GTA performed a preliminary feasibility evaluation for on-site wastewater disposal via spray or drip irrigation systems for the proposed residential development property in Westtown Township, Pennsylvania. The site was proposed for up to 397 residential units and was estimated to have wastewater flows ranging from approximately 80,000 to 100,000 gallons per day (GPD). The evaluation consisted of test pit exploration, soil profile evaluation, infiltrometer testing, soil borings, hydraulic testing, water quality evaluation, and groundwater mounding analysis. The results of our evaluation indicated that onsite wastewater disposal at the site was feasible.
