Completed in advance with the facility manager, licensed plumber, and water utility. One copy stored in the trailer binder; one copy kept on site.
Prevents treated water at 65–85 PSI from flowing backward into the municipal main (two valves in series when tapping upstream raw service-line tee).
Pre-installed tee with isolation valve on the building side of the closed street shutoff and meter/RPZ, upstream of ice, dish, and sinks.
MWTP-50C (Rev C): Direct pressurized feed into Port A (1.5") → PT-100 → PSV-100 (≥20 PSI) → RPZ-100 (ASSE 1013). Outages use Port B (2") from tanker or PWR-25 550-gal folding tank.
UF backwash & RPZ relief discharge (35–60 GPM on MWTP-50/50C; 300 GPM on MWTP-250) must enter the downstream sanitary sewer cleanout on the street side of the F.O.G. grease interceptor.
For pre-review by the local Environmental Health Inspector (FDA Food Code §§ 5-101.13 / 5-104.12) and Hospital Emergency Water Supply Plan (CMS 42 CFR § 482.15).

Virus-Rated UV Disinfection (186 mJ/cm²) | UV-401A (Duty) + UV-401B (Standby) 316L SS Amalgam Reactors UVDGM-validated at 40 GPM & 85% UVT + AIT-401 UVT Analyzer + FO-401 Flow Orifice | ≥ 186 mJ/cm² validated RED dose = 4.0-Log Virus Inactivation (per EPA LT2 Adenovirus table) + ≥ 4-log protozoa credit — eliminates 600-gal CT ground tank | Auto-starts standby UV-401B at >35 GPM or low intensity; opens XV-300 divert & closes XV-601 if dose < 186 mJ/cm² |
| 4. Free Chlorine Residual & Clearwell | NSF-60 12.5% NaOCl Dosing (P-502A/B) + Static Mixer SM-502 → 150-Gal Onboard Baffled Clearwell TK-601 + AIT-601 (Free Cl₂ / pH / °C) | Maintains 1.5–2.0 mg/L Free Chlorine residual throughout the restaurant plumbing (4-log virus already achieved by UV-401A/B) | AIT-601 & hardwired K-SAFE close XV-601 if Free Cl₂ < 0.5 mg/L or > 4.0 mg/L |
| 5. Potable Booster & Discharge RPZ | Duplex 3 HP 316SS VFD Boosters (P-601A/B) + 20-Gal Surge Tank + Fiscal Magmeter FIT-602 + Final Block XV-601 + 2" ASSE 1013 RPZ-602 | Maintains 65 PSI domestic pressure; AWWA C651 50 mg/L hose disinfection + certified lab Bac-T sample pulled at startup | High-pressure cutout at 85–90 PSI; double-block building isolation closed & tagged prior to tie-in |
Subject to AmeriPro Environmental Services completing fabrication, receiving state emergency-use plan approval, and executing a formal Standby Service Agreement, the undersigned facility expresses its intent to enroll the location(s) listed in Section A under the selected Standby Retainer Plan above (capped at max 10 restaurant locations per MWTP-50C / MWTP-50 trailer or max 3 hospitals per MWTP-250 trailer), with active emergency deployment billed at the schedule rate ($2,500 mobilization + $3,200/day for MWTP-50C / MWTP-50 on shore power, plus +$400/day when the PWR-25 generator trailer is dispatched; or $6,500 mobilization + $7,500/day for MWTP-250). This Letter of Intent is non-binding and may be included in AmeriPro's commercial lender underwriting package.
