Pride Plumbing came out and 1) used an excavator to trench a ditch from the building to a septic tank underneath an asphalt parking lot; 2) installed a new 4-inch PVC sewer drain line (connecting it to the main drain line under the building) along with tracer wire, proper cleanouts and fittings per code; 3) sealed the septic tank penetration with concrete; and 4) backfilled, tamped, and spread grass seed and straw after the work had been completed.
