Simplicity at it's best: Meet the humble nylon stocking, your rainwater's low-cost guardian.
Our island's lush landscape, with its abundance of trees and diverse flora, presents a unique challenge when collecting rainwater. Many residents wonder whether pre-filtering their catchment water is necessary. As we'll explore, the answer is a resounding "yes." Let's delve into why pre-filtering your catchment water is so important and how something as simple as a nylon stocking can make a significant difference.
The Big Island's Unique Challenge
Hawaii's Big Island is known for its breathtaking natural beauty, from lush rainforests to rugged lava fields. However, this diverse ecosystem also means that rainwater collected from rooftops may contain considerable debris. The canopy of leaves, branches, and bird dropping can accumulate on rooftops, creating a potential challenge for rainwater harvesters.
Why Pre-Filtering Matters
Preserving Water Quality: When rainwater flows off your roof, it carries leaves, dry grasses, and other debris with it. The debris can end up in your gutter system, eventually entering your catchment tank. Without pre-filtering, the collected water may contain contaminants that affect its quality. Pre-filtering ensures that your water is cleaner and safer for whole-house use.
Simplicity of Nylon Stockings: Pre-filtering your catchment water can be simple and inexpensive. A simple yet effective solution is to place a nylon stocking over the end of the inlet pipe leading to your tank. The nylon stocking acts as a barrier, catching all large debris, leaves, and twigs before they can enter your system.
One of the key advantages of using a nylon stocking as a pre-filter is the ease of maintenance. When it's time to clean your system, you can remove the stocking and replace it with a new one, and your catchment stays cleaner with minimal effort. This small investment of time and resources can pay off significantly in the long run.
