Plot Plans

Septic System Repair or Replacement: MJS Engineering & Land Surveying, PC is experienced in assisting clients with septic system problems associated with failure or expansions to their systems.

A septic system is a means by which sewer effluent, after being treated in a septic tank, is discharged into a series of absorption trenches for absorption into the soil. Older systems (20 years or older) were generally not designed utilizing the NYS Health Department criteria. These older homes were sometimes built as summer bungalows and then turned into year-round homes. In addition to the property not being large enough to handle a more modern system, there are generally many other constraints that need to be considered in order to replace the system with one that meets NYS Health Department regulations.

MJS works with local health departments in order to rehabilitate and reconstruct these systems to try to meet current regulations. We work closely with the various town or village building departments to replace a system.

The first step is to conduct a site observation and review background information from the various municipalities or homeowners. We will conduct a site observation to review the problems associated with a septic system reconstruction. We then conduct percolation testing to verify the absorptive capacity of the soil in the location where the septic system would be located.


Site Plans

MJS Engineering & Land Surveying, PC has provided its clients with Site Plan, land use and construction documents for a host of projects both locally, nationally and internationally.

As part of the Site Plan process, this office assists its clients in site selection by conducting background checks and site visits to determine their needs for a particular location and use. We will prepare a set of construction documents for the construction an layout of these facilities.

An important consideration in construction document preparation is the experience that a firm has as it relates to detailing the components for the Site Plan. Because of the expertise that this firm has, clients have indicated that the document set was thorough, saving both time and money during the construction process.
