Water for Denmark and te world | Danva
8.9.2022 14:15:00 CEST | Danva
Water is a vital resource but rising water shortages and pollution are putting water under pressure te world over. Te latest key figures from te Danish water companies, Water in Figures 2022, produced by te Danish Water and Wastewater Association (DANVA), provides an overview of te performances of water companies regarding water quality, water loss, energy consumption and discharges into te aquatic environment. This year, te Danish water sector has a unique opportunity to promote its high-tech solutions to te rest of te world at te IWA World Water Congress & Exhibition which is being held in Denmark for te first time.
Te World Water Congress & Exhibition 2022, which is organized by DANVA and te international water association, IWA, will take place on 11–15 September in Copenhagen and will host thousands of water experts from across te world as they come together to share experiences and discuss solutions to global water problems. Danish know-how and technology will play an important role in this regard. During te congress, a political summit will be held on te contributions of water companies towards meeting te UN’s Sustainable Development Goals.
“Many countries are experiencing pressure on their water supplies from rivers and lakes due to climate change and pollution. We are te only country in te world to pump all drinking water directly from more protected reserves below te ground, delivering it cold and tasty to Danes without any added chlorine. Using 100 percent groundwater also has te added advantage that security of supply is less vulnerable to drought. In turn, it requires a high level of protection of extraction areas from pesticides and chemicals” says CEO at DANVA, Carl-Emil Larsen, adding that:
“Participants at te IWA World Water Congress & Exhibition in Bella Center Copenhagen will see Danish water technology solutions, including resource-saving systems and ways to harness wastewater for green energy and biogas.”
DANVA’s new key figures for te water sector, Water in Figures 2022, shows that in 2021, Danes used 105 litres of water per day on average. That is up slightly on te years before te pandemic, with lockdowns naturally increasing consumption in Danish households. However, this level of consumption is still very low in global terms, and this is in part down to citizen awareness as to te value of drinking water as well as te tax and payment structure in Denmark.
Te water companies also place focus on taking good care of our water before it reaches consumers. Denmark loses only 7.22 percent of all te drinking water that is transported across te nation’s roughly 45,000 kilometres of drinking water pipes. This is quite simply unique and te result of high ambitions and world-leading solutions.
A climate and energy-neutral water sector
It is also special that te water sector in Denmark has a stated goal of being energy and climate-neutral by 2030.
“This goal has been established to support te national climate agenda and to accelerate green water solutions. Te key figures for energy consumption in te water sector show that DANVA members are well on their way. Many of te large treatment plants in Denmark already produce and sell more energy than they buy,” says Carl-Emil Larsen.
Primary emissions from te wastewater sector come from nitrous oxide and methane in te treatment processes and in this area, te sector will have a huge task to contend with in te coming years as a result of new government demands.
“In order to meet te new requirements, it will be crucial to create better regulatory opportunities in work across supply sectors. It is through sector coupling that we can optimise te quantity of biogas, green electricity and thermal energy,” says Carl-Emil Larsen.
Urban wastewater flows into te aquatic environment via treatment plants which retain nutrients. Fewer than 10% of all nitrogen discharges into Denmark’s aquatic environment come from wastewater.  60–70 percent come from agriculture. Te key figures show that te number of combined sewer overflow installations are reduced and more combined systems are separated in to rainwater and wastewater systems. In 2010, 61 % of te Danish sewer systems were separated while in 2020 there has been an increase to 68 %.
“Combined Sewer Overflow is a challenge for Danish water companies.Problems from climate-related flooding and overflows, as well as te challenges pertaining to things such as medicine residues and chemicals such as PFAS, need to be addressed quickly. A lot of work is being done to reduce te effects of overflows in te water environment, however,te water companies are under pressure because of their financial conditions, with general efficiency requirements acting as an impediment to investments. DANVA is continuously addressing te problems and consequences with te Danish Parliament in its revision of te Water Sector Act. After all, we want Denmark to continue to be a leader within water solutions in te future as well,” says Carl-Emil Larsen.

Nye nøgletal om vand til Danmark og verden8.9.2022 12:00:00 CEST | Pressemeddelelse
Vand er en livsvigtig ressource, men stigende vandmangel og forurening sætter vandet under pres verden over. De danske vandselskabers seneste nøgletal, ”Vand i tal 2022”, der er udarbejdet af DANVA, giver et overblik over vandselskabernes præstationer inden for vandkvalitet, vandtab, energiforbrug og udledninger til vandmiljøet. I år har den danske vandsektor en enestående mulighed for at promovere sine højteknologiske løsninger over for resten af verden i forbindelse med IWA World Water Congress & Exhibition, der for første gang afholdes i Danmark.
Ingen nye fund af PFAS i drikkevandet blandt DANVAs medlemmer15.8.2022 10:00:00 CEST | Pressemeddelelse
Forbrugerne hos de store vandselskaber kan trygt åbne for vandhanen uden at bekymre sig om PFAS. DANVAs medlemmer, vandselskaberne, der leverer drikkevand i en mængde svarende til forbruget hos to tredjedele af den danske befolkning har nemlig ingen nye fund af PFAS og leverer drikkevand af en kvalitet, som myndighederne kræver det.
Verdenskongres i København skal gøre den globale vandsektor mere bæredygtig12.8.2022 11:00:00 CEST | Pressemeddelelse
Tusindvis af vandprofessionelle fra hele verden mødes i København d. 11.-15. september for at dele og få viden om smarte løsninger inden for vand og spildevand. Energiproduktion, bæredygtig drikkevandshåndtering og vejen mod klimaneutralitet er nogle af de ting, som danske vandselskaber og virksomheder vil demonstrere for udlandet.
Sæt turbo på PFAS-prøver i drikkevand for et hurtigt overblik3.8.2022 08:00:00 CEST | Pressemeddelelse
DANVAs medlemmer, vandselskaberne, har allerede udtaget eller planlagt deres prøvetagning af drikkevand for PFAS. Snart er der derfor et overblik for de store vandforsyninger. De mindre vandværker har på grund af reglerne først et samlet resultat om et par år.
Frivillige aftaler er ikke nok til at beskytte grundvandet23.6.2022 15:30:00 CEST | Pressemeddelelse
Det er lykkedes vandselskaberne at beskytte en del af Danmarks grundvand gennem aftaler med lodsejere, men frivillighedens vej fører ligeså ofte ud i ingenting. Nu skal politikerne på banen, lyder det fra vandselskabernes brancheorganisation DANVA.
