Bends and Junctions
Bends The centre line effective length on bends vary depending on diameter of pipe.
111/40 221/20 450 900

Bends are manufactured by cutting pipes into two or three segments and joining them together at the required angle using an epoxy resin. Although manufactured from class H pipes, Bends are not load bearing structures and should be encased in concrete surround to carry any applied load. Manholes are normally required for inspection purposes over bends in sewers, however, there may be occasions where bends are permitted without a manhole. e.g. 90º or 45º bends immediately outside a drop manhole 111/4º Bend placed immediately outside a manhole Various Bends in Drains carrying only rainwater 150 Diameter Bends on pipes from road gully to main drain.

Junctions are normally attached to full length pipes, inlet part always being the female or socket end. Concrete surround should always be placed around a junction. Manholes are normally required at intersection of junctions for inspection purposes, however there may be occasions where junctions are permitted without the use of a manhole e.g. smaller diameter pipes from road gullies or one off houses to main drain which are usually 100 or 150 Diameter and may be P .V.C. clay pipe, or concrete pipe.

Spigot & Socket Pipes
Water test
General Site Testing Air and water tests All lengths of sewer drain up to DN 750 should be tested for leakage by means of air or water tests. These tests should be applied after laying and before backfilling. Some backfill may be placed at the centre of each pipe to prevent movement during testing. We strongly recommend that air testing be undertaken periodically during the laying process, say every fourth pipe, so as to facilitate rectification if any defect is found. Short branch drains connected to a main sewer between manholes should be tested as one system with the mains sewer. Long branches should be separately tested. Man entry sizes of pipeline can be physically inspected while smaller diameters can be visually inspected from manholes by means of T.V. cameras. Visual inspection: Check for1. obstructions and debris, 2. structural soundness of pipes, 3. joints properly sealed, 4. line and level within tolerance Pipeline under Water Test (diagram)
Level of water for test

Water Test A water test is the more logical and conclusive method of testing a completed pipeline but problems of availability and disposal of the quantity of water involved may cause difficulty. Before backfilling, leakage can be clearly located, its amount assessed and where necessary appropriate remedies applied. To test the pipeline:1. Insert plugs in both ends of the drain or sewer and in connections if necessary. Precautions should be taken by strutting or otherwise to prevent movement of the drain or sewer during testing. 2. Fill the system with water ensuring all the air has been expelled. 3. Allow at least two hours before test readings are taken to allow conditions to stabilise, adding water to maintain the test head. It may be necessary to extend this period for large diameter pipes, up to twenty-four hours or more before a stable condition is reached. 4. Apply required test head at the upper end by means of a flexible pipe leading from a graduated container or stand pipe. 5. Apply the test pressure of 1.2m head of water above the soffit of the drain or sewer at the high end with a maximum of 6m head at the low end. If it exceeds 6m test the drain or sewer in stages. 6. Measure the loss of water over a period of 30 minutes by adding and metering quantities of water at intervals of 5 minutes to maintain original water level in the standpipe. Over this 30 minute period the quantity of water added should not exceed 0.05 litre per 100 linear meters per millimetre of nominal size of the drain or sewer, i.e. for a 150m length of DN 800 the allowable leakage would be:
1.2m Head of Water (6.0m Max at lower end)

0.05 x 150 x 800 = 60 litres ----100 Should the pipeline not comply with these requirements it will probably be attributable to one of the following:1. leakage from test equipment 2. trapped air, 3. leakage from joints, e.g., displaced ring, 4. leakage from damaged or defective pipe.

