Our landscape department often gets questions on good ways to add green space on your property without overtaxing limited water supplies.
The recent ditch outage caused by the late February winter storm got us thinking about water conservation. With winter storms and summer droughts, Tuolumne County has a unique relationship with water. Whether you draw water from a private well or purchase your water from the Tuolumne Utility District (TUD) – all of us can benefit from finding ways to save and efficiently use our water. Using a greywater system is a cost-effective way to manage your water use.
A greywater system is a water recycling setup that captures gently used water from sources such as bathroom sinks, showers, bathtubs, and washing machines, and repurposes it for non-potable uses like landscape irrigation or toilet flushing. Unlike blackwater (water from toilets or kitchen sinks), greywater contains minimal contaminants and can be safely reused when properly filtered and distributed. Greywater is perfect for watering your landscape, but is not recommended for watering edible plants.
Greywater systems can benefit the environment and your wallet. By reusing water that would otherwise go to waste, households can significantly reduce their overall water consumption, lowering monthly utility bills and conserving a vital natural resource. Greywater irrigation is especially valuable in drought-prone areas, promoting healthy landscapes without increasing demand on water supplies. Plus – reducing the volume of wastewater entering your septic can extend their lifespan and decrease maintenance costs.
The cost of installing a basic manual diversion setup—where greywater is diverted directly to garden beds—can start at a few hundred dollars for materials like piping and valves. More advanced systems that include filtration units, storage tanks, pumps, and automated controls can range from around $1,000 to $5,000 or more, especially if professional plumbing work is required. Some regions offer rebates or incentives for water-saving installations, which can help offset upfront expenses.
