With this new equipment Water Supply and Sewerage - Pazardzhik began to replace water mains, regardless of the diameter of the old and the desired diameter of the new pipe. Technology "pipe bursting" is trenchless technology for the rehabilitation and replacement of compromised waterworks. This technology is one of the most promising in the modern infrastructure construction. It is mainly used in large-scale reconstruction and repair of water supply networks. Main advantage of this method is that it does not require excavation of the existing road infrastructure, fences and courtyards of the houses and maintain normal life in the place where there is reconstruction.

Sergey Stoynov: Yes, we do. The first project implemented by using the new technology "pipe bursting" is in the village of Velichkovo. There is performed replacement of strongly amortized section of water main with a total length of 485 meters on the main street in the southeastern corner of the village. For the first two days were replaced 210 old, faulty water mains with new high-density polyethylene pipe. Innovative in this case is that this new method saved 80% of the excavations, about 210 cubic meters fraction at the amount of BGN 4,500, 14 tons of asphalt - BGN 2,000 value and the villagers were with new water main in less than two days.

The social affordability of the price of water is BGN 4,20, currently the price of water is BGN 0,85 VAT excluded. In the town of Pazardzhik and the town in Septemvri we charge channel tax, in other settlements in three municipalities - Pazardzhik, Septemvri, and Lesichovo there is no such fee. The price of water has not been changed since 2010.
