What thickness of soil cover is required at the end of each day?

A compacted layer of soil, 15 cm thick, should be placed over the waste at the end of each working day (Clause 8.1.3).

What is the recommended minimum distance of a landfill from a water source?

The site should be as far as possible from any water supply source, generally not less than 500 metres (Clause 4.2.1).

What are the primary construction methods described in the code?

The code describes the 'Area Method' for flat ground and the 'Trench Method' where the water table is not near the surface (Clause 6).

What is the minimum thickness for the final cover after the landfill is full?

A minimum final cover of 60 cm of compacted soil is recommended (Clause 8.2).

Practical Notes

This 1983 guide is significantly outdated and its provisions are considered minimal by modern environmental standards.

Current landfill design in India is legally governed by the Solid Waste Management (SWM) Rules, 2016, which are mandatory and much more stringent than this code.

This document is now primarily of historical and academic interest, useful for understanding basic landfilling concepts but must not be used for actual design without referring to current SWM rules.
