Water Provisioning

Water provisioning refers to supplying treated water at scale to communities, industrial parks, or regions that lack access to centralized municipal infrastructure. Unlike a city water system, a provisioning project may draw from surface water, brackish wells, or brackish coastal aquifers and must deliver finished water meeting drinking water standards to distributed end points. AMPAC USA designs large-scale provisioning systems starting at 100,000 GPD and scaling to multi-million GPD installations.

Viable sources include surface water from rivers and reservoirs, shallow and deep groundwater wells, brackish coastal aquifers, and seawater for coastal communities with no alternative freshwater. Each source requires a different treatment train and energy budget. Seawater provisioning at scale requires high-pressure RO operating at 800-1,000 psi with energy recovery devices to keep operational cost per gallon manageable, typically between $0.003 and $0.008 per gallon in energy cost alone.

AMPAC USA large provisioning systems include online monitoring of turbidity, pH, TDS, free chlorine residual, and flow rate at the treatment plant output, with data logged continuously and alarmed against threshold limits. Distribution point sampling for microbial quality follows WHO and EPA guidelines for community water systems. Remote SCADA connectivity allows centralized monitoring of multiple system points without constant on-site staffing.

Long distribution networks require a chlorine residual of 0.2-0.5 ppm at the farthest distribution point, which means dosing 0.5-2.0 ppm at the treatment plant depending on distribution time and pipe materials. Sodium hypochlorite dosing systems are standard for provisioning scale, with on-site sodium hypochlorite generation becoming cost-effective at very large scale or in locations where chemical supply is unreliable. AMPAC USA includes chlorine dosing skids integrated with the main treatment system in all provisioning plant designs.

A 500,000 GPD provisioning plant typically requires 6-9 months from signed contract to commissioning, assuming feed water quality data is available at project start and civil works proceed in parallel with equipment fabrication. Source water testing, process design, permitting, and fabrication each take 2-3 months, and they overlap in a compressed schedule. AMPAC USA maintains equipment in stock for standard configurations and can reduce lead time for urgent provisioning projects.
