 Technical Definition:
“method of disposing solid wastes on land
without creating nuisances or hazards to public
health or the environment “

4. Project Overview
 In 1991, municipal solid waste dumping site was located in
Kampung Linosod - the upper part of a valley surrounded by
populated areas.
 Known to be non-engineered disposal site
 Leachate - produced from fluid of waste materials flow
directly down-valley and discharges to Sungai Pegalan.
 It affected the downstream water quality, led to complaints
made by villagers because of its foul odour and health
problems forcing it to close down soon after.

5. Project Objectives
 To provide proper and adequate waste disposal facility for
Keningau
 To meet future demand for waste disposal as it will grow in line
with the country’s development
 To minimize impacts towards the environment by developing
an environmentally friendly project with the introduction of
modern waste disposal methods
 To provide employment for locals

6. Project Location
Total land area = 30.5
hectares with 19.8 hectares
used for dumping operations
and the remaining as
conservation area.

7. Geological Data
Formation Crocker Formation in the northwestern Borneo
geosynclines
Sediments Massive grey sandstone, closely-bedded grey sand and
siltstone and grey, red, green and black mudstone and
shale
Age Eocene to Early Miocene
Mineralogy Fine but poorly sorted grains of quartz and composite
unidentified matrix which possibly is chert or argolite and
weathered plagioclase

8. Hydrogeology
• For monitoring – 4 river sampling locations are located within the
project boundary.

12. Conclusion
 Rivers are less polluted with the introduction of modern waste
disposal method
 Leachate collection treatment system will collect the leachate
dissolved from the waste and is treated before pumped out to
the river
 Several environmental impacts associated during pre until
post construction are considered in the proposal to ensure
high quality of environment is maintained and simultaneously
strengthen the country’s economy.
