Typical water infrastructure connections aren't necessary as water can be brought in by any means available.
Much of the wastewater is reclaimed and recirculated to a properly balanced nitrate- and phosphate-rich irrigation water or further polished to potability and ensured purity by utilizing the modern practice of resilience throughout the water influent systems.
Advanced Wastewater Treatment is integral to the the overall design of the shelter systems.
Original sources of water are tested and treated for excess or harmful mineral content, unhealthy organic compounds and pathogens.
The shelter system always includes separate grey and black water treatments. The greywater is treated as typical sewage, but further treated beyond the secondary treatment phase. In order to safeguard against the likelihood of fecal matter entering the graywater effluent from households and other buildings prior to treatment, utilization of only one system is unadvisable. The notion of "resiliency" is properly applicatory to wastewater treatment designed to be returned to potability. In case of any system failure, the subsequent and alternative treatments serve to preclude the return of foul tastes, odors and pathogens to water returned to households and office/industrial buildings as clean drinkable water. The quality of the water returned to the original user is consistnetly higher than most of that which is currently available through our taps. Nanofiltration and a secondary, optional decorative UV waterfall fountain provide final treatments prior to any manor of consumption within households, thereby providing ample safety from disease while offering an optional visually-pleasing in-home water feature.
Surpassing the effluent quality of secondary treatment, a resilient battery of tertiary treatments include the following: activated carbon filtration and ultrafine particulate removal, ozonation, UV exposure, and concentrated (parabolic dish) solar distillation. While only one of the advanced treatments would be typically utilized for release to the environment in the case of, the subsequent treatments are further refinement of each previous treatment's effluent.
Blackwater has its own primary and secondary treatments prior to air treatment and further dewatering over fiter media within a chamber under vacuum. This primes the solids precipitated from the sludge prior to its conveyance to the pyrolysis unit.
Backwash from all solids filters for both greywater and blackwater systems ultimately find their way to the sludge dewatering pretreatment described above.
In order to most effectively deal with the dewatered sludge, avoiding a dismissive landfill solution, solids waste dried to <12% moisture content are pyrolyzed, yielding many eminently useable and even saleable byproducts.
