Installation Of Septic Tanks & Sewage Treatment Plants Nationwide

Installation of Sewage Treatment Plants (STPs) involves a systematic process that includes planning, design, construction, and commissioning. At Waste Water we can offer Nationwide Installation through either ourselves or our approved contract partners.

Here’s a step-by-step guide outlining the process:

🧱 1. Planning and Site Selection

Site Analysis: Evaluate proximity to the sewage source, land availability, topography, and environmental impact.

Permissions: Obtain approvals from local authorities (e.g., Pollution Control Board, Municipal Body).

Design Parameters:

Population served (present and future)
Daily sewage flow rate (in KLD – kilo liters per day)
Type of sewage (residential, industrial, mixed)

📐 2. Designing the Plant

Treatment Technology Selection:

Primary: Screening, grit removal, sedimentation
Secondary: Biological treatment (e.g., Activated Sludge Process, MBBR, SBR)
Tertiary: Filtration, disinfection (UV, chlorination)

Components to Design:

Inlet chamber
Equalization tank
Aeration tank
Secondary clarifier
Sludge handling units (e.g., sludge drying beds, dewatering units)
Treated water storage tank

🚧 3. Civil and Mechanical Construction

Excavation and Civil Work: Construction of tanks and chambers using RCC or prefabricated materials.

Mechanical Installation:

Pumps and blowers
Diffusers and mixers
Screens and grit separators

Plumbing and Piping: Laying pipelines for inlet, outlet, sludge, and recycled water.

⚙️ 4. Electrical and Automation Work

Installation of:
Control panels
Motors and drives
Sensors and flow meters

🧪 5. Testing and Commissioning

Dry run of individual components
Wet testing with water, followed by actual sewage
Monitoring BOD, COD, TSS, and pH levels
Adjusting parameters for optimal performance

📄 6. Documentation and Handover

Operating and Maintenance Manuals (O&M)

Training for plant operators

Compliance certification (e.g., from Pollution Control Board)

Annual Maintenance Contract (AMC) offer
