Town of Old Saybrook Wastewater Upgrade Program Standards ("Standards")

Effective Date: September 2, 2009


§1. Definitions

For the purposes of the Old Saybrook Decentralized Wastewater Management District (and specifically not under the State of Connecticut Public Health Code or Connecticut Department of Environmental Protection regulations), the following shall have the definitions as provided herein. Any capitalized term not herein defined shall have the meaning as provided in the WWMD) Ordinance.

Alternative Sewage Treatment System: A sewage treatment system serving one or more buildings that utilizes a method of treatment other than a Subsurface Sewage Disposal System and that involves a discharge to the ground waters of the state.

AT [advanced treatment] System: A type of Alternative Sewage Treatment System that provides reduction of effluent nitrogen concentration by a) a minimum of fifty percent (50%), exclusive of the leaching system component, or b) by a minimum of sixty percent (60%) if measured within twenty four (24) inches of the bottom of the leaching system. An AT System may include both a biological or mechanical treatment system component and a leaching system component. Only those biological or mechanical treatment systems approved by the WPCA and the DEP for use in AT Systems in the WWMD shall be considered to meet the reqirements of these Standards. Such biological or mechanical treatment system approvals shall be based upon, among other things, the manufacturer's certification and/or acceptable (to the WPCA and DEP) test results showing a minimum of fifty percent (50%) or sixty percent (60%), as applicable reduction in total effluent nitrogen concentration.

AT Lot - (i) any Non-Water Proximity Lot that requires the installation of an AT System, as provided in Section 8C(3) of the WWMD Ordinance, and (ii) any Water Proximity Lot.

AT System Operator - A person who is qualified to provide operations and maintenance services for the specific AT Systems selected for use in the WWMD. An AT System Operator is required to meet training and experience requirements set forth by the WPCA and the DEP Delegation.

AT System Installer - A person who is qualified to install the AT Systems selected for use in the WWMD. AT System Installers are required to meet training and experience requirements set forth by the WPCA and the DEP Delegation.

Bedroom: An area within a residential building which is or has the potential to be utilized as a sleeping area on a consistent basis. In order to be deemed a bedroom the area must meet all of the following standards:
1. Be a habitable or planned habitable space per Building Code requirements. Planned habitable spaces would include those areas which contain the appropriate "roughed- in" mechanicals, such as heating ducts, hot water lines or plumbing waste lines, etc., but are not currently "finished" to meet Building Code requirements for habitable space.

2. Provide privacy to the occupants. Large (minimum 5 feet width) openings or archways can be utilized to eliminate room privacy.

3. Full bathroom facilities (containing a bathtub and/or shower) are conveniently located to the bedroom served. Convenience in this case means on the same floor as the bedroom or directly accessed from a stairway.

4. Entry is from a common area, not through a room already deemed a bedroom.
Cesspool: A buried structure which receives sewage from a House Sewer/Building Sewer for the purpose of collecting solids and discharging liquid to the surrounding soil.

Change in Use: Any structural, mechanical or physical change to a building which allows the occupancy to increase; or any change in the activities within a building to expand or alter such building or the use thereof such that, when the building is fully utilized, the design flow or required effective leaching area of the Subsurface Sewage Disposal System will increase. A Change in Use also includes any internal change to a building which, while not increasing the square footage of habitable space, changes the configuration in such a way that there is an increase in design flow of the Subsurface Sewage Disposal System.

§2. Applicability
These Standards apply to the management of Wastewater in the WWMD as follows:

A. Developed Lots
Every Developed Lot shall comply with these Standards as specified below:
i. For any Developed Lot that cannot provide a minimum vertical separating distance to groundwater of twenty-four (24) inches: (1) fill systems to achieve the twenty-four (24) inch minimum vertical separating distance to groundwater shall he provided, or (ii) other approved technology or system shall be installed. With the exception of AT Lots, and only with respect to minimum vertical separating distance to groundwater, if an existing Subsurface Sewage Disposal System on a Developed Lot has been constructed, repaired or upgraded to the standards of the Public Health Code since and as in effect on January 1, 2000, then such system may remain so long as it otherwise complies with the Public Health Code.

ii. If the Public Health Code is amended to increase the minimum vertical separating distance above twenty-four (24) inches, these Standards shall utilize such increased minimum vertical separating distance for any Developed Lot not yet repaired to meet the Upgrade Program standards. Any Developed Lot repaired to the twenty-four (24) inch mininmm vertical separating distance prior to such a change in the Public Health Code shall not be required to meet the increased minimum vertical separating distance to groundwater until and unless a future Change in Use or repair is made. Any new Leaching System on a Developed Lot shall be installed in accordance with the requirements of the Public Health Code, but in no case shall the minimum vertical separating distance be less than twenty-four (24) inches.

iii. If an existing Sewerage System upgrade is required pursuant to the WWMD Ordinance and these Standards such that the effective leaching area must be increased by fifty percent (50%) or more, then the minimum vertical separating distance to groundwater shall be twenty- four (24) inches.
B. Vacant Lots
Proposed Construction on a Vacant Lot shall not occur unless the Property Owner demonstrates that a proposed SSDS complies with the requirements of the current Public Health Code including but not limited to providing a one hundred percent (100%) reserve area for a Leaching System, these Standards, and in addition, no proposed development of such Vacant Lot shall result in a density of greater Than one Bedroom per 0.11 acres. Vacant Lots that are AT Lots shall also comply with the standards applicable to such lots as provided herein and in the WWMD Ordinance.
C. Changes in Use
No Change in Use shall occur unless the Property Owner demonstrates to the satisfaction of the Director of Health a Subsurface Sewage Disposal System could be installed that satisfies all requirements of the Public Health Code and these Standards, except for the one hundred percent (100%) reserve area as provided in the Public Health Code. In addition, any Change in Use on a Lot shall not result in a density of greater than one Bedroom per 0.11 acres.

§3. Upgrade Program Standards
