Our specialized excavation and sewer crews recently completed a septic project in Markham, IL, ensuring full safety and compliance with state environmental codes. Here is a look at what we did: Phase 1: Septic CCTV Camera Locating To precisely find the system, our crew accessed the line and performed an underground camera inspection (televising). This allowed us to successfully trace, locate, and access the exact position of the septic tank layout beneath the surface before beginning any excavation. Phase 2: Code-Compliant Septic Tank Abandonment When a septic system is no longer used, Illinois law requires a strict procedure to eliminate environmental and physical hazards. Following state codes precisely, our licensed crew: - Excavated and exposed the existing tank structure. - Completely pumped out all remaining wastewater and solids using a licensed disposal truck. - Crushed and cracked the tank floor and walls to guarantee it can no longer hold water. - Filled the remaining cavity with approved clean stone, sand, and soil, compacting it completely to prevent any future yard settlement. - Backfilled and restored the surface grading using onsite materials. Leaving an old, unused septic tank untouched can lead to sudden structural cave-ins and dangerous yard sinkholes. We ensure the job is done right, cleanly, and fully to code. Whether you need advanced camera locating or a safe, licensed system abandonment, Allied Water Services has the heavy equipment and expert crews for the job.
