Sykes Pumps provides customised solution for Hinkley Point C water management requirements

Pump specialist, Sykes Pumps, is to install the latest pair of custom-modified pumps sold to EDF Energy’s Hinkley Point C site in Somerset as part of the water management strategy implemented by Tier 1 contractor, Kier BAM Joint Venture.

The 430-acre site, which will be the first in a new generation of UK nuclear power stations, has been divided into six Water Management Zones (WMZ) during the construction phase to manage groundwater and rainfall as the build programme progresses, while ensuring that all water returned to natural water courses from site is cleaned to the highest environmental standards.

Sykes Pumps has been involved with the Hinkley Point C site for the past four years and has already hired a range of submersible, diesel and electric pumps for various elements of the development programme, including the sale of twelve custom-built electric surface-mounted pumps for WMZ|’s 1-6. The latest installation in the WMZ roll-out is for WMZ 4, which will involve the installation of two 22kW pumps to work in conjunction with a silt separation process.

The pump units have been custom-built to include Sykes Pumps’ automatic self-priming capabilities to enable instant start-up and priming on demand, along with sophisticated control systems that will ensure the required level of flow is pumped through the system, based on monitoring of groundwater conditions and rainfall. One of the specially-modified pumps at WMZ 4 will be used to pump water from the groundwater storage lagoons, where water from each WMZ is diverted from the deep dig excavations. It will then be pumped through a silt separation unit into a second lagoon for cleaned water. The other pump will take water from the cleaned water lagoon following water quality monitoring, and pump it back into the local water courses. Each WMZ pump system has been designed to adjust the flow rate aligned to groundwater and weather conditions so that the capacity in all lagoons can be maintained at optimum levels at all times.

Explains Bob Lima from Sykes Pumps, who has been responsible for commissioning the pumps: “Kier BAM provided us with a maximum flow rate for each WMZ, based on worst-case scenario storm levels. The controls fitted mean that the pumps are only in use as much as they need to be to help manage the water on site while offering sufficient resilience to ensure flooring is avoided during any periods of severe weather.”

The maximum flow rate for WMZ 4 is 160 litres per second, which is less than that for WMZ 3 where the 320 litres per second maximum flow rate requirement resulted in the specification of two larger 55kW pumps. All pumps have been built with variable speed motors to ensure pump speeds can be tailored to suit real-time site conditions.

Sykes Pumps has provided training for the Tier 1 team on site and also has a four-strong team of engineers permanently based at Hinkley Point C to carry out the planned servicing of the hire pumps every two weeks in addition to any reactive maintenance requirements.

Peter Pearson, from Kier BAM, comments: “The pumps provided for the WMZs are just one of the solutions that Sykes Pumps has delivered for the complex requirements of this large, coastal site.

“Sykes Pumps was able to design a flexible solution around the specific demands of our water management strategy, delivering an installation that addresses both the need to control groundwater and the imperative for limiting unnecessary energy consumption whilst ensuring we uphold the highest environmental standards.”

Andrews provides heating for major agricultural show in Scotland

Andrews Heat for Hire was recently involved with a major agricultural event that takes place annually in the county of Aberdeenshire, Scotland.

The well-known show takes place over a six-week period and includes animals competitions, trade stands, music, arts, children’s activities and other popular attractions.

Given that the festival was scheduled to take place during the height of winter, the organisers were extremely keen to source a temporary heating solution to ensure visitors were kept warm throughout.

After originally being contacted over the phone, an Andrews specialist was sent to site to assess the situation, speak to the customer and come up with a heater hire package that was befitting of the application. After carrying out a site survey, our engineers installed six ID65 Indirect fired oil heaters outside the client’s main marquee and used ducting to ensure large volumes of warm air would raise temperatures inside.

These units were specifically selected because of their aptitude for delivering a safe and clean supply of hot air to environments where constant operation is required.

We received the enquiry during the Christmas period, and our team was able to react extremely quickly to provide a perfect solution despite the short notice. Fuel buggies and tanks were also provided to ensure the heaters could run unattended for extensive periods, as was necessary.

Our equipment is scheduled to remain with the customer until the event’s conclusion and our regional engineer has since revisited site following installation to make sure everything is still functioning as planned. We’re pleased to report that our solution has successfully combated the bitter Scottish weather and allowed guests and visitors to enjoy their experience.

Sykes Pumps helps secure continuity during water shortages

A flexible pumping solution was key to ensuring water continued to flow in Essex and Suffolk during last summer’s heatwave

Last summer’s prolonged heatwave put water companies under immense pressure to maintain supplies, with increased consumption exacerbating the challenges of reduced capacity on the network. The problems were particularly acute in East Anglia, where the temperatures reached record highs for record periods and farmers were forced to water their crops to protect yields.

