For specific information on OWTS, county codes and requirements, see your local county health department or building department websites.


How long will it take to receive my On-Site Wastewater Treatment design or Geotechnical Engineering Study after the field work is completed?

This is depended on our work load, but typically 2 weeks.  We are typically busiest in the summer and fall where it can take up to 3-4 weeks.

What is the cost of an OWTS design by MET?

There is a design fee, in addition to a minimum of TWO site visits. Site visits are billed on a time and mileage basis. The initial site visit is required to map and classify soils; and a final inspection of the OWTS installation prior to backfilling the system. However, we also charge additional time for insufficient site plan preparation, or additional site visits if required. Please contact one of our offices for a current proposal.

For my On-Site Wastewater Treatment system design you requested that I supply a site map of my property.  I do not have one, what should I do?

Visit your county Assessor’s or Clerk and Recorder’s office and they should have a plat map of the property.  Most counties have a website where you can look up property information by address (Example: Chaffee County). Banks may also have a survey record of the property. If a survey has not been performed on the property we recommend having your property surveyed by a professional surveyor.  We can perform basic site mapping however it is not a survey. Additional site plan preparation is billed in addition to the design fee.

What information is required on the site map for my property?

Prior to a site evaluation we require a SCALED site plan containing property lines, north arrow; and proposed locations of the house, absorption field, and well. We also prefer staking of the house, sewer line exit, and well prior to a site evaluation for mapping purposes. As stated above, additional mapping due to insufficient information will increase both the cost and completion time of the OWTS design. Below is an example of an excellent site map including all the information we need:


Can I install the On-Site Wastewater Treatment system myself?

You should check with your county land use or building department to see if they require installers to be licensed.  When unlicensed contractors install our On-Site Wastewater Treatments system designs we charge an hourly rate for installation consultation.

What kind and how many holes need to be dug for the site evaluation?

Download the profile hole specifications here (pdf).

Does the design cost include the site and installation inspections?

No. Site inspections prior to and after installation are charged in addition to the design fee. Time and mileage are charged at rates listed on our proposal sheets.

How will you distribute my On-Site Wastewater Treatment System design?

We will send you the 11” x 17” wet stamp, an 11” x 17” copy, and the invoice in the mail.  By request this can also be picked up at the Salida office.  We will also email you a pdf copy of the wet stamp design for you distribute to installers for price quotes.
