Types of water closet pdf

WATER CLOSET 8With respect to shape, water closets can be classified into two types: 1. The Round Type is intended for installation on a limited space. 2. The Elongated Type is more comfortable but occupies a larger space. This type has a large amount of standing water inside the bowl that is more sanitary and easier to maintain. Water closets A WC is a plumbing fixture primarily intended for the disposal of human waste by using water to flush it through a drainpipe to the main sewer stack. Types : Squat toilets :The most common toilet in used in our nation is the Squat toilets, in which water carries the waste into sewers. Flush toilets: The most common design in A Guide to Better Public Toilet Design and Maintenance Fourth Edition 2018 6 well as down lights above the wash basin/mirror (Refer to Illustration 8 for examples). According to the NEA's COPEH, the minimum lighting level shall be 300 lux to ensure that areas with water closets, wash basins and urinals are sufficiently illuminated. A STUDY ON EVACUATION PERFORMANCE OF SIT TYPE WATER CLOSET BY COMPUTATIONAL FLUID DYNAMICS(CFD) Mohd Reza Fadhlan Bin Daud1, Suhana Binti Ramli2 1,2 Mukah Polytechnics rezafadhlan@pmu.edu.my, suhanaramli@pmu.edu.my ABSTRACT This study was undertaken to study the performance of the type of toilet seat by using CFD numerical methods to obtain the optimum flow rate to reduce water usage. inch of water column (249 Pa). 12 inches of water column equals 0.433 psig. 1 inch of water column equals 0.036 psig. This also refers to half of the trap seal which shall be at least two inches. Trap seal With an atmospheric pressure of approximately 14.7 psi at sea level, there can be no more than plus or minus 0.036 psig difference present Irrigation: In some cases, water from piped network is used for irrigation of green houses, orchard or garden. Then it will depends on the area, type of crops and weather, might vary a lot across the year. The pattern is usually quite flat as the water is done constantly for few hours. 1.3. Average daily usage There must be a clear floor space of 42 inches (1066 mm) minimum from the centerline of the water closet to the nearest obstruction/wall. A lavatory may not overlap this clear space. Grab bars are provided on the side and back wall (see figure here-under). 4.16.3* Height. The height of water closets shall be 17 in to 19 in (430 mm to 485 mm Some of the most common types are as follows. 40 PLUBERGENERL L Types of fittings 1. Collar 2. Elbow 3. Gasket 4. Union 5. Reducer 6. Tee 7. Nipple 8. Trap For a building, the plumbing system should be designed in a way that water is distributed uniformly, throughout the day. Water supply from city main is irregular and we have to rely on two well pumps for water domestic use which have a capacity of 5m3/hr each. However drinking water is supplied from city main water supply. The city water pressure is insufficient. (a) Work out daily water requirement, underground and overhead tank capacity A public water closet has a WSFU value of 5.0. Even though the water closet (tank) is the same as the private water closet and uses the same amount of water, a public water closet has a higher WSFU value. The public water closet has a higher usage frequency, which increases the WSFU value. theoretical water demand considerably exceeds actual consumptive water use. 1.1.2 Types of catchment surfaces A catchment surface is the part of a RWH system that receives rainfall and drains
