Curtain drains can be no closer than 10' uphill or 30' downhill from the drainfield. 5. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 6. Operation & Maintenance is required by the state of Washington and the county for all septic systems. 7. Please contact B-Line Construction for periodic Operation & Maintenance service of your system. 8.
