1. 2026 Washington Drought Outlook — What to Expect
Washington State has been experiencing a pattern of increasingly severe summer droughts, and 2026 is shaping up to be another critical year. Here’s what the current data shows:
Washington State’s snowpack levels through April 2026 remain below the 30-year average for this time of year, raising concerns about summer water availability — particularly for wells that depend on groundwater recharge.
The key factors shaping your well’s vulnerability to drought this year:
- Below-average snowpack: Mountain snowpack serves as the primary groundwater recharge source for most of Washington. Low snowpack means less water percolates down to replenish aquifers during spring and early summer.
- Rising groundwater temperatures: As surface temperatures climb, groundwater temperatures also rise — which can affect water quality and pump efficiency.
- Extended dry periods: Rainfall patterns in Western Washington have become more erratic, with fewer consistent rain events during the traditional wet season (October–April).
- Increased neighbor drawdown: When neighbors also draw heavily from shared aquifers during drought, your well’s water level can drop — even if your own water use hasn’t changed.
2. Well Head Protection: Your First Line of Defense
Your well head — the exposed top portion of the well casing — is the most vulnerable part of your well system during drought. When water levels drop, contaminants can more easily enter the well from the surface. Here’s how to protect it:
Inspect the sanitary seal
The sanitary seal (or sanitary cap) is a watertight seal at the top of your well casing that prevents surface water, insects, and contaminants from entering. During drought, when surface water is concentrated in fewer areas, the integrity of this seal becomes even more critical. Look for:
- Cracks or corrosion in the well cap
- Visible gaps between the cap and the casing
- Missing or damaged bolts and gaskets
- Pooling water around the well head (indicates a breach)
Grade the ground around your well
The ground around your well should slope away from the casing in all directions — at least a 6-inch drop within a 10-foot radius. This ensures surface water drains away rather than pooling. During drought, you want the maximum amount of available moisture to infiltrate the soil around your well head to help maintain water levels.
Keep the well head area clear
Remove vegetation, debris, and any materials within 10 feet of the well head that could introduce contaminants. Drought concentrates whatever contaminants exist near the surface — keeping the area clear reduces the risk.
3. Pump Maintenance Before Drought Season
A pump that’s not in top condition during drought can mean the difference between having water and going without. Here’s what to do before summer hits:
| Task | When to Do It | Cost (DIY) | Cost (Professional) |
|---|---|---|---|
| Inspect pump wiring and connections | Before drought season | $0–$25 | $150–$300 |
| Check pressure tank air charge | Before drought season | $0–$15 | — |
| Test pump amperage draw | Before drought season | $0 | $100–$200 |
| Clean or replace well screen | Every 3–5 years | $200–$500 | $800–$2,000 |
| Inspect drop pipe and fittings | Before drought season | $0–$50 | $200–$400 |
| Professional well inspection | Annually (best: late spring) | — | $300–$600 |
Key pump maintenance checklist
- Test the pump’s gallon-per-minute (GPM) output: During drought, a pump that normally delivers 5–7 GPM might drop to 2–3 GPM. Know your baseline now so you can detect changes early.
- Check your pressure switch settings: Standard settings are 40/60 psi (pump turns on at 40, off at 60). If your pump is short-cycling (turning on/off rapidly), the air charge in your pressure tank may be depleted.
- Listen for unusual sounds: Grinding, screeching, or rapid clicking from your pump system indicates mechanical problems that should be addressed before drought.
- Measure your well depth vs. water level: Use a well tape or water level indicator. If your water level has dropped significantly compared to last year, you may need a deeper pump or additional water storage.
4. Water Conservation Strategies for Well Owners
During drought, conserving water isn’t just about reducing your bill — it’s about extending your well’s sustainable yield for as long as possible. Here are the most effective strategies:
Indoor conservation
- Fix all leaks immediately: A running toilet wastes 200+ gallons per day. A drip from a faucet wastes ~15 gallons per day. During drought, every gallon counts.
- Install low-flow aerators: $10–$20 per faucet. Reduces flow by 30–50% with minimal impact on usability.
- Audit your water usage: Track daily consumption. The average U.S. household uses ~80 gallons per person per day. Aim to reduce by 20% during drought months.
- Run dishwashers and washing machines only with full loads: This is especially important for well owners — every cycle pulls from your limited groundwater supply.
Outdoor conservation
- Water lawns and gardens early morning or after sunset: Reduces evaporation by up to 30%.
- Install a drip irrigation system: 50–70% more efficient than sprinklers. The upfront cost ($500–$2,000) pays for itself within one drought season.
- Mulch all garden beds: 2–3 inches of organic mulch reduces soil moisture loss by up to 70%.
- Native plants for landscaping: Choose drought-tolerant species that require little to no supplemental watering once established.
