Articles & Case Studies

When a large holiday home and caravan park in Cumbria decided to update its 18 sewerage pumping stations, the company turned to Flygt.

Situated just 20 minutes from Lake Windermere, the park boasts over 700 caravans and many additional static holiday homes and offers visitors and owners a variety of sports, walks and breath-taking scenery.

The managing company wanted to update all of the sewerage pumping stations to bring them up to an acceptable performance level with the aim of having zero breakdowns for the coming holiday season. The current pumping stations were suffering from poor performance with the kiosk for the electrics and the control panels showing signs of age. There was also some concern that, without refurbishment, pipework could potentially begin to leak.

The parks management team said: “The Pump stations needed a serious overhaul to bring them up to date and with only limited annual funds dedicated to site refurbishment, it was decided that this year we would spend the money on pump station refurbishment in order to reduce downtime. The key issue was that any refurbishment would need to be completed in a very short period of time, in fact the one month annual shutdown. We had a survey done on the performance of all the pumps and a number of recommendations were made for us to consider.

“I found the engineers from Flygt to be efficient, helpful and relentlessly positive on the several occasions that I met with them – I can’t praise them too highly.”

Flygt, leader in pumping technologies and waste water solutions was happy to offer a free assessment. Neil Siddons, Field Sales Engineer commented: “We were asked to take a look at the condition of the sewerage systems and the effect it could potentially have on their visitors.”

One of the key recommendations was that the level controls should be repositioned or reset, in particular the stop/start and alarm switches on the pumps. “We wanted to move these to the recommended heights and replace any which didn’t meet the required standards,” says Neil. “This would improve both the reliability and performance of the pumps.”

He continues: “One of the major risks identified was in regards to health and safety: Work on the pumps involved having to climb into manholes which could be in excess of 20ft deep and were slippery. We also felt it was important that the replacement pumps were removable to allow future work to be completed safely above ground. To overcome these problems and ensure a safer environment for our service engineers, we utilised our Flygt Easylift.”

Flygt Easylift is an innovative lifting device, designed by Flygt Engineers to comply with Work at Height Regulations when lifting pumps and other equipment from below ground level. The equipment is an ideal solution to the dangers of working over open spaces, manholes, sumps and wells and is acclaimed as a great benefit to employees lifting heavy or cumbersome materials from below the ground.

Neil went on to say; “We positioned the pumps on longer length guide-rails to ensure that, in future, the pumps could be accessed easily and safely.”

Engineers from Xylem completed the work during the annual one month shutdown in January/February; replacing large lengths of pipe work to ensure there would be no further leakage once the park reopened to the public. Neil Siddons explains “We were on a very tight time scale with lots of work to do, but we were able to complete everything on time. It was critical that work on the sewerage systems was finalised before the holiday season began.”

Further analysis of the pumping system found one of the main pumps to be in an extremely poor condition and in need of replacement. The new unit was fitted after the annual shutdown but was replaced without causing any disruption to the running of the park. The pump replacement was a new generation Flygt N-pump which features an anti-clogging impeller, providing the park with the most up to date and efficient technology available.

The result of the hard work and dedication meant that since the completion of the work, there have been no problems or downtime.

As part of the agreement, Flygt Service will maintain all eight of the pumps on site each year to ensure that each season can be just as successful. The park management concluded: “We are really pleased with the work carried out by the team from Flygt. To have a breakdown free season was our ultimate aim and to achieve it so quickly is a fantastic result.”
