Estimation of Population Equivalent
The UWWTD defines population equivalent (PE) as a measurement of organic biodegradable load which shall be calculated on the basis of “the maximum average weekly load entering the treatment plant”. This project was designed to test the statistical properties of such PE calculations and compare them with PE estimates used for other reporting purposes. In making these comparisons, an understanding of the factors influencing PE estimation was developed together with an insight into the varying interpretations adopted by different Water Companies. Relative to the other methods analysed, the UWWTD method for estimating PE showed major practical difficulties and inconsistent results.
