Napa County Municipal Code Ch. 13.20 Connection to Approved System

Every building in which plumbing fixtures are installed, and every parcel having drainage piping thereon shall have a connection to an approved sewage disposal system (CPC § 713.1, modified).

Exception 2: Hold and haul systems accepting non-domestic sewage within a public sewer boundary may be permitted provided such system complies with the requirements of this code and the public sewer agency provides a written waiver for such system to the administrative authority.

(Ord. No. 1374, § 28, 9-11-2012)

When no public or private sewer is available in any thoroughfare or right-of-way abutting such lot or parcel, drainage piping from any building or works shall be connected to an approved individual sewage disposal system or private sewage disposal system (CPC § 713.2; modified).

(Ord. 1109 § 1 (part), 1996: prior code § 5501)

Where a lot or parcel is presently within the district of a sewage entity but not yet served by such entity, no permit shall be issued for the installation, alteration or repair of any individual sewage disposal system or part thereof unless the sewage entity waives the connection requirements (CPC § 713.5, modified).

(Ord. 1109 § 1 (part), 1996: prior code § 5504)

A public sewer shall be considered unavailable when:

A. Such sewer is located more than two hundred feet from the nearest building proposed on any lot or parcel; or

B. The lot or parcel is located outside the sphere of influence of the sewer entity; or

C. The connection will require the installation of a pump station which is not maintained by the sewer entity; or

D. The sewer is already over capacity (CPC § 713.4, modified).

(Ord. 1109 § 1 (part), 1996: Ord. 738 § 2, 1983: prior code § 5503)

A. If the administrative authority determines that public health is endangered, or potentially endangered, by the failure of a significant number of individual or private sewage disposal systems located within the district of a sewage entity, or any part thereof, and a public sewer is available:

1. No new individual or private sewage disposal systems may be installed in the district or part thereof; and

2. All individual or private sewage disposal systems in the district or part thereof shall be abandoned within ninety days; and

3. All developed parcels in the district shall be connected to the public sewer within ninety days.

(Ord. 1109 § 1 (part), 1996: Ord. 738 § 3, 1983: prior code § 5507)

(Ord. No. 1374, § 29, 9-11-2012)

Within the limits prescribed by Section 13.20.040 of this chapter, the rearrangement or subdivision into small parcels of a lot which abuts and is served by a public or private sewer, shall not be deemed cause to permit the construction of an individual sewage disposal system, and all plumbing or drainage systems on any such smaller parcel or parcels shall connect to the public or private sewer (CPC § 713.3).

(Ord. 1109 § 1 (part), 1996: prior code § 5502)

A. Nothing contained in this division shall be deemed a requirement to alter, change, reconstruct, remove or demolish any drainage system or part thereof if such system or work was installed in accordance with any applicable law in effect at that time. However, if any drainage system or other work regulated by this division is in the judgment of the administrative authority a nuisance, or is dangerous, unsafe, unsanitary or a menace to life, health or property, then such plumbing or drainage system or part thereof or work regulated by this division shall be made to comply with the requirements of this division.

B. Applicants proposing new residential construction activities on existing structures that result in, or may result in, additional wastewater flows, including, but not limited to, the addition of a potential bedroom must comply with the requirements of this division. Remodels, additions, alterations or expansions of residences that increase and/or alter the square footage but do not result in additional wastewater flows are required to have the sewage disposal system inspected by a licensed sewage contractor for certification that the existing system is in good working order and an expansion area complying with the requirements of this division is established, if one does not already exist. An expansion area can only be established by the performance of a site evaluation complying with the requirements in this division and approved by the administrative authority. Minor construction projects that will not result in additional wastewater flows, or impact the primary or potential expansion sewage disposal system areas, may have the inspection and/or expansion area requirements waived at the discretion of the administrative authority.

C. If it is impossible to maintain minimum distances between features on the same lot or parcel as required by Table 13.28.040, repairs may be made to systems where, in the opinion of the administrative authority, such repairs will not create a nuisance, or dangerous, unsafe or unsanitary conditions. In no event shall any repairs to a sewage disposal system, or part thereof, be allowed where the repaired system, or part thereof, is at a distance closer to a listed feature in Table 13.28.040 than currently exists on the same lot or parcel or adjoining lot or parcel. However, in no case shall the setback between wells and potential sources of sewage contamination be less than fifty feet.

D. Where the administrative authority has determined that the existing drainage system or part thereof, or work regulated by this division is a nuisance, or is dangerous, unsafe, or unsanitary, then the administrative authority shall notify the owner thereof. The owner shall be required to bring such system into compliance with this division within thirty days (CPC Appendix Chapter 1, § 101.5, modified).

(Ord. No. 1337, § 12, 5-5-2010; Ord. 1109 § 1 (part), 1996: prior code § 5600)

A. It is unlawful for any person to deposit, by any means whatsoever, any ashes, cinders, solids, rags, inflammable, poisonous or explosive liquids or gases, into any plumbing fixture, floor drain, interceptor, sump, receptacle or device which is connected to any drainage system, public sewer, private sewer, sewage disposal system or septic tank (CPC § 714.1, modified).
