2018

Sweden has 97% of its generated load compliant to the Urban Waste Water Treatment Directive (91/271/EEC).

In 2018, Sweden counted 422 agglomerations generating ≥2,000 p.e. each, of which:

  • 402 agglomerations, generating 12,237,280 p.e. of waste water, complied with the requirements of the Directive; and
  • 20 agglomerations, generating 379,500 p.e. of waste water, did not comply with the requirements of the Directive.

The waste water load generated in Sweden in 2018 was reported to be 12,616,780 p.e.

In 2018, Sweden had not yet reached the target for treating waste water to fully comply with the Directive.

  • All the waste water load is connected to collecting system; and
  • 0.8% of the collected waste water load must still undergo secondary treatment in line with the requirements of the Directive (approximately 100,500 p.e.),
  • 3% of the collected waste water load from agglomerations generating >10,000 p.e. and discharging into sensitive areas must still undergo more stringent treatment in line with the requirements of the Directive (approximately 343,000 p.e.).

0% of waste water load is addressed by means of individual or other appropriate systems (IAS) i.e. non-centralised sanitation systems (approximately 0 p.e.).

For the 422 agglomerations, there are 432 urban waste water treatment plants, with a total design capacity of 13,861,000 p.e., of which:

  • There is no plant active but not connected to collecting system,
  • There is no plant equipped with technology only for primary and secondary treatment,
  • 432 plants equipped with technology for more stringent treatment than secondary.

Based on the 2018 data, it seems that the load generated is lower than the design capacity.

Notice : This table contains only agglomerations with expired deadlines.

*The total [No of agglomerations] includes only those agglomerations that must provide secondary treatment / or more stringent treatment than secondary before discharging waste water from their treatment plants.

**The total [p.e. waste water load] is the sum of the load of all of the agglomerations that must provide secondary treatment or more stringent treatment than secondary before discharging waste water from their treatment plants.

45 agglomerations were not taken into account in calculations of the compliance rate for Article 4 because the agglomerations use IAS for more than 98% of the collected load.

257 agglomerations were not taken into account in the calculation of the compliance rate for Article 5 because these agglomerations generate ≤10,000 p.e. each.

*The target [p.e.] for secondary treatment represents the waste water load (collected and not collected) from all agglomerations that must be subject to secondary treatment, regardless of whether or not the agglomeration complies with Article 3.

** The target for more stringent treatment represents the waste water load (collected and not collected) from all agglomerations generating >10,000 p.e. and discharging into sensitive areas (regardless of whether or not the agglomeration complies with Article 3).

The expected annual investment costs per capita for installing and renewing waste water collecting systems and treatment plants is 47 EUR/inhabitant/year.

The investment needs for ensuring adequate urban waste water collection and treatment, i.e. compliance with the Directive, as estimated by the national authorities and included in their national plan, are at the level of EUR 17.25 million for the period 2020-2023. This covers works on treatment plants, with the forecasted investment cost of EUR 17.25 million (2020-2023) , and works on collecting systems and/or IAS, with a forecasted investment cost of EUR 0 million (2020-2020).However, as indicated in a recent OECD study, Sweden would need to increase their investments further to reach and maintain compliance. The OECD projected that the financing needs by 2030 (total cumulative additional expenditures for sanitation) is EUR 4.8 billion.

For the reference year 2018, Sweden reported the production of 211,604 tonnes of sludge. The sludge is mainly re-used for soil and agriculture (64 %) and others (33 %).Cover of landfill, other use, stored, and not specified use is included in mslReuseOthers

At 1 discharge point, treated waste water is reused for irrigation.

Storm water overflows case was reported on 21 agglomerations for a total of 4,014,126 m3
