Flood protection Surbtal – from planning to implementation
In a first phase, the flood protection concept Surbtal encompasses the construction of two flood retention basins as well as flood protection measures in the industrial area of Lengnau and in the inner city. HOLINGER, as the leading company of the engineering consortium INGE Surb, was responsible for the detailed design for the whole project in 2009/2010. In 2011, after approval of the project, the final design was elaborated and tender published for the...[more]
Flood control Concept for Hindelbank
Due to a lack of drainage capacity in the industrial and commercial area of Hindelbank the village brook leads regularly to large-area floods. Currently, under the lead of HOLINGER, an integrated flood protection concept for the whole catchment area of the river Urtenen is being developed. Within this concept, flood control, ecology, urban drainage as well as recreation and landscape preservation will be looked at holistically. The result of the concept will be an...[more]
New survey of infiltration water for waste water association „erzo“
On behalf of „Entsorgung Region Zofingen“ (erzo), a a new survey of infiltration water in the catchment area of the WWTP will take place. The previous measurements had taken place in the sewer system by night, which falsified the results because of the mixture with waste water from households. They also included leachate and the ingress of groundwater. For that reason, erzo decided to take samples directly at the known point sources. [more]
Renaturation of river Wutach: Planning of the 3rd stage
After the project study and the implementation of the 1st stage, the 2nd stage on the Swiss side of the river Wutach was just finished. The active entrance along the bank involves a raise of the river bed on 800m and the development of a side arm with fens.Currently, the development of the 3rd stage is in planning: it provides an opening and reconnection of a big depression of the terrain, an improvement of flood protection and the dismantling of the last...[more]
HOLINGER Maghreb reaps benefit of 2011 activities
In a difficult market as Morocco is, where, because of the potential of this market, foreign competitors in the field of waste water disposal are strongly represented, HOLINGER positioned itself well with its branch HOLINGER Maghreb. The main actors such as the Moroccan Water Authority (ONEP) and the public utilities of the larger and medium sized cities informed themselves about the references of HOLINGER. Leading Moroccan engineering companies show vivid...[more]
