1.1 Stage 1: Raw Water Abstraction & Screening

    style C fill:#0D152D,stroke:#38BDF8,stroke-width:2px,color:#fff

💡 How It Works:

Submerged multi-stage intake pumps extract raw surface water from natural reservoirs. Heavy stainless-steel bar screens filter out coarse floating debris before delivering untreated water to the chemical treatment station.

    style D fill:#0D152D,stroke:#38BDF8,stroke-width:2px,color:#fff

💡 How It Works:

Polyaluminum Chloride (PAC) and alum chemical coagulants are injected into a high-speed flash mixer. The high shear turbulence neutralizes particle charges, encouraging fine silt and organic matter to bind into micro-flocs.

1.3 Stage 3: Sedimentation & Clarification

    style D fill:#0D152D,stroke:#EF4444,stroke-width:2px,color:#fff

💡 How It Works:

Flocculated water enters Lamella plate clarifiers where gravity pulls dense particulate flocs downward onto inclined honeycombs. Heavy sludge is automatically scraped to bottom hoppers while clean water overflows into the filter channel.

    style E fill:#0D152D,stroke:#10B981,stroke-width:2px,color:#fff

💡 How It Works:

Clarified water flows through multi-layered deep beds composed of graded anthracite coal, fine silica sand, and garnet gravel. Microscopic suspended particles and turbidity are trapped, yielding ultra-clear water (< 0.15 NTU).

    style D fill:#0D152D,stroke:#00F5D4,stroke-width:2px,color:#fff

💡 How It Works:

Sodium hypochlorite (chlorine) and hydrated lime are dosed into contact tanks. Chlorine destroys microbial pathogens, while lime stabilizes the pH to prevent pipeline corrosion before entering municipal storage.

    style D fill:#0D152D,stroke:#38BDF8,stroke-width:2px,color:#fff

💡 How It Works:

Disinfected water is stored in underground clean-water reservoirs (clearwells). High-efficiency Variable Frequency Drive (VFD) pumps pressurize trunk mains dynamically to meet fluctuating city demand.

    style E fill:#0D152D,stroke:#A855F7,stroke-width:2px,color:#fff

💡 How It Works:

Pressure Reducing Valves (PRVs) step down high trunk pressure before entering isolated District Metered Areas. DMA isolation allows real-time leak detection and precise sector pressure management.

    style E fill:#0D152D,stroke:#EF4444,stroke-width:2px,color:#fff

💡 How It Works:

Ultrasonic smart meters stream real-time consumption data to the Flask SCADA engine. The automated billing module calculates monthly tariffs, dispatches digital invoices, and manages enforcement locks.
