In the ideal case, a sewer system is completely gravity-powered, like a septic system. Pipes from each house or building flow to a sewer main that runs, for example, down the middle of the street. The sewer mains flow into progressively larger pipes until they reach the wastewater treatment plant. A sanitary sewer or foul sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to treatment facilities for disposal. Sanitary sewers are part of an overall system called a sewage system or sewerage. Sewerage is that important to remove sewage from your locality, and specifically away from any drinking water source, either to a septic tank or treatment works. It is the most fundamental basic need to maintain a healthy civilised culture. The loose term drainage covers many facets. Highway drainage removes water from a road so that it’s safe to drive. Land Drainage removes swamp or salty water to allow farming or building, irrigation (a form of drainage) allows the same, Foul sewerage drainage performs the obvious removal of human or animal waste as above. Roof drainage takes water away from a building to prevent damp living conditions. What is the difference between sewage and sewerage? Sewage is the waste matter carried off by sewer drains and pipes. Sewerage refers to the physical facilities (e.g., pipes, lift stations, and treatment and disposal facilities) through which sewage flows.
Stormwater systems. Rainwater tanks are a great way to keep your garden green when water restrictions are in place. The flow of the rainwater is typically off roofs, down drainpipes, through ground drainage, into underground pipes or other drainage systems and eventually into stormwater discharge drains. It’s a network of structures, channels and underground pipes that carry stormwater (rain water) to ponds, lakes, streams and rivers. The network consists of both public and private systems. It’s an integral part of the system in your area that is designed to control the quantity, quality, timing and distribution of storm runoff. It's becoming increasingly common to collect rain water for re-use - either in the garden, or treated for domestic use. Water restrictions in recent years, and a general push towards sustainability and self-sufficiency have led to a big increase in the number of people installing domestic tank systems, even if only to water their plants with.
GASFITTING AND GAS SERVICING WORK
Gas appliances can vary in size, operating pressure and complexity, ranging from small domestic gas space heaters to large industrial steam boilers or industrial furnaces. Victoria’s Gas Safety Act 1997 defines gas appliances as either Type A or Type B. Gas fitting work with these two types differs in nature, complexity and risk. For this reason, gas fitters need to be qualified for and experienced with the type of appliance on which they are working. Experienced Gas fitting plumbers typically do the following work with Type A appliances: Installing and testing LPG and natural gas fitting lines. Installing and commissioning Type A gas appliances – for example, hot water services, space heaters, Ducted heating units, gas stoves and cooktops. Providing for adequate ventilation when installing one or more Type A gas appliances. Installing flues through ceilings and roofs constructed of different materials, with appropriate clearances and flue termination.
IRRIGATION IS THE ARTIFICIAL APPLICATION OF WATER TO THE LAND OR SOIL. IT IS USED TO ASSIST IN THE GROWING OF AGRICULTURAL CROPS, MAINTENANCE OF LANDSCAPES, AND REVEGETATION OF DISTURBED SOILS IN DRY AREAS AND DURING PERIODS OF INADEQUATE RAINFALL. ADDITIONALLY, IRRIGATION ALSO HAS A FEW OTHER USES IN CROP PRODUCTION, WHICH INCLUDE PROTECTING PLANTS AGAINST FROST, SUPPRESSING WEED GROWTH IN GRAIN FIELDS AND PREVENTING SOIL CONSOLIDATION. IN CONTRAST, AGRICULTURE THAT RELIES ONLY ON DIRECT RAINFALL IS REFERRED TO AS RAIN-FED OR DRYLAND FARMING. IRRIGATION SYSTEMS ARE ALSO USED FOR DUST SUPPRESSION, DISPOSAL OF SEWAGE, AND IN MINING. IRRIGATION IS OFTEN STUDIED TOGETHER WITH DRAINAGE, WHICH IS THE NATURAL OR ARTIFICIAL REMOVAL OF SURFACE AND SUBSURFACE WATER FROM A GIVEN AREA. IRRIGATION HAS BEEN A CENTRAL FEATURE OF AGRICULTURE FOR OVER 5000 YEARS, AND WAS THE BASIS OF THE ECONOMY AND SOCIETY OF NUMEROUS SOCIETIES, AROUND THE WORLD.
MECHANICAL SERVICES PLUMBING SYSTEMS
Mechanical services plumbing work involves mechanically heating, cooling and ventilating residential and commercial buildings. It also includes plumbing work for medical gas equipment. The work is highly specialised and technical.
