Past projects include being the main drilling contractor for Sime Darby Water Resources Sdn Bhd to drill, construct and development of multiple wells for ‘Groundwater Resources Study at Batang Padang District Perak’ - an inter-state commercial water supply project. This exploration calls for the drilling in hard rock formation of 320-255 mm diameter bore to a depth of 300 meters deep. The project aims to develop sustainable groundwater resources with an ultimate capacity of 2,000 MLD (million litres per day). This was a crucial springboard for the company as it was DRILCO’S first major project of this magnitude.
Apart from drilling services, DRILCO was appointed by Megasteel Malaysia, one of the leading company producing hot rolled coils and special alloy steel to evaluate the impact on groundwater regime in and around the environment of Brookland Industrial Estate (Olak Lempit) in the Sungai Langat basin for groundwater abstraction from the current 3.5 MGD to 10 MGD. This EIA study involves the collection of geological and hydrogeological data; evaluate the impact of the current groundwater abstraction; conduct groundwater flow modeling analysis, the modeling analysis amongst others is to model saltwater ingression if any, towards the sensitive areas in the region and finally, to review and model ground subsidence. Up to date, DRILCO has completed two large diameter alluvium well in Megasteel factory producing 500 m³/hr (12.0 mld) and 400 m³/hr (9.6 mld) respectively.
DRILCO is proud to be associated with Worldwide Landfills Sdn Bhd, a leading company with state-of-the-art waste management services, as their pioneer contractor to carry out the design, drilling and construction of Sanitary Landfill Gas Extraction Well System, believe to be the first of its kind in Malaysia. The main objective of these gas wells are to gather reports on typical composition of landfill gas, control pollution by reducing greenhouse gas emission that causes global warming and wherever possible, if the quantity and quality justify, transform as sources of fuel for green energy utilization and power generation.
Other notable experiences include the study of Groundwater Hydrogeological Regime for Petronas RAPID project at Pengerang, Johor who calls for multiple well drilling and Rural Water Supply scheme at Orang Asli settlements in Malaysia for Ministry of Rural and Regional Development.
The company’s additional significant drilling achievements feature multiple projects for LRAs (Loji Rawatan Air) in Northern Kelantan for AKSB, JSANK, PAAB and Project Consultants using Flooded Reverse Circulation (FRCD) drilling methodology. Water supply project sites that DRILCO participated directly and indirectly through third parties include LRA Kelar (Phase 2 Exploration), LRA Perol, LRA Kg. Puteh, LRA Chicha, LRA Jelawat, Medan Telaga Kg. Pasir Tumboh, Kg. Laut, Kg. Pengkalan Kubor, Pasir Mas and Pechong, Tanah Merah.
