When the City of Canyon, Texas, needed to evaluate the effectiveness of a new aeration system and manage rising sludge levels, they turned to Hydrasurvey for an independent sludge survey. Using advanced sonar and a precise data collection process, Hydrasurvey delivered a 3D sludge map that revealed no immediate need for dredging—saving the city significant costs and validating their infrastructure investment. This case highlights the value of third-party sludge measurement in helping Texas municipalities make informed, cost-effective decisions without relying on potentially biased recommendations from dredging contractors.
