Key Septic System Regulations
- Minimum Lot Size: If your property has both a private well and a septic system, Arizona regulations generally require a minimum lot size of 1 acre.
- Property Transfer: Arizona law requires a septic system inspection within 6 months prior to the sale or transfer of a property. The buyer must then file a Notice of Transfer (NOT) within 15 days of closing.
- Maintenance: Systems should typically be professionally pumped every 3–5 years to maintain performance and prevent clogs.
In Apache County, the minimum septic tank size is primarily determined by the number of bedrooms and plumbing fixtures in the home, per Arizona Administrative Code (AAC) R18-9-A314.
Minimum Capacity by Bedroom Count
In Apache County, the minimum size of a wastewater septic tank for a standard home is 1,000 gallons.
Residential Septic Systems
Generally, there are two types of wastewater systems: a home or building connected to a municipal sewer network with a centralized water treatment plant, or an on-site septic system (Wastewater Treatment System).
We stock the 1000-gallon wastewater septic tanks on our lot, and they are ready and waiting for delivery.
There are other sizes available, which are not in stock, but we can certainly get them right away.

Septic, Chambers, Parts, and Installation
SJ Portables offers a wide range of septic tanks, drain field chambers, and all the septic parts for your residential Wastewater Treatment needs.
For those not familiar with chambers used for septic systems... chambers are an alternative to traditional gravel-filled trenches in the drain field (also known as the leach field).
They are essentially large, bottomless plastic "troughs" or arched shells that are buried underground to handle wastewater after it leaves the septic tank.
Whether for new construction, the addition to, or the replacement of an older system, SJ Portables has the solution you need and the service you want.
Our septic tank offers:
- Corrosion-resistant polyethylene used in tank construction will outlast traditional septic tank materials, such as concrete and steel.
- Lightweight plastic construction allows for easy storage and delivery. Installers can handle it without special equipment.
- Tanks can be installed with 6 to 36 inches of soil cover, depending on the product selected.
- Engineered for strength. Low-profile Dominator design, which requires less digging and helps to avoid high water tables.
- The NexGen D2 design requires absolutely no water for backfill, thereby saving time during installation.
Count on SJ Portables to ensure your Septic Systems are top-notch.
Don't risk choosing inferior products or services for your essential septic system; your residence's septic system is too important!
We stock a great variety of septic tank products and parts to serve your Residential Wastewater Treatment.
Permitting and Installation Process
Installing a septic system involves a multi-step regulatory process to ensure groundwater protection and public health:
- Notice of Intent (NOI) to Discharge: Before starting construction, you must submit an application including thorough plans, site evaluation data, and fees to obtain a construction authorization.
- Site Evaluation: A professional (such as a registered engineer, sanitarian, or licensed contractor) must conduct a Uniform Site Investigation. This includes soil absorption testing (percolation tests) and subsurface checks for limiting conditions such as bedrock or high groundwater levels.
- Inspections: The county typically conducts at least two inspections during the construction phase to verify that the system matches the approved plans.
- Discharge Authorization: After construction is complete and inspected, you must submit a Request to Discharge to receive final approval to use the system.
For official inquiries or to start a permit application, you can contact the Apache County Environmental Services Division at (928) 337-7607.
