Dewatering Services
Dewatering
When water has collected in excavations and trenches, it needs to be removed before works can progress. Dewatering presents a distinct set of practical challenge requiring clear, outcome-focused thinking that require careful planning and the right water treatment solutions.
Unlike surface water management, dewatering in construction usually involves more predictable flow rates – making it easier to tailor treatment systems to the task. However, understanding how silts and suspended solids behave under pumped conditions is key to designing effective and compliant systems.
Choosing the right dewatering method early in a project helps keep the programme on track and avoids costly delays due to regulatory breaches or poor water quality discharge.
Here at Frog Environmental, we have extensive experience in supporting contractors with practical and cost-effective, practical dewatering strategies. Our solutions that balance performance, simplicity and sustainability are designed to be easy to implement, adapt to your site, and deliver regulatory compliance and environmental stewardship with confidence.
Solutions
Solutions for dewatering challenges
Working with
Pollution prevention at the point of pumping
We integrate water treatment at the point of pumping, helping to capture suspended solids before they travel downstream. By the time water reaches a ditch, tank, or settlement area, much of the silt has already been managed – reducing risk and improving efficiency.
Mobile water treatment for dynamic sites
Our modular, mobile treatment systems move with your works, supporting phased construction or linear progressions. This adaptability helps maintain regulatory compliance and environmental stewardship throughout the shifting layout of a live site.
Flexible silt capture solutions
We offer a range of capture options including dewatering bags, settlement tanks, and custom-lined ditches. Whether using site-based resources or integrating proprietary systems like our Silt Capture Channel or Pipe Reactor with Clearflow Gel Flocculant, we tailor the solution to suit your site constraints.
Cost-effective treatment strategies
Our experience allows us to match the right technology to the specific challenge, maximising return on investment while meeting tight environmental controls. We design with practicality and affordability in mind.
Training and on-site support
We offer silt and dewatering training to upskill teams and build capacity and confidence, helping site teams understand and apply best practice. Our support helps teams ‘get it right on site’ from the start, reducing delays and rework.
