Design Process Frequently Asked Questions
What about septic systems?
According to the Environmental Protection Agency, properly designed, installed and maintained on-site sewage disposal systems (OSDs) are a safe and environmentally friendly alternative to municipal wastewater treatment. Modern systems are designed based on maximum daily flow from the home, an objective evaluation of the soils and slopes in which it will be placed and the depth of a water table or other limiting layer below the system.
There are several types of OSDs; gravity systems, flood-dosed systems and mound systems are most common in our area. They are selected according to the criteria described above. OSD's can range in cost from $ 4000.00 to $ 15,000.00
Systems can last 20 to 30 years depending on how they are used and maintained. In general, water saving appliances (washer, softener, and dishwasher) will extend the life of the system as will keeping the use of garbage disposals to a minimum.
Though not all jurisdictions require it, we highly recommend setting aside a place for a future replacement system or reserve area. This area should be kept clear of buildings and driveways and should not be graded or filled.
Lack of soils and slopes suitable for a septic system can render a lot unusable,
even if it is acceptable in every other way. Take nothing for granted when
purchasing any lot using on-site sewage disposal. Just getting a soil boring is
not enough. It is important to know what type of system is required, how big it
is, where it will be placed and where the reserve area will be. You may
find that this will limit the location, the size and the design of the house
(ranch or two-story) and the possibility of building a pool or outbuilding. We
understand septic systems and can recommend professional assistance through our
established relationships with soil scientists, soils engineers and septic
designers.
