Total lead pipe replacement

As an alternative to random daytime sampling, but preferably as a supplementary monitoring method, stagnation sampling at selected properties can provide useful information on the effectiveness of dosing ortho-phosphate for reducing plumbosolvency. This approach is not relevant if total lead pipe replacement is undertaken as the sole corrective measure. 

Attempts at total lead pipe replacement that include internal domestic lead pipes have failed because of a lack of cooperation from home-owners. 

Unit costs of total lead pipe replacement... 

Units costs are therefore likely to range from 1,000 to 4,000 for total lead pipe replacement per property. 

Therefore, the cost of total lead pipe replacement will be between 15 M and 60 M. 

Total lead pipe replacement assuming a cost of 15 M spread over 10 years... 

Units costs are likely to range from around 500 to 2,000 per lead service pipe replaced, depending on local labour costs and ground conditions (particularly the extent of paved and road surfaces). In Brussels (Belgium) over the period 2002 to 2008, 38,000 lead connections (owned by the water company) were replaced at a total cost of 15M, averaging 395 per connection. In the Hague...
