SYNOPSIS   

In a building there are many services, among them the LEAST glamorous is the SANITARY system. This is expected because the sanitary system channels all the soil and waste out of the building to the external manhole, an effective method to ensure foul smell does not enter the building. Also the contract value is probably the lowest too because it relies on the gradient and gravity force to move the soil and waste inside the plastic pipes. Now a probable FACT Architects, Engineers and Interior Designers would focus on the LAYOUT ONLY and most likely leaving the detailing and design aspects to the Plumbing Contractor. This dependency could be the likely reason why our toilets often faced blockages within a short duration AND are smelly. How many would agree with this claim? To mask the smell it is common to see odorizer inside the toilet, a chemical compound which is carcinogenic. High profile buildings like airport every toilet has a full-time staff station to carry out on the spot cleaning. Is an odorless toilet possible OR maybe a smelly toilet already a norm? Designer must understand the concept of water seal to be applied to ALL fittings and branch discharge pipes properly routed at the right gradient. Elbow must not be used without a drop of elevation!!!

Rainwater Harvesting (RWH) is already mandated in the UBBL to conserve treated water and it will CERTAINLY be possible if the collected rainwater is used for WC flushing, each flush saves 6 liters of treated water. It is unlikely to find UNTREATED rainwater being used to flush WC instead merely for landscape only. If a survey to be conducted since the UBBL on this, there will be surprises, many are no longer in operations. The RWH concept can be done with a VERY SIMPLIFIED gravity feed concept that has minimum fittings and does not require the expensive “special” fittings and yet has the ability to use treated water as backup during the dry season AUTOMATICALLY and easily maintainable
