited by fish to reduce the risk of larvae proliferation.

The development program of these two embungs costs 2.3 billion rupiah and in its implementation, Coca-Cola Foundation Indonesia collaborated with Yayasan Obor Tani, which acted as its field coordinating partner. The process began by preparing the land, conducting excavation, dumping and compaction by using heavy equipments to form the embankment that surrounds the entire basin. After the embung is physical constructed, it is followed by building the embung ground drainage network and installing the embung irrigation output primary pipes. The work then continued with the installation of the geomembrane sheets to form a complete dimension of the embung by welding it. Completing the process was the construction of sidewalks to lock the geomembrane layers.

The construction of Embung Banyu Kuwung and Embung Wonogiri takes approximately 3 months, using Geomembrane layers and is expected to last up to 30 years. In the embung development program, Coca-Cola and Yayasan Obor Tani have also provided training on embung maintance and water-efficient crop planting training such as planting rice with the SRI system and premium fruits such as Melon, Watermelon, Longan and Durian.

In the global level, The Coca-Cola Company has adopted Water Neutrality as the main focus of its Global Vision 2020, in which the company will restore water back to nature and the community equal to the amount of water used in its products and during the production process. Coca-Cola Indonesia became one of the first countries in the world to go beyond this Water Neutral vision. Since 2015, Indonesia has reached 164% in terms of water replenishment.

Triyono added, “Coca-Cola hopes that the concept of embung can serve as an inspiration and applied by others for the development of embung in Indonesia.”
