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. If you wish to qualify for the rebate please sign the Rebate Request Form (Please see question 5). 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: The Municipality’s contractor will install the service connection pipe from your tank to the property line as part of Municipal work at the time of hook up. 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 until the system is checked again for its suitability to be reused and hooked up to the Municipality’s Rural Water Sewer Servicing pipes. The hook up to the Municipality’s system is currently scheduled for May 2019. Only when the system is found adequate and reusable will it qualify for the rebate.

Is a rebate available and if so how much?

Some of the residences that are part of the rural water and sewer program will require installation of a septic tank on the property in order to connect to the main sewer line. A property owner may be eligible for a rebate where the owner chooses to install a compatible septic tank on the property himself/herself prior to the Municipality’s completion of the main sewer line, provided the septic tank meets all of the required specifications and its installation results in cost savings to the Municipality.

Rebate eligibility and amount will be determined in the sole discretion of the Municipality at the time of connection to the main sewer line. The Municipality may require the owner to submit any additional information that it deems necessary to determine rebate eligibility and amount. If an owner is eligible for a rebate, the rebate amount will be deducted from any service connection fees or other fees that may be imposed by the Municipality at the time of connection to the system or any other amounts that are owing or may become owing to the Municipality by the owner or in relation to the property. Please fill the Rebate Request Form and attach it with your permit application.
