Multiobjective design of sewer networks

The sewer layout in flat areas significantly influences the construction and operational costs as well as reliability of the network performance. To find an optimum design of sewer networks for flat areas, this study presents a multi-objective optimization problem with the objective functions of 1- the cost and 2- the reliability. The reliability criterion is defined as the effect of a clogging...

Remnants of sewer gas.

Going home after a housing co-op meeting, a friend offered to walk me to the bus stop. ‘‘I’m going to show you something’’ he said ‘‘and you won’t believe you’ve passed it so many times and never seen it before’’. As we rounded a corner he halted and I saw what I thought to be the base of a lamppost. Then I looked up, having to tilt my head back to see that this ‘lamp post’ was headless and at ...

17 Sewer Robotics

The usage of tethered, remotely controlled robot platforms in sewer pipes has become widely accepted. Research and development in engineering have moved the original application field of merely visual inspection to manipulative tasks such as the actual repair of pipe sections, installation of cable, e.g. for communication. Despite all engineering advances in the mechanical design of the platfor...
