New Stormwater Retention Basin in Neulingen-Goebrichen: Cost, Capacity, and Impact on Bruchbach Erosion
Construction commencement in Göbrichen: initiatives for a fresh water collection system kick off
In a significant move towards flood prevention and environmental protection, the groundbreaking ceremony for a new stormwater retention basin took place in Neulingen-Goebrichen on Tuesday. The project, which is expected to cost 2.6 million euros, aims to reduce the amount of water flowing into the Bruchbach, thereby addressing concerns about erosion and potential flooding.
Purpose and Context
The retention basin is designed to manage stormwater runoff from the Neulingen-Goebrichen area. Its objective is threefold: to reduce flooding risks, improve water quality, and prevent soil erosion along the Bruchbach stream. The basin helps control the volume and flow rate of stormwater entering the Bruchbach, which has experienced increased erosion due to urbanization and more frequent heavy rains.
Cost
The cost of the retention basin project typically covers planning and design fees, excavation and construction of the basin, installation of inflow and outflow control structures, landscaping and stabilization of the basin edges, and monitoring and maintenance provisions. Estimated costs for similar stormwater retention basins range widely depending on size and complexity, but a mid-sized basin project can cost anywhere from €200,000 to €600,000. Funding might come from municipal budgets, regional environmental grants, or collaboration with local water management authorities.
Capacity
The capacity of the retention basin is a key factor. Typically designed to hold runoff from a specific storm event, e.g., a 5-year or 10-year storm, the basin in Neulingen-Goebrichen is expected to hold approximately 7,300 cubic meters of stormwater. This capacity regulates the release of stormwater slowly to prevent sudden surges downstream in Bruchbach.
Impact on Bruchbach Erosion
Before construction, the Bruchbach has been subject to erosion due to increased stormwater runoff velocity and higher peak flows caused by impermeable surfaces in urban areas. The retention basin is expected to reduce peak discharge rates into Bruchbach, lowering flow velocity. This, in turn, will stabilize the stream banks and minimize sediment transport. The improvement in ecological status will prevent habitat destruction from erosion. Over time, this intervention helps restore natural streambed stability, reduces sediment load downstream, and minimizes damage to infrastructure near Bruchbach.

The new stormwater retention basin in Neulingen-Goebrichen, designed for flood prevention and environmental protection, has a purpose rooted in managing climate change impacts, as it aims to reduce flooding risks, improve water quality, and prevent soil erosion along the Bruchbach stream. Scientists in the field of environmental science believe that this intervention will help restore natural streambed stability, reducing sediment load downstream and mitigating damage to infrastructure due to increased weather events such as heavy rains.
