Project Overview:

Location: Indian Coast Guard premises, Visakhapatnam, India

Capacity: 1,50,000 liters per day (approx. 150 m³/day)

Executing Agency: Central Public Works Department (CPWD)

Regulatory Compliance: Followed all norms suggested by Pollution Control Board

Background: Visakhapatnam, a key port city on the eastern coast of India, hosts various defense establishments, including the Indian Coast Guard. As part of its infrastructure development and environmental stewardship initiatives, the Indian Coast Guard identified the need for a modern sewage treatment plant (STP) to manage wastewater effectively within its premises. The project was essential not only to comply with environmental regulations but also to mitigate pollution and ensure sustainable water management practices.

Challenges:

Limited Space: The installation of a robust sewage treatment system within the constrained area of the Coast Guard premises posed spatial challenges.

Environmental Compliance: Strict adherence to pollution control norms set by the Pollution Control Board (PCB) was mandatory to avoid any adverse environmental impact on the surrounding areas, including marine ecosystems.

Operational Efficiency: Ensuring the STP could handle fluctuating loads effectively, considering the dynamic operational nature of the Indian Coast Guard facilities.

Solution:

Design and Technology: CPWD, in collaboration with environmental engineering experts, designed a compact sewage treatment plant capable of treating 1,50,000 liters of wastewater per day. The design integrated advanced treatment processes suitable for handling domestic sewage, including screening, biological treatment (activated sludge process), and tertiary treatment (such as disinfection).

Space Optimization: Given the space constraints, the STP was designed vertically, utilizing advanced compact treatment units and efficient layout planning to maximize treatment capacity within the available footprint.
