Delfland presents its 2026 budget under the motto: “A solid foundation, with an eye to the future.” At a time of rising energy, maintenance, and personnel costs, the water board is opting for cost-saving and robust solutions.
The Netherlands and water are inextricably linked. But strong dikes, clean ditches, and pure water are essential for a safe environment. At the Delfland Water Board, we take responsibility for water management. This ensures that you, along with all the residents of our region, can enjoy living, working, and relaxing in this beautiful water-rich environment.
The 2026 budget outlines the water board’s plans for the coming year and their associated costs. The budget was prepared with financial stability and social impact in mind. Water board member Peter Ouwendijk, responsible for finances, explains: “The choices in this budget align with the 2023-2027 coalition agreement and ensure that Delfland can continue investing in water safety, water quality, climate adaptation, and efficient wastewater treatment. This will limit the increase in water board taxes.”
Water quality remains a point of attention
The quality of surface water is still inadequate. “In 2026, we will continue to focus on improving surface water quality,” says Peter Ouwendijk. “Close collaboration with the greenhouse horticulture sector is key. Ultimately, we are all responsible for good water quality. Clean water is important to all of us. Especially now that we are increasingly facing shortages and drinking water companies are having to rely more frequently on surface water.”
The water system is under pressure
Responding to climate change will remain a high priority in 2026. Due to increased heavy rainfall, the current system of ditches, canals, and pumping stations is finding it increasingly difficult to process this water. Delfland wants to improve the area’s capacity to effectively collect and/or drain rainwater. This will be achieved by researching suitable locations for rainwater collection, and by constructing and renovating pumping stations to maintain water levels and flow.
Maintenance and innovation in wastewater treatment
Maintenance and modifications to the wastewater treatment plants are necessary in the long term to ensure we can continue to effectively treat wastewater from residents and businesses. A key development in this regard is the recovery and reuse of raw materials and energy. This is necessary, for example, to make the treatment plants energy-neutral in the long term. The arrival of the new wastewater treatment plant in Vlaardingen also requires investment.
A critical look at the expenses
“To achieve these ambitions, we’ve critically reviewed our expenditures,” says Peter Ouwendijk. “Where possible, we’re postponing work or carrying it out more efficiently, without compromising quality. We’re assessing whether collaboration with other organizations is still necessary. Delfland is also exploring how artificial intelligence can simplify the work. Furthermore, we’re saving money to limit future rate increases, while still allowing room for investment. In short, the 2026 budget demonstrates that Delfland is choosing a robust course: we’re investing in a safe, clean, and climate-resilient area, with an eye for affordability and a resilient region.”
