Water sourcing challenges associated with hydraulic fracturing
Water sourcing challenges associated with hydraulic fracturing

Centralization provides the treatment and reuse of flowback wastewater from a number of wellheads when the wells are hydraulically fractured for the long-term, full life cycle of the wells. Furthermore, a consolidated system can more easily access and use alternative water sources, such as that from municipal wastewater facilities, which may be extremely difficult to access.
