Finally, it was not possible to predict a filter’s current hydraulic conductivity from<br />
factors such as its size, the catchment size, or the inflow volume. The initial specified<br />
hydraulic conductivity is the critical determinant <strong>of</strong> its long-term hydraulic behaviour.<br />
Whilst this provides little help in predicting system lifespan or maintenance<br />
requirements, it does rein<strong>for</strong>ce the criticality <strong>of</strong> specifying the correct hydraulic<br />
conductivity <strong>of</strong> <strong>systems</strong> at the time <strong>of</strong> construction. Perhaps most importantly,<br />
guidelines do not pay due attention to the importance <strong>of</strong> translating design<br />
specifications through the construction process. Contract hold-points should in place to<br />
ensure testing <strong>of</strong> the media during construction.<br />
