Company Angerlehner Hoch- und Tiefbau Gesellschaft mbH has 25 years of experience in the field of construction of tanks and wastewater treatment plants. Scope of works range from common construction works of tanks and wastewater treatment plants to turnkey projects - construction of ready-for-use plants.Difficult geological circumstances as well as construction of tanks and wastewater treatment plants in aquiferous soil ask for special technologies. For example groundwater lowering with well (WWTP Markersdorf and Zeltweg, Austria), vacuum filter (WWTP Laa an der Thaya, Austria) or compaction of soil with vibrofloating compaction in combination with sheet piling (WWTP Wiener Neustadt South, Austria). Furthermore, groundwater lowering in secured excavation pits is executed with several pumps including hoses which transport water into the required sedimentation tanks.

The punctual rehabilitation is a special kind of cured in place pipes (CIPP). The liner seals different damaged spots like rifts, untight sockets and holes and also stops each intrusion of infiltrating water reliably. Additionally, the procedure of punctual rehabilitation is the optimal solution to balance shifted pipes, or to close blind inflows.The glassfibre fleece saturated with resin is installed via installation shaft (manhole) using a Bypasspaker, a rope and TV-monitoring the glassfibre fleece is pulled to the damaged spot. The Parker is blown up with ca. 1,0 bar and pressed against the pipe wall.
