A fluid conductor that consists of pipe, possibly also including pumps, valves, and control devices, intended for conveying liquids, gases, or finely divided solids.

A bellows that is a flexible corrugated tubular element providing axial and radial flexibility and pressure containment.

a raised level surface on which people or things can stand.

An actuator that is intended to be operated by pneumatic power.

An electric cable intended for transmission of electric power.

A physical object intended to supply electric power according to specified levels and tolerances.

A physical object that adds or removes mechanical energy to a fluid, either constantly or periodically.

Is a civil structure and mechanical system built to collect, store, and utilize stormwater or surface runoff.

A physical object that can be any electrical device, usually incorporating an electromagnet, whereby a current or signal in one circuit can open or close another circuit.

Is a water treatment facility that uses a membrane filtration process to remove ions, molecules, particles and salts from source water by applying pressure to force water across a semipermeable membrane, producing purified water and a concentrate reject stream.

A physical object that is a totally sealed, gas-insulated compact switchgear unit. The primary switching devices can be either switch disconnectors or fused switch disconnectors or circuit breakers.

Is an air handling system that integrates components for heating, ventilation, air conditioning and filtration into a single self-contained cabinet to condition and deliver air to interior zones.

A shower intended for emergency situations.

Is a waste management facility where solid waste is isolated from the environment through engineered methods such as lining the base to prevent leachate seepage and covering disposed waste with layers of soil to reduce the risk of contamination.

Is a filtration device used to remove coarse solids, debris, algae, aquatic weeds, fish, and floating solids from raw water entering a municipal or industrial water treatment plant.

A compactor is a machine or mechanism used to reduce the size of waste material.

A 'device' intended to separate different types of substances.

Is a facility containing pumps and equipment for moving sewage from lower to higher elevation, particularly where the elevation of the source is not sufficient for gravity flow.

A detectable transmitted energy (e.g. voltage, current, pneumatic or magnetic field strength) by which information can be transmitted.
