Ankara Su ve Kanalizasyon İdaresi

What Ankara Su ve Kanalizasyon İdaresi does

Ankara Su ve Kanalizasyon İdaresi (ASKİ) is the statutory municipal water and sewerage administration serving Ankara, Turkey's capital metropolitan area, with 10,000+ employees operating across 25 districts. Founded in 1987 and wholly owned by Ankara Büyükşehir Belediyesi (Ankara Metropolitan Municipality), ASKİ holds the exclusive legal franchise under Law No. 5391 to provide drinking water supply, wastewater collection and treatment, and stormwater drainage services for the metropolitan population. The utility operates the full water value chain: 10 dams with combined 1.45 billion m³ reservoir capacity, the İvedik, Pursaklar, and Çubuk water treatment plants producing approximately 1.66 million m³/day, transmission pipelines including the remote Gerede system and Koyunbaba transfer, district distribution networks, and wastewater treatment facilities.

The organization's technology platform centers on operational monitoring and customer service delivery. SCADA provides real-time supervisory control of treatment plants and pumping stations; ANKABİS (Ankara Bilgi Sistemi) functions as the geographic information system for asset and network management; the Şebeke Bilgi Merkezi (Network Information Center) consolidates infrastructure data; and the Barajlar Bilgi Sistemi tracks dam levels across 10 reservoirs. Customer-facing channels include the 153 24/7 call center, native Android and iOS apps, a web portal (onlineislem.aski.gov.tr), SMS services via short code 2754, WhatsApp, e-Devlet integration, and a network of 80+ SuMatik self-service card-based water vending kiosks deployed across AVM centers, metro stations, and markets.

ASKİ's revenue model combines usage-based tiered water tariffs (4.08 TL/m³ residential, 10.4 TL/m³ commercial, 8.34 TL/m³ government and schools, all VAT-inclusive), wastewater fees at 50% of water consumption rate, one-time connection/participation fees under Law No. 2464, industrial wastewater discharge permits, prepaid SuMatik sales, and occasional property sales. The utility serves a captive customer base segmented across residential (the primary segment), commercial and industrial, government/public institutions, educational institutions, construction developers requiring new connections, and industrial wastewater dischargers. Tariffs are set by the Ankara Metropolitan Municipality Council. Membership in IWA, World Water Council, EBC, NewIBNET, and IFC's Urban Water 4 Cities positions ASKİ within international water utility benchmarking frameworks.

Revenue model

1. Water Supply Tariffs: ASKİ generates primary revenue through tiered water consumption tariffs charged to residential, commercial, industrial, and governmental subscribers. Tariffs follow a tiered pricing structure where unit prices increase with consumption volume. Tariffs are published on the ASKİ website and are VAT-inclusive. Water supply covers the metropolitan area and surrounding districts.
2. Wastewater Collection and Treatment Fees (Atıksu Bedeli): Wastewater fees are charged as a percentage of water consumption (currently 50% of consumed volume rate). This is mandated by ASKİ's Tariffs Regulation Article 34, based on the principle that subscribers who consume water contribute to pollution that must be removed.
3. Connection and Participation Fees (Katılım Bedeli): Water and sewer connection participation fees are charged to new subscribers under Article 87 and 88 of Law No. 2464 (Municipal Revenues Law). These cover expansion, improvement, and new infrastructure investments. These fees have been collected since 1981.
4. Channel Connection Permits and Fees: Fees for sewer connection permits, channel inspection visits, and channel participation charges for buildings connected to the municipal sewage network.
5. Prepaid Card-Based Water Sales (SuMatik): Revenue from prepaid card-based water vending kiosks (Kartlı Sayaç/Sumetik) deployed across Ankara, serving customers who pay in advance for water access.
6. Industrial Wastewater Discharge Permits: Industrial facilities require connection quality control permits for discharging wastewater into the municipal sewer system. Fees are charged for permit applications, inspections, and compliance monitoring.
7. Property Sales (Taşınmaz Satışı): ASKİ generates supplementary revenue through periodic sales of real estate properties (muhtelif taşınmazlar) owned by the utility. These are auctioned through sealed bid processes managed by the Property and Expropriation Department.
