Frequently asked questions.

No. The objective is broad coverage through a qualified range of host tanks and adapters. Condition, geometry, access, usable treatment and solids-storage volume, ventilation and the downstream field must all be reviewed.

No additional wastewater tank or pod is part of the base retrofit concept. Suitable dry equipment housing and existing approved dosing infrastructure may still be needed. A site that cannot meet the configuration requirements may not qualify.

No. The proposed core is an aerobic biological process supported by fixed media, with controlled circulation and protected solids separation. Required coarse protection or field filtration performs a different job.

Not yet. Approximately 600 US gallons per day is an initial development duty. A rating requires testing of the complete configuration at defined wastewater loads and operating conditions.

No. The goal is to reduce avoidable intervention and develop hardware servicing around normal pump-out where evidence and approval permit. Pumping, required inspections, wear components and purchased-pump care remain; a three-to-five-year interval is not established.

No. Pumps are the explicit purchased exception to our original-assembly manufacturing plan. The air-pump or blower production arrangement remains under evaluation.

Yes. The Subfield retrofit enhanced treatment system is sold directly by Subfield. There is no online store or checkout yet: send an order request and the Subfield team handles the order from there, starting with whether your existing tank qualifies. A request is not a confirmed order, a reservation or a compatibility decision. No payment is taken on this website, and prices, availability and timing are not published here.

Anyone can buy the Subfield retrofit enhanced treatment system, but we strongly prefer that it be installed by a licensed septic or onsite wastewater professional. Local codes and permit requirements apply; check with your local health department or permitting authority before installing.

Essential treatment and required local alarms are being designed not to depend on cloud access or a subscription. A power outage is different and must follow the qualified, finite-reserve failure plan.

This page explains one part of the Subfield retrofit enhanced treatment system, which is sold directly by Subfield through an order request. Which parts an installation includes is set by its reviewed configuration; conditional components are not automatically included. No price, inventory or checkout is published, and an inquiry is not a purchase or reservation.

The actual host tank, product revision, electrical or hydraulic class, installed role and qualified configuration must be reviewed. A familiar name or matching connector does not establish compatibility.

Anyone can buy the Subfield retrofit enhanced treatment system, but we strongly prefer that it be installed by a licensed septic or onsite wastewater professional. Local codes and permit requirements apply; check with your local health department or permitting authority before installing. No-entry service is a design goal, not authorization for unreviewed structural or electrical work.

No. Qualified procedures, exact ratings, required care and reviewed commercial terms follow product release. Development objectives are not shipping specifications.
