FAQ

Septic / Design

If your property is not connected to a municipal sewer system (i.e., you don’t receive a sewer
bill or have a utility connection), you likely have or need a septic system. For older systems,
signs such as standing water, slow drainage, or sewage odors may indicate system failure. EMS
can evaluate your situation and guide you through the next steps.

To design a septic system that aligns with your development goals, EMS begins by conducting a
site visit to evaluate the soil conditions. Based on the results, we recommend locations for an
excavator to dig test pits. Once the test pits are prepared, the local agency (County or DEQ) will
inspect and evaluate them.


If the agency approves, we return to the site to stake out the required drain field area for your
system. This stake demonstrates to the County/DEQ that there is sufficient space available. Once
confirmed, we proceed with designing your system.


After the design is finalized, it is submitted to the local agency for review. If approved, they will
issue the necessary permit.

Placement is determined by soil and site conditions. EMS works closely with county officials to
ensure your septic system is installed in a compliant and optimal location.

Start by reviewing property records or permitting documents. If those aren’t available, our team
can assist by using electronic locating tools to pinpoint the system’s exact location.

We do not recommend using septic additives. Most household cleaners are safe if used as
directed. When in doubt, our team can advise you on septic-safe practices.

We do not recommend septic additives. Most household cleaners are fine if used as directed.

✅ OK: Human waste, laundry discharge, bathing water, and standard household cleaners (when
used as directed).
❌ Avoid: Oils, grease, wipes, non-biodegradable items, harsh chemicals, plastics, or rubber
materials. These can damage your system and lead to costly repairs.

Wetlands

You’ll need a wetland determination and delineation. EMS partners with certified specialists to
map and report wetlands, helping you navigate development requirements and comply with
regulations.

Look for signs such as soggy soil, persistent puddles, lush vegetation, and poor grass growth. If
you’re unsure, we offer professional evaluations to confirm.

Wetlands are areas of saturated soil that support unique ecosystems and are regulated to protect
water quality and wildlife habitats. EMS helps interpret how this may impact your property and
works within guidelines to ensure your system is installed in a compliant and optimal location.

Yes, but it requires mitigation and permitting. We guide you through the county’s requirements
and help determine if development is possible.

Wetlands often come with building restrictions and land-use limitations. EMS evaluates how
these constraints may impact your project and helps develop a clear path forward.

A delineation, conducted by qualified professionals, provides precise wetland boundaries. We
also utilize mapping tools to give you a complete view of the area.

Wetland determinations are made by state-licensed professionals, such as wetland scientists,
engineers, or the Department of State Lands. EMS coordinates with the appropriate agencies to
ensure a smooth and compliant process.

Maintenance

All septic systems require regular maintenance. If you’re unsure when yours was last serviced,
check public records or contact us directly. Signs like slow drainage or unpleasant odors may
indicate it’s time for a checkup.

Maintenance frequency depends on your household size and system type. Most systems benefit
from annual or semi-annual checkups, which EMS can help schedule and track for you.

During a maintenance visit, our certified team inspects your system, checks for signs of wear or
failure, and provides a detailed written report outlining its current condition and any future
service needs.

Regular maintenance ensures your system functions as designed and keeps you in compliance
with local regulations. It also helps prevent costly repairs and environmental damage.
