Backflow into a public water system can pollute or contaminate the water in that system (i.e., backflow into a public water system can make the water in that system unusable or unsafe to drink), and each water supplier has a responsibility to provide water that is usable and safe to drink under all foreseeable circumstances. Furthermore, consumers generally have absolute faith that water delivered to them through a public water system is always safe to drink. For these reasons, each water supplier must take reasonable precautions to protect its public water system against backflow. 

A backflow preventer is a means or mechanism to prevent backflow. The basic means of preventing backflow is an air gap, which either eliminates a cross-connection or provides a barrier to backflow. The basic mechanism for preventing backflow is a mechanical backflow preventer, which provides a physical barrier to backflow. The principal types of mechanical backflow preventer permitted in the City of Brentwood are the reduced-pressure principle assembly and the double check valve assembly. A double check valve (DC) assembly is only permitted on Fire Lines, all others are to be protected by a reduced-pressure principle (RP) assembly only.

A cross-connection is any temporary or permanent connection between a public water system or consumer's potable (i.e., drinking) water system and any source or system containing non-potable water or other substances. An example is the piping between a public water system or consumer's potable water system and an auxiliary water system, cooling system, or irrigation system. 

A DC is a mechanical backflow preventer that consists of two independently acting, spring-loaded check valves. It includes shutoff valves at each end of the assembly and is equipped with test cocks. A DC is effective against backpressure backflow and backsiphonage but can only be used on fire line installations in the City of Brentwood.

An RP is a mechanical backflow preventer that consists of two independently acting, spring-loaded check valves with a hydraulically operating, mechanically independent, spring-loaded pressure differential relief valve between the check valves and below the first check valve. It includes shutoff valves at each end of the assembly and is equipped with test cocks. An RP is effective against backpressure backflow and backsiphonage and may be used to isolate health or non-health hazards.

Backpressure backflow is backflow caused by a downstream pressure that is greater than the upstream or supply pressure in a public water system or consumer's potable water system. Backpressure (i.e., downstream pressure that is greater than the potable water supply pressure) can result from an increase in downstream pressure, a reduction in the potable water supply pressure, or a combination of both. Increases in downstream pressure can be created by pumps, temperature increases in boilers, etc. Reductions in potable water supply pressure occur whenever the amount of water being used exceeds the amount of water being supplied, such as during water line flushing, fire fighting, or breaks in water mains. 

Backsiphonage is backflow caused by a negative pressure (i.e., a vacuum ~ or partial vacuum) in a Public water system or consumer's potable water system. The effect is similar to drinking water through a straw. Backsiphonage can occur when there is a stoppage of water supply due to nearby fire fighting, a break in a water main, etc.

Water suppliers usually do not have the capability to repeatedly inspect every consumer's premises for cross-connections and backflow protection. Alternatively, each water supplier should ensure that a proper backflow preventer is installed and maintained at the water service connection to each system or premises that poses a significant hazard to the public water system. Generally, this would include the water service connection to each dedicated fire protection system or irrigation piping system and the water service connection to each of the following types of premises:

1. premises with an auxiliary or reclaimed water system:
2. industrial, medical, laboratory, marine or other facilities where objectionable substances are handled in a way that could cause pollution or contamination of the public water system;
3. premises exempt from the State Plumbing Code and premises where an internal backflow preventer required under the State Plumbing Code is not properly installed or maintained;
4. classified or restricted facilities; and
5. tall buildings.

Your neighborhood is assigned a week for the brush service to come through and pick up your brush.

If your neighborhood is listed as the first week, that means that is is the first FULL week of that month. So if the month starts on a Tuesday, then your week isn't doesn't start until the following Monday.

1. Administrative review. To hear and decide appeals where it is alleged by the appellant that there is error in any order, requirement, permit, decision, determination or refusal made by the building inspector or other administrative official in the carrying out or enforcement of any provision of the zoning ordinance.
   
2. Special exceptions. To hear and decide applications for special exceptions upon which the board is specifically authorized to pass.
   
3. Variances. To hear and decide applications for variance from the terms of the zoning ordinance, but only where, by reason of exceptional narrowness, shallowness or shape of a specific piece of property which at the time of the adoption of the provisions of this chapter was a lot of record; or where by reason of exceptional topographic conditions or other extraordinary or exceptional situations or condition of a piece of property the strict application of the provisions of this chapter would result in exceptional practical difficulties to or exceptional and undue hardship upon the owner of such property, provided that such relief may be granted without detriment to the public good and the intent and purpose of this chapter. Financial disadvantage to the property owner is no proof of hardship within the purpose of zoning. In granting a variance the board may attach thereto such conditions regarding the location, character and other features of the proposed building, structure or use as it may deem advisable in furtherance of the purpose of this chapter. Before any variance is granted it shall be shown that circumstances are attached to the property which do not generally apply to other property in the neighborhood.

Land use patterns as reflected in current zoning are carefully set by the Board of Commissioners, and it is often difficult to alter property zoning unless you are developing an open space subdivision. Section 78-87 of the Brentwood Municipal Code details the procedures involved in the rezoning of property within the City. The Municipal Code can be viewed, on-line by clicking here.

Generally, it requires approximately 45 to 80 days to complete the re-zoning process. Of course this depends upon the timing and completeness of the application. Five public meetings are required. Those meetings include:

• First reading of the ordinance before the Board of Commissioners;
• A community meeting where neighbors adjacent to the subject property are invited to hear and discuss the particulars of the re-zoning application;
• Planning Commission review and recommendation of the proposed ordinance;
• Public Hearing for the ordinance before the Board of Commissioners; and,
• Second and Final reading of the ordinance before the Board of Commissioners.

A plan, detailing the proposal is submitted to the Planning Department, who will coordinate its review. All necessary agenda backup is prepared by staff. 

All documents accepted as security for subdivision improvements must be issued by a financial institution that has a "C" or better rating from the latest Kroll Bond Rating Agency, https://srs.krollbondratings.com/ (formally the LACE Quarterly Financial Institution Ratings).

The financial institution issuing the security must be a member of the State of Tennessee Bank Collateral Pool and have a branch within the State of Tennessee within a radius of 100 miles of the City of Brentwood. Performance Bonds cannot be accepted as security for required improvements.

Application fees are based upon the proposed acreage to be re-zoned. The fee schedule is also detailed as part of Section 78-987 of the Brentwood Municipal Code. The fee schedule is as follows:

• Less than 25 acres - $1,000.00;
• At least 25 acres but less than 50 acres - $2,000.00;
• At least 50 acres but less than 100 acres - $3,000.00;
• At least 100 acres but less than 200 acres - $4,000.00; and,
• 200 acres or greater - $5,000.00.

The Planning Commission was created under the provisions of Tennessee Code Annotated (T.C.A.) §§ 6-19-101 and 13-4-101.
