Less Algae Equates to Better Water Quality
By blocking sunlight within its tanks with GTI’s structurally supported covers, the water treatment plant has effectively reduced algae growth. The decision to install the covers has also reduced chemical usage and minimized the formation of disinfectant by-products (DBPs).

Sunlight-Blocking Covers Control Algae, Reduce Operational Costs at California Utility
To address algae growth, the Santa Clara Valley Water District chose to cover its tube settlers with GTI's strucuturally supported covers. That choice allowed its treatment plant to successfully reduce algae and cut back chlorine feed. The plant is expected to recover the cost of the covers and save an additional $500,000 over the lifetime of the covers.

Algae Control
Excessive algae growth can throw even the best water treatment processes out of balance. Algae can clog intake screens, fluctuate pH levels, increase chlorine demand, and negatively affect the taste and smell of water.
By blocking sunlight within water treatment tanks, you can stop algae growth, reduce chemical usage, and minimize the formation of disinfectant by-products (DBPs). Temperature is better controlled and maintenance associated with algae cleaning is simplified. The results? Better water treatment and lower operating costs.
Several cover styles can be used, depending on the application, including structurally supported covers, suspended covers, modular covers, and gas collection covers.
