SYNOPSIS

In a building there are many services, among them the LEAST glamorous is the SANITRY 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 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. To mask the smell it is common to see odorizer inside the toilet, a chemical compound which is carcinogenic now is a norm and acceptable. It adds cost to the maintenance of the toilets. The concept of Indoor Air Quality goes out of the window. An odorless toilet is possible if the concept of water seal is 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) concept has been promoted 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. The RWH concept can be done with a VERY SIMPLIFIED gravity feed concept that has minimum fittings and does not required the expensive “special” fittings. This is probably why the implementation of RWH did not take off even after all these years. It is possible to design and installed RWH system with minimum costs yet has the ability to have treated water as backup during the dry season AUTOMATICALLY and easily maintainable.
