Everything You Need to Know About Surrey’s Sanitary Systems


The City of Surrey in British Columbia is a beautiful and bustling city with over 580,000 people. The City is home to a variety of businesses and industries, as well as a number of parks and recreation areas.

With so many people living and working in Surrey, it’s no wonder that the City’s sanitary system is one of the most crucial infrastructures. The system is consist of a network of sewers, pumps, and treatment plants that work together to keep Surrey’s water clean and safe.

In this article, we’ll take a closer look at Surrey’s sanitary system and how it works to keep the City clean. We will also talk about the inspections and maintenance requirements to keep the system running smoothly.

Surrey Sanitary Sewer System

The Surrey sanitary sewer system is a network of underground pipes and pumps that collect and transport sewage from homes and businesses to treatment plants. The system can handle both wet weather and dry weather flows.

The sewer system consists of up to 1500 kilometres of pipe, ranging in size from 300mm to 1800mm in diameter. The system has two types of pipe: gravity sewers and force mains.

Gravity sewers are the most common type of sewer pipe so they compose the majority of the system. These pipes rely on gravity to move sewage from homes and businesses to treatment plants.

While most treatment plants use force mains for areas such as steep hills or low-lying areas where gravity sewers are not possible. These pipes use pumps to move sewage through the system.

Where Does Surrey Waste Water Go?

The Surrey sanitary sewer system transport sewage from homes and businesses to one of three treatment plants including: the Annacis Island Wastewater Treatment Plant, the South Surrey Wastewater Treatment Plant, or the Lulu Island Wastewater Treatment Plant.

The Annacis Island Wastewater Treatment Plant is the largest of Surrey’s three treatment plants. The plant treats an average of 250 million litres of sewage per day.

The plant uses a variety of treatment processes to remove pollutants from sewage, including primary treatment, secondary treatment, and tertiary treatment.

Primary treatment removes solid materials from sewage using screens and grit tanks. Secondary treatment removes dissolved and suspended materials from sewage using bacteria and chemicals. The tertiary treatment removes any remaining pollutants from sewage using UV light or ozone gas. After the sewage treatment, the treatment plant will be discharging it into the Fraser River.

How is Surrey’s Sanitary Sewage System Maintained?

The Surrey sanitary sewer system is inspected and maintained regularly to ensure that it is functioning properly. Conducting inspection activities are typically on an annual basis, although more frequent inspections happen in areas with high use or where there are concerns about the system’s condition.

Conducting maintenance activities is a proactive way to address to avoid problems in the future. Inspection and maintenance activities include:

  • Smoke Testing: This is to identify leaks in the sewer system. A non-toxic smoke is injected into the sewer system and allowed to escape through any cracks or holes in the pipes.
  • Camera Surveys: The city is performing this regularly in order to know the condition of the sewer pipes. By inserting a small camera into the sewer pipe and using it to take pictures of the interior of the pipe.
  • Pipe Cleaning: The treatment facilities are conducting pipe cleaning regularly in order to remove any build-up of materials from the sewer pipes. They use high-pressure water jetting or rodding to clean the pipes. They are also removing tree roots from the pipes using this method.
  • Repair and Rehabilitation: The maintenance team is repairing damaged pipes using a variety of trenchless methods, including pipe relining and pipe bursting. In this process, the maintenance team will no longer require to dig up your entire lawn just to fix a small leak in the sewer pipe.

Surrey Resident’s Responsibilities To Maintain The Sanitary Sewer System

As a Surrey resident, you play an essential role in maintaining the sanitary sewer system. You can help keep the system functioning properly by doing the following:

  • Only flush toilets and pour drains with human waste and toilet paper. Do not flush or pour any other materials, such as diapers, sanitary napkins, condoms, grease, coffee grounds, or cigarette butts down the toilet or drain.
  • Do not dispose of cooking oil or grease by pouring it down the drain. Cooking oil and grease can solidify in the sewer pipes and cause blockages. Instead, dispose of cooking oil and grease in a container and put it in the garbage.
  • Do not plant trees or shrubs near sewer pipes. The roots of trees and shrubs can grow into the sewer pipes and cause blockages.

  • Do not pour any hazardous materials down the drain, such as cleaning products, paint, or oil. Hazardous materials can harm the bacteria that are used to treat sewage.
  • If you notice any problems with the sewer system, such as sewage backing up into your home or water pooling in the street, contact the City of Surrey immediately.
