Tanks-A-Lot Ltd.

Tanks-A-Lot Ltd. is a trusted manufacturer and supplier of concrete sewage holding tank systems for residential and commercial properties across Alberta and British Columbia. Our holding tanks are engineered for sites where conventional septic systems aren't practical, providing a dependable single-compartment solution for sewage storage until it's pumped and hauled to a municipal disposal or wastewater treatment plant.

Every Tanks-A-Lot holding tank is built to meet the Alberta Private Sewage System Standard of Practice and complies with the latest Canadian Standards Association B66-10 requirements. With models ranging from 700 to 3,400+ gallons, we offer flexible sizing options based on household needs, plumbing fixture load, and local sewage hauling capacity — with larger systems achievable through interconnected multi-tank configurations.

In addition to sewage holding tanks, Tanks-A-Lot manufactures a full line of precast concrete products, including cistern tanks for clean water storage, septic tanks, sewage treatment plants, sumps, and utility vaults — all designed for durability and long-term performance in demanding Alberta and BC climates.

Key features across our holding tank line include a raised-lip manhole for superior sealing, a flexible rubber inlet to reduce line failures, cold-seam one-piece construction on select models, and an industry-leading 20-year limited replacement warranty — giving property owners, installers, and municipalities confidence in every installation.

Whether you need a residential holding tank, a cistern tank for water storage, or infrastructure-grade solutions for a wastewater treatment plant project, Tanks-A-Lot delivers CSA-certified precast concrete products backed by decades of manufacturing expertise.