Spigot & Socket Pipes
Air testing
Air Test The air test is very searching and is more convenient than the water test, but the leakage rate cannot be measured accurately. An excessive drop in pressure in the air test may indicate a fault in line such as a displaced sealing ring. It may be due to faults in the testing apparatus. Therefore the first check must be on the apparatus, especially the seals of the stop ends and all connections. The point of any leakage may be difficult to detect but spraying with soap solution could indicate such leakage by the presence of bubbles. Failure to pass this test in not conclusive and, when marginal failure does occur, a water test as described should be made and the leakage rate determined before a decision as to rejection is made. Air test requirements are currently specified in British Standard Codes of Practice BS 8301 ‘Building Drainage’ and BS 8005 ‘Sewerage’. (5 minute test 100mm on U tube to drop no more than 25mm). However current practice in many other European Countries confirms the research by CPA that the introduction of a higher pressure test to 1000mm rather than the current 100mm would overcome most of the shortcomings in BS test. These may be summarised as follows:1. The BS air test specifies a constant requirement regardless of diameter and length of the pipeline. 2. The air test is relatively more severe on smaller pipe diameters. 3. Pipe wall dampness affects air test results, particularly on smaller diameter pipes and at the low pressure specified. The following air test procedure is consistent with that described in BS 8301 and the Water Authorities Association publication “Sewers for Adoption”. 1. Seal the ends of the pipeline by means of expanding or inflatable drain stoppers. 2. Connect a ‘U’ gauge (manometer) to the test nipple of the drain stopper by means of rubber tubing. 3. Raise the internal pressure of the system until the ‘U’ gauge indicates slightly more than 100mm. Purpose made drain testing equipment is so calibrated that the scale indicates the actual pressure in mm water gauge. (See figure below) 4. Allow about 5 minutes for stabilisation of the air temperature (a 1º change in temperature is reflected in a change in pressure of about 38mm on the gauge). 5. Adjust the pressure to 100mm by either introducing further air or by bleeding off any excess pressure. 6. Observe the fall in indicated pressure over a 5 minute test period. The residual pressure should be not less than 75mm.

To test the pipeline, fit strutted plugs at each end and pump air until a pressure of 1m head is shown on the U tube. Allow the pressure to drop recording the time for the head to fall from 900mm to 800mm. This time should not be less than that shown in the table above for the appropriate nominal pipe size. These modifications to the BS test incorporating these higher pressures are illustrated above.

Spigot & Socket Pipes
Jointing & Laying
Jointing Procedure Forsheda 140 Lamell Sliding Rubber seal permits installation with very little force as there is lubricant enclosed within the seals sliding layer, thus there is no friction between concrete pipe and rubberseal. The sliding layer, when in final position locates itself in the gap between spigot and socket and then prevents concrete to concrete contact if pipe is deflected. Installation • Fit the seal onto spigot as shown on Fig.1. • Centre the spigot in the socket as Fig. 1. • Slide the pipes together and the lubricated flap will move over top of the compressed rubber seal as Fig. 2 and finish as shown on Fig. 3. rings are compatible with the pipes to be laid, then the following procedure should be followed: Clean the Pipe Ends Brush or wipe with rag to remove adhering part or water. Ice may be removed with methylated or a gas torch. Take care not to damage the concrete. Inspect Joint Surfaces Inspect the joint faces for damage which may affect the performance of the joint. Handle Pipes with Care Use only proper lifting equipment, eg woven slings. Make sure the pipe is balanced so that it is horizontal. Fit the Ring Fit the correct ring in the correct position and equalise the tension by lifting out intervals at its length and letting it snap back against the socket (see Joint details) Clean the Socket End Brush and wipe the end of the pipe fitted previously to remove any particles or water, ensure that the receiving socket is clean and undamaged.

The relevant pipe diameter is stamped on each rubber ring. Rubber rings should be carefully stored and protected from sunlight, oils, greases and heat, if rings have been tied they should be separated a few days before using in order to eliminate minor impressions the tying may have caused. Joint rings are normally Styrene Butadiene Rubber (SBR) complying with EN 681-1. Nitrile and Ethylene Propylene Rubber (EPDM) can be supplied if specifically ordered to meet special conditions, but are not normally available from stock.

Make the Joint The jointing procedure should develop a steady controlled push or pull until joint is in final position. Method of jointing will depend on size of pipe. Ensure timber blocks are used to prevent damage to socket of pipe.
Ref: TC11/6

Mechanical plant should not be used to push pipes down to their correct level. When jointing pipes the last pipe laid sometimes has a tendency to reassert therefore it should be proped and checked before laying commences.

Recommended Trench width and Bedding pipes
When laying pipes, to attain its full potential as a load bearing structure, trench width, proper bedding and backfilling are equally as important as the actual pipe strength. In fact, almost 50% of the completed structure is attributed to proper design and good workmanship. Any increase in trench width above that Recommended Maximum specified will increase Trench Widths the load on the pipe measured at crown of and a narrower trench may impede the pipe = Bd proper placing and Pipe Trench consolidation of bedding.

