Metcalf & Eddy recently developed a computerized distribution system model for the
Metropolitan District Commission (MDC) in Hartford, Connecticut. In order to account
for the variations in demand, the system was divided into twelve demand zones roughly
corresponding to the pressure zones with larger zones subdivided based on additional
geographical factors. Large users and un-metered usage were considered separately. Each
demand zone was characterized by a unique demand pattern and seasonal multiplier. A
system-wide water budget was utilized to aid calibration and track total hourly demands in
each demand zone while maintaining the overall system demand.
Utilizing this model, M&E conducted a thorough analysis of the MDC's system and
developed a program of improvements to address system deficiencies. Includes figures.
