Waste/Water Treatment

Project Objectives

The Muirdykes treatment works serves more than 80,000 people in Renfrewshire. Over the last three years, Scottish Water has invested in a range of improvements to treat water discolouration in the area, including £4M of water mains upgrades and the installation of a WEARS ResMix system. This final stage of work involves the installation of a new filtration building and process at the water treatment works, near Howwood. The new secondary stage filtration process will remove oxidised manganese from the system before it goes into the supply zone and will be housed in a single-storey building to be constructed on the site of the Muirdykes WTW. The work, led by Contractors Black & Veatch is scheduled for completion summer 2017.

Scope of Services

Dustacco were engaged by Black & Veatch on a sub-contractual basis, to lead the mechanical installation of pipework and associated equipment for an extension to the existing Muirdykes Treatment Works. The project was challenging due to the high volume of sub-contractors working simultaneously, in a live operating environment with an exceptionally small footprint. In addition, the project required a large scale shut down, and the timescales for completion of the works were considerably short, given the scale and complexity of the job at hand.

Approach & Added Value

Following a review of the initial scope of works, Dustacco’s Project Manager ensured that all mechanical works were delivered to quality standards, on time and within budget. An in-house team of multi-disciplined personnel including design, purchasing, site management and multi-skilled operatives (workshop and site) supported the detailed design, fabrication and installation of stainless steel and mild steel galvanized supports. Large bore ductile Iron pipework was sourced from Scottish Water framework supplier, Electrosteel, and installed by the Dustacco team following the necessary quality checks and approvals.

In July 2016, Dustacco successfully undertook a planned shutdown, to add a main line feed from the primary filters, creating a diversionary feed to the new secondary filters. The planned eight-hour shutdown, with a potential 20 mile impact radius was completed in just four hours, with zero adverse impact on service users.

In addition to the challenges posed by the plant shutdown, a three month delay to the delivery of the ductile iron pipework presented a significant challenge to the project, with a knock on effect for all contractors onsite. However, working collaboratively with the B&V Project Manager and sub-contractors, maintaining continuous communications at weekly project meetings and liaising closely with their own in-house operations manager to flex available resource, allowed Dustacco to re-phase the project, minimising adverse impacts where possible.

Throughout these works, Dustacco’s Project Manager has maintained a presence on site for a minimum of two days per week, providing critical support to the B&V Project Manager throughout.  In addition, the site team of eight personnel was impeccably led by Dustacco’s Site Supervisor, ensuring the highest levels of professionalism, supervision and responsiveness on site.
