Stormwater pump stations play a crucial role in protecting areas from flooding by efficiently pumping away large volumes of water. This is particularly important for cities and municipalities located near bodies of water, as well as those situated in flat land areas with slow water runoff. When designing a stormwater installation, the primary focus is on reliability. Floodwater often carries solid debris and substantial amounts of fibrous materials such as branches, leaves, weeds, trash, dirt, sand, silt, mud, and soil sediments. The inflow to the pump station can vary significantly between dry seasons and flood events. To ensure secure operation, it is essential to use the most reliable pumps and implement a well-designed station that can effectively handle these challenging conditions. Archimedean screw pumps offer numerous benefits in stormwater applications, combining reliability, efficiency, ease of maintenance, and long-term cost-effectiveness.

The Heemstede and Haarlem-Schalkwijk WWTPs have reached the end of their technical lifespan after 30 years. The wastewater from the Heemstede and Haarlem-Schalkwijk WWTPs will be transported to Zwanenburg WWTP via a new transport system to be constructed. Zwanenburg WWTP is being partly renovated and expanded to be able to process the increase in waste water. This makes Zwanenburg WWTP the largest treatment plant in HHR Rijnland. The renovation and expansion of the WWTP mainly consists of: - a new reception work with 4 perforation grilles and its own odor treatment - an additional aeration tank - an additional settling tank with sludge return auger - an effluent booster pumping station to guarantee the increase in effluent discharge - replacing blower installation with turbo blowers - replacing AT's aeration installations with retrievable aeration - replaced mixers and propellers in selector, anaerobic and ATs - overhaul existing reamers of secondary settling tanks - overhaul existing return sludge augers - conversion of the current reception work into a sludge transport pumping station The initial design capacity of the WWTP will be increased from 6,000 m3/h to 8,400 m3/h due to the expansion work. RWB carries out the mechanical engineering work on behalf of Mobilis within the water purification alliance.

Due to increasing demand, climate change and pollution, it is becoming increasingly challenging to meet all needs in the provision of clean drinking water. This also applies to companies, which means that water reuse is playing an increasingly important role. RWB Water recently realized two Rinsing Water Recovery Units (STUs) for a project with Brabant Water in Tilburg and Loosbroek. These STUs play an important role in purifying rinse water from sand filters, which is usually contaminated with oxidized iron and manganese. Sand filters are essential in purifying drinking water, but they require frequent flushing, resulting in the production of contaminated rinse water. Rinse water can be reused through the use of STUs. STUs clean rinse water by filtration using ceramic membranes. Purification with ceramic membranes has the following advantages, among others: - Minimization of the amount of waste water to be discharged to more than 95% - Low chemical consumption - Low Total Cost of Ownership - Robust and sustainable technology Ultimately, the filtered water can be returned to the drinking water process because of its good quality. In addition to this project, RWB Water has also realized a similar installation for other customers. Examples of these customers are: - Vitens, flushing water reuse installation of 50 m3/h - Grolsch, rinse water reuse installation with a recovery of 95%

By using advanced measured data in TeleControlNet, flow meters in ground can be replaced by calculations. By combining the measured data with the meta data of the pump pits it is possible to calculate the flow rate.

In industrial operations, decisions are made every day based on measurement data. Flow, pressure, level, energy use; These are not abstract figures, but steering signals that directly impact safety, quality, and cost. A deviation of just a few percent in a flowmeter can result in product loss, environmental damage, or even downtime. And with audits becoming more detailed and regulations increasingly strict, inaccurate measurements are no longer just a technical issue, they are a compliance risk. That is why we don’t see calibration as a side activity, but as a strategic tool. If you measure, you need to be sure you’re measuring right. NEW RIGS, NEW PRECISION Since moving into our larger facility in 2024, we have significantly expanded our calibration capacity. Our service workshop in Oud Gastel is equipped with modern rigs capable of calibrating a wider range of instruments, including both ultrasonic and electromagnetic flowmeters. This expansion aligns seamlessly with our ISO 9001:2015 certification, ensuring our processes meet internationally recognized quality standards. ON-SITE OR IN-HOUSE CALIBRATION Depending on your requirements, we offer calibration in our fully equipped workshop or directly on site. In the latter case, our technicians use mobile rigs, meaning instruments don’t have to be dismantled for calibration. We also provide tailored measurement solutions: for companies in need of temporary capacity or additional flexibility, rental or leasing is an efficient option. These services are particularly useful for peak demand, instrument replacement during maintenance, or short-term projects. For long-term applications, we of course also supply new instruments that fit seamlessly with your operational strategy.

