Kandy, a UNESCO World Heritage Site, is the second largest city in Sri Lanka. The city lies on the 'Kandy' plateau which is mountainous and thickly forested. With the development and population growth in Kandy, it is necessary to construct a wastewater treatment plant which include sludge drying beds. The sludge drying beds which occupy area of about 1.5 acres located in a hilly area on the outskirts of Kandy, namely Gohagoda. To provide the necessary flat platform areas and access road, 250 m length of reinforced soil slopes with slope angle of 65 degrees was constructed on site. The reinforced soil slopes comprise of single tier and two tiers slope with maximum height of 18 m, consisting of gabion facing units with layers of composite reinforcement geotextile. Total 44,000 m(2) of high tenacity composite reinforcement geotextile with characteristic ultimate tensile strength up to 100 kN/m were used in the project.
