Bioretention Swale - A bioretention swale is a swale with a bioretention system installed in its base.

Bioretention System - A Bioretention System is a system that uses vegetation to reduce downstream flow velocities and subsequent drain sizes whilst facilitating treatment. Bio-retention systems combine various Water Sensitive Urban Design (WSUD) treatment types in one 'treatment train'. A system is designed to carry out primary and/or secondary treatment processes of stormwaters and retard flows. This retention or retardation can enable sediments to precipitate out of the water taking along with it some pollutants. The use of biological processes to 'treat' stormwater whilst facilitating conveyance and retention gives rise to the title of Bio-retention.

Bio-Retention System - A Bio-Retention System is a well-vegetated, retention cell or pond designed to enhance water filtration through a specially prepared sub-surface sand filter. Bio-retention cells may be incorporated into grass or vegetated swales or may be a stand-alone treatment system. The system incorporates vegetation with medium-term stormwater retention and sub-surface filtration/infiltration.

Biosolids - Biosolids is sewage sludge that has been treated to reduce disease causing pathogens, thus becoming suitable for beneficial reuse. Biosolids have been used in:

Bitumen - Bitumen is a very viscous liquid or a solid, consisting essentially of hydrocarbons and their derivatives, which are soluble in carbon disulphide. It is substantially non-volatile and softens gradually when heated. It possesses waterproofing and adhesive properties. It is obtained from native asphalt or by processing the residue from the refining of naturally occurring crude petroleum. Bitumen is used in the construction of Sprayed Seals.

Bitumen Seal - Bitumen Seal -> Sprayed Seal

Black Water - Black water is water which contains human, food or animal waste.

Block Cracking - Block Cracking is a series of interconnecting cracks that form in a roughly rectangular pattern. It can occur in both concrete and flexible road pavements.

Blow Out - A blow out commonly occurs in pressure pipes due to corrosion pitting in metallic pipes.

Blower - A blower is a piece of machinery used to force air to flow from one point to another.

Boardwalk - A boardwalk is a raised typically wooden pathway designed for use by pedestrians and cyclists. Boardwalks are often found along beaches, but they are also common as paths through wetlands, coastal dunes, and other sensitive environments.

Boat Ramp - A Boat Ramp is a structure for loading & unloading boats. A boat ramp provides a trafficable sloping surface that transitions from land to water and allows boats on trailers to be backed into the water and launched.

Boating Facility - A Boating Facility is any facility constructed for boating purposes, such as a pontoon, boat ramp or jetty.

Bollard - A bollard is a post designed to act as a barrier to traffic.

Boom Gate - A boom gate is a bar, or pole pivoted in such a way as to allow the boom to block vehicular access through a controlled point. It is generally electric motor driven and commonly has a system of vehicle detection for closing and authorised entry detection such as a card reader for opening.

Booster Pump Station - A Booster Pump Station is a pump station designed to boost the pressure of water within a long pipeline. Typically they would be used to boost low reticulation pressure in areas of higher elevation but can also be used to boost pressure in long transfer mains.

Border Road - Border Road -> Boundary Road

Bore - A Bore (or more specifically a Ground Water Bore) is a shaft constructed to extract water from an aquifer. If the water flows to the surface without the need for a pump, then the bore is called an artesian well.

Bore Pump Station - A Bore Pump Station is a water pump station designed to extract water from an aquifer.

Boundary Road - A Boundary Road is a road located on the boundary between municipalities.

Box Culvert - A Box Culvert is a П-shaped reinforced concrete structure used in civil engineering works, including; drainage and road works. Box culverts are most commonly used as an alternative to drainage pipes where design constraints limit the amount of cover available, but are also used in the construction of of a range of other assets including; pedestrian underpasses.

Breakdown Maintenance - Breakdown Maintenance is maintenance that is performed on an asset after it has failed.
