RFQ Input Checklist Builder

Fill in the site inputs an application engineer needs, and the builder lists what is still missing, flags the checks that change the design, and writes a brief you can paste into the enquiry.

What the flags mean

Cover under 1 m beneath a trafficked surface is flagged for analysis by the engineer of record. An infiltration layout with less than 0.61 m (2 ft) between the tank base and the seasonal high water table is flagged because that separation is the EPA siting reference for infiltration, and lined attenuation is the usual alternative. Any infiltration layout is flagged to contact the permitting authority and confirm applicable Class V inventory and authorization requirements, and US federally assisted funding is flagged to screen applicable Buy America origin requirements and waivers. Missing pretreatment is flagged because modules provide no water quality treatment.

The brief is a summary of your own inputs for the enquiry form; it is not a design and does not replace the drainage engineer’s calculations.
