Project: Semarang Non-Revenue Water Reduction Project
Semarang, a city of 1.7 million inhabitants in North Central Java, Indonesia, faces significant water losses due to physical and commercial inefficiencies in its distribution system. The partnership of WaterWorX and VEI (The Netherlands) with PDAM Semarang, the Non-Revenue Water (NRW) Reduction Project was developed to mitigate these losses. Through strategic infrastructure rehabilitation, active leak detection, and operational optimizations, NRW levels were successfully reduced from 39% to 29%.
Quantifying the Impact
Using the CAP (Credit Aqua Positive) methodology, the project generated approximately 309.2 CAPs annually, equivalent to 302,405 m³ of water savings per year. Over five years, this results in a total of 1,534.5 CAPs. The cost-effectiveness of this initiative is noteworthy, with a calculated investment of €74.1 per CAP.
Social and Environmental Co-Benefits
With these projects we there is not only direct water savings. It also contributes to social-economic and environmental benefits: Job Creation, Improved Water Supply Reliability and Sustainable Water Management.
Looking Ahead
The results of the Semarang project highlight the significance that NRW reduction could play within the broader Water Footprint Compensation strategy. Cities all over the word face huge challenges on NRW. Creating extra financial resources from organizations with a footprint in these cities could support reducing NRW. Now is the time to take action. Join us in supporting innovative water compensation projects, investing in sustainable water management, and making a tangible impact on communities worldwide. Stay engaged, get involved, and help shape a more water-secure future!
About Water Footprint Compensation:
Following the success of phase one, the Water Footprint Compensation program continues to grow, further reinforcing the Act4Water methodology. This approach has now been developed and evaluated across six projects, including the Non-Revenue Water Solutions initiative in Semarang, Indonesia, executed by WaterWorX and VEI.
