Introduction

Because of climate change, soil subsidence and sea level rise, and because of population growth and increasing prosperity, the pressure on our water system is increasing. We want our water to be clean, to have sufficient water available and we certaintly want no floodings. We also want to minimize sewer overflows and limit the required capacity for our wastewater treatment plants. Finally, we want to reduce our energy costs and if possible, even generate energy from our (waste) water flows.

We often choose to raise dikes, build new pumps and dig new canals. These actions are often very expensive. Another method is to optimize the existing (waste) water system by using real-time control. This allows reduction of pollution of surface water, reduction of required capacity for wastewater treatment plants, prevention of floodings and better respons to failures in the controlled system.

Real-time control is not a new technology, but in the (waste) water management is still limited apllied. The development and implementation to encourage and share experience in being a platform developed control NEXT. This prevents the wheel reinventing. NEXT aims to control knowledge and use of RTC controls and sharing via open standards available to users.
Why Control NEXT?

Real-time control is a technique for measuring current information quickly (real time) to process it at such intakes, pumping stations, dams and pumps to handle it. By applying this technique, the (waste) water system to be optimized, thus reducing costs with greater efficiency from the (waste) water is removed.

The benefits of real-time control are:

• Cost savings through less investment in infrastructure and lower energy consumption
• A greater environmental benefit by such a reduction of CSOs organized and conserve our fragile waters.
• Disruptions in collecting system

Control What is NEXT?

NEXT Control is an open platform where knowledge can be shared and applied to the field of real-time control, from simple to very complex. These include the schemes themselves, as well as end product algorithm and its application in operational systems. All components with the Control NEXT stamp its open-source (LGPL license) and are available through the WIKI. This way we can together ensure that all developments are mutually reinforcing.
You can also participate in and discuss new arrangements.
What can Control NEXT?

NEXT is a modular control system specifically for the water sector was developed to apply real-time control in practice easier. Control NEXT is no substitute for the telemetry system, but is connected to the existing telemetry systems. NEXT Control can also be connected to weather (forecast) systems or KNMI Meteo Consult. The controls are so smart links between systems.

The controllers are in Control NEXT free at your disposal. A large number of components is now waiting for you. Use is made of standard scripting languages. This structure makes it possible to provide flexible, new controls to add. Within the Control NEXT platform if need be more than 1000 schemes independently run and control the water. It makes no difference whether the system of open water, the sewer or the water chain and / or treatment used.
Simple and complex controls

NEXT particular control is that besides simple (if-then-else, or PID) controllers, advanced state-of-the-art controls are available. These regulators are suitable for large and complex applications such as controlling an entire treatment group, complex atrial polder canals and river systems or networks with hundreds of input and output variables that are driven numerous works of art. The unique Control NEXT is that it is possible to easily start, then over time the scheme to expand both in size and complexity.
NEXT Control community

NEXT Control was established by a consortium of which science, knowledge institutions and consultants meet: TU Delft, Nelen & Schuurmans and Deltares. NEXT control structure which has an open third-party software applications can be included as the NMPC control of DotxControl.

NEXT control is fully on Delft-FEWS and Lizard and is available without licensing fees.

NEXT control is tested in practice and is used by eg Water Hollands Noorderkwartier, Waterboard Hollandse Delta and several municipalities including Purmerend, Alkmaar, Heerhugowaard and ancient links.
