What Sofiyska Voda does

Sofiyska Voda is a regulated water utility company that holds an exclusive concession from Sofia Municipality to provide water supply, sewerage, and wastewater treatment services across the entire capital metropolitan area of Bulgaria, serving approximately 1.3 million residents and a broad base of commercial, industrial, and public-sector customers. The company was established in 2000 as a public-private partnership concessionaire and is controlled by Veolia, the French multinational environmental services group. It sources raw water from mountain sources in the Rila range, including the Beli Iskar and Iskar reservoirs, and operates the Bistritsa and Pancharevo water treatment plants, a citywide supply and sewage network, and a wastewater treatment plant recognized as the only energy self-sufficient wastewater treatment plant in Bulgaria.

Its technology stack centers on conventional treatment infrastructure (chlorination-based disinfection, physical-chemical and microbiological laboratory analysis under an ISO/IEC 17025-accredited Laboratory Testing Complex conducting 150,000+ analyses annually on ~9,000 samples from 87 monitoring points), complemented by digital customer-facing tools: a bilingual website, Android and iOS mobile applications, an online account portal, an interactive water quality map, and a real-time water outage tracker. Multiple payment channels extend across Bulgarian Post, EasyPay, FastPay, several banks, and online wallets. The Laboratory Testing Complex, water meter services, and external laboratory and technical services provide incremental non-regulated revenue streams.

Sofiyska Voda generates revenue primarily through usage-based, KEVR-regulated water supply and sewerage tariffs billed to residential, commercial, and industrial customers within its concession area, with default consumption allocations (6 m³/month for heated, 5 m³/month for unheated properties) applied where metering is unavailable. Secondary revenue comes from accredited laboratory services, technical services (design approval, construction control, network data issuance), and water meter installation and verification. Customer reach is delivered through four physical service centers, a 24-hour phone hotline, mobile and online self-service, and email/SMS outage notifications. The company's roadmap includes the April 2026 transition to electronic invoicing as default, a pricing proposal for the 2027-2031 Business Plan submitted to KEVR in June 2026, and construction of two small hydropower plants approved in July 2025.

Revenue model

1. Water Supply Services: As a regulated water utility under concession agreement with Sofia Municipality, Sofiyska Voda generates revenue through water supply to residential, commercial, and industrial customers within its service area. Revenue is based on water consumption measured by meters, with tariffs regulated by the Energy and Water Regulatory Commission (KEVR). Households are charged per cubic meter of water consumed, with 6 cubic meters monthly for heated properties and 5 cubic meters for unheated properties when meter data is unavailable. Quarterly billing includes adjustment for common consumption differences.
2. Sewerage and Wastewater Services: The company provides sewage collection and wastewater treatment services, with charges integrated into the overall water bill. This includes treatment of wastewater collected through the sewer network and processing at wastewater treatment facilities.
3. Technical and Laboratory Services: The company offers laboratory services and technical services (design approval, construction control, issuance of data for water networks) to external customers beyond mandatory regulated services. These include certified laboratory services, water testing for external parties, and technical consultation services.