- Consider drought-tolerant lawn alternatives: Clover lawns, ornamental grasses, and gravel gardens use a fraction of the water of traditional turf.
5. Water Storage and Backup Systems
The single most important drought preparedness step for well owners is building water storage capacity. Here’s your options:
Storage Tank (Best Overall Solution)
Capacity: 500–5,000 gallons
Cost: $400–$3,000 (tank) + installation
Why it matters: A 500-gallon tank provides roughly 3 days of drinking water for a family of four. A 1,000-gallon tank can cover a week. During extended drought when your well’s output drops, this buffer can be the difference between inconvenience and emergency.
Underground Cistern (Permanent Solution)
Capacity: 1,000–10,000+ gallons
Cost: $3,000–$15,000 installed
Why it matters: Underground cisterns are insulated from temperature extremes, don’t take up above-ground space, and can last decades. Ideal for permanent drought resilience, especially in areas with severe drought cycles.
Granny Flat / Rainwater Catchment Backup
Capacity: Variable based on roof area and catchment system
Cost: $1,000–$5,000 for a basic system
Why it matters: While Washington summers are generally dry, winter and spring rainfall can be captured and stored for summer use. Even a simple 500-gallon rain barrel system reduces your well’s burden during summer months.
Quick-Reference: How Much Water Storage Do You Need?
- Drinking only (1 person): 2 gallons/day × 30 days = 60 gallons minimum
- Drinking + cooking (1 person): 5 gallons/day × 30 days = 150 gallons minimum
- Family of 4 (drinking + cooking): 20 gallons/day × 7 days = 140 gallons buffer recommended
- Family of 4 (all household use): 50 gallons/day × 7 days = 350 gallons buffer recommended
- With irrigation needs: Add 500–2,000+ gallons depending on garden/lawn size
6. Water Quality Changes During Drought
Drought doesn’t just affect water quantity — it can significantly impact water quality. Here’s what to watch for:
| Parameter | What Drought Does | What to Do |
|---|---|---|
| Nitrate levels | Increase — contaminants become more concentrated in lower water levels | Test annually (best: late summer). If nitrate exceeds 10 ppm, install reverse osmosis. |
| Bacteria (E. coli) | Can increase — surface contamination more easily reaches the well during low water | Test at first sign of change in taste/odor. If positive, shock chlorinate and retest. |
| TDS (Total Dissolved Solids) | Increase significantly — less water = higher mineral concentration | Test TDS. Above 500 ppm affects taste; above 1,000 ppm may need treatment. |
| pH levels | Can shift — drought concentrates acidic or alkaline compounds | Test pH. Below 6.5 can corrode pipes; above 8.5 causes scaling. |
| Iron/Manganese | Increase — minerals precipitate at lower water levels | Test if water develops rust color or metallic taste. Install oxidation/filtration system if needed. |
| Turbidity (cloudiness) | Can increase — sediment stirred up from lower water table | Install sediment filter if cloudiness occurs during drought periods. |
Bottom line: Test your well water at the start of drought season (May) and again in late summer (September). Any significant changes between tests indicate that drought is affecting your water quality and may require treatment adjustments.
7. Managing Well Water for Irrigation During Dry Months
If your well also serves irrigation needs, drought requires special considerations:
- Divert irrigation to off-peak hours: Water your lawn and garden at 4–6 AM or after 8 PM to minimize evaporation loss.
- Zone your irrigation: Water different zones on different days. This gives your well a chance to recover between watering cycles and prevents over-drawing in a single day.
- Reduce lawn area: Consider converting high-water-use lawn areas to drought-tolerant landscaping. Even reducing lawn by 25% can dramatically reduce your well’s summer burden.
- Monitor your pump runtime: If your pump is running longer than usual to fill the pressure tank, your water level may be dropping. Reduce irrigation accordingly.
- Collect gray water: Showers, laundry, and dishwater can be collected and used for non-food garden irrigation — reducing your well’s outdoor load.
8. Building Your Well Drought Emergency Plan
Even with the best preparation, a severe drought can overwhelm even a well-maintained system. Here’s how to build your emergency plan:
Your Well Drought Emergency Kit
- Bottled water: 1 gallon per person per day for 7 days minimum (28 gallons for a family of four)
- Water purification tablets: Emergency backup for treating well water if contamination is suspected
- Manual water pump or hand pump: If your electric pump fails, a manual pump can still draw water from your well
- Water storage containers: Food-grade buckets with tight-fitting lids for emergency water collection
- Well professional’s contact info: Have your well contractor’s phone number readily accessible
- Well permit and documentation: Keep your well log, construction details, and permit copies in a waterproof container
When to call a well professional during drought:
- Your well’s water output drops below 50% of its normal rate
- You notice a sudden change in water quality (taste, odor, color)
- Your pump runs continuously without building pressure
- Your well produces sediment or sand
- The well cap or sanitary seal is damaged
