Elnusa has an integrated solution to provide the need for quality and quantity of clean water to cater to the sustainability of the community and the industrial sector. The construction of a Clean Water Treatment Plant (IPA) begins with a preliminary survey of field conditions; from the quality of raw water, water discharge, to the condition of the area that is designed as the Plant - by planning based on the conditions and needs of the location. The construction of this IPA adopts Dissolved Air Flotation (DAF) technology to the efficiency of space. There is no need for a large area of land for the operations, and it can save the use of chemicals, the speed of water-splitting, and the time of the maintenance; hence, minimizing Non- Productive Time (NPT) ). The treatment process produces safe, clean and quality water, which can be recycled to support the daily needs and activities.

With the support of Smart Water Meter (SWM) technology, being one of Elnusa's flagship products, water usage can be measured and monitored online and in real-time. This way, the production and water treatment processes can be carried out efficiently. Elnusa won the tender at the end of 2019 for the WTP development cooperation project. The Company has also played a role in several Water Treatment Plant (WTP) projects, including as a Joint Construction Partnership Partner in investment, construction, processing and management projects for WTP with a capacity of 900 m3/hour. The Phase 2

WTP construction has earned the trust from PT Perkebunan Nusantara III (Persero) to support its business activities in the Special Economic Zone (KEK) area in Sei Mangkei, North Sumatra.
