Our engineering solutions address the full lifecycle of treatment infrastructure, ensuring reliable system performance, regulatory compliance, and long-term environmental sustainability.
Our engineering services include:
CETEC delivers sustainable, energy-efficient treatment systems designed for long-term operational performance, environmental protection, and compliance with national and international standards.
We implement practical, community-focused technologies tailored to Sri Lanka’s environmental needs, improving water, waste, and resource management sustainably.
CETEC specializes in appropriate and context-driven environmental technologies that are cost-effective, easy to operate, and suitable for local conditions. Our solutions support rural communities, local authorities, industries, and development projects seeking sustainable outcomes.
This includes decentralized water and wastewater systems, low-energy treatment solutions, stormwater management, rainwater harvesting, and solid waste reduction approaches. We focus on technologies that balance environmental performance, affordability, and long-term operational viability.
Through careful assessment and stakeholder engagement, we ensure that implemented technologies deliver real-world benefits while supporting national sustainability and development goals.
We provide comprehensive air quality monitoring, noise assessment, and emission control solutions to support environmental compliance and protect community and workplace health.
CETEC conducts industrial, ambient, indoor, and stack air quality monitoring in accordance with CEA regulations and internationally recognized standards. Our monitoring programs identify key pollutants such as PM2.5, PM10, TSP, SOx, NOx, O₃, and VOCs, enabling clients to understand pollution sources, evaluate environmental impacts, and implement effective control strategies.
In addition to air quality monitoring, CETEC provides environmental noise measurement and noise mapping services for industrial facilities, construction projects, infrastructure developments, and urban environments. Using calibrated precision instruments and internationally accepted methodologies, we assess ambient noise levels, occupational noise exposure, and community noise impacts. Our noise mapping and modeling services help identify noise hotspots and guide mitigation strategies for regulatory compliance and community protection.
We also design and support air pollution mitigation and emission control systems, including scrubbers, filtration units, and particulate control solutions tailored to industrial operations. For commercial and occupational environments, we develop indoor air quality improvement strategies to enhance health, comfort, and productivity.
Through integrated air quality monitoring, noise assessment, and emission control engineering, CETEC helps organizations maintain regulatory compliance, protect employees and surrounding communities, and contribute to healthier environmental conditions across Sri Lanka.
We conduct thorough EIA and IEE studies to assess project impacts and ensure full compliance with Sri Lankan environmental regulations.
CETEC is a Central Environmental Authority (CEA) registered consultant for Environmental Impact Assessments (EIA) and Initial Environmental Examinations (IEE). Our multidisciplinary team manages the complete assessment process from screening to final approval.
Our EIA/IEE services include baseline environmental studies, policy and legal analysis, impact identification, mitigation planning, stakeholder consultation, and detailed reporting in accordance with CEA guidelines.
By providing accurate assessments and practical mitigation measures, we help projects proceed responsibly while minimizing environmental and social risks.
We guide businesses through environmental compliance, documentation, and regulatory requirements to ensure responsible and certified operations.
CETEC supports organizations in meeting CEA regulations, EPL requirements, monitoring obligations, and reporting standards across multiple environmental sectors. Our services include compliance audits, regulatory documentation preparation, authority coordination, and ongoing advisory support.
We assist clients with environmental monitoring plans, compliance reporting, permit renewals, and corrective action strategies, reducing the risk of penalties and operational disruptions.
With strong regulatory knowledge and technical expertise, CETEC acts as a trusted partner for long-term environmental compliance in Sri Lanka.
CETEC conducts capacity building programs and technical training workshops to strengthen environmental management, operational skills, and regulatory compliance across industries, institutions, and communities. Our programs combine technical expertise with practical, field-based learning, delivered by experienced engineers, scientists, and laboratory specialists.
Training programs and technical workshops include:
We design and implement efficient water treatment systems that deliver safe, clean, and reliable water while meeting Sri Lankan quality standards and regulatory requirements.
Our expertise covers surface water, groundwater, raw water, and treated drinking water systems, serving rural water supply schemes, industrial facilities, and municipal projects. CETEC provides end-to-end solutions including planning, system design, technology selection, installation, commissioning, and operational support.
We specialize in advanced treatment technologies such as biological treatment systems, membrane filtration, chemical dosing, filtration, and disinfection processes, ensuring compliance with CEA guidelines and national drinking water standards. Existing treatment systems are assessed and optimized to improve performance, efficiency, and lifecycle cost.
In addition, we support water reuse and conservation strategies, rainwater harvesting systems, and sustainable water management solutions that reduce environmental impact while ensuring long-term reliability.
We provide wastewater and industrial effluent treatment solutions that help organizations meet discharge regulations and protect surrounding environments.
Our services cover domestic sewage treatment, industrial wastewater treatment, and effluent management systems for industries including manufacturing, food and beverage, processing plants, and commercial facilities. We design, upgrade, and troubleshoot wastewater treatment plants (WWTPs) to ensure compliance with Environmental Protection License (EPL) requirements.
Our technical expertise includes biological treatment, chemical precipitation, sludge handling, tertiary treatment, and reuse-oriented system design. We also conduct performance evaluations of existing treatment units and recommend optimum chemical dosing and process improvements.
By focusing on efficiency, compliance, and sustainability, CETEC helps clients minimize environmental risks while maintaining reliable wastewater treatment operations across Sri Lanka.
