Safety Schemes in Procurement (SSIP) is the mutual recognition scheme for occupational health and safety standards particularly within construction. SSIP facilitates mutual recognition between health and safety pre-qualification schemes saving time, effort and cost of multiple certifications.
Incidences of pollution will have a significant impact on funding throughout AMP7. It’s, therefore, vital that businesses involved in water and wastewater treatment focus on preventing chemical leakages. Hiring or purchasing bunds, structures that underly and wall-off areas containing hazardous chemicals or liquids, thereby providing containment in the event of leaks, represents a small investment. However, it drastically reduces the risks associated with storing chemicals.
Businesses have an array of choices to make when it comes to selecting a bund suitable for their needs. They can opt for a permanent bund, built directly on the treatment site or manufactured off-site, transported and then installed. Temporary or portable bunds, used for smaller volumes, meanwhile, are made from lighter materials. They include intermediate bulk containers (IBC) bunds, which when constructed for movement by forklift trucks are often referred to as pallet bunds.
The most suitable material for the bund must be considered and selected based on several factors, including the size of the storage containers, the nature of the chemical stored, and the bund’s position and environment. The decision is also strongly affected by whether it will be built on-site or manufactured off-site.
The most traditional permanent bunds are built with concrete, brick or block walls, standing on concrete floors. These materials, and any mortar used in the masonry walls, must be watertight and capable of resisting the chemicals.
In recent years, as off-site bund manufacture has grown in popularity, different materials and construction methods have become more common. One alternative for permanent bunds is prefabricated steel. However, this is susceptible to both atmospheric corrosion and attack by the stored chemical, so a special resistant coating must be applied to it.
Together with the growth in off-site and modular manufacture of chemical dosing systems, there has been a considerable evolution in bund construction methodology and design in recent years. For packaged systems up to around 30,000 litres, fabricated polyethylene (PE) or polypropylene (PP) bunds with a rectangular footprint are now commonplace. However, certain design issues must be addressed if they are to be considered viable alternatives to civil-engineered bunds constructed on-site.
When it comes to choosing the capacity of your bund, the UK WIMES: Water Industry Mechanical and Electrical Specifications stipulate that it should be 110% of the total storage capacity of the largest tank or 25% of the total capacity of all tanks, whichever is the greater. However, requirements for outdoor bunds may differ a little between individual water companies. Thames Water, for example, insists on sizing at 110%, while Yorkshire Water extends this to 130% in its own specifications.
Finally, bunds must be protected from the elements and rigorously maintained if they are to function correctly in the long term.
Taking all of this into account, the safest approach is often to buy or hire complete chemical storage and dosing equipment set-ups from WES. They come with the most appropriate bunds, as well as all necessary filling and safety systems, and all components are pre-assembled and pre-tested. For easy installation and integration with the plant’s existing operation, each delivery is also accompanied by the right pipework, connectors and control features.
Hugh Rose joined WES in April 2021 as an Electrical Design Engineer. Hugh works within the Capital Projects department at WES. We asked Hugh a few questions to find out more about him!
Can you tell us about your role?
The role is to aid the senior electrical engineer both within the confines of the factory and on site. This also includes working with the commissioning engineers and technical staff to ensure any details on the drawings are kept up to date. It also involves ensuring that any designs for site distribution both inside and outside the unit are compliant to the latest wiring and water authority regulations, following with the design specification and cable calculations for final documentation.
What has it been like working for WES so far?
Coming from outside the business it has been a bit of an eye opener, the workload is building as I become more acquainted with procedures and compliance issues. The company has a very pleasant working atmosphere with easy interaction between staff and departments.
Tell us about your career path?
My career has been varied to say the least, starting as a Weapons guidance engineering apprentice in the Royal Navy, then training and qualifying as an approved electrician, moving into Film and TV production, running my own business for 20 years and then finally into electrical management and design culminating in a move to WES early this year, managing IEng. accreditation and membership of the IET along the way.
What are your interests outside of work?
Outside work I collect and restore analogue sound equipment and have a small music studio at home left over from my TV days. I also enjoy travelling and spending time with my grandchildren.
Lawrence Wretham has recently joined WES as a Proposals Engineer. Lawrence will be assisting Les Bunce in the Hire division. We asked Lawrence a few questions to find out more about him!
Can you talk to us about your role?
My role is to assist customers with their requirements for hired dosing systems. I will visit site, measure up and try to find the best solution for their dosing needs. I will send a comprehensive, itemised proposal and will recommend a full solution built around the customer’s choice of chemical.
What has it been like working for WES so far?
Genuinely interesting. I’m really impressed that we have such a wealth of knowledge here and so many time-served experienced people. Our ability to manufacture is also remarkable as it combines several disciplines and processes so well. I’m constantly learning.
Tell us about your career path?
I come from a construction industry background and have been in equipment hire for a long time. I was a branch manager for a major equipment hire company for several years. When I was at school, my first Saturday job was with compressors and air tools. I did a brief stint as an estate agent in the early 1990’s, but I’m OK now.
