When it goes down the drain, it’s gone for good, right? Wrong. Whether you use the toilet or the sink, it all flows through the same sewer line in your home. While wipes and grease may “disappear” when flushed or poured down the drain – they do not dissolve fast enough to flow through the system like toilet paper. They build up in pipes and block your sewer line.

Every day the City of Round Rock removes thousands of pounds of wipes, grease, and other problematic material from the system.

These materials do not break down before reaching the treatment plant. They get lodged in equipment and pipes, clogging up the system and damaging pumps and equipment. This results in higher water costs for customers because of the constant maintenance and more frequent equipment replacement.

Don’t Stop the Flow

Wastewater treatment technologies and processes are designed to break down bodily waste and toilet paper ONLY.

If it Can’t Flow, it Overflows

An overflow is a very nasty, costly mess that has to be cleaned up and paid for immediately. This can be devastating to property owners, renters, and businesses as these expenses are generally not covered by homeowner’s insurance.

Overflows result in:

  • Property damage
  • Plumbing problems
  • Nasty cleanup
  • Replacement of material goods
  • Health issues

How to Prevent Sewer Back-Ups

Grease and Wipes Clog Pipes! 

  1. Only flush toilet paper and bodily waste.
  2. Toss wipes (even “flushable) in the trash, not in the toilet. Here’s why
  3. Put grease in the trash, not in the sink. Collect grease in a can and when full, put it in the trash (Request a FREE lid to secure leftover grease)
  4. Scrape excess grease and food scraps into the trash
  5. Keep strainers in your drain to catch food scraps and solids

All drains in your home flow to the same sewer line. Whether you use the toilet or the sink, what goes down flows through the twists and turns in your home plumbing before making its way to the City’s wastewater system. These twists and turns are prime places for waste that didn’t break down to lodge. 

Toilet paper is the only product designed to break down fast enough to flow through the pipes freely. Wipes, even those labeled “flushable,” do not breakdown like toilet paper and should never be flushed.

Plumbing problems are often caused by flushing materials that are not flushable. While many products may “flush” they do not dissolve fast enough to flow through the system like toilet paper. They build up in pipes and block your sewer line. 

Did You Know - These Don't Go?

There are many misconceptions about what can be flushed or poured down the drain, but as a general rule: If it isn’t body fluid or toilet paper, it doesn’t go. Protect your home and the quality of our water by disposing of these products properly.

No Wipes in the Pipes!
Even those labeled “flushable” – they are too thick and do not disintegrate easily. Wipes are designed to absorb moisture and stay intact when wet, which makes them tough enough to clean with, but too tough to flush.

While toilet paper breaks down in anywhere from a minute to four minutes, wipes can take eight days to dissolve. When flushed, they accumulate and block pipes and pumps.

These paper products are thicker than toilet paper, and do not disintegrate as quickly. They are designed to absorb moisture and stay intact when wet, which makes them great for messes and sniffles, but bad for pipes and pumps.

Unfortunately, current water treatment technology does not remove chemicals found in drugs. When medication is flushed or rinsed down the drain, the dangerous chemicals get pumped into lakes and creeks, contaminating water supplies and wildlife downstream.

Grease may go in as a liquid, but as it cools it becomes a pipe-clogging wax. Pour leftover grease in a can then toss in the trash. Request a FREE Can it…Don’t Drain It kit by emailing Don’t Stop the Flow. Learn more at Cease the Grease.

Leftover paint, pesticides, paint remover, and other household products contain chemicals that are hazardous to people, animals, plants, and fish, and should never be poured down the drain, on the ground, into storm sewers, or put out with the trash.

You can bring these products to any of our Household Hazardous Waste (HHW) Collection events. Many of the products are made available to residents at no cost and the rest are disposed of in an environmentally safe manner and the containers recycled.

Feminine hygiene products, such as tampons and sanitary napkins, are designed to absorb liquids instead of breaking down like toilet paper. They are made of fibers that absorb moisture and expand, which prevents safe passage through your pipes. Flushing these products can easily result in a clogged sewer line.

Wastewater System

The Brushy Creek Regional Wastewater System (BCRWWS), which consists of two wastewater treatment plants and over 300 miles of collection lines, is jointly owned by the Cities of Round Rock, Cedar Park, Leander, and Austin. The City of Round Rock began overseeing all operations and maintenance of the BCRWWS on October 1, 2018.   

The City of Round Rock has a collection system rehabilitation program that includes cleaning and videoing the collection system, as well as inspecting and correcting “problem” areas that require regular maintenance. This program is funded through water and wastewater utility funds.

Lift Stations

The City of Round Rock owns and operates 12 lift stations that pump wastewater to gravity sewer mains or the Brushy Creek Regional Wastewater Treatment Plant.

Wastewater Treatment

The two wastewater treatment plants (WWTPs), known as East WWTP and West WWTP, are located in Round Rock and treat wastewater within the Brushy Creek, Onion Creek, Chandler Creek, and McNutt Creek watersheds.

The City’s wastewater collection system is currently covered under the Wastewater Discharge Permit held by the Cities of Round Rock, Cedar Park, and Austin for the BCRWWTP. This facility was recently re-rated for an average maximum flow of 25 million gallons per day from the plant’s regional customers. The regional customers include the Cities of Round Rock, Cedar Park, Leander, and Austin, as well as the Fern Bluff and Brushy Creek Municipal Utility Districts.
