Civil Works - STP

Civil works for a Sewage Treatment Plant (STP) refer to the structural and infrastructural components that support the installation, operation, and maintenance of the plant. These works include the construction of foundations, tanks, chambers, retaining walls, drains, and associated civil infrastructure required for the effective treatment and disposal of wastewater.

Civil Works - STP

Service Overview

Civil works for a Sewage Treatment Plant (STP) refer to the structural and infrastructural components that support the installation, operation, and maintenance of the plant. These works include the construction of foundations, tanks, chambers, retaining walls, drains, and associated civil infrastructure required for the effective treatment and disposal of wastewater. Civil works form the backbone of an STP, ensuring the structural strength, durability, and hydraulic efficiency of the system.

Our Process

1

Site Preparation

Site leveling, excavation, and layout marking as per design drawings.

2

Foundation Work

Laying reinforced concrete foundations for tanks, reactors, and equipment.

3

Tank Construction

Building primary, secondary, and tertiary treatment tanks using RCC.

4

Waterproofing & Plastering

Internal and external waterproof coatings to prevent leakage and corrosion.

5

Chamber & Pipeline Installation

Construction of manholes, inlet/outlet chambers, and laying of sewer pipelines.

6

Equipment Base Preparation

Providing pedestals and mounting bases for mechanical and electrical equipment.

7

Finishing Works

Paving, fencing, access roads, and landscaping around the plant.

8

Testing and Commissioning

Hydraulic and leakage tests before commissioning mechanical systems.
