Drain replacement at Kingsley Lodge for University of Chester

Chester University Kingsley Lodge drain replacement

We at Maxiflow have been proud to work in partnership with the University of Chester on many occasions. The University has gone from strength to strength over the years, and we enjoy helping to maintain our city’s prestigious institutions.

Recently, we completed a series of significant drainage works at one of the University’s accommodation buildings. Kingsley Lodge houses 35 students, just down the road from the University of Chester’s main campus.

Replacing drains at University of Chester's accommodation

Upon investigation it was discovered that the soil beneath the drains had settled, causing the pipes to bow. This meant that the seals between the pipework had ruptured, resulting in leaks and frequent blockages. In addition, there were were a number of infestations of plant roots found throughout the system. Kingsley Lodge’s drains had sustained too much damage to be repaired, and it was determined that a complete replacement was necessary.

Kingsley Lodge’s grounds contain approximately 60 metres of drains, with access provided through 6 manholes. Because the drainage system runs underneath a car park, excavators were brought in to dig down through the tarmac and concrete. Some brickwork manholes were also broken down. We were then able to remove the defective pipework and the excess debris.

We installed all-new preformed plastic drains and manholes throughout the Kingsley Lodge site. Pipe runs and joints were sealed with resin patch liners. High-pressure water jetting was utilized to remove the root infestations from connecting lines. After the pipe works were completed, the trenches were backfilled with layers of sub base. These freshly-filled holes were then covered with layers of tarmac, compacted with a roller and then sealed with hot bitumen.

We would like to thank TP Construction for their assistance on this project, and would also like to thank the University of Chester for furthering their partnership with us.

Drainage works at Chester FC stadium grounds

Chester FC stadium grounds drainage

Previously on the Maxiflow blog, we’ve written about our support for Chester FC and how we’ve taken part in their ‘Backing the Blues’ sponsorship program. We’ve maintained a solid relationship with the club over the years and look forward to working with them whenever we can.

In partnership with Norland Managed Services and TP Construction, we were contracted to solve a drainage problem that was affecting the grounds of Chester FC’s Exacta Stadium (also known as Deva Stadium).

The overgrown hedge envelops the chain-link fence

At the rear of the car park, near the entrance to the away stand, lies a fenced-off drainage ditch. The ditch serves as a runoff point for the surface water that accumulates on the car park’s tarmac, which is then deposited through a culvert into the neighbouring field. The hedge on the opposite side of the ditch had overgrown to the point where the leaves were reaching through the fence, and wrapping around the concrete posts. The dense foliage had completely overwhelmed the drainage ditch, resulting in rain water flooding back into the car park.

The fence was hampering any attempts to deal with the problem, so it had to be temporarily removed. The leaves and branches poking through the chain links were trimmed back, enabling the fencing to be clipped away from the supporting concrete posts. Approximately 160 metres of fencing was neatly cut into lengths, rolled up and stored.

With the fence out of the way, we were able to cut the thick vegetation back to the correct side of the ditch. This confirmed that the ditch was in a bad state, clogged with debris and earth along its length. The next step was to begin excavation, but first the barbed wire running along the top of the fence had to be stripped away. In a similar manner to the fence itself, the barbed wire was snipped from between the concrete posts, carefully coiled up, and stored.

This allowed for the 6-tonne excavator to do its work. The digger was able to methodically excavate the soil and plant life from the ditch. This debris was deposited in an accompanying tractor-led trailer and relocated to a nearby grass verge. With the ditch now emptied, the culvert was cleared using high-pressure water jetting.

Cleared and restored drainage ditch

With the blockages now removed, the fencing and barbed wire were able to be reinstated and the work was completed. This means that visiting teams’ fans will now be able to enter the Chester FC stadium without getting their socks wet. We call that a good result!

Drain excavation and repair at Elton Primary School

Elton Primary School in Cheshire

In partnership with Enterprise, the Maxiflow drainage team were contracted to investigate and repair a reported drain fault at Elton Primary School.

Elton is a village in the North West of Cheshire, and the primary school is attended by approximately 300 pupils. The drain problems were severely disrupting day-to-day operations at the school, and when we investigated it was easy to see why!

Sending cameras along the pipes for a CCTV survey revealed two major issues that were severely impacting the system, in addition to a number of minor structural faults.

Underneath the school’s playground, a section of the drain had collapsed. Because the integrity of the pipe had been severely breached, the contents of the drain were leaking into the surrounding area, potentially contaminating the local water table, and severely affecting the the pressure of the entire system.

Because this problem was too severe for a simple patch repair, our team excavated down to the defective branch connection through the playground’s tarmac. The pipe and fittings were entirely replaced, and were covered in class B bedding before the hole was backfilled and the tarmac was reinstated.

The second major issue lay underneath an access ramp. Two of the lateral connections had become separated due to subsidence, affecting the pressure and flow along a critical intersection.

This presented a minor problem as the access ramp is located underneath a canopy, making access difficult for our large excavator. We accounted for this during the planning stage of the project and allowed for a micro digger to also be present on site specifically for this section of the job.

Once the excavation was completed we replaced the connectors on the laterals, making the connection solid once more. It was also neccessary to reset the pipe level, accounting for the ground shifts due to subsidence.

The minor structural faults identified along the line between two manholes required less invasive repair work. A high-pressure water jetting was carried out inside the pipe, cleaning the line of debris and washing the inner surfaces in preparation for the final stage. Resin patch liners were installed at various points along the line, providing a layer of rigid, waterproof material to reinforce the structural integrity of the pipe.
