No design requirements associated with maintaining safety functions are placed on the sanitary drainage system. 

Corrosion resistance Plastic piping materials are corrosion resistant and have low flow resistance. Plastic piping systems resist most normal household chemicals and many other substances that might enter a sanitary drainage system. The smooth wall of plastic pipe makes the transport of wastes and water more efficient and effective. Thermoplastic piping materials do not rust or corrode, and resist chemical attack from corrosive soils. 

An adequate drainage system should be provided for all locations where a large amount of hydrocarbon liquids has the possibility of release and may accumulate within the terms of the risk analysis frequency levels. Normal practice is to ensure adequate drainage capability exists at all pumps, tanks, vessels, columns, etc., supplemented by area surface runoff or general area catch basins. Sewer systems are normally gravity flow for either sanitary requirements or oily surface water disposal. Where insufficient elevation is available for the main header, lift stations are installed with a forced pressure outlet header to a disposal or treatment system. 

Wastewaters may be collected in separate drainage systems (for process, sanitary, and storm water) althongh industrial and stormwater systems may in some cases be combined. In addition, ballast water from bulk crude tankers may be pnmped to receiving facilities at the refinery site prior to removal of floating oil in an interceptor and treatment as for other wastewater streams. 

The presence of a trench/pipe system in Option B, used to remove rain accumulations, increases the risk that contaminated fire water might be inadvertently discharged into the sanitary sewer system. In order to reduce this risk, it is necessary to install a motorized valve in the drainage piping. This valve could be arranged to close automatically in the event of a fire through a signal from the fire alarm panel and manually as needed. It may also be desirable to use a valve which will automatically close in the event of loss of power. Alternatively, this valve could be normally closed and opened when needed. 

Sanitary Drainage. If complex systems of traps and check valves are to be avoided, the sanitary sewage and process wastes must run into a separate drain and sewer system. However, in municipalities this cannot be done and both types of sewage are mixed. Urinals, stools, washbasins.

Butyl rubber has very low water absorptivity and is highly resistant to bacteria, animal and vegetable matter, and the chemicals used to clean and clear sanitary drainage and disposal systems. The high-unsaturation grade provides fast, tight cures. The rubber, promoter, carbon black and oil in the compound shown in Table 10 need to be heat treated at 165 °C for at least 2 min, and the vulcanisate needs to be post-cured, for low compression set.

As more restrictions on product preservatives have been set in the last 10 years, more instances of microbial contamination have appeared and liquid detergent process equipment and operations have approached those used in the food and pharmaceutical industries. Process equipment is being installed to a more sanitary level, which means easier to clean and disinfect. Predominantly the equipment is designed for cleaning in place (CIP) without the need to disassemble. This chiefly means that surfaces are polished, circulation dead spaces are avoided, and drainage is virtually perfect. Usually the equipment is washed with alkaline and acid solutions, and then with a disinfectant solution. Additional equipment to handle and recirculate disinfectant solutions becomes part of the system design. 

Both the type and location of service urinals and stools for both men and women employees require prime consideration. It is important that the sanitary service be somewhat removed from the plant processing in order to simplify fittings underground. Process equipment service may interfere with sanitary service in drainage, since equipment drainage may overtax the system at periodic intervals. Therefore, each piece of equipment should drain directly into the main laterals. 

From 1866 to 1869, Worthen was the sanitary engineer to the New York Metropolitan Board of Health. In Brooklyn NY he reported upon an extensive addition to the sewer system. With Francis and Theodore G. Ellis (1829-1883), he served upon a committee to report on the failiu e of the Mill River Dam at Williamsburg MA, which had occurred in 1874. Aroimd 1890 Worthen was the chief engineer of the Chicago Main Drainage Canal. He was president of the American Society of Civil Engineers in 1887, and made honorary member ASCE in 1893.

Water, wastewater, and inundation protection systems are lifelines critically related to a communities resilience to earthquakes. Herein, water, wastewater, and inundation protection systems respectively refer to potable water, sanitary sewer, and storm water control and flood protection systems (includes urban drainage, river dam and levee systems, sea wall barriers, etc.). Water, wastewater, and inundation protection systems in modem urban settings are critical for public health and human survival, and their ability to...
