FAQ - Tank Requirements

What type of septic tank are required?

Tanks with two chambers are required – a chamber for regular water storage called a sludge chamber and a pump chamber for pump and emergency storage.

What is the main difference between the tanks required for this project and the one required under Alberta Private Sewage Systems Standard of Practice (APSSSOP) 2015?

The basic difference is that the Municipality’s design requires 24 hours storage volume on top of the volume requirements established under the Alberta Private Sewage Systems Standard of Practice (APSSSOP) 2015.

How is the size of tank determined?

The sewage from your household will go directly to the sludge chamber. The volume of this chamber is to be determined as per the requirement of Alberta Private Sewage Systems Standard of Practice (APSSSOP) 2015.

The pump chamber accepts the liquid from the first chamber and it is sized for pump operating volume plus one day of emergency storage.

Tanks installation steps

Step 1: Please engage a certified installer to design the system based on your needs and the emergency storage requirements of the Municipality or call the Safety Codes branch at 780-743-7813.

Step 2: Apply for the permit to be approved before starting any construction. The RMWB’s Safety Codes branch in consultation with the Engineering Department will review the design for its compliance under the Alberta Private Sewage Systems Standard of Practice (APSSSOP) 2015 as well its compatibility with the proposed Rural Water and Sewer Servicing design. No construction should start without the approved permit.

Step 3: Install/construct the system complying with the manufacturing requirement, Alberta Private Sewage Systems Standard of Practice (APSSSOP) 2015 and RMWB’s Engineering Servicing Standards and Development Procedures 2016.

Step 4: Call Safety Codes to inspect before backfilling. After a final compliant inspection a Permit Services Report will be issued.

Step 5:  If you want to install this service pipe on your own then it will be installed as per the requirement of service connection noted in the RMWB’s Engineering Servicing Standards and Development Procedures 2016 and the installation shall be inspected prior to the backfill.

Step 6: Maintain the system as per the applicable requirements.
