[...]Easy to open by a single person and made of a robust, durable material: these are features of HUBER manhole covers that have been a matter of course for a long time already. But what are other, equally important requirements on a manhole cover? 1. Meets legal regulations and normative standards HUBER manhole covers always meet currently applicable standards, thus providing safety and the required level of protection for the operating staff. All our covers raised from ground are designed and constructed according to the latest version (April 2018) of DIN 1239 ” Coverings for wells, spring water[...]

[...]The regular inspection of installations is an important aspect not to be underestimated where drinking water and wastewater structures need to be maintained as valuable elements of our supply and disposal networks. Regular inspections are the only way to ensure the plants and their peripherals can safely be operated a long time. It is of fundamental importance to early identify defects, damage and weak points by regular inspection so that these can be expertly eliminated as soon as possible. The risks of continuing with run-down equipment are not to be neglected, especially not in the field of drinking[...]

[...]In Germany, Austria and Switzerland, enough water of high quality is naturally available at any time. One could almost forget that our most important resource is highly sensitive and gives life not only to humans and animals but also to germs and microorganisms. There are therefore good reasons to protect our water resources and use air filters in drinking water reservoirs. “We have never always built water reservoirs without air filters. Why should we use air filters now?” You may have heard this provocative counter-question sometimes from a customer when you recommended that he should improve his[...]

[...]Weltenburg, Germany In 1999, Weltenburg Abbey suffered severe damage from exceptional heavy storm floods. Also in the following years they were repeatedly faced with flood problems. In 2002, when the Abbey was restored step by step, they therefore decided to buy a flood protection system. The Abbey and the Water Management Office Landshut together with the architecture office Magerl and HUBER SE developed special flood protection elements. These elements should prevent the ingress of flood water through the nine basement windows and the 55 windows on the ground floor of the buildings along the[...]

[...]In many respects, water is an indispensable basis of life for humans and nature, because without water there is no life and no economic progress. However, increasing population density as well as developments in the industrial, commercial and agricultural sectors pose ever greater challenges for a secure water supply. Increasingly, seawater and river water are being extracted to meet the growing demand. Water extraction from surface waters: removal of pollutants by mechanical purification gaining in importance Due to the increasing extraction of water from surface waters and the simultaneously[...]

[...]Ruggell, Liechtenstein Due to ever increasing surface sealing high amounts of rain water occur suddenly and flow into the sewer system along with domestic wastewater. As the stormwater amounts which occur are very high therefore, the flow capacity must be regulated by means of stormwater tanks to relieve the sewer system. The municipality Ruggell therefore commissioned the engineering office Wenaweser+Partner Bauingenieure AG in Ruggell (Liechtenstein) to plan the stormwater tank "Kirche". Now as the stormwater tank has been erected the combined water (stormwater and domestic wastewater) [...]

[...]Bayonne, France The water board of the city of Bayonne supplies the drinking water for one third of the population (15,000 persons) from the valleys of Petchonea, Arquetce, Ipharager and Lapeyeren. In 2011, the Bayonne water association decided to refurbish their well shafts for drinking water supply. The refurbishment was necessary as the old bitumen coated manhole covers were leaking. The water board put the refurbishment of about 100 shafts out to tender. The tender specifications were for manhole covers including entrance ladders and installations. The cheapest offer was submitted by the [...]

[...]Magdeburg, Germany The sewage treatment works Magdeburg/Gerwisch was officially commissioned in 1999 after a construction period of two and a half years. It is designed for 426,000 PE and operates with 90 percentage utilisation. An annual average of 17 million cubic metres of wastewater and stormwater is treated on this sewage treatment plant. All coarse waste material is retained in the three-line and two-line screening plant. When the sewage treatment works was planned 15 years ago for the installation of three fine screens, additional space was already planned for the later installation of [...]

[...]Berching, Germany On the basis of the worldwide known and well-proven system of HUBER ROTAMAT® fine screens with wedge wire screen basket we developed the ultra-fine ROTAMAT® Perforated Plate Screen RPPS with perforated plate. The two-dimensional screen (perforated plate) ensures the reliable removal of hairs and fibres and avoids that: fibres and hairs hinder the stable operation of membrane plants and increase maintenance requirements, these materials tend to entangle on the membranes and lead to reduced membrane plant efficiency these products form tresses in the wastewater treatment plant, [...]
