We understand there's a lot of terminology that can be confusing. So we've taken the time to define some of the most common terms that we think our clients should know!

Artificial Intelligence (AI) Intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and other animals.
Autonomous Cable-less multi-sensor pipeline inspection with integrated leak detection
Biofouling Fouling of underwater pipes and other surfaces by organisms such as barnacles and algae.
Biomimicry The design and production of materials, structures, and systems that are modelled on biological entities and processes.
Cryptosporidium Parasitic coccidian protozoan found in the intestinal tract of many vertebrates, where it sometimes causes disease.
Digital Twin A digital replica of physical assets, processes and systems that can be used for various purposes.
Disinfection Removal or inactivation of pathogens in water by chemical treatment.
Dosing To blend with another substance. Often using sodium bisulphate to dechlorinate chlorinated water, or using chlorine to raise chlorine PPM in water.
Hydrocarbon A class of organic compounds containing only hydrogen and carbon. Presence of hydrocarbons in water is indicative of water quality.
Inspection Inspection refers to formal examination and evaluation of an area, system or component for flaws or defects.
Lining Linings are structural epoxy pipes adhering to the interior of pipes to protect the surface from corrosion and to prevent the leaking of fluids.
Potable Water Water which is safe to drink.
Rehabilitation Restore or rebuild something – whether man-made or within a natural environment – to its previous condition.
Sediment Material that settles at the bottom of a liquid. Within natural environments, sediment is generally that material comprised of dirt or sand.
Service Reservoir Service reservoirs store fully treated potable water close to the point of distribution.
Sludge Sludge refers to a wet, viscous substance which is a mixture of solid and liquid components.
Snagging Checking a new structure for minor faults that need to be rectified.
Stagnation Water stagnation occurs when water stops flowing. Stagnant water can be a major environmental hazard.
Stratification When water masses with different properties - salinity, oxygenation, density, temperature - form layers that act as barriers to water mixing.
Trenchless A type of subsurface construction work that requires few trenches or no continuous trenches.
Trihalomethanes (THMs) Chemicals formed along with other disinfection by-products when chlorine/disinfectants react with naturally occurring matter in water.
Water Disinfection By-Products Some disinfection methods leave residue in the water, others can combine with organic matter to create tri-halomethanes, known carcinogens.
Water Quality Control A process defined to monitor, report, and act on information relative to maintaining a prescribed quality of water; may be automated.
Water Treatment Plant Facilities designed for the filtration and disinfection of a water supply
