Iron Ochre Deposits in Building Drainage Systems

Iron Ochre

Standard BNQ 3661-500
Iron Ochre Deposits in Building Drainage Systems - Parts I and II

The formation of iron ochre deposits is a common problem in building drainage systems that may result in the malfunction or complete failure of the system. The BNQ 3661-500 standard is intended to address the needs of those wishing to prevent or mitigate this problem. The document is divided into two parts:

Part I: Risk Assessment (for New Buildings) and Diagnosis (for Existing Buildings) of Iron Ochre Deposit Formation in Drainage Systems

Part II: Proposed Installation Methods for New and Existing Buildings

The standard is especially useful in assessing the risk of iron ochre deposit formation in situations that include the following:

  • real estate transactions;
  • construction of a new building on a vacant lot;
  • construction of multiple roads in a new housing development.
