What utilities require upsizing to support multiple industrial lots?

When land is subdivided for industrial use, standard utility lines may no longer suffice. To ensure reliable service, compliance, and scalability, core utility systems must be upsized to meet the cumulative demand of all lots, particularly where multiple units may operate simultaneously with high consumption or discharge.

Below are the key utilities that typically require upsizing in industrial subdivisions:

1. Power Supply Infrastructure

• Why Upsizing Is Needed:
  
  • Individual lots may require 50 kW to several megawatts, depending on use.
    
  • Simultaneous load from machinery, HVAC, lighting, and automation systems.
    
• Required Upgrades:
  
  • Install a high-capacity transformer (e.g., 500 kVA to 5 MVA) near the park entrance.
    
  • Provision for HT lines (11 kV or 33 kV) with sufficient conductor sizing.
    
  • Feeder redundancy and space for future load scaling (dual source or backup generator corridors).

2. Water Supply and Storage Systems

• Why Upsizing Is Needed:
  
  • Industrial uses like processing, cooling, and cleaning demand higher and constant water flow.
    
  • Fire safety norms also require high-volume storage.
    
• Required Upgrades:
  
  • Wider pipelines (e.g., 100–250 mm diameter mains) across internal roads.
    
  • Overhead tanks or underground sumps with 1–5 lakh liter capacity.
    
  • Boosters or pressure regulation systems for evenly distributed service.

3. Sewage and Wastewater Drainage

• Why Upsizing Is Needed:
  
  • High volume discharge from multiple units, including both domestic sewage and process wastewater.
    
• Required Upgrades:
  
  • Larger sewer lines (200–400 mm) with minimum gradient and inspection chambers.
    
  • Provision for Common Effluent Treatment Plant (CETP) with 1000+ KLD capacity.
    
  • Separate lines for stormwater and greywater to avoid contamination.

4. Stormwater Drainage

• Why Upsizing Is Needed:
  
  • Large roof areas and paved surfaces create heavy runoff during rain.
    
• Required Upgrades:
  
  • RCC box culverts or open drains 600 mm and above with outfall to public drains.
    
  • Catch basins, sediment traps, and recharge pits to manage volume and quality.
    
  • Must be designed for 1-in-25 or 1-in-50 year storm events.

5. Telecommunication and Internet Infrastructure

• Why Upsizing Is Needed:
  
  • Modern industries require fiber-grade bandwidth, IoT connectivity, and backup lines.
    
• Required Upgrades:
  
  • Pre-laid duct banks or conduits across internal roads.
    
  • Central data distribution point with scalable capacity for future integration (e.g., 5G, cloud systems).
    
  • Provision for redundant cabling paths to prevent single-point failure.
