Design of a Title 5 system begins by reviewing the details of the situation with the client. The discussion centers around the property location, whether it is a new or replacement system, the proposed use (residential, commercial, etc.), as well as, a general overview of the permitting process. Trinity Engineering performs an initial site reconnaissance, typically using aerial photography and GIS mapping systems, followed by site visit and proposal. Once the proposal is accepted, the field work can be scheduled.
In the field, the first step is a Site and Soil Evaluation which consists of conducting Deep Observation Holes (DOH) and Perc Tests to demonstrate that the site is suitable for a Title 5 system. The local Board of Health (BOH) must witness the Site and Soil Evaluation. A contractor is required to excavated the DOHs and Perc Test locations. Next, a site map is generated to show topography and key features for the design.
Once the design and permit application materials are completed they are forwarded to the client for their use. The client, or their contractor, must obtain a Disposal Construction Works Permit for the system installation prior commencing construction. During construction Trinity Engineering is available to respond to inquiries by the contractor.
A final inspection is required by both the BOH and Trinity Engineering. The final inspection is typically arranged by the contractor. Once the system meets with the approval of Trinity Engineering and the BOH, a Form 3, Certificate of Compliance (CoC) is signed by Trinity Engineering, as well as, the contractor and forwarded to the BOH. The BOH issues the final CoC. The BOH retains copies of the CoC, as should the client.
