Seattleites are Singing in the Rain

Transporting Water TankIt’s not just Seattleites that are having rainwater collection systems installed before the end of this long and extensive rainy season. RainBank has been traveling up and down the I-5 corridor from Portland Oregon to Bellingham Washington this winter. Interest in residential rainwater harvesting is seeing an all time high in the region. Water quality concerns, last year’s drought conditions, and the green movement all have consumers looking for alternate water supplies for potable and non potable demands.

Customers are reporting that storage volumes in their water tanks are remaining full, and with expected rainfall amounts to stay high through Spring, Seattleites and others are “singing in the rain”. Commercial interest in rainwater collection also remains high. Many projects, large and small, are choosing to use rainwater for irrigation and toilet flushing and recognizing cost savings. RainBank Rainwater Systems has met this demand by becoming Pinnacle and Contain Water Tank’s Northwest Master Dealer offering dealerships throughout the region.

RainBank Rainwater Systems is the ARCSA Northwest regional representative and offers workshops for education and promotion of rainwater collection. The mission of the American Rainwater Catchment Systems Association (ARCSA) is to “promote sustainable rainwater harvesting practices to help solve potable. non potable, stormwater and energy challenges throughout the world.”

Standards for Rainwater Collection

water-321524_640The Rainwater collection industry is rapidly becoming more accepted, consumers are becoming more aware of water shortages, quality of water, and increasing costs of operations of a centralized water system are being passed onto the customer. Many are turning to a supplementary source of water, whether from a simple rain barrel, for small irrigation needs or a large-scale sustainable system for whole-house demands. The industry itself is changing and becoming more complex. States and counties throughout the US are witnessing such a rapid growth in interest of rainwater collection, many are struggling with regulations and standards to ensure public safety. In addition, increased demand is beginning to outpace the supply of available, qualified RWC system designers and installers. Without proper regulations standards, improper designs and installations by unqualified persons can lead to underperforming or even dangerous systems.

Without quality information and education, governmental intervention can lead to laws that do nothing to protect the consumer and the industry itself. Therefore the American Rainwater Catchment Systems Association (ARCSA) is the leader in education and information about RWC. The American Society of Plumbing Engineers, (ASPE) develops plumbing and design standards through a consensus of a standards development process in accordance with the American National Standards Institute, (ANSI). The Plumbing Engineering Standards are designed to provide accurate and authoritative information for design and specification of plumbing systems.

ARCSA/ASPE/ANSI63-2013: Rainwater Catchment Systems Standard was approved by the American National Standards Institute on Nov. 14, 2013 and was developed by a joint effort and sponsorship support from the International Association of Plumbing and Mechanical Officials (IAPMO) and the National Science Foundation (NSF) International. The purpose of this standard is to assist engineers, designers, plumbers, builders/developers, local government, and end users in safely implementing a rainwater collection system. This standard is intended for application to new rainwater catchment installations, as well as alterations, maintenance, and repairs to existing systems.

ARCSA and RainBank Rainwater Systems are committed to education and the advancement of rainwater collection. RainBank’s president Ken Blair is ARCSA’s North West Regional Representative.

Potable Rainwater System in Skagit County

skagit tulipsSkagit County Health and Planning Departments allowed construction of a rainwater collection system as the primary source of water for construction of a new family residence. As many as 5,000 property owners may now have a solution to a well moratorium that has been imposed in the river basins because of instream flow rules.

Chris Webb of Herrera Environmental designed the 10,000 gallon potable system to supply the residence with enough water to support a family of four, year round without another water source. Filtration, along with ultra violet disinfection, will treat the rainwater to a quality standard which surpasses groundwater and most well water. Water samples will be taken and sent to a lab for testing with results shared with the Skagit County Department of Health.

RainBank will work with Skagit County to help set standards for rooftop collection for potable use, with the hopes that the practice will allow property owners in the affected river basins to have a viable source of clean, safe drinking water and be able to develop their properties. Other counties in the Puget Sound region have recognized rainwater collection as a supplementary source to wells, city water, and community water sources and sole source use in conditions that a traditional source is not available.

RainBank Rainwater Systems, with 15 years experience in designing and construction of sustainable, potable rainwater collection systems is committed to educating the public and county officials in the benefits of rainwater collection.
