New Publication: Guideline for the Appraisement of Sewer Networks
The guideline that will be forthcoming in the German language is an essential assistance for network operators to appraise sewer networks both in detail and consistently. Only by a well-grounded assessment and evaluation of these installations can a proper and regular balancing be ensured. Furthermore, a strong balancing is the prerequisite for a sustained management of the drain and sewer systems in the sense of the existing inter-generation contract that results from the long-life cycle of those systems. Here, sewer operators have the possibility to carry out the necessary collections and evaluations of data either on their part or contract out the services - also in parts - to external service providers.

New Ditch Witch JT100 Directional Drill Gives Power Where Power Is Due
The Ditch Witch® organization announces the release of its most powerful directional drill, the JT100 Mach 1. Equipped with a 268-hp (200 kW) engine, the JT100 is designed so that rotation, thrust, and drilling fluid flow can operate simultaneously at full power, which leads to faster job completion. With 100,000 lb (445 kN) of pullback and 12,000 ft•lb (16 270 N•m) of torque, the JT100 is a directional drill built for both long-range bores, such as river crossings, and installations of large-diameter pipe. The power of the JT100 allows for the addition of two optional features that can save the contractor significant time and money. One is an onboard crane, which is used to load and unload pipe boxes, anchor the unit, and handle downhole tools, especially drill pipe. Directional drills without an onboard crane require additional equipment, such as an excavator, to perform these functions. The other optional feature is an onboard anchor system—an exclusive Ditch Witch equipment option—that stabilizes the machine on virtually any terrain. Directional drills without this feature typically have to be anchored to another heavier piece of equipment, such as a backhoe or track hoe, to maintain stability during drilling operations.

MDPCL successfully complete unique pipe bursting project using the Grundoburst 400S
A recent CCTV survey identified that the cause of repeat sewer blockages at Paget Road, Barry was caused by numerous grade 4 defects in the nearby 300 mm diameter public sewer. To make matters worse, the location of the sewer being so close to properties meant that traditional open cut techniques of pipe replacement was not an option. MDPCL were asked to find the quickest, least disruptive solution to the problem.

First mechanically-excavated tunnel beneath the Bosporus
Completed safely and on schedule with Herrenknecht technology: In mid-April 2009, the Herrenknecht S-391 tunnel boring machine (Ø 6.11m) reached its target shaft in Istanbul. The new "Melen 7" tunnel crosses beneath the Bosporus, which is the sea strait between the Asian and the European parts of the Turkish metropolis. When the interior construction is completed, the tunnel will supply the European part of the city with water from the Asian part. At its deepest point, the tunnel route runs 135 meters below the sea strait’s water level. The construction team and the tunnelling machine excavated this challenging section safely. The first mechanically-excavated tunnel beneath the Bosporus was built in 13.5 months only.
