The Unistorm system employs low-head loss internal flow diffusers and flow distributors to reduce stormwater turbulence and improve flow distribution. This allows on-line operation to eliminate pollutant bypassing during high-intensity rainfall events. Its design allows it to help you meet the EPA goal of 80% TSS removal efficiency and 40% phosphorus removal. Shallow sump depth of 4-5 feet reduces excavation costs and facilitates pumpout. Unistorm systems are ideal for sites with limited space and/or difficult soil conditions.
For over 30 years, Gainey’s has been the leading manufacturer of custom Wastewater, Stormwater and Industrial precast concrete products throughout Louisiana and the Gulf Coast. Starting out as a residential septic tank installation company in 1981, it would soon grow to expand its portfolio to include new markets and various product lines. After being dealt a devastating blow in 1994 with the death of Richard Gainey, the founder, the Gainey family rallied together in order to keep his dream and the company alive. Through the hard work of company president, Greg Roache, and the Gainey’s employees, the company is alive and thriving, and constantly growing to accommodate the needs of an ever-changing industry.