What do you like to do in your spare time?
I have quite a few hobbies! I am a keen cyclist and am always restoring at least one old bike.
I ride a unicycle (I used to commute on it) I am learning to weld. I fix old computers and laptops. I love to visit historic places and have been to almost all the English Heritage castles in Southern England. I listen to lots of music from classical to rock, metal, rap and world music and love live music events.
Sam Anderson, an engineering undergraduate, will be working with WES over the next 13 months as a part of a placement year for his university course. Placement years are a great option for students to develop skills and gain valuable experience before graduating and entering the working world.
What course are you studying?
M.Eng Chemical Engineering at The University of Birmingham
How have you been finding the first few weeks at WES?
The first few weeks have been excellent, it’s been great getting hands on with setting up and commissioning pumping systems; and seeing the design process I have studied being used in industry. It’s been a steep learning curve – but I can’t wait to continue integrating with WES and ultimately be managing projects of my own!
Why did you choose to do a placement year?
I always wanted to include a year in industry as part of my degree, the exposure to the working world in advance of obtaining my degree will be invaluable in applying for grad jobs. Also, I am looking forward to developing skills that can’t be obtained in lecture theatres and tutorials; building working relationships with qualified engineers and managers and absorbing the advice they have to offer.
From two weeks working with WES, I am already seeing the benefits of working for a small, rapidly growing engineering firm. The closeness of the business allows me to gain experience in multiple departments, from commissioning and building dosing rigs in the workshop and on site, to managing projects and designing systems in the CAPEX business office.
How will the placement year impact your final year of university?
By spending a year with WES, connecting the dots between engineering concepts and engineering practice, I expect I will be able to understand final year content quicker and with more depth. For example, I am already better at visualising a built system from a paper P&ID, something which took longer during my third-year design project.
WES Ltd are excited to announce the purchase of an additional new facility. Directly next door to the existing WES facility, the 2 units combined will nearly triple our existing capacity providing 28,000 Sq/Ft of workshop & office facility within a 2 acre site.

Love it or ditch it?
Let’s face facts, when equipment breaks down, the primary concern is how will productivity and profitability be impacted in both the short and long term? Not to mention the general public’s water supply being disrupted if there is downtime at the water and wastewater works.
When breakdowns occur, we go back to the age-old question of repair or replace? It is a decision that requires careful consideration in order to maintain productivity and manage costs. Corporations have long used the 50 per cent rule as a guide: if breakdowns and repairs exceed 50 per cent of the total cost of replacing equipment, then you should replace it outright.
However, in a world where repair and remanufacture promotes a circular economy and is the more sustainable option, the regular servicing and maintaining of equipment mean that those old 50 / 50 guidelines are shifting.
Systems must be maintained regularly
Reliable and efficient chemical dosing systems, for example, are vital to the regulatory compliance, safe management and cost-effectiveness of water and wastewater treatment operations. To avoid equipment failures and minimise leaks, spills and blockages, these systems must be properly and regularly maintained. However, as we’ve seen over recent years, many companies are falling short of this.
In fact, when the Environment Agency released its latest annual report on the environmental performance of England’s water and sewerage companies, it showed that four out of nine companies are falling short of expected standards, which is having a detrimental impact on the environment. Ultimately, if you are not maintaining your equipment regularly you will have no choice but to replace it and perhaps face other consequences. Not making maintenance your priority has other repercussions too:
Shortened asset life
Poorly maintained dosing equipment simply won’t last as long and a replacement will mean adding to the company’s capital expenditure (CAPEX). Most other savings achieved through maintenance relate to operating expenditure (OPEX). Considered holistically, the benefits of good servicing can be combined to enable effective planning and optimisation of total expenditure (TOTEX).
Without regular servicing and recalibration where necessary, a dosing system can end up injecting larger quantities of chemical than needed. Energy consumption may also increase when equipment isn’t functioning at full efficacy.
If the doses from a failing system are too low, insufficiently treated wastewater may be discharged into the environment. If doses are too high, the discharge may be toxic. In the event of a significant chemical leakage or untreated discharge due to faulty equipment, the effects on rivers, streams and other habitats may be devastating. Along with the cost of fines, enforcement undertakings and remedial works, the company will be facing a PR disaster.
Breakdown? Have you considered hiring a chemical dosing system?
Other maintenance-related services from WES include replacing components, upgrading or re-purposing systems, relocating equipment, modifying controls and training operators.
As an alternative to replacement, we can also support operations through various other solutions. This includes the rapid delivery of hired dosing systems in emergency situations, or where planned shutdowns are scheduled.
In short, whatever a business needs to keep its chemical dosing systems well maintained, we have alternatives so that the fallback doesn’t have to be replace.
How can WES help?
Specific maintenance needs vary between sites, applications and the nature of existing equipment. We offer a free on-site survey to audit the chemical dosing system regardless of age or manufacturer, against current standards and best practice. An assessment of the equipment’s general condition is produced, along with recommendations on any repair or upgrade work needed. Based on those reports, WES will make a recommendation.
