Executive Summary
This demo report shows a typical water analysis for a property in Silves, Algarve. The region is supplied by Águas do Algarve. Based on official data from 2025/2026, 3 main risks have been identified that should be considered before purchasing a property.
Water Quality Parameters
Based on official data from Águas do Algarve and Edital Silves (2025/2026):
| Parameter | Measured Value | EU Limit | Assessment |
|---|---|---|---|
| Chlorine (Free Residual) | 0.45-0.60 mg/l | ≤ 0.2 mg/l (recommended) | ELEVATED |
| pH Value | 7.2-7.8 | 6.5-9.5 | NORMAL |
| Total Hardness | 12-15 °dH | N/A | MODERATELY HARD |
| Nitrate | 28-35 mg/l | ≤ 50 mg/l | NORMAL |
| Bacteria (E. coli) | 0 CFU/100ml | 0 CFU/100ml | GOOD |
Identified Risks
🔴 Risk #1: Elevated Chlorine Levels
Problem: Chlorine residual of 0.45-0.60 mg/l exceeds the recommended 0.2 mg/l.
Impact:
- Noticeable odor and taste
- May irritate skin and mucous membranes (showering, bathing)
- Affects taste of coffee and tea
- Reduces cooking quality
Recommended Action: Install activated carbon filter or 3-stage filter system (approx. €300-800)
🟡 Risk #2: Regional Water Scarcity
Problem: Algarve suffers from increasing water scarcity (APA Report 2025).
Impact:
- More frequent water restrictions in summer
- Particles and sediment due to stressed infrastructure
- Potential pressure fluctuations
- Possible increased water prices in future
Recommended Action: Rainwater harvesting system for garden (€3,000-8,000) + sediment pre-filter (€150-400)
🟢 Risk #3: Limescale Buildup (Moderately Hard)
Problem: Water hardness of 12-15 °dH can cause limescale deposits long-term.
Impact:
- Shortened lifespan of household appliances
- White deposits on fixtures
- Increased cleaning and maintenance effort
Recommended Action: Optional - water softener system (€1,500-3,500) or regular descaling
Our Recommendations
💧 Short-term (before moving in)
- Install activated carbon filter system (Priority: HIGH) - Removes 99% of chlorine, improves taste immediately
- Sediment pre-filter at main connection - Protects against particles from stressed infrastructure
- Have water tested - Laboratory analysis before signing contract (€150-300)
🏡 Medium-term (6-12 months)
- Plan rainwater harvesting system - For garden irrigation and toilets (reduces water costs by 30-40%)
- Evaluate water storage - Useful during frequent restrictions (1,000-5,000 liters)
- Consider water softener - Worthwhile with many household appliances
🔬 Long-term (Optional)
- Check well option - On large property for garden irrigation (€5,000-15,000)
- Reverse osmosis system - For absolutely pure drinking water (€800-2,500)
- Maintenance contract - Annual water tests and filter service (€200-400/year)
Cost Overview
| Measure | Priority | Cost | Benefit |
|---|---|---|---|
| Activated Carbon + Sediment Filter | HIGH | €450-1,200 | Immediate water quality improvement |
| Laboratory Water Test | HIGH | €150-300 | Legal protection before purchase |
| Rainwater System | MEDIUM | €3,000-8,000 | 30-40% water cost savings |
| Water Softener | LOW | €1,500-3,500 | Protection for household appliances |
💰 ROI Calculation
Minimum Investment: €600-1,500 (Filter + Water Test)
Avoided Costs:
- Remediation for contaminated water: €15,000-30,000
- Premature appliance replacement: €3,000-8,000 over 10 years
- Health costs (skin issues from chlorine): incalculable
Break-Even: After 2-3 years
