CFD Modeling of Potable Water Storage Tank Mixing
Verifying a new ground storage reservoir avoids stagnant zones and meets water-age and disinfection targets before construction.
01 — ChallengeRisk of short-circuiting and stagnant zones
A municipal utility needed to verify that a new ground storage reservoir design would avoid short-circuiting and stagnant corners that could let chlorine residual decay below regulatory limits and water age exceed guidance.
02 — ApproachTransient tracer study across the full operating range
A transient scalar-transport model simulated inlet/outlet configurations, diurnal fill-draw cycles, and chlorine decay kinetics across the tank’s full operating range, from 25% to 100% level.

04 — Quantified ResultsBefore / After
| Parameter | Baseline | Result | |
|---|---|---|---|
| Dead zone volume | 22% | → | <6% |
| T90 mixing time | 5.4 hours | → | 1.8 hours |
| Chlorine residual, farthest point | below minimum in worst case | → | >0.2 mg/L, all scenarios |
05 — Business Impact
Verified the design before construction, avoiding field remediation and supporting regulatory approval on first submission.
