E. SEWAGE DISPOSAL SYSTEM, REFUSE AND HANDLING

1. SEPTIC TANK. A receptacle or water-tight vault is used to collect organic waste discharge from the house sewer and designed and constructed so as to separate solids from the liquid, digest the organic matter through a period of detention, and allow the effluent to discharge into a storm drain.
2. CATCH BASIN. A receptacle in which liquids are retained for a sufficient period of time to deposit ‘settleable’ materials.
3. PUBLIC SEWER MAIN. A public sanitary waste disposal system consists of a treatment unit that conveys the raw waste to the disposal system.
4. A common way of disposing of solids is by INCINERATION. This is a controlled burning of combustible waste. This can be an effective waste reduction method for 70 percent of all municipal waste. If this is operated properly, it can reduce bulk by 90 to 95 percent. Ash left over is generally disposed off in a landfill.
5. Another method of disposing of municipal solid wastes is by dumping refuse at a pre-planned site, compacted and covered with a layer of earth. This method is called a
   SANITARY LANDFILL.
6. When garbage from different floors of a high-rise building is disposed off from an opening and is directly led to the basement garbage bin. This is called the RUBBISH CHUTES.
7. GARBAGE DISPOSER. This is a contraption inverted to dispose of leftovers straight from the kitchen sink. Simply turn on the faucet, flick the power switch and place the leftovers such as bones, fruit pits, rotten vegetables, spoiled bones and washed down the drain pipes.
8. After the ground preparation, a LINER should be laid out on the area enclosed for the sanitary landfill. The main purpose is to prevent the seepage of leachate (dirty water, to cause liquid to percolate) deep down to the groundwater strata. This consists of soil or composite material such as synthetic plastic or asphalt sheets.
9. TRENCH METHOD. A method of landfill wherein a tractor digs a trench with a bulldozer blade and trucks dump the refuse to it. Then the tractor compacts the refuse thoroughly and covers it with the earth that was dug up earlier. This method is primarily used on ground level.
10. AREA METHOD. This method of landfill is generally
    used on rolling terrain where the existing slope of the land can be used as a basin. In this method, trucks deposit refuse over the selected area. Huge, heavy tractors with special compacting wheels press down the refuse. Then the refuse is covered with earth hauled in from elsewhere.
11. Collection of human wastes is done by elaborate systems to carry most liquid sewage to WATER TREATMENT PLANTS, where the sewage undergoes a series of treatment steps to remove polluting materials and biological and chemical contaminants that can harm human health or ecological systems. The first stage is the trapping or screening of coarse suspended matter into a grit chamber. Then the use of aerobic microorganisms to break down the organic matter left in the sewage is called biological oxidation. Then the third phase, chemical treatments are used to remove undesirable constituents that remain. What results is drinking quality water.
12. BIDET. A fixture that appears like a water closet, since
    a person sits down on it. But it is designed as a combination lavatory that can plug the drain and collect hot & cold water, with an inverted water sprayer to clear the most delicate and well-guarded parts of the body.

F. MISCELLANEOUS QUESTIONS

1. What determines the size of a leaching field? PERCOLATION TEST
2. What is an important concern in the private water supply?
   HARDNESS
3. What part of the water supply design is affected by building height? STATIC HEAD
4. Statements:
   • Correct
     • Dry pipe sprinkler systems are more efficient than wet pipe systems.
     • The hazard classification does not necessarily affect sprinkler layout.
5. The pressure in a city water main is (0.39273 MPa). If the pressure loss through piping, fittings, and the water meter has been calculated as 231 psi (o.15847 MPa) and the highest fixture requires 12 psi (0.08268 MPa) to operate, what is the maximum height the fixture can be above the water main? 50 FEET (15M)
6. You have been retained by a client to design a house in a
   suburban location. The nearest water main is one block
   away (about 1000M) and the city has no plans to extend the line in the near future. City and county regulations do permit the drilling of wells. What should you recommend your client regarding water supply? ESTIMATE THE COST OF EXTENDING THE MUNICIPAL LINE, SINCE THE WATER QUALITY IS KNOWN AND IT WOULD ENSURE A LONG-TERM SUPPLY. CONSULT WITH NEARBY PROPERTY OWNERS WHO PLAN TO BUILD IN THE AREA TO SEE IF THEY WOULD BE WILLING TO SHARE THE COST OF EXTENDING THE LINE.
7. Which statements about drainage are correct?
   • Correct:
     • Vents help prevent the drainage of water from traps.
     • The house drain cannot also be called the building sewer.

9. One component of a plumbing system that every building has is a: STACK VENT
10. Select the incorrect statements:
    • Correct:
      • Several types of plastic can be used for cold water piping, but only PVDC is used for hot water supply where allowed by local codes.
      • Steel pipe is more labor intensive and requires more space than copper pipes in plumbing chases.
      • ABS is suitable for water supply.

