Effective Treatment for Safe Discharge and Environmental Protection
Orient Water Services provides comprehensive sewage treatment solutions for residential, commercial, and industrial applications across Pakistan. Our integrated approach combines biological, chemical, and physical treatment processes with specialized chemicals from Veolia’s HYDREX™ range and precision dosing equipment to ensure effective treatment, regulatory compliance, and environmental protection.
Understanding Sewage Treatment
Sewage treatment is the process of removing contaminants, organic matter, pathogens, and nutrients from wastewater before discharge to the environment or reuse. Proper sewage treatment is essential for:
- Public Health Protection – Preventing waterborne disease transmission
- Environmental Compliance – Meeting NEQS discharge standards
- Water Resource Protection – Preventing pollution of rivers and groundwater
- Odor Control – Maintaining pleasant surroundings
- Community Relations – Demonstrating environmental responsibility
