Public Health Engineering

Public Health Engineering Services Across Pakistan

Clean water, effective sanitation, and reliable drainage are not just engineering challenges — they are fundamental human rights and public health imperatives. Arch-Tech Engineering Consultant Pvt Ltd has been delivering public health engineering solutions across Pakistan for over a decade, working with government agencies, development authorities, NGOs and private developers to design, build and rehabilitate the infrastructure communities depend on.

Our public health engineering team is well-versed in modern design technology and has the capability to adapt international standards to Pakistan’s socio-economic conditions. We have secured more than 20 projects in this sector in Pakistan and internationally, with a combined project value exceeding USD 0.5 million in professional fees alone.

Public health engineering is the branch of civil engineering that deals with infrastructure for clean water supply, sewage treatment, storm water drainage, and solid waste management. It is essential for preventing waterborne disease and maintaining community health standards. Arch-Tech provides a full range of public health engineering services across Pakistan.

Yes. Our public health engineering team designs domestic and industrial sewage treatment plants of all capacities, from small community-level STP systems to large municipal wastewater treatment facilities.

Yes. Arch-Tech has designed solid waste collection and disposal systems, sanitary landfills and composting facilities for municipalities and development authorities across Pakistan.

Yes. We provide detailed plumbing design for all building types, including hospitals, schools, universities, offices, and industrial buildings — covering water supply, drainage, fire protection, and sanitation systems.

For rural water supply projects, Arch-Tech conducts hydrogeological surveys, community demand assessments, and designs appropriate water supply systems — including gravity-fed schemes, hand pump programmes, and solar-powered pumping systems — tailored to the socio-economic realities of rural communities.
