There are 67 regulated utilities and total sum of their provided service amount forms 95% of all service amount in Latvia provided by utilities. All utilities are municipalities owned. Water services in Riga (the capital city of Latvia) are provided by a single utility, which has a 59% share of the overall water service market.
The annual volume of services of 13 utilities (including the service provider in Riga) exceeds 500 000 m3. These companies mostly operate in large cities of Latvia and have an 82% share of the overall water service market.

Tariff Setting

Water Management Law states that tariffs have to be determined according to normative acts, abiding principle that all service users cover all costs for water management services justified as a result of economic analysis.
Methodology for the calculation of tariffs for water management services is developed and approved by PUC. It is adopted as a legal act. The water and sewage tariffs are calculated for each water company based on its costs, plus profit margin which cannot exceed 7% of the total expenses (cost-plus regulation). The tariffs are set in euro per cubic meter and they are the same for all types of users. During a tariff evaluation and approval process, PUC verifies and analyses actual and planning costs and documents supporting such costs to ensure that only technologically and economically substantiated costs, which are necessary for efficient provision of the relevant water management service, are included in tariff.

Quality of Service

To encourage high quality of provided services, PUC in sample order organizes annual inspections of service providers. During inspections PUC examine whether merchants provide services in compliance with legal acts and requirements of general authorization.
If PUC detects any unconformity with requirements or legal acts, PUC sets a deadline for corrections. PUC also has powers to enforce execution of its decisions by issuing warnings or setting administrative penalties. Results of inspections are not published.
