Water Protection Projects and Polices

Protecting water isn’t just about how much we use - it’s also about keeping it clean and healthy for people, wildlife, and the environment.

In New Westminster, this means managing how rainwater flows through the city, reducing pollution, and protecting natural areas along rivers and waterways. Here are some of the ways this work happens:

Protecting Rivers and Natural Areas

Areas along rivers, streams, and ditches (called riparian areas) play an important role in keeping water clean and supporting fish and wildlife.

A Riparian Assessment Area includes land within 30 metres of a stream boudary (the high water mark or floodplain). Under provincial regulations and the City's bylaws, a stream includes rivers, creeks, and ditches.

Properties within this area require environmental review before development. A qualified environmental professional will assess the site and determine appropriate setbacks to protect water quality, reduce erosion, and support fish and wildlife habitat.

Erosion and Sediment Control: Managing Soil Disturbance and Runoff

Construction and land development can cause dirt, debris, and pollutants to wash into storm drains and waterways - especially during rain.

To prevent this:

• Property owners, developers, and builders must plan ahead to control runoff and keep sediment on-site
• Erosion and sediment control measures (like barriers, coverings, and drainage controls) are required
• Larger construction projects must have detailed plans and trained supervisors in place

These steps help keep nearby rivers and streams cleaner during construction.

Resources:

• Erosion & Sediment Control Bylaw No. 7754, 2016
• Concrete Works & City Requirements for owners, developers or builders
• Land Development Guidelines for the Protection of Aquatic Habitat.

Reducing Sewer Overflows

Some older parts of the city still use combined sewer systems, where rainwater and wastewater share the same pipes.

During heavy rain, these systems can overflow, and diluted wastewater may enter local waterways.

To reduce this:

• The City is gradually replacing older combined sewers with separate systems for wastewater and stormwater
• A large storage tank captures excess flow during storms and holds it until it can be safely treated

This work helps protect the Fraser River and Brunette River, especially during heavy rainfall.

Managing Rainwater (Stormwater)

Rainwater that falls on roofs, roads, and sidewalks can pick up pollutants before entering storm drains and local waterways.

The City’s Integrated Stormwater Management Plan focuses on:

• Slowing down and filtering rainwater where it falls
• Reducing flooding and erosion
• Improving water quality before it reaches rivers

This includes using green infrastructure, such as:

• Rain gardens
• Permeable surfaces that absorb water
• Landscaped areas that naturally filter runoff

These approaches mimic how water moves in nature and help keep our waterways healthier.
