Replacement of Lead Pipes for Safe Drinking Water
Lead water pipes were widely used in homes and buildings in the Netherlands until the 1960s. It is now known that lead slowly dissolves into drinking water and is harmful to health with prolonged intake, especially for young children and pregnant women. Therefore, it is strongly recommended – and in some cases legally required – to replace lead pipes with safe, modern alternatives such as copper, plastic (PE, PEX), or stainless steel.
1. Health risks of lead pipes
- Lead intake via drinking water can lead to developmental disorders in children.
- Pregnant women are at increased risk of complications during pregnancy.
- Long-term exposure in adults can lead to kidney problems, high blood pressure, and other health complaints.
- RIVM advice: lead concentration in drinking water must be as low as possible; the standard value is 10 micrograms per liter.
2. Identifying lead pipes
- Color and material: dull gray and soft metal that bends easily.
- Construction period: common in homes built before 1960.
- Test method: scratching the surface reveals shiny silver-colored metal.
- In many old buildings, lead is still present in the main water pipe or connections behind the water meter.
3. Legal and normative frameworks
- Drinking Water Act and Water Supply Decree: new installations may not contain lead.
- Building Decree 2012: requirements for safe drinking water installations.
- NEN 1006: standard for the design and execution of pipe networks.
- Housing associations and landlords are obliged to ensure a safe drinking water installation; tenants can demand replacement in case of health risks.
