Project The municipality of Arnhem has selected Combinatie Moerriool (Van der Ven en Kumpen NV) for the renovation of the sewer under the Sonsbeeksingel (phase 3). This historic sewer, built in the early 20th century, drains waste and rainwater from Arnhem-Noord and -Oost. Renovation method Due to the depth, nearby trees and traffic congestion, the sewer is being renovated from the inside to limit inconvenience. This is done with life-extending measures such as polymer concrete slabs and crack repair. Civil engineering work, such as paving and manhole covers, are also part of the project. Planning & collaboration The construction team phase runs until early 2025, after which the implementation starts and the project will be completed in early 2026. Combinatie Moerriool is building on previous successful renovations of the sewer. Client: Municipality of Arnhem Implementation period: 2025 - 2026 Contract form: Construction team

Van der Ven is working with Waterschap Hollandse Delta on the renovation of the Spijkenisse Sewage Treatment Plant (RWZI). The aim is to make the plant technically suitable for the next 15 years. The work includes: Construction of a new reception area with installation for removing grid waste. Realisation of an anaerobic tank. Replacement of the sludge dewatering line with a thickening plant. Construction of a new sludge buffer and demolition of the existing sludge silo. Installation of new electrical systems and field cabling. Renovation and replacement of mechanical components and utilities. These renovations ensure that RWZI Spijkenisse complies with legislation and regulations, sustainability requirements and a lifespan of at least 15 years.

Need extra capacity quickly, a temporary assignment, or don't want a large upfront investment? With our rental services, you choose flexibility and security. We have a fleet of over 1,000 liquid-tight containers ranging from 7m³ to a generous 80m³. This allows us to offer a robust solution for storage, transhipment, and (waste) collection, even when leak-free operation and safety are paramount. Our containers are used for (contaminated) sludge, process and wastewater, manure, oil-containing substances, remediation projects, and emergency response. This way, you quickly have a practical and safe solution on site, precisely tailored to the work. Why rent from Schenk Container Rental? • Delivery within 24 hours (where possible) • Domestic and international delivery • Our own transport service: fast response and short lines • Every container is visually inspected and tested for liquid tightness before delivery. This ensures you receive a container that meets the requirements and is immediately ready for use. Looking to rent a Collection Press Container (IPC)? Besides containers, you can also rent an Incoupler Container (IPC) from us. This is a removable compactor mounted on a vehicle to process and compact waste from above-ground and/or underground containers. Ideal if you want to collect more efficiently and minimize transport movements. Free advice and fast availability. Want to know what's best for your situation? Schedule a free consultation or call. Briefly tell us what you want to store or collect, the volume, and the expected delivery time. We'll then recommend the right container or compactor and check availability immediately.

The Upgrade (U-Series) from E/One is a replacement grinder pump engineered to fit into virtually any grinder pump wet well. Universal design allows easy drop-in conversion, ready to connect. The Upgrade is a complete replacement for all of the troublesome components of a centrifugal pump, including slide rails, pump/motor, float switches, piping and motor control devices.

The model TR22-A resistance thermometer is used for temperature measurement in sanitary applications. The process connections meet the stringent requirements, in terms of materials and design, of hygienic measuring locations. With increased hygienic requirements for the ambient areas around the measuring location, a stainless steel head is available in an optimised hygienic design. This enables easy cleaning of the measuring instrument, particularly for splash zones in food production. Due to the rotatable threaded connection to the connection head, it is possible to loosen the connection head and to adjust it in the desired position. The connection head can be removed together with the measuring insert. This allows the resistance thermometer to be calibrated along with the whole measuring chain, i.e. without disconnecting the electrical connections. In addition, this avoids having to open the process, and thus the risk of contamination is minimised. The spring-loaded measuring insert guarantees the contact between the sensor tip and the bottom of the protection tube and thus ensures a fast response time and high accuracy. The welded junction between the protection tube and the flange makes the use of a sealing as additional material in those areas redundant which are in contact with the product. Special features - Simplified calibration through removable measuring inserts - Materials and surface finish quality in accordance with the standards of hygienic design - Stainless steel head in optimised hygienic design, easily cleanable in all mounting positions (patent, property right: GM 000984349) - Pt100, 4 … 20 mA or HART® protocol

KWR assists the water sector in realising the transition to a circular economy. We provide support in the development and implementation of measures such as - reductions and savings in raw-material and energy use, - the use of alternative resources, such as bio-based materials, and - the recovery and reuse of materials in and outside of the water cycle, so that emissions into the environment are reduced. Through practice-oriented research, KWR contributes to the development of circular solutions and to the integration of such solutions into society.
