HACH LANGE wins massive instrumentation order

HACH LANGE, the specialist water instrumentation and waste water treatment optimisation company, has received an order from the 4Delivery (4D) consortium for drinking water turbidity monitoring packages.

Drinking water is monitored continuously to ensure that it meets high quality standards and turbidity is one of the most important test parameters. Capable of continuously measuring low level turbidity, the 1720e online turbidimeter meets and exceeds USEPA Method 180.1 for drinking water compliance. Clive Murren, a water industry specialist at HACH LANGE says, "The 1720 instruments are probably the most popular online turbidity meters in the world because they provide extremely accurate, reliable and low maintenance results, even at very low levels of measurement."

Once installed, the new systems, built and designed by HACH LANGE and Linton Electrical, will provide both single and triple validated measurements, further protecting water quality for hundreds of thousands of consumers across Sussex, Kent, Hampshire and the Isle of Wight.

The 4D consortium comprising Veolia Water, Costain and MWH. Combining a wealth of experience and knowledge from within the utility and construction sectors, 4D was established to design and construct both water and wastewater improvement projects for Southern Water.

Commenting on the justification for this contract, 4D’s Chris Hodgson said, "It is Southern Water’s intention to establish the most robust monitoring system possible to further protect drinking water supplies, so the 1720e instruments will ensure that Southern Water customers drinking water is among the best in Europe and fully meets the requirements of the Water Quality Regulations.

"Much of this order represents the replacement of single monitors with triple validation systems. In total, more than 400 instruments will be deployed with up to ten units per treatment plant."
