24 hour composite sample definition
A composite sample is a single sample volume constructed of multiple individual samples (aliquots) taken over a specific period of time or volume of flow (period of interest). “Time Paced" Composite samples are taken at uniform intervals of time over the period of interest.

Discrete and composite sampling can be used with on-site, grab, or automatic samples but most automatic sampling equipment is designed specifically for one method or the other. Time-weighted samples, however, can only be collected as discrete samples because each sample represents a different volume of stormwater.
Global Water's wastewater sampler takes time weighted composite samples, backflushes after each sample, and is rugged and reliable.
a) The sampler should be able to take time-weighted composite samples, for example, sampling over different time intervals of flow activity for constant flow rates
