<strong>Chlorine</strong> <strong>Monitoring</strong> <strong>and</strong> Dechlorinating <strong>Techniques</strong> H<strong>and</strong>book<br />
provides a guide to increasing the size of the holding pond with the size of the pipe or flow<br />
rate.<br />
The banks of the pond should be vegetated or armoured with rip rap in order to prevent bank<br />
erosion over time. In addition, there should be a 0.5 m high freeboard around the entire pond.<br />
Figure 5-1 illustrates a plan view of a holding pond.<br />