On the outskirts of Maastricht, opposite Frontenpark, lies one of the region’s largest pump stations, handling wastewater from approximately 41,000 residents (around 24,000 households) every day. Due to aging valves, several components of the station were renovated in 2025. For Waterschap Limburg, safety and operational continuity were the top priorities during this upgrade. In collaboration with main contractor GW Leidingtechniek and with AVK Netherlands products, an innovative and practical solution was implemented. The old system frequently experienced disruptions caused by wipes and other debris accumulating around the check valves, leading to repeated manual interventions by maintenance staff. “Ensuring the safety of our technicians and the reliable operation of the Veemarkt pump station was our top priority,” explains Gijs Bles of Waterschap Limburg. “The previous check valves caused frequent failures and required extensive manual maintenance. With the installation of new AVK valves, we successfully tackled these challenges, creating a safer and more efficient system.”

What’s Cooking? wanted to drastically reduce its water consumption and enable the reuse of process water within a sustainable and future-proof framework. Their ambition was to evolve towards a closed water loop and become less dependent on groundwater and mains water.

One of our leading products ensures reliable mixing in the flocculation basins of a drinking water treatment plant in the Southeastern USA. Drinking water treatment is one of the most important public tasks worldwide. Even where fresh water is available in sufficient quantities, the water must be clarified, filtered, and disinfected to make it safe for human consumption and for supplying to drinking water systems. There is also no shortage of available water in Georgetown County in the U.S. state of South Carolina, which lies directly on the Atlantic Ocean. A number of rivers together form an estuarine delta here, including expansive marshy areas. The Georgetown County Water and Sewer District Public Water Utility has been operating since 1967. It is responsible for supplying more than 20,000 households and established industrial and commercial enterprises. Among other things, GCWSD operates a drinking water treatment plant, which recently required replacement of aging equipment. These updates included a replacement of their vertical inclined-blade flocculators, which had reached the end of their useful life. In their search for a high-performance replacement that could solve the problems associated with the accumulation of solids in the flocculation basin, while still maintaining good floc formation, the managers found what they were looking for through our local representative, DXP|Premier Water of Charlotte, NC. They ultimately offered the INVENT HYPERCLASSIC® Flocculation System, the world’s leading technical product for this application...

If atmospheric hazards pose a risk in your workplace, how your life-saving gas detection equipment responds to cold, winter conditions should be at the top of your list. Gas detectors are crucial for protecting you from toxic and flammable gases, but cold temperatures can affect their performance. 1. Check Temperature Thresholds Most portable gas detectors operate reliably in temperatures down to -20°C (-4°F). Some even operate in extremely cold conditions down to -40°C (-40°F). Avoid exposing the equipment to temperatures outside its operating range, as this can cause damage or produce inaccurate readings. 2. Ensure Measurement Accuracy Temperature fluctuations can affect measurement accuracy. Regular calibration is essential to ensure reliability. 3. Pay Special Attention to Maintenance - Bump Testing: Perform regular bump tests to ensure the sensor and alarms are functioning correctly. - Oxygen Sensors: Frozen oxygen sensors can fail. Allow them to thaw if necessary before using the detector. - Batteries: Cold can significantly shorten battery life. Charge batteries more frequently and carry spare batteries if possible. 4. Field Use Stabilization: Allow the monitor to acclimate to the ambient temperature for 15-20 minutes before use. Keeping Warm: Hold the detector close to your body to keep it warm. This not only helps the batteries but also prevents internal components from cooling down quickly. Snow and Ice Protection: Cover the detector to prevent snow or ice from getting into the sensors. 5. Plan Ahead and Be Prepared - Backup Equipment: Consider using backup detectors for emergencies. - Training: Ensure your team is trained to handle cold and winter conditions and to follow proper protocols in the event of malfunctions or errors.
