Taking Intermittent multipoint samples, sealing them and organising Lab testing on Annual Contract basis works well until the constituents of water that have fluctuating parameters get detected or at least their range gets known. Seasonality of raw water intake is a big factor. I sense that you shall have to source Multiple Detection Systems for ONLINE checks...even for critical parameters like BOD, DO, TDS , PH value, Bacteria count, Trace Elements, etc..
