Repairing sewers without excavation
When repairing sewers, the UK based company OnSite’s nodig solutions can often use manholes rather than digging up roads: Until about thirty years ago, once a sewer was built, there was no way of inspecting the inside. But with the emergence of closed-circuit television, the poor condition of many sewers was revealed. Pipes were often cracked and groundwater infiltration was increasing the volume of sewage at the pumping stations. This led to an overload of the system, with sewage overflowing into watercourses. Treatment plants were working unnecessarily to process the additional volume and sometimes sewage seeped directly into the environment through the cracks.

100 Years Modern Water Supply in Stara Zagora, BG
On October 3rd 2008 the town Stara Zagora celebrated 100 years of modern water supply. The first networks, however, were built long before 1908: Stara Zagora with its 120,000 inhabitants is situated in central Bulgaria and is known for its ancient Roman water supply system. During the town’s recovery and rise from the ashes of arson and pillage during the Russian-Turkish liberation war in 1877-1878, ancient relics dating back to the 6th century B.C. were found and preserved for the public. Archaeological findings amongst these were clay pipelines and aqueducts which were built during the Roman times and which already then carried water over great distances for the town’s supply.

egeplast high-pressure pipe passes a high-pressure test of 50 bar on the test bed
The new egeplast HexelOne pipe makes possible both high-pressure applications as well as a reduced usage of material in familiar applications. The reason: As compared to the existing polyethylene pipes, it has about double the strength. The new plastic pipe is made from polyethylene only in a new manufacturing process - the HexelOne process. In this method, even residual pieces can be recycled, making it environment-friendly. This is an important advantage, especially in times of continuously increasing raw material costs.
