Budget estimate

$500,000 – $1,500,000

No budget is disclosed, but a full‑plant electrical upgrade for a municipal water treatment facility typically ranges from half a million to a few million dollars depending on equipment, labor, and design requirements. Assuming a medium‑size plant, an estimate of $500,000‑$1,500,000 is reasonable. Factors influencing the range include the extent of existing infrastructure, required safety upgrades, and any ancillary control‑system integration.
