Septic System
Septic system designs are
prepared for both residential and commercial uses by several on staff,
licensed septic system designers. A septic design can be as simple as one
based on traditional concepts, or one as complicated as including special
drainage design, solar orientation, tree preservation, and grading plans,
for a more completely designed home or building site. WMSC's staff is
licensed in both New Hampshire and Maine. Our design services are provided
on a flat fee basis excluding the costs for backhoe rental and state and
local application fees. While our design fees may sometimes be greater than
our competitors, the difference is generally more than made up in
reduction of the installation cost.

The design process typically starts with field work. A field crew topographically maps the proposed building site, leach field area, and other relevant site features which might impact the proposed design. In addition, a perc test and test pit are dug in an area believed to be suitable for a leach field based on an above ground site evaluation. The test pit is a hole dug by a backhoe to a depth from 5 to 10 feet depending on the soil conditions encountered. An evaluation of the soil profile in the pit will determine how high the proposed leach field will be above existing grade. A perc test is a small hole, dug with a spade, into which water is poured. The percolation rate of the water through the hole is timed and it is these results which determine the size of a proposed leach field.
This field data is reduced to a plan format and the final design is prepared. This along with the application get submitted to the state for approval. The duration of the approval process of a system can vary based on the complexity of the site and system. The state can require the submission of additional materials. Once an approval is received, WMSC provides its clients with two stamped copies of the design and information outlining the upkeep of the system once it is constructed.
Septic Design Projects:
-
Storyland - 1990-2001: Over the last 10 plus years, the children's amusement park located in Glen, NH known as Storyland has expanded significantly. Each year Storyland has made additions and/or improvements which have necessitated new sewage disposal system design. These systems we have designed have ranged from a small individual system for a specific building requiring disposal of about 300 GPD to an aggregate dry-well system located under the parking lot designed to handle 11,267 GPD. In total, we have designed systems to handle more than 35,400 GPD in the park.
-
Marriott Compound - 2001: Situated on the shores of Lake Winnipesaukee in Tuftonboro, NH, the Marriott family owns a family compound. Beginning in the fall of 2000 and continuing into the spring of 2001, we have been working with their architect to design a septic system which will handle the sewage flow for a total of 35 bedrooms, or 5,250 GPD. This system will service numerous buildings and will protect the lake by placing the leaching portion of the system on a remote location, more distant from the lake than might otherwise be the case if each building retained their own system on each waterfront lot.
-
"Wabanaki" & "The Beaches" Campgrounds - 2000: In order to comply with the State of New Hampshire D.E.S.'s deadline that all recreational campgrounds secure subdivision approval and septic system prior to September 5, 2000, we were involved in the design of septic systems for both of these campgrounds. Wabanaki Campground, located in Freedom, NH had a total flow of 6,800 GPD and serviced a total of 69 campsites. The Beaches Campground, located in Conway, NH had a total flow of 9,500 GPD and serviced a total of 108 campsites.