It is recommended that were pipes have to be airtested, it should be done every fourth pipe and prior to back filling. Cover to pipes (H) laid in fields for agricultural purposes only = 600mm. However, it is advisable that pipes laid under roads carrying traffic or grass verges adjacent to such roads, should have a minimum 1200mm cover. Never drive across a pipeline with minimum cover unless at prepared crossings. Ground water should be kept below the bottom of trench by use of temporary drains and not allowed to rise before backfilling is complete. Special care should be taken with the bedding material immediately surrounding the pipes to minimise the possibility of lumps or others coming into direct contact with pipes thus causing point loading. Never bulldose backfill directly into trench.

The selections of bedding material and bedding class is influenced by many factors which include the nature of the ground, the loads acting on pipeline, availability of a particular type of bedding material. The ideal is crushed rock or gravel that is compatible and provides stable embedment. For more details on bedding and pipe specifications see C.P.S.A. (Concrete Pipe Systems Association) publications.

The pipe line contractor should provide suitable equipment for offloading, stacking and stringing out pipes and other accessories on site. Offloading should take place at the nearest hard road to the point of installation provided it is accessible for delivery trucks. All units must be left in a stable condition well clear of the edge of trench. Pipes should be handled horizontally using a properly designed ‘c’ hook or other purpose designed equipment, but not unprotected chains. For safety reasons always know the weight of pipe to be lifted.

Never Lift pipes or accessories as shown in Fig. 3 which is likely to cause damage to spigot or socket. Where stacking is necessary, this must be on level ground and the bottom layer of pipes securely chocked to prevent pipes from rolling or stack from collapsing. Pipes should be supported under the barrell of the pipe so that the sockets are free from load, they should preferably be stacked barrell to barrell with sockets overhanging alternative sides.

...commissioned in 1929 in the Philippines. It is part of the Angat-Ipo-La Mesa water system, which supplies most of the water supply of Metro Manila. The La Mesa Dam is an earth dam whose reservoir can hold up to 50.5 million cubic meters and occupying an area of 27 square kilometers. The water collected in the reservoir is treated on-site by the Maynilad Water Services, and at the Balara Treatment Plant further south by the Manila Water. Both water companies are private concessionaires awarded by the Metropolitan Waterworks and Sewerage System, the government agency in charge of water supply. It is a vital link to the water requirements of 12 million residents of Metro Manila considering that 1.5 million liters of water pass through this reservoir every day. It is also the last forest of its size in the metropolis. La Mesa Watershed in Quezon City is the primary source of drinking water of about 12 million Metro Manila residents. The property is owned by the Metropolitan Waterworks and Sewerage System (MWSS), a government agency. La Mesa Watershed is 2700 hectares, 700 hectares of which is the reservoir and 2000 hectares of which is the surrounding forest. This forest is the last remaining one of its size in Metro Manila and serves as its carbon dioxide sink. La Mesa Watershed, therefore, is vital to the city, not only because it is a primary source of drinking water, but also because its forest functions as the lungs of Metro Manila, providing it with clean air.

Chase Manhattan Bank

...History A former American holding company, Chase Manhattan Corporation’s roots were planted during the final days of the 18th century in New York. During this time, after an epidemic of yellow fever the New York state legislature chartered the Manhattan Company to build a water supply system to bring clean water to the state. Because of the surplus of capital, some $2 million, the directors voted to use those funds to open an office of “discount and deposit”. On September 1, 1799, the Bank of the Manhattan Company was founded by Aaron Burr and opened in a house on 40 Wall Street. Over the next few years, after the success of its waterworks, the company sold the waterworks and retained its focus solely on banking. Growth was steady over the years, but its expansion took off after the onset of the 20th century. In 1918, the company acquired its first branch office after a merger with the Bank of the Metropolis. Two years later, it merged with the Merchants’ National Bank of the City of New York and then the International Acceptance Bank, Inc in 1929. This merger noted the banks future in foreign trade financing. The Chase National Bank was organized September 12, 1877, by John Thompson, who named the bank in honour of the late U.S. Treasury secretary Salmon P. Chase although Chase had no connection with the bank. Chase National’s growth was phenomenal, and by 1921 it had become the second largest national bank in the United States, without any mergers. After that year the bank...