The post National Plumbing Code of the Philippines: Basic Principles (2022) appeared first on CONSTRUIRE.

The birth of the plumbing practice in the Philippines is traced back to the 17th century. The WALLED CITY known as Intramuros was established by the Spaniards as a model community. The Friar Engineers who built the government buildings, residential and other structures, incorporated European standards in their plumbing installations.

During the 18th and 19th centuries, the Filipino plumbers were assigned the task of maintaining, repairing and/or remodeling plumbing systems in all “pueblos” or towns including churches, convents and government buildings.

The recognized plumbers then were called upon by the “ilustrados” or the elite group to act as consultants of the plumber journeymen on matters pertaining to plumbing installations in villas and mansions.

PLUMBING took a great leap at the turn of the 20th century with the arrival of the American soldiers, engineers, Thomasite teachers, doctors and evangelists. Health and hygiene became priority when epidemics including cholera, leprosy, schistosomiasis and other contagious diseases engulfed the Philippines. Alarmed, Governor General Harrison issued a letter of instruction on proper waste disposal in all municipalities.

Sometime in 1902, the PLUMBING TRADE was duly recognized by the government. The City of Manila was the model community. Master Plumber John F. Hass became the first Chief of the Division of Plumbing Construction and Inspection.

Through the initiative of the Filipino Master Plumbers, a plumbing code based on the Plumbing Code of the United States was incorporated into the Building Code for the City of Manila.

In 1935, Francisco Geronimo, Mariano de Ocampo, Igmidio Suarez, Eusebio Mina, Jose Revera, Raymundo Reyes Sr., Reberto Feliciano, Gregorio Lazaro, Raymundo Gumapac, John Jones, Trinitario Ortiz, Valentin Casupanan, Catalino Casupanan, Crispin Francisco, Teodoro Pastor, Cornelio Odvina and Jesus Tanghal Dera organized the National Master Plumbers Association of the Philippines (NAMPAP) and had it with the Securities and Exchange Commission.

Initiated by NAMPAP, the Department of Public Services of the City of Manila was created by an Act of Congress. City Ordinance 2411, otherwise known as ” The Plumbing Code for the City of Manila” Was Enacted in consultation with NAMPAP. The practice of plumbing was eventually placed under the Department of Public Services, Manila.

The National Government, through the Bureau of Public Works, and other cities and municipalities adopted the Plumbing Code of Manila. NAMPAP spearheaded the enactment of a law regulating the practice of master plumbing in the Philippines.

In 1954, the Third Congress of the Republic of the Philippines in its Second Session, approved after the third reading House Bill No. 962. This became Republic Act No. 1378. On June 18, 1955, R.A. 1378, otherwise known as the “PLUMBING LAW OF THE PHILIPPINES” was signed by President Ramon Magsaysay.

On January 28, 1959, the National Plumbing Code of the Philippines prepared by the NAMPAP was promulgated and approved by Malacañang. NAMPAP also assisted in the passage of the law creating National Waterworks and Sewerage Authority (NAWASA).

In 1966-1969, the Board of Examiners for Master Plumbers and the NAMPAP prepared a Curriculum for Plumbing Engineering that was approved by the Department of Education and was first introduced at the Feati University.

On November 28, 1967, the First Amendment to the National Plumbing Code was approved, which affected the inclusion of “Asbestos-Cement Pipe” as an approved plumbing material.

Before Martial Law in 1972, Republic Act No. 6541 otherwise known as the “Building Code of the Philippines” was passed with the “National Plumbing Code of 1959” as referral code in full text.

In 1996, NAMPAP President JAIME M. CABASE spearheaded the updating of the Revised National Plumbing Code. Finally, in October 1999, NAMPAP submitted the Draft Code to the Board of Master Plumbers (BOMP) chaired by Engr. FORTUNATO H. AMOSCO. After careful review, the Professional Regulation Commission under Chairman HERMOGENES POBRE adopted the Revised Plumbing Code of 1999 which His Excellency, President JOSEPH EJERCITO ESTRADA approved last December 21, 1999 pursuant to Section 4 of R.A. 1378 known as the Plumbing Law.

In order to continuously upgrade the technical expertise of Master Plumbers and propagate the growth of the plumbing industry, NAMPAP have caused the holding of regular National Convention as well as Regional Conferences such as LUZON, VISAYAS and MINDANAO, as well as the Midyear Forum where manufacturers, dealers and suppliers of plumbing tools, equipment’s, materials and services are given the opportunity to conduct product presentations for the benefit of the plumbing practitioners.
