Treatment with Drop Irrigation
Conventional In-Drain System Mound
Project Information
Date: February, 2002
Location: North Yarmouth, Maine
Facility: 4-Bedroom House
Design Flow: 360 Gallons per Day
Wastewater Type: Residential
The
photograph to the left shows a conventional in-drain disposal
area on a building site in North Yarmouth. The property
owner found the required mound to be unbearable and retained Aeration
Systems to install an OxyPro 1000 Wastewater Treatment Unit with
a sub-surface drip irrigation disposal area to solve this issue.
Drip Irrigation Lines Ready for Burial
The
combination of advanced treatment and subsurface drip irrigation
was a newly accepted technology in Maine and its usefulness and
versatility made it the perfect solution for this difficult site.
The design flexibility inherent in drip irrigation allowed the system
designer to use every available square foot of space, even though
the suitable area was triangular in shape. The ability of
the drip line to compensate for pressure differences also meant
that the system could be placed in an area with compound slopes,
thereby eliminating hundreds of yards of fill. The installed
cost of this system competes directly with conventional systems,
and site disturbances are greatly reduced. On top of it all,
this great house will have a beautiful lawn to match.