To address these severe conditions, Essex and Suffolk adopted a strategy of supplementing the existing infrastructure by recommissioning disused assets in order to put more water into the supply chain. For the rural Norfolk villages north of Norwich, this meant re-activating a disused pumping station in the village of Horning and Sykes Pumps was brought in to provide a temporary pumping solution that would enable the use of an asset that had been out of service for 40 years.

Flexible solution

The nearby pumping station at Belaugh provides the local area with 27 mega litres of water per day to Ormesby WTW, supported by abstraction from the Trinity Broads to meet the needs of local households, businesses and farms. However, reduced rainfall and operational constraints meant that this capacity was compromised and Essex & Suffolk Water secured permission from the Environment Agency to resume abstraction from the area’s main natural water source, the River Bure at Horning. To do this, the water company needed to re-activate the disused pumping station at Horning but, after 40 years of inactivity, the existing pumps could not be used due to their age and state of repair.

To work around this, Essex & Suffolk Water’s contractor, Integrated Water Services, contacted Sykes Pumps to discuss a pumping solution that could abstract the 2-3 mega litres of water they estimated would be required to supplement the supply from Belaugh. The solution would need to use the existing pumping station to put the additional volume into the treatment works while overcoming the need to reactivate the existing pumps.

“One of the challenges of the brief,” explains Mark Burden from Integrated Water Services, “is that we didn’t know how hot it was going to get or how long it would be until the dry period ended. Not only did this make the amount of water coming into the system unpredictable but it also made it hard to assess how much strain additional consumption would put on the network. Our aim was to generate an additional two to three mega litres of water per day but there had to be some flexibility in the solution because we didn’t want to take more than we required but we had to be able to ensure continuity of supply.”

To ensure that the temporary pumping installation met Essex and Suffolk Water’s requirements, the Sykes Pumps team visited the site to carry out a full specification could be drawn up.

Tailored installation

Explains Sykes Pumps hire manager, Rob Richards: “The customer wanted a robust solution that would allow them to increase capacity quickly if the situation escalated. Our response was to provide two duty pumps and a standby, along with two accessories needed to connect the temporary pumps with the existing infrastructure, adapting the fittings where required to align to the temporary pumps to existing connections.

Sykes Pumps supplied a silenced UVO 150/100E pump as the main duty pump, which typically provides a maximum head of 93 metres and a flow fo 120 litres per second. Mark Burden continues: “We were planning for a worst-case scenario situation but the combination of pumps and the design of the solution mean that we were able to use it in a best case scenario way, reducing the abstraction required from the river. Originally, one of the UVO 200/150F (D90) pumps was specified as a duty pump but we were able to keep this on standby and only use the smaller pump.”

While the duty pump was a 6″ unit, Sykes Pumps adapted the set-up to use 8″ hoses so that everything on site was standardised. The pumps were connected using 200mm wire armoured Bauer suction hoses to abstract the water and 200mm high pressure flanged discharge hoses to feed the abstracted supply to the network.

Rob Richards explains: “Three suction hoses per pump were designed to pump the water out of the pumping station chamber supplied by the river and a 23m flanged high pressure hose connected the pumps to the nearest point on the raw water main to Ormesby WTW.

Ample contingency

“The existing pipework connections were 450mm so we also supplied a number of gate valves, non-return valves, adapters, reducers, bends and Y-pieces to enable secure and leak-free connection to the 200mm hoses. We were able to use our experience of a similar project at another location, along with the initial site survey to designed to the solution to fit the requirements on site.”

The temporary pumping solution was installed by Integrated Water Services with the support and advice of the Sykes Pumps team who assisted with connecting the pumps up. While all three pumps remained on site into September wehen the heatwave had passed, only the UVO 150/100E 6″ diesel pump was actually required to boost the water supply throughout the summer months.

Mark Burdens adds: “The water shortage was not as severe as we thought it might becoming but having plenty of contingency was the right choice. With Sykes Pumps’ help we were able to bring an asset that had been out of use for four decades back into service and our experience this summer means we know that we can utilise this solution to provide additional capacity in the future.”

Hired drying arrangement assists school renovation development

Andrews Heat for Hire was recently approached by a construction company after it took over the renovation of an academy school in West Sussex. With work in the latter stages, a hired drying solution was required.

Cold November temperatures in the region meant that it would take far longer than the time available for plaster and flooring to dry inside the new building. The contractor responsible for the project contacted Andrews Heat for Hire before one of our local experts visited the premises.

