With Complex Permitting, Choose the Right System Designer / Installer

At the beginning stages of planning a rainwater system, be sure to choose a system designer / installer who will work with you to design and build the most effective and efficient system for your needs. You especially want a company that knows how to navigate the complex permitting process.

Here is some information we originally published last year, which, if you are new to our blog, can be helpful as you plan your own system.

Skagit County Water Source

RainBank Rainwater Systems has broken through the barriers that have restricted rainwater collection as an approved water source for single family residences in Skagit County.

With the instream flow rules,  many property owners in the Skagit River Basin were unable to develop their properties. WA State Department of Ecology encouraged Skagit County to adopt the practice as a solution that would benefit the river and salmon habitat, while providing a viable water source. Limited permitting for the affected areas was considered as recently as 2015.

A group of residents from Guemas Island petitioned the county to accept rainwater for potable use for homes that were experiencing salt water intrusion in their wells. RainBank Rainwater Systems, along Tim Pope, ARCSA educator and past president, met with Skagit County in January 2017 to encourage acceptance of potable rainwater collection as a viable alternative source, not only in the instream flow rules affected areas but to those who are experiencing other hardships regarding potable water.

RainBank Rainwater Systems is pleased with the recent design approvals from Skagit County for potable residential RWC systems outside the instream flow rules, allowing for more property owners in Skagit County. We look forward to assisting Skagit County residents with their dreams of developing or purchasing properties with limited water resources.

Is Sole Source Use of Rainwater Collection Legal in King County?

lake-176942_640There has been a great deal of inquiry about sole source use of rainwater collection in King County, causing confusion for the public – as well as for King County public officials. RainBank is currently consulting on four different projects, assisting clients with navigating the system.

A change in Department of Public Health Policy, which is the authority on single source rainwater collection, has been transferred back to the Onsite Sewage System Authority (OSS) of King County Public Health.

There is a section of Title 13 that refers to rainwater collection for single source usage. This authority has jurisdiction over sole source use; any other permitting approval for supplementary source is to be approved by King County Public Health Department’s senior plumbing inspectors. There are plumbing codes that must be met with regard to installation and permitting from KCH plumbing division for any RWC system that is potable or non potable, that is connected to household plumbing.

Below is the section of Title 13 dated November 20, 2013, which refers to sole source usage

D. A rainwater catchment system that serves as the only source of drinking water for a single family residence and that complies with each of the following conditions:

1. The health officer finds that requiring connection of the plumbing system to an approved public water source or to an approved private well would cause undue hardship.

2. Application for a rainwater catchment system source approval shall be submitted for review on forms provided by the health officer. The applicant shall pay to the health officer the rainwater catchment system review fee as specified in the fee schedule, payable after completion of the application review.

3. Application for a rainwater catchment system source approval shall be prepared by any one or more of the following:

a. A professional engineer authorized under a current, valid license to practice in Washington state;

b. An environmental health professional holding a current, valid registration from either the Washington State Environmental Health Association or the National Environmental Health Association;

c. A King County licensed water system designer holding a current, valid license to design water systems in King County; and

d. A rainwater system designer holding a current, valid accreditation from the American Rainwater Catchment System Association.

4. Rainwater catchment system source design shall conform to Part III of Chapter 16 of the Uniform Plumbing Code, 2009 edition, as amended, and shall include, at a minimum, the following information:

a. Estimated daily and weekly and annual demand;

b. Available catchment area and estimated annual rainwater capture;

c. Roofing materials used;

d. Storage capacity of and materials used in the construction of the rainwater catchment system; e. treatment specifications including filtrations and disinfection system specifications; and

f. Operation and maintenance requirements.

5. Composite or shake shingles or other materials determined by the health officer to present a risk of contamination may not be approved or used as roofing materials for a rainwater catchment system source.

6. Before using a rainwater catchment system source, the property owner shall file in the county recorder’s office a notice on title advising that the property is served by a rainwater catchment system and including the following information:

a. The estimated daily, weekly and annual water supply furnished by the rainwater catchment system;

b. That the water supply from the rainwater catchment system may be limited due to variations in rainfall or usage; and

c. That regular maintenance of the treatment system and components is required in order to minimize the risk of consuming contaminated water.
