Map the wastewater route
Identify the expected flow, grease management, holding or approved discharge point, pump-out responsibility and contingency if the normal route is unavailable.
Keep the soil and stormwater separate
Dishwashing wastewater may contain food residue, grease and cleaning chemistry. Do not assume open-ground or storm-drain discharge is acceptable.
Verify capacity and service
Set the holding and pump-out plan from projected flow, service frequency, site access and the requirements of the responsible authority.
