The municipal enterprise KP BMR "Bilotserkivteplomerezha" carried out hydraulic tests across networks fed from 48 boiler houses and nine central heat points while preparing for the 2026–27 heating season. Tests identified 46 damaged pipeline sections; crews had repaired 39 of those by 4 August, with work continuing on the remaining breaks.
Inspectors found problems on the main TEC–city trunk line at several segments, including TK-22 to TK-23 (530 mm diameter), TK-4a to TK-5, TK-7 to TK-8 near the RTI turn, and TK-12; after a refill on 15 June two more damaged stretches (TK-5 to TK-6 and TK-14 to TK-15) were detected and slated for repair. The enterprise also reports completing repairs on 44 boiler houses and 27 heat points and carrying out meter checks, pump replacements, diagnostics, electrical measurements, pipe replacement with pre-insulated sections, and asphalt restoration after emergency fixes. Hydraulic testing uses pressurized water to reveal weak spots so repairs can be completed before the heating season.
