Key Benefits of FRP Mocoat Wastewater Tanks

Lightweight Design for Simple Transport and Installation

One of the standout features of our FRP septic tank in Washington is its lightweight construction. Compared to traditional materials like steel or precast concrete, fiberglass offers significant logistical advantages.

  • Faster delivery and handling: The reduced weight allows for easier loading, transportation, and unloading at job sites.
  • Minimal heavy equipment: Installation can often be done with smaller machinery, reducing setup costs.
  • Ideal for remote access: Lightweight tanks are particularly beneficial for installations in areas where large equipment access is limited, such as forested, mountainous, or rural regions.

This ease of transportation and installation translates into lower operational expenses and faster project timelines – two priorities for engineers and contractors alike.

Corrosion-Resistant and Leak-Proof Construction

Fiberglass-reinforced plastic (FRP) is inherently corrosion-resistant, making it an ideal material for storing human waste and wastewater. Unlike steel tanks that may rust over time or concrete tanks that can crack, FRP septic tanks maintain their structural integrity even after years of exposure to moisture, temperature changes, and chemical waste components.

  • No internal corrosion: Prevents breakdown from inside the tank due to waste chemical content.
  • No external rusting: Ensures environmental durability even in damp, acidic, or alkaline soils.
  • Leak-proof monolithic design: Each tank is moulded as a single seamless unit to eliminate weak points that could leak or crack.

This level of durability significantly reduces the risk of groundwater contamination and expensive system failures.

Certified to CSA Standard B66 for Wastewater Use

FRP Mocoat’s wastewater tanks are fully compliant with CSA Standard B66, the benchmark for septic tanks and wastewater treatment systems in Canada. This standard evaluates:

  • Tank strength and design
  • Watertight integrity
  • Material safety and compatibility with waste content

Our adherence to CSA standards provides added assurance for municipalities, contractors, and homeowners seeking reliable solutions that meet both local and federal requirements in Washington and beyond.

Engineered for Subsurface Pressure and Load

In most installations, septic tanks are buried underground, where they are subjected to the weight of the soil above and the pressure of water tables. FRP Mocoat’s tanks are specifically engineered to withstand up to 2 feet of overburden, meaning they can be safely buried without risk of deformation or collapse.

  • High strength-to-weight ratio: Despite their lightness, FRP tanks resist compression and structural fatigue.
  • Safe for high-traffic zones: Tanks can be installed beneath lightly loaded surfaces, such as parking areas or landscaping, without fear of compromise.

This built-in strength makes our fiberglass septic tanks in Washington suitable for a wide range of site conditions – from soft loam to compacted clay.

Cost-Efficient for Long-Term Wastewater Management

Initial cost savings are just one part of the value equation. The real return on investment comes from reduced long-term maintenance and replacement costs:

  • No rust or decay = fewer repairs over time.
  • Seamless, crack-resistant design = virtually zero leakage risk.
  • Long product lifespan = fewer replacements across decades of use.

For municipalities and industrial clients, this translates to lower lifecycle costs and greater system reliability. For homeowners and rural property developers, it means peace of mind and fewer unexpected expenses.

Versatile Applications Across Sectors

Our fiberglass tanks are highly versatile, making them suitable for:

  • Residential toilet systems
  • Off-grid or rural properties
  • Municipal wastewater management
  • Agricultural operations
  • Commercial facilities
  • Temporary construction sites
  • Seasonal recreational properties (cabins, RV parks, lodges)

Whatever your application, FRP Mocoat can help specify the right FRP septic tank in Washington to meet your operational and environmental requirements.
