Wuhan is the capital city of Hubei province in central China and has 166 lakes that cover 2,217 square km (856 square miles) and approximately 25% of the city. This surface water coverage is one of the world’s highest.
The Wuhan Environmental Protection Bureau (WHEPB website: http://www.whepb.gov.cn) is responsible for monitoring the surface water quality within the city borders and does this by monitoring a subset of 50 lakes on a yearly basis for temperature, conductivity, pH, dissolved oxygen and turbidity. Before using the Oceanalpha ESM30 Water Quality Sampling & Monitoring Boat, WHEPB needed three months to do this by taking a manned boat into each lake.
The Oceanalpha ESM30 Water Quality Sampling & Monitoring Boat works autonomously based on GPS waypoint navigation that a user programs with a portable control station from the shore. The boat contains a multi-parameter sonde connected to a flow cell and an on-board pump. Using the ESM30, WHEPB surveyed 50 lakes in 14 days for a 640% improvement in efficiency. As an additional safety benefit, workers did not need to go onto the water.
