Water Tank Installation in Sri Lanka — Complete Guide to Water Storage Systems

Water Tank Installation in Sri Lanka

Reliable water storage is essential for every building in Sri Lanka. Selecting the right water tank, sizing it correctly, and installing it to standard ensures consistent supply and prevents contamination.

Types of Water Tanks

| Type | Capacity | Application | |------|----------|-------------| | GRP / FRP panel tank | 1,000–1,000,000 L | Commercial, industrial, high-rise | | Polyethylene (plastic) | 500–10,000 L | Residential, small commercial | | Stainless steel | 500–50,000 L | Potable water, food, pharma | | Reinforced concrete | 10,000+ L | Underground, large buildings | | Panel (sectional) | 1,000–500,000 L | Rooftop, plant room |

Sizing Guidelines

• Residential: 200–270 L per person per day
• Commercial office: 45–75 L per person per day
• Hotel: 350–450 L per room per day
• Hospital: 300–500 L per bed per day

Always size for 2–3 days of storage to cover supply interruptions.

Installation Process

1. Site assessment — structural load, access, overflow routing
2. Base preparation — level, reinforced platform or plinth
3. Tank assembly — panel/bolted or moulded, per manufacturer spec
4. Connection — inlet, outlet, overflow, drain, vent
5. Pump integration — booster pump and float switches
6. Testing — hydrostatic fill test, leak check
7. Disinfection — chlorination and flushing before commissioning

Common Issues

• Undersized tank causing frequent supply gaps
• Poor base leading to cracking
• No overflow or vent — contamination risk
• Inadequate access for cleaning
• Algae growth in transparent tanks

Maintenance

• 6-monthly internal cleaning and disinfection
• Annual inspection of seals and fittings
• Check anode (stainless) and cathodic protection
• Test float switches and level controls
