2. Wastewater in Denmark
Basic sewage treatment early 1900’ies and first mechanic sewage treatment plant built in 1948
First Danish Water Action Plan in 1987: regulation of nutrients from agriculture, national criteria for removal of nutrients at WWTP’s (first in Europe), restoration of rivers and lakes
5,5 million inhabitants consume on average 106 liters of water per day at a price of 8,5 € pr m3, Water consumption in Denmark has decreased 15% over the last 10 years, while production has increased.
90% of Danish households are connected to one of the 674 WWTP’s.

3. Organisation, policy and regulation
Ministry of Environment and Food of Denmark: Environmental policy and regulation, WFD implementation
Ministry of Energy, Utilities and Climate: Regulation and policy related to supply of services: water, energy, waste
Ministry of Business and Growth: Economic regulation of water utilities
Separation of authority and operations
Municipalities: Local water and environment authority, responsible for local water plans and compliance with legislation
Water and sewage utilities: organised as private companies, larger owned by municipalities, responsible for water supply, sewage abstraction and treatment, storm water management and partly climate change adaptation

Hvordan er BBR opbygget?
En blanding af nyt og kendt/velafprøvet – der sammen med et solid og effektivt fundament giver en unik løsning.
Tilblivelsen af løsningen var en proces, hvor vi hele tiden havde maksimal effektivitet for øje, forsøgte at indtænke de udviklingsperspektiver, som vi tror fremtiden bringer, men samtidig også skulle opbygge et økonomisk bæredygtigt koncept.
