Soil Suitability for Geothermal Heat Pumps (Closed-Loop Horizontal Residential)

Ground source heat pump systems provide a viable alternative to conventional heating and cooling systems in the move towards sustainable building solutions. The most important factor for successful operation of a ground loop heat system is the rate of heat transfer between the pipe and surrounding soil.

Techniques for Sewer Condition Assessment

Zoom cameras Closed-circuit television Digital scanners Laser profilers Remote sensing diagnostic techniques Zoom cameras Cost and time saving preliminary inspections 
 Main premise is that most of sewer problems occur at or near maintenance holes 
 Provide good quality imagery up to 20-75 m pipe length Able to survey 150 to 1525 mm diameter sewers 
 Colour videos and digital images saved on optical storage devices

Factors Affecting Selection of UUL Technologies

Every underground utility locating technology has its own limitations. 
There is no single technology that can be used for every type of utility, soil type, and site. Many factors, including characteristics of expected underground utilities, geological conditions at the site, environmental and social factors, and experience of the operators should be considered as criteria for the appropriate selection of technologies.

Underground Utility Locating Technologies

The most widely used approach for wastewater pipelines condition assessment is to define condition states based on a set of variables collected by visual inspections. A state is defined as “a combination of specific level of variables that provides a complete description of the dynamic behavior of the system”. The current condition of an asset and its likely rate of

Reasons for Infrastructure Deterioration

The under investment in public works programs; 
 The lack of good management systems for infrastructure; 
 Failure to recognize the importance to the future economy of maintaining a sound physical infrastructure; 
 Cut-backs that have slashed public-works budgets; 
 Failure to replace the infrastructure as fast as it wears out; 
 failure to realize that lack of physical infrastructure

Types of Infrastructure in Urban and Rural Areas

Transportation, Water and Waste water, Waste Management, Energy production and distribution, Buildings, Recreation facilities, Communication. Transportation: Ground transportation (roads, bridges, tunnels, railroads) 
 Air transportation (airports, heliports, ground facilities, air-traffic control) 
 Waterways and ports (inland waterways, shipping channels, terminals, dry docks, sea
