Lowflo’s Reservoir Survey & Leak Detection services consist of a full inspection both visually and non-invasively utilising technically advanced NDT equipment. Inspection surveys are necessary to assess the integrity of the structure and to prevent surfaces in contact with water from deteriorating or breaking down without being noticed.
Typical Reservoir Surveying includes:
Lowflo offer a complete Reservoir Leak Detection service using dive crews professionally trained in confined space entry and under water leakage and repairs. Decontamination protocols are enacted prior to any diver or equipment entering the tank using a solution of sodium hydrochlorite. Diver’s complete this task using a food grade fine particulate material in a squeeze bottle and meticulously follow floor joints to mark the location of leaks and apply the approved epoxy via hand trowel into located leak areas. Cable management is of particular importance as diver’s need to navigate around structural pylons, supporting the structure, to perform the inspection and repairs.
Lowflo provides detailed reports on the internal and external condition of the reservoir as part of our initial survey works. These reports include the initial assessment of the reservoir and list out recommendations on any works required to bring the structure up to a standard (BS8558).
When hydrolytic corrosion occurs on internal surfaces, this can lead to concrete and steel corrosion and leakage of treated water, resulting increased risk of bacteria.
Lowflo’s refurbishment of reservoirs and towers can results in significant improvements in water quality, prevention of water leakage and consequential cost reduction in chemical dosage of water.
Typical refurbishment includes:
