The HDDW method is highly suitable for the construction of an ATES system.
Choosing for an HDDW means choosing for the possibility to construct an ATES system:
- …With a high capacity per source
The (artificial) screen prevents sand delivery and keeps the inflow and outflow of water from and to the filter pipe at an optimum level. This ensures a high capacity per source.
- …Underneath existing buildings and infrastructure
The big advantage of horizontal directional drillings is the possibility to drill beneath buildings and infrastructure. As a result, an ATES system can be constructed in many more places, including existing residential areas.
- …At low costs
The high capacity per source means that the capacity remains the same while the number of sources can be decreased. As a result, fewer drillings are required for the construction of an ATES system, and fewer (pump) installations. This means a reduction in the investment, energy and maintenance costs.
- …In a thin aquifer
The horizontal position of an HDDW means that a thin aquifer is suitable for an ATES system as well.
- …That Occupies little space
Due to the reduction in the number of sources and the horizontal position, an HDDW takes up less space than vertical sources with the same capacity.
- …In many different types of soil, including contaminated soil
Because you can choose between different types of screen (natural or artificial), the HDDW can be constructed in almost any type of soil without loss of capacity or risk of clogging.
- …With a wide selection of material
The HDDW can be constructed with different types of filter pipes.
- …That is easy to maintain
The artificial screen already greatly limits sand delivery and contamination. In addition, its composition makes such a screen easy to maintain.
In short, it is a sustainable, cost-saving solution.
