DFI has extensive experience with the design and processing of septic systems and septic site plan designs. DFI handles all aspects of the environmental health process regarding septic designs and well placement including applications for percolation tests, coordination of septic contractors for the testing, survey stakeout of percolation tests, securing Health Department recommendations for the house size and preparing the septic site plan based upon the Health Department recommendations. DFI is experienced in designing septic site plans using trenches, drywells, pressure dose beds and mound systems to work with whatever soil types your approved percolation tests indicate. If there are water wells on-site or on adjacent sites, DFI will research Health Department records and field locate wells that would impact the septic design and then prepare a plan to coincide with those identified well locations.
DFI also designs and generates construction plans for commercial septic plans. These plans are based upon calculated flow rates for the commercial use and include tank sizing, drain field or drywell sizing and preparation of the profiles for the proposed system.
DFI maintains an excellent rapport with the various review agencies and possesses a clear understanding of what is required to secure septic site plan approvals. We also integrate the design with the grading permit or commercial site development plan to insure that the septic system and well design will not be in conflict with the other site features such as stormwater management.
Springer Lane is a single family home located in Lothian, Maryland. The project is part of an earlier subdivision, where the individual lots were then sold off and developed individually, this lot is situated on 1.57 acres of land. This site was part of an old farm in South County. Stormwater management for the site was designed utilizing the environmental site design criteria based upon the new state and county stormwater management criteria. Stormwater management was addressed by utilizing the nonstructural credits to the maximum extent then by utilizing Landscape Infiltration Devices. In addition to creating an environmentally friendly site layout the project also required design and approval of plans for a private septic system and private well. Because this lot was part of an earlier subdivision DFI was careful to ensure that the development of this lot was in conformance with the earlier approved Final Development plans prepared for the subdivision to create a seamless permitting process.