After carrying out a free site survey of the building and discussing the best solution with the customer, our engineer proposed the installation of an Aurora FH2000 alongside four ASF50 fans. The heating unit was capable of supplying up to 200kW of warm, dry air with the fans deployed simultaneously to maximise air movement.

The FH2000 was situated inside the school’s forecourt with lengths of ducting used to help distribute hot air inside separate entrances. Once operational, the hired drying arrangement worked quickly and effectively to dry cement and wall surfaces.

As a result, our client was extremely complimentary of the set-up and knowledge of our technician before confirming they would be contacting us for similar projects in the near future.

Business as usual for Andrews Sykes this Christmas

Those hoping for a white Christmas this year will once again be disappointed with forecasters suggesting that December 25 will be a dreary wet day for most of the UK!

The news has been coupled with the Met Office issuing a series of flood warnings across the country with the South West likely to be the worst-hit area. We’re now in the darkest week of the calendar year with heavy rain and cold weather expected to strike nationwide.

Meteorologists have even gone as far as suggesting that imminent downpours and gales present a ‘threat to life’ and that businesses in the affected regions are at risk.

More than twenty flood warnings are currently in place less than a week before Christmas and there are fears that heavy rainfall could have serious of implications for millions of people in England and Wales.

This is not the first time that devastating weather has threatened to cause havoc over the festive period after the infamous flooding of 2015 left much of the North in a state of chaos.

How can companies protect themselves against winter conditions?

As winter approaches, there are many reasons why you may need to consider a temporary heating hire solution. With temperatures starting to plummet across many parts of the UK, we must contemplate how this can affect your company’s staff and operations.

According to UK government guidelines, it is the responsibility of your employer to maintain a ‘reasonable’ temperature in your place of work – and this varies from industry to industry. In 2017, a survey conducted by Andrews Sykes revealed that productivity within an office environment is heavily impacted if temperatures are either too hot or too cold. Up to 80% of those asked admitted to complaining about the temperature of their office, which underlines just how widespread the problem is. These statistics also demonstrate the importance of maintaining the correct conditions which renders a source of heating essential during the winter months.

What should I do following a heating failure?

So, what happens when your heating system is no longer up to the task or breaks down completely? An absence of suitable climate control could jeopardise output and the efficiency with which your staff work, which is a completely undesirable scenario for any business. A solution should therefore be sought as quickly as possible – and it’s easier than you think.

Christmas Dinner brought to you by Andrews Sykes!

With the 25th December now nearly upon us, households nationwide are preparing themselves for Christmas festivities which will in many cases include having lots to eat and drink! Supermarkets this week will be packed with last-minute shoppers desperate to snap up seasonal bargains, but for us at Andrews Sykes, there has been a slightly different type of pressure to contend with.

In the weeks preceding Christmas Day, we have been extremely busy helping to ensure that British retailers receive sufficient quantities of the ingredients needed for a traditional Christmas dinner. As you might expect, the demand for turkeys and vegetables swells around this time of year which in turn leads to a sharp upsurge in the need for appropriate storage space.

This increased seasonal requirement has seen Andrews Sykes undertake a number of significant projects as a direct result. A large farm in the Worcester area sought a number of our indirect heaters in order to keep thousands of turkeys healthy ahead of their distribution to wholesalers. Similarly, our dehumidifiers have been on hire across the country to enhance potato shelf-life while a combination of drying equipment and heating units have also kept Brussels sprouts in perfect condition once harvested.

Safeguarding the supply of perishable food keeps cost prices affordable and ensures demand can be accommodated even during peak periods. You could say that our tireless work and 24-hour service has played its part in providing Christmas dinners to millions of people across the UK!

Thermostat arguments hotting up with winter now upon us!

With Christmas fast approaching and temperatures plummeting accordingly, couples up and down the country are engaging in intense stand-offs – and you might be surprised about the reason why.

An annual battle for the thermostat seems to have commenced in most households which has predictably sparked an endless cycle of disagreements.

Andrews Heat for Hire recently surveyed 2,000 cohabiting couples on the matter, with around half of respondents admitting that they have quarreled with their partner over the temperature of their home.

Our findings also uncovered that more than 90% of people switch their central heating back on before December which means that arguments are extremely prevalent at this time of year!

A common cause of conflict is the cost of overuse, with 62% of those asked pinpointing rising energy bills as a factor they’re particularly wary of. This mindset is responsible for one in seven couples delaying warming up their property for as long as possible.

Naturally, some take matters into their own hands. Almost 60% have returned homed to discover the temperature has been changed to befit the preference of their partner – a regular catalyst for spats!
