Our technology optimization outreach program has for 2016 secured 16 opportunities for disseminating 
our industry contributions, by being part of major technical programs in events such as WEFTEC, IWA’s 
Leading Edge Technology Conference, Singapore International Water Week, and IWA’s World Water 
Congress. 

Performance Measures & Results 

Your Performance Measure(s) 

Your Results (quantitative or qualitative) 

Level of employee engagement in the goals 
and vision of the Utility of the Future 
business model
 
 

Through our ongoing internal surveying efforts, we have 
documented that 89% of our employees understand, feel proud 
and support our strategic goals and related activities in being a 
local and global relevant organization. 

Support of Staff development through 
focused training programs 

VCS has a broad range of different training activities internally in 
our company. Almost 95% of our staff was actively involved in 
training and competence enhancement last year and the average 
time per employee spend on training was exceeding 50 hours 

Level of global engagement by our staff 

We participated in technology knowledge sharing and institutional 
capacity building activities in the following countries: USA, Russia, 
Bangladesh, Vietnam, Indonesia, Malaysia, Singapore and South 
Africa. 

 

  

ENERGY GENERATION & RECOVERY 

 

Indication of management commitment (e.g., standard operating procedures; board/executive 
management renewable energy conversion policy, including quantitative goals developed and 
shared with stakeholders)   

 

Internal energy sources evaluated (e.g., biogas, hydropower, heat in wastewater), and/or 
renewable energy sources evaluated on an ongoing basis (e.g., solar, wind, co-digestion)  

 

Recovery of digester gas in a combined heat and power (CHP) system, and boilers in place (for 
process and building heating)   

 

Conversion of digester biogas to electricity and heat, and/or transportation fuel Yes   

 

Solar panels, wind turbines, heat recovery, in conduit hydro, and/or hydroelectric power 
generation systems installed  

In 2010, VCS adopted the goal of becoming CO2 neutral by 2014 and by 2013, the Ejby Mølle WWTP (at 
385,000 population equivalent capacity, the VCS largest facility) was already energy self-sufficient able 
to meet its very stringent nutrient removal goals. This was accomplished by reducing energy 
consumption (primarily from the biological nutrient removal processes by optimizing simultaneous 
nitrification/denitrification) and by redirecting carbon from primary treatment to the anaerobic 
digestion/combined heat power system for both electrical and heat energy generation and recovery.  

Since 2015, the plant has become a net energy producer (150% of energy requirements), both in terms 
of electrical power generation and excess heat recovery which is being used in a district heating system 
serving the community around the treatment plant. The main contributions to this significant conversion 
was the adoption of a sidestream deammonification system that was configured with mainstream 
deammonification conversion capabilities. This capability, which is currently in start-up mode, will 
further efforts of decreasing energy consumption and increasing energy generation at the plant.
