Delta Case Studies

Extended Aeration Enviro-Aire Package Plant Meets Expanded Permit Parameters and Flows

Hattiesburg (MS) Laurel Regional Airport Authority had an undersized 20,000 GPD wastewater
treatment system servicing the airport and local business park. Treated effluent discharges to a
Pascagoula River Basin tributary. When the Authority applied for an updated permit for an increased
flow of 50,000 GPD, the State conducted a waste load allocation study and imposed more stringent
permit parameters including increasing BOD from 30 mg/L to 14 mg/L, 6.0 mg/L dissolved oxygen level and 2.0 mg/L total ammonia levels, and nutrient monitoring.

ECOPOD® Offers Simple Operation and Robust Treatment for Auto Camp Glamping Facility Wastewater Treatment System

A new AutoCamp glamping facility just outside the west entrance to Joshua Tree National Park in San Bernardino, California required a wastewater treatment system that could handle daily flows from the 55 Airstream campers estimated at 100 gallons per day (GPD) per Airstream. Located in a sensitive environment that included large, mature tree growth, the system also needed to provide minimum disruption to the landscape and visual impact to guests.

Delta Package Sewage Treatment Plant Replaces One in Service for More Than 35 Years at Louisiana Community Park

Pelican Park in Mandeville, Louisiana is a 550-acre community park with 32 athletic fields, two gyms, and a 46,000 square foot multipurpose community center. The community park also includes an 18-hole disc golf course and parking for more than 1,700 vehicles. Nearly 35 years ago, the community installed a 3,000 gallon per day Delta Package Sewage Treatment Plant to serve park operations at that time.

Improving Wastewater Quality for an Ecologically and Culturally Sensitive Community on the Coast of Hawaii

A coastal retreat community located on the shores of Hawaii was looking to remove large capacity cesspools that serviced their vacation lodging facilities. The goal was to replace them with a technology that provided improved water quality in order to protect beaches and waterfront enjoyed by approximately 500,000 recreational users annually. The technology had to be mindful of sensitive ecological constraints and stringent regulations while protecting and maintaining ancient Hawaiian burials and cultural resources.
