Water Treatment and Reservoir Foundations

Aarsleff's Experience

Aarsleff Ground Engineering has delivered works for a variety of water treatment and reservoir foundations across the UK’s infrastructure sector. From small-scale treatment plants to major reservoir expansions, our team has the expertise and equipment to handle complex geotechnical challenges.

We have partnered with water authorities, contractors, and engineering consultants to design and deliver cost-effective, time-efficient solutions tailored to each project’s ground conditions and performance requirements.

Our in-house design and estimating teams work closely with clients from the early design stages, providing geotechnical assessments, value engineering, and buildability advice. This proactive approach ensures that our clients benefit from a fully integrated and streamlined construction process.

Piling Techniques

Piling plays a fundamental role in supporting the heavy structures associated with water treatment facilities and reservoirs. Aarsleff provides a range of piling techniques suitable for a variety of soil conditions and structural demands, including:

Our precast concrete piling systems are particularly advantageous in water treatment environments due to their high durability, fast installation speed, and minimal spoil generation. These attributes are essential in projects where environmental sensitivity and operational continuity are paramount.

Retaining Wall Solutions

Retaining structures are often required to support excavations, tanks, and earthworks in reservoir and treatment plant developments. Aarsleff designs and installs a range of retaining wall solutions, including:

Each solution is tailored to the site’s specific geotechnical conditions and functional needs. We focus on safety, longevity, and constructability, ensuring the retaining systems provide reliable performance under varying load and environmental conditions.
