Realisation GTD: first activities

Construction and realisation

Aardyn is responsible for the construction of the geothermal wells on behalf of GeoThermie Delft (GTD). Aardyn is working on similar projects at several locations in the Netherlands. Working safely, clean and carefully is paramount during drilling, extraction and research.

The source will be located on Rotterdamseweg, next to the combined heat and power plant, opposite of the Nieuwe Haven.

We are finally there: if everything goes well, contruction will start at the end of May!

Plant preparation

Before the well can be drilled, the site is prepared for construction. Among other things, pillars will be placed in the ground and a liquid-proof floor will be installed. Then the conductor is placed: an extra protective sleeve for the freshwater layers. Next, the drilling rig and the auxiliary installations are built. Drilling two wells about 2.2 km deep will take about three months and will continue 24 hours a day, seven days a week. Each well is tested and the test water is temporarily collected in nearby basins. Dissolved formation gas is brought up with the pumped water, which is captured, upgraded to natural gas and added to the gas network in the combined heat and power plant (CHP). The wells are reinforced with steel pipes, which are secured with cement. 

Piling

Placement of construction canvas

Installations

The installations necessary for pumping, transporting and injecting the water will be housed in the CHP building. Finally, the covered wells, the installation to separate gas and liquid and a number of supply and discharge pipes remain visible after the drillings. 

Accessibility, liveability and safety

Geothermie Delft is committed to preventing and limiting nuisance in the areas of accessibility, liveability and safety. By accessibility we mean: traffic safety, traffic nuisance, accessibility. Liveability concerns, for example, noise, light and odor nuisance. And safety is about the circumstances for people and the environment. All activities meet the requirements of the environmental permit in aspects of noise, safety and traffic. For example, a transport plan, noise and vibration measurements, noise barriers and traffic controllers on the construction site are provided. The project also provides sufficient information and a telephone number that can be reached 24/7. We will also continue to talk to residents and companies about their interests, questions and concerns.
