Luxury Homes and Septic Systems:
For a luxury home average sewage flow per occupant is often higher than for an average home. Luxury
homes often include the following:
• Larger overall floor area with larger rooms than an average home.
• High quality, high cost materials than average.
• More water use appliances than an average home.
• Domestic service workers.
• Large parties and frequent guest use.
Average flow per occupant for luxury homes is reported to be approximately twice that for normal homes,
and sewage flow typically increases with increasing cost of homes (Laak 1986; Geyer and Lentz 1966).