Mr. Johnson

...PROJECT COST MANAGEMENT Juan Gonzales, a systems analyst and network specialist for a waterworks department in a Mexican city, had always aspired to be a project manager to expand his knowledge. A friend of Juan’s invited him to attend a project review meeting that included a project that Juan was interested in. This project was for the Surveyor Pro information system which would assist government surveyors to do their job more effectively by providing additional tools. While Juan was in attendance, he quickly learned that the meeting focused on budget related conversations rather than the actual project. The primary issue with this case is that Juan doesn’t have any background in cost management. Juan sees how important the government officials are reviewing other projects cost management and he should understand how cost management plays into being a project manager. This could also add a new facet to Juan’s career. And while time and resource issues are always noteworthy, the factor that often has the biggest influence on project success or disaster is whether or not the project team can – or cannot – enhance project outputs with effective cost management. The government officials are concerned with cost management because IT projects have a poor track record for meeting goals. According to a 1995 report from The Standish Group, we spend more $250 billion each year on IT projects in the United States. The average cost ranges from $2 million for a large...

Law of Tort

...Introduction This assignment will establish the elements needed for a person to be held liable in Tortious Law. Once the elements have been established they shall then be used to determine if the individuals in each scenario would be held liable. Tort Law Tort Law in layman’s terms is a civil wrong. It does not necessarily need to be an illegal action but an action that has consequently caused harm or suffering to another. The main outcome for a person claiming they have been a victim of a tortious act is compensation. For a successful tort claim the three main elements need to be present and their needs to be a standard of proof; a balance of probabilities. The Necessary Elements As followed in Donoghue v Stevenson [1932] AC 562 i. Duty of Care ii. Breach of Duty iii. Damage caused by Breach of Duty. Causation This coincides with the three part test established in case that leads precedent in tortious liability, Caparo Industries Plc v Dickman [1990] 1 All ER 568. i. Foreseeability of Damage ii. A relationship characterised by the law as one of proximity or neighbourhood. iii. A relationship characterised by the law as one of proximity or neighbourhood Duty of Care Duty of care prior to 1932 was restricted to situations where a relationship had already been established such as a doctor-patient relationship. However in Donoghue v Stevenson that duty of care became adapted. Lord Atkin formulated a principle known as the ‘neighbour test’; ‘take reasonable care...

Chicago Fire

The conflagration burned from Sunday, October 8, to early Tuesday, October 10, 1871. It killed hundreds and rampaged just over 3 miles while devastating the entire city. Though the fire was one of the largest of the 19th century, the rebuilding that began soon after made them one of the most popular cities of America. The starting of the fire initially had everyone fooled. that a cow in a barn had kicked over a lantern, and things went a blaze.Though the barn owned by the O’Leary was the first to be taken over by the fire, the reporter came clean to exaggerating the story for sales. The barn was the start but the wood structures within Chicago, combined with a drought was no match for this fire. The wind carried ember from the fire toward the city.These factors didn’t even shake the residents of the Windy City. As the fire continued to grow firefighters responded, and were soon exhausted. The first alarm was received around 9:40 by the department when a fire alarm was pulled at a local pharmacy. This was when the fire was relatively small but when it got larger the guard took the corrective actions to send more people but it he sent them in the wrong direction. It was when the fire overcame a tall church, the flames crossed the river. Ships that lined the river, the city's wood-plank sidewalks...

Alternative Energy Development in Japan

...Alternative Energy Development in Japan Japan is a densely populated country, and that makes the Japanese market more difficult compared with other markets. If we utilize the possibilities of near-shore installations or even offshore installations in the future, that will give us the possibility of continued use of wind energy. If we go offshore, it's more expensive because the construction of foundations is expensive. But often the wind is stronger offshore, and that can offset the higher costs. We're getting more and more competitive with our equipment. The price—if you measure it per kilowatt-hour produced—is going lower, due to the fact that turbines are getting more efficient. So we're creating increased interest in wind energy. If you compare it to other renewable energy sources, wind is by far the most competitive today. If we're able to utilize sites close to the sea or at sea with good wind machines, then the price per kilowatt-hour is competitive against other sources of energy, go the words of Svend Sigaard, who happens to be president and CEO of the world's largest wind turbine maker, Vestas wind systems out of Denmark. Vestas is heavily involved in investments of capital into helping Japan expand its wind turbine power generating capacity.
