Literature Review

Geology & Hydro-Geology

• Geology Map

Literature Review


• Vertical Profile

Literature Review


• Hydro geology– Site is a marshy land– Water table is almost at surface level

(0.1-0.5m)– Site is by the side of Bolgoda lake which

increases vulnerability of ground and surface water pollution

– Polluted water wells are good indications

Preliminary Site VisitKaradiyana Waste Dump

Site Personnel Interviews

• Site Manager – Mr. Kosala Gunawardena– Site was acquired by WMA in 2009– Until 2010 there was no any proper road– Gov. funded Rs.100Mn to on access roads

in 2010– Waste types: MSW, C&D, BW , NTIW– Waste is managed in cell vise operation

Site Visit

Cell vise Operation

• A Cell in a block of 150m*150m• There are 4 cell being operated• Layer of waste 6” thick is made• Second layer on top of old one will be

made within 36 Hours• Densities

– Receiving material : 450kg/m3– Compacted : 750kg/m3– Within one week : 850-900kg/m3

Site Visit


• Site Manager – Future Plans

• A power plant is to be constructed in next year with the cost of US$ 3Mn

• Compost plant will be installed next year• No proper solution for leachate

Site Visit


• Workers– Around 30 workers– Hand sorting– Working 8am to 5.30pm– Separate 100kg a day by a person– Separation is < 0.6% !

Site Visit


• Workers– Waste separation

• Workers– Waste Collection

Site Visit


• Workers– Price (per kg)

• Plastic Rs.35/=• PET Rs.45/=• Tin Rs.35/=• Coconut shells Rs.8.50/=• Glass Rs.4.50/=

ConclusionPhase-1

Karadiyana Waste Dump

Guide to Phase (ii)

• Phase (i) provides the basis for phase (ii) (exploratory site investigation).

• We should look for the vertical profile of waste, using augur driling.

• Water samples along the canal and Bolgoda lake (Upstream and downstream) and from surrounding wells.

• Assessment of leachate is necessary.
