In the case of SI units, the following is correct: 1 square foot equals 0.0929 m2, 1 gallon per day equals 3.785 liters per day Notes:1 Sizing sewage disposal systems in accordance with predicted waste and sewage flow rates must be performed as follows: a. waste/sewage flow rates of up to 1500 gallons per day (5678 L/day) are possible. Waste / sewage flow exceeding 1500 gallons per day (5678 L/day) Equals septic tank size (b) Flow 1.5 = septic tank size Flow 0.75 times 1125 equals the size of a septic tank (c) The secondary system must be designed to handle the entire flow rate per 24 hours.

Because of the large number of variables that must be taken into consideration, it is not possible to define absolute figures for waste / sewage flow rates for all circumstances.

Household Sewage Systems

Geauga Public Health’s Environmental Health Division is responsible for regulating all home sewage treatment systems (HSTS) in accordance with Chapter 3701-29 of the Ohio Administrative Code and any other resolutions made by the department. This covers all single-family, two-family, and three-family residential residences supplied by an individual home sewage treatment system. Approximately 70% of the estimated 32,350 dwelling units in Geauga County rely on domestic sewage systems to dispose of waste water, according to county estimates.

As a supplement to the Ohio Administrative Code (OAC) Chapter 3701-29 Household Sewage Treatment Systems, the Geauga County Board of Health has enacted the following regional codes:

  • 3701-29 Supplements to Section 6
  • 3701-29-24 Inclement Weather Occupancy Permit
  • 3701-29-25 For Sale of Property Evaluation
  • 3701-29-29 Supplements to Section 6
  • 3701-29- 3701-29-26 Land Application of Septage Rules
  • 3701-29-27 Rules for Land Application of Septage

System operators and maintenance personnel are employed by the Geauga County Department of Water Resources or the municipality in which the system is located. Sanitary sewage systems that transport sewage to a central wastewater treatment plant fall under the jurisdiction of the Ohio Environmental Protection Agency. Geauga Public Health provides the following services for household sewage treatment systems: site evaluation for new systems, permits for new systems, permits to alter existing systems, investigation of complaints regarding malfunctioning systems, and enforcement measures for failure to comply with these regulations, which include hearings before the Geauga County Board of Health and referral to the Geauga County Prosecutors Office for placement on the docket of the Common Pleas Court.

Septic Systems Overview

Over one-fifth of all American houses rely on individual sites or small community cluster systems (septic systems) to treat their wastewater, according to the Environmental Protection Agency. Modest-scale wastewater treatment and disposal systems are used to treat and dispose of relatively small quantities of wastewater, which are often generated by households and businesses in suburban and rural areas that are not served by a major public sewage system. Wastewater from residential plumbing fixtures (toilet, shower, and laundry) is treated using both natural and technical processes in septic systems, with the process often starting with sediments settling in the tank and concluding with wastewater treatment in the soil via a drainfield.

Septic systems are also referred to as:

  • On-site wastewater treatment systems, decentralized wastewater treatment systems, cluster systems, package plants, on-lot wastewater treatment systems, individual sewage disposal systems, and private sewage systems are all options.
See also:  How To Inspect My Septic Tank? (Question)

The many methods of decentralized wastewater treatment, when correctly implemented, may safeguard public health, preserve important water resources, and help a community retain its economic vibrancy while also reducing costs. The use of these technologies for wastewater treatment, particularly in less densely inhabited areas, is both cost-effective and long-term.

  • Highlights from the Decentralized Wastewater Management Program’s Annual Report for 2013

What are the benefits of using septic systems to manage wastewater from small communities?

  • Benefits to the general public’s health Decentralized systems, when used properly, limit the danger of disease transmission and human exposure to pathogens, which can occur as a result of contaminated drinking water, surface water, or shellfish beds. -Wastewater treatment reduces contaminants from surface water, recharges groundwater, and refills aquifers, among other advantages. Advantages in terms of economics – Decentralized wastewater systems assist communities in reducing substantial infrastructure and energy expenses associated with collecting and treating wastewater.

Are septic systems more prevalent in some areas of the country?

According to the United States Census Bureau, the distribution and density of septic systems varies greatly by area and state, with a high of around 55 percent in Vermont and a low of approximately 10 percent in California, respectively.

  • The New England states have the greatest proportion of households served by septic systems in the country, according to the EPA. Individual systems serve around one-half of all residences in New Hampshire and Maine, according to state statistics. Homes in the southeastern states rely on these systems in greater numbers than one-third of the time. This includes roughly 48 percent of homes in North Carolina and over 40 percent in both Kentucky and South Carolina. Septic systems provide service to more than 60 million people in the United States. The treatment of approximately one-third of all new development is provided by septic or other decentralized treatment systems.

Do septic systems cause health or water quality problems?

In the right circumstances, septic systems may provide excellent wastewater treatment when they are planned, developed, installed, managed, and maintained appropriately. Systems that are sited at densities that exceed the treatment capability of area soils, as well as systems that are poorly planned, installed, operated, or maintained, can, on the other hand, cause issues. The pollution of surface waterways and ground water with disease-causing microorganisms and nitrates is one of the most significant known concerns in recent history.

Disease infections are contaminating critical shellfish beds and swimming beaches in several coastal locations, which is a source of concern.

How are septic systems regulated?

Construction and operation licenses for septic systems are issued by municipal health departments in most states, in accordance with state laws governing public health protection and the abatement of public nuisances, respectively. Because of the potential consequences of nitrogen and phosphorus runoff, several states have included measures for water resource preservation in their septic system rules. In most regulatory programs, the local permitting agency conducts a site evaluation to establish if the soils can offer enough treatment for the pollutants being treated.

When conventional soil-based systems are not feasible, several governments allow for the use of alternate methods.

On-site wastewater treatment systems are subject to regulation.

  • Individual on-site systems are governed by state, tribal, and municipal laws
  • However, there is no federal regulation. Large capacity septic systems are controlled by the Environmental Protection Agency’s Safe Drinking Water Act Underground Injection Well program, which sets forth the standards for large capacity septic systems. Systems that discharge pollutants into surface waterways are controlled by the Environmental Protection Agency’s National Pollutant Discharge Elimination System program, which is part of the Clean Water Act. Septic tank disposal and home septage are governed by the Environmental Protection Agency’s sewage sludge rule (PDF) (1 page, 107 kb,About PDF), which is available online (40 CFR Part 503).
  • EPA Part 503 Regulation: A Guide to Biosolids Risk Assessment covers the risk assessment approach that served as the foundation for the biosolids rule.

What terms are commonly used when talking about Septic Systems?

The Environmental Protection Agency’s Glossary of Septic System Terminology comprises words typically used in the wastewater treatment sector, as well as meanings for each phrase.
