Problem

IWS M&E was approached by a key framework client to replace a pumpset that had been identified as a single point of failure. The pumpset was also oversized and running inefficiently. 

Solution

The team was tasked with removing the single point of failure and installing a duty stand-by dual pump. The two identical single-stage, close-coupled in-line centrifugal pumpsets would provide a back-up function in the event of a pump failure, improving resilience and enhancing efficiency savings.

The new Regulation 31 approved pump skid frame was built, assembled and tested in-house at IWS M&E’s Walsall workshop. The equipment was designed to fit the space of the small kiosk where the pumpset was located.

The team removed the kiosk roof which enabled them to use a crane to access the small space from above. They dismantled and lifted out the old pumpset before placing the new dual pump skid arrangement in position. After install a pump alignment check was undertaken, and electrical components were connected. Commissioning of the pumpsets was then completed to ensure it was working correctly.

Challenges

Keeping the water supply running in the area was of critical importance to the client, so only a 48-hour outage was allocated for IWS M&E to complete the pump replacement safely and successfully.

Due to the nature and small size of the site, the team needed to plan the logistics of the work very carefully and consider the health and safety of colleagues and contractors. Traffic management plans were devised, and segregation areas were set up to allow for safe movement around the site.

The small car park was in use by the crane, so the team staggered supply deliveries to enable them to arrive safely. The team also liaised closely with the client during the logistical preparations and any planned client works were deferred to reduce the number of people on site during the pump replacement.

Local electrical subcontractors were used to work more sustainably and reduce the carbon footprint of the work.

Result

An installed and fully operational duty stand-by dual pump was handed over to the client after only 12 hours of outage which surpassed the client’s expectations.

Working closely with the client and contractors to address the logistical and safety challenges meant that the work was completed efficiently, while mitigating the impact of any potential safety risks on site.

IWS M&E received positive feedback from the client site team regarding the design and user experience of the pump skid frame, commending its ease of use and maintenance access.
