ROV Spot Sampling

Effective drinking water management is crucial for public health, and frequent quality testing is a non-negotiable standard. Yet, hidden challenges persist—particularly in service reservoirs, where low turnover spots often remain unmonitored. These stagnant water zones can jeopardise water quality, fostering bacterial growth, sediment accumulation, and biofilm formation.

What Are Low Turnover Spots?

Low turnover spots are areas in water reservoirs where minimal water movement occurs, resulting in stagnation. These locations, often found in corners or areas far from inlet pipes, are susceptible to sediment accumulation, microbial colonisation, and contamination.

Key characteristics of low turnover spots include:

  • Stagnation: Poor water circulation allows contaminants to settle.
  • Contamination Risk: Reduced disinfectant levels make these areas prone to bacterial growth.
  • Hard-to-Reach Locations: Often inaccessible for traditional sampling methods.

Challenges in Traditional Water Sampling

Standard water quality testing methods often rely on samples from taps or easily accessible points. While these locations are convenient, they may not reflect the true conditions in low turnover spots, where contamination risks are higher.

  • Inability to access critical zones within reservoirs.
  • Sampling from areas with high circulation, yielding incomplete data.
  • Overlooking microbial build-up and sediment-related contamination.

Precision at Every Point

Remote Operated Vehicles (ROVs) offer a groundbreaking solution to monitor and sample water in hard-to-reach areas of service reservoirs.

Their innovative features provide accurate, detailed insights, helping water management professionals maintain high-quality drinking water.

Targeted Water Sampling

ROVs can navigate directly to specific low turnover spots, collecting water samples for precise chemical, physical, and microbial analysis.

Sediment Collection

Equipped with specialised tools, ROVs can gather sediment samples for laboratory testing, ensuring a comprehensive understanding of reservoir conditions.

Visual Inspections

High-definition cameras on ROVs enable detailed visual assessments of reservoir interiors, revealing structural issues, wall lining conditions, or potential ingress/egress.

Microbial Monitoring

Advanced attachments allow ROVs to detect and sample for bacterial contamination directly within low turnover zones.

Advantages of ROV Spot Sampling

ROV technology offers unparalleled benefits for reservoir management:

  • Rapid Deployment: Requires minimal manpower and can be deployed quickly, especially during emergencies.
  • Non-Disruptive: Eliminates the need to decommission, drain, or clean reservoirs for inspections.
  • Comprehensive Coverage: Accesses areas beyond the reach of traditional sampling methods.
  • Future-Ready: Integration with AI and machine learning opens possibilities for real-time data analysis and automated reporting.
