If your utility bill feels like a mystery, you’re not alone. Sewerage and wastewater charges often make up a large chunk of your total water bill—sometimes more than the cost of the water itself. Understanding what these fees cover and how they’re calculated is the first step toward reducing them.
In this guide, we’ll break down everything you need to know about sewerage and wastewater charges. More importantly, we’ll share proven strategies to lower them—and highlight some handy tools to keep your savings on track, like the Wooden Money Saving Box that can help you stash away $10,000.

What Are Sewerage and Wastewater Charges?
Sewerage and wastewater charges are fees your utility company collects to treat the water that goes down your drains. When you flush a toilet, run a washing machine, or take a shower, that water enters the municipal sewer system. The utility must clean it before releasing it back into the environment, and you pay for that process.
Key difference: Water supply charges cover the clean water coming in, while sewerage charges cover the dirty water going out.
Most bills split these into two parts:
| Charge Type | What It Covers | How It’s Billed |
|---|---|---|
| Fixed charge | Maintenance of pipes, treatment plants, and administration | A flat monthly or quarterly fee |
| Volumetric charge | Actual volume of wastewater treated | Based on water usage (often 80–100% of your metered water consumption) |
| Stormwater drainage | Managing rainwater runoff from your property | Usually a fixed annual levy |
| Trade waste (business only) | Treating industrial-strength effluent | Measured by volume and pollutant load |
Why Are Sewerage Charges So High?
Sewerage isn’t cheap. Treatment plants require constant energy, chemicals, and skilled labor. Aging infrastructure in many cities needs expensive upgrades. Environmental regulations also push up costs—cleaner discharge standards mean more advanced treatment.
But here’s the thing: you can lower your sewerage bill by reducing the amount of wastewater you send down the drain. Since most volumetric sewerage charges are directly tied to your water consumption, saving water equals saving money on both sides of the bill.
How to Lower Your Sewerage and Wastewater Charges
Start with these practical steps:
- Fix every leak. A dripping faucet can waste thousands of gallons a year, adding to both your water and sewer charges.
- Install water-efficient fixtures. Low-flow showerheads, dual-flush toilets, and aerators cut wastewater dramatically.
- Take shorter showers. A 10-minute shower uses about 20 gallons. Cutting to 5 minutes saves half that volume.
- Only run full loads. Whether it’s the dishwasher or washing machine, always wait until you have a full load.
- Consider greywater systems. If local codes allow, divert used water from showers and laundry to irrigate your garden instead of sending it to the sewer.
- Check for rebates. Many utilities offer cash back for installing high-efficiency toilets or washing machines.
Read Your Bill for Errors
Look at your sewerage volumetric charge. Is it based on 100% of your water consumption? Some utilities apply a “winter average” method—they use your lowest winter usage as the baseline for the year, because outdoor watering is minimal. If your bill doesn’t use this method, you might be paying for water that never enters the sewer (like garden irrigation). Request a winter averaging adjustment if you water your lawn heavily in summer.
Tools and Trackers to Help You Save Money
Lowering your sewerage bills often requires upfront investment in efficient fixtures or simple behavior changes. One of the easiest ways to stay motivated is to use a savings challenge tool to put aside money each time you save. These physical trackers make your progress visible and rewarding.
The 100 Envelopes Money Saving Challenge offers a simple system to save $5,050 by filling numbered envelopes over time. It’s perfect for building a fund for water-saving upgrades like a smart irrigation controller or low-flow toilet.
For a more comprehensive approach, the SKYDUE Budget Binder lets you track all your household expenses—including utility bills—so you can see exactly how much you’re saving after implementing water-saving measures.
Using a dedicated savings box like the $7.99 Wooden Savings Challenge Box gives you a tactile way to watch your savings grow. Every time you fix a leak or choose a shorter shower, drop in a dollar—you’ll be amazed how quickly it adds up.
Additional Tips for Reducing Water Waste Indoors
- Upgrade to high-efficiency toilets (HETs). They use 1.28 gallons per flush or less, compared to older models that use 3.5+ gallons.
- Install faucet aerators. These cheap devices slash flow without sacrificing pressure.
- Use a rain barrel. Collect rainwater for outdoor plants instead of tap water—every gallon not used is a gallon not going to the sewer.
- Run your irrigation on a smart schedule. Avoid watering during rain, and use drip irrigation for gardens instead of sprinklers.
When to Consider a Water Audit or Rebate
Many local utilities offer free or low-cost water audits. A technician will inspect your home, check for leaks, and recommend specific upgrades. They often leave you with efficient showerheads and faucet aerators at no charge.
Check your utility’s website for rebates on:
- High-efficiency toilets
- Clothes washers with WaterSense or ENERGY STAR labels
- Rain barrels or cisterns
- Soil moisture sensors for irrigation
Your savings from these rebates can be funneled into a savings challenge binder, helping you prepare for future bill increases or other home efficiency projects.
FAQ: Sewerage and Wastewater Charges
What is a sewerage charge on my water bill?
It’s a fee for collecting and treating the wastewater that leaves your home. It typically includes a fixed service charge and a volumetric charge based on how much water you use (since most of that water goes down the drain).
Can I reduce my sewerage charge by using less water?
Yes. If your sewerage volumetric charge is tied to your water consumption (as it usually is), using less water directly reduces that part of the bill. Fixing leaks and using efficient fixtures are the most effective ways.
Do I have to pay sewerage charges if I have a septic tank?
No. If you’re not connected to the municipal sewer system, you shouldn’t pay sewerage charges. However, you may still have a stormwater drainage charge if your property drains into public systems. Check your bill carefully.
How are sewerage charges calculated?
Most utilities base them on the volume of water you consume, multiplied by a sewerage rate. Some use a “winter average” method to better reflect indoor use. Others add a flat fee for fixed costs. Always look for the line item labeled “sewer” or “wastewater.”
