Major Companies Advancing Durable Plastic Water Storage Systems

Overview

The Global Plastic Water Storage Systems Market is projected to reach USD 12.4 billion by 2034, rising from USD 5.8 billion in 2024 and advancing at a 7.9% CAGR. In 2024, North America held a steady 36.30% share, supported by consistent residential and commercial demand. Plastic water storage systems—primarily made of polyethylene—remain vital for households, agriculture, industries, and emergency needs due to their durability, corrosion resistance, and suitability across diverse climates.

Market growth continues amid inconsistent water supply and rising construction activity in urban regions. Government-backed investments significantly accelerate adoption. The DANR’s USD 172 million funding for statewide environmental initiatives and USD 312 million awarded to communities for clean-water upgrades directly boost the installation of plastic tanks in public and underserved areas.

Similarly, the TDEC’s nearly USD 300 million in water-system improvements strengthen infrastructure for treatment, distribution, and storage, creating strong procurement opportunities for tank manufacturers.

Additional momentum comes from broader economic-development spending, with Gov. Reeves announcing over USD 100 million in upcoming development programs. Confidence in long-term industry expansion is further supported by JM Financial’s positive sector outlook, reinforcing sustained growth prospects for plastic-based water-storage solutions worldwide.
