The plant is located on two sites on the territory of two municipalities:
- The main platform of the WWTP – 60.014 decares on the land of Lyaskovetz. Of these, 37.629 decares are owned by the Municipality Gorna Oryahovitsa and 22, 385 decares are owned by the Municipality Lyaskovets.
- The platform of the pumping station for waste water – Dolna Oryahovitsa – 2.861 decares owned by the Municipality Gorna Oryahovitsa on the land of Dolna Oryahovitsa.
The domestic and industrial waste water from Gorna Oryahovitsa and Lyaskovets is collected by mixed sewerage and brought to the WWTP by collectors and from Dolna Oryahovitsa by a penstock.
The sewerage was built as a result of the implementation of a project in the water sector over the period July, 2004 – September, 2006 funded by the European Union under the ISPA. It is in regular operation since 21.12.2007.
It is designed to purify sewage waste water from three settlements Gorna Oryahovitsa, Lyaskovets and Dolna Oryahovitsa with 102,000 PE with average flow of 16,028 m ³ per day.
The effluent water is treated under parameters meeting the emission limits under Permit № 13140131 / 06.07.2009 for discharge of a water intake of II grade – the Yantra River – in the "sensitive" area.
