An agricultural irrigation reservoir in Panama had been losing storage capacity due to years of sediment buildup at the bottom. The reservoir management decided to bring in mechanized dredging equipment. After comparing several options, they chose YG Machinery’s intelligent dredging robot. This smart dredging solutions package, designed specifically for reservoir conditions, has been running for 3 months now. This article covers the project requirements, equipment selection, and operating results.

Customer Needs: What Challenges Did the Reservoir Dredging Face?
The Panama customer’s main need was to remove sediment from an agricultural irrigation reservoir. Here are the specific conditions:
- Heavy sediment buildup: The reservoir has been in operation for 10 years. Upstream sediment has been depositing continuously, with sludge thickness reaching 1.5–3 meters at the bottom, and over 5 meters in some areas. Effective storage capacity dropped by nearly 30%, directly affecting dry-season irrigation water supply.
- Special operating environment: The reservoir covers about 50 hectares, with water depth varying from 3 to 12 meters. There are intake and outlet pipes inside the reservoir area. Traditional dredging boats have trouble reaching corners and edges, and the water supply cannot be completely stopped during dredging.
- Strict environmental requirements: The reservoir is the only irrigation water source for downstream farmland. The dredging process cannot cause secondary water pollution, and the sludge must be properly handled without random dumping.
- High labor costs: Local labor costs in Panama are high, and underwater work has safety risks (deep water, low visibility, changing water temperatures). The customer wanted a mechanized solution to reduce operational risks.
The customer needed a sludge cleaning robot system that could be operated remotely, work efficiently, and meet environmental standards. The equipment also had to handle the hot, humid tropical climate and support long continuous operation.


YG Solution: How the Intelligent Dredging Robot Handled the Customer’s Conditions
Based on the Panama customer’s reservoir dredging needs, YG recommended the YG-800 model intelligent dredging robot, with a complete set including underwater unit, workstations, and post-processing equipment, forming an integrated “dredging – conveying – treatment” solution:
Full hydraulic power system, built for tropical environments: Uses a closed-loop hydraulic circuit design, operates in -20°C to 60°C conditions, and runs 24/7 without overheating. Panama has year-round high heat and humidity, and the YG equipment handles it perfectly. It also saves about $11,000 per year in electricity costs per unit (based on local power rates).
Underwater visual monitoring for precise operation: Equipped with an underwater camera that sends back real-time 1080P HD video. The operator can clearly see the bottom conditions from the on-shore control room, avoiding accidental damage to intake and outlet pipes during blind dredging.
Modular work unit for complex sludge types: The hydraulic auger speed is adjustable from 0–200 rpm and can break up compacted sludge and gravel up to 40 mm in size. The piston slurry pump has a 30-meter head, capable of sending bottom sludge to on-shore treatment equipment over long distances.
Wireless remote control, no personnel in the water: The operator controls the robot’s movement, working position, and efficiency from the shore via a wireless remote. No one ever enters the water, completely eliminating the safety risks of deep-water operations.
Post-treatment system for solid-liquid separation: With supporting equipment like filter presses, the dewatered sludge volume is reduced by 50%, cutting transportation costs in half. At 200 m³ per day, this saves over $27,000 per year in transport fees.
From equipment selection and solution design to shipping and commissioning, YG engineers followed through the entire process. The system was delivered and put into operation in just 20 days.
Customer Feedback: Data-Driven Results
Here is the actual data from the YG-800 sludge cleaning machine after 3 months of operation at the reservoir:
- Dredging efficiency: Handled 200–250 m³ of sludge per day, over 3 times faster than traditional dredging boats.
- Labor costs: Previously required 8–10 divers plus support staff. Now only 2 operators are needed, reducing labor costs by 70%.
- Safety: Zero personnel entered the water and zero safety incidents, eliminating the risks of deep-water operations.
- Environmental compliance: After solid-liquid separation, clean water returned to the reservoir. The dewatered sludge was used to improve soil on surrounding farmland. No secondary pollution occurred.
- Equipment reliability: Ran continuously for 3 months with a failure rate below 2%. The hydraulic system performed stably under high-temperature conditions.
Customer comment: “Before, we had to hire divers to do the dredging work. Labor costs were high, and deep-water operations were a real safety concern. After using YG’s sludge cleaning machine, the operators stay on the shore with remote controls, so we don’t worry about safety anymore. The dredging efficiency is much faster than before, and the bottom is cleaned more evenly. The equipment has been running for 3 months now and has been stable overall. We’ve regained some storage capacity, which helps with this year’s irrigation water supply.”

FAQ About the Sludge Cleaning Robot
Q1: How deep can the sludge cleaning machine operate?
Maximum diving and operating depth is 30–90 meters (up to 20 meters underwater with 40% solid content for flowable sludge). Suitable for reservoirs, lakes, rivers, and various water depths.
Q2: What types of sludge can the equipment handle?
The YG sludge cleaning robot can handle soft mud, compacted sludge, sandy sludge, sludge with gravel, and other materials. The hydraulic auger can break down hard objects up to 40–60 mm, and the slurry pump can convey high-concentration mud.
Q3: Is transportation and installation complicated?
The robot body weighs only 500 kg (for YG1200 Electric as an example). The power station and control cabinet are modular. A standard shipping container is enough for transport. On-site assembly and commissioning can be completed within 2 hours after arrival.
Q4: Can the equipment handle hot tropical environments?
The full hydraulic power system works in -20°C to 60°C conditions and runs 24/7 without overheating. YG equipment has been operating stably in dozens of tropical countries and is fully adapted to Panama’s hot, humid climate.
Q5: Does the sludge cleaning machine need regular replacement of wear parts? How long is the maintenance cycle?
The hydraulic auger breaker head should be checked for wear every two weeks and replaced based on actual usage. The slurry pump impeller and seals can run 800–1,200 hours under normal conditions. A full maintenance check is recommended every quarter. During the first 3 months of the Panama project, only one breaker blade was replaced, and maintenance costs were much lower than expected.
