SYNOPSIS

Often the back lane of landed residential houses where the main sewerage pipe and manholes are located can be fenced off for security reason hence it is not accessible for maintenance and repair of leaking underground pipes. This can  impact the sanitary system and creates a health issue emitting foul smell to the surrounding areas.

There are local authority guidelines and SPAN Technical Sewerage Systems that stipulate the width of the back lane and yet the width has been reduced in new residential housing development.

In this respect in new townships this issue has been resolved with the relocation of the main sewerage line to the FRONT of the houses. This change now requires Engineers to review their design of the internal sanitary pipes to consider the routing, gradient and distance from backend to discharge at the front of the house where the main sewerage will be located.

The main concern would be to remove blockages of the internal sanitary pipes which are buried underground. There is a need to review existing design on the location of Inspection Chamber and cleaning eyes strategically installed to carry out rodding to clear the blockages. Top access floor trap can be transformed into an EFFECTIVE CLEANING EYE when the water seal is removed from the it.

The 2 distinguished speakers will provide both conceptual and PRACTICAL solutions obtained from their hands-on experience to meet the new requirements of the current design.

As all internal sanitary plans are submitted to the authority for records only the liability still under the PEPC submitting person.
