“Shorter showers, more efficient toilets and other reductions in indoor water usage have meant less wastewater flowing through sewer pipes, [California] sanitation officials say. With less flow to flush the solids down the system, those solids are collecting and can eventually damage pipes.”

Less Water Flow Means Greater Pipe Degradation
As home and business owners throughout California use various methods to cut water consumption both in and out of their properties, less water is then available to cycle through sewer systems. Lower sewer flow then makes it difficult for waste materials, oils water and other contaminants to cycle through. Best case scenario, this can result in minor sewer buildup or blockage; worst case, it can cause severe clogging, corrosion and pipe breakage at weak joints.
With corrosion comes increased pipe repair and replacement costs. Otherwise healthy sewer pipes will fail prematurely as clogs and chemicals remain stagnant within pipes.
Decreased water flow due to conservation is a particularly troubling problem in Sacramento, where the municipal sewer system is relatively flat compared to other cities in the state. With a flat sewer system, it is already difficult for water and materials to flow at a normal rate; when this rate is lowered, and gravity cannot help waste and waste water along, there is little to push solid materials along.
The people of Sacramento, in this case, are stuck between a rock and a hard place: water has to be conserved in light of the unrelenting draught, and doing so creates hazards for the entire city sewer system.
Dealing With the Issues
One way Sacramento residents can help reduce the likelihood of sewer clogging during low water flow periods is by changing the way they use their plumbing systems – overall reducing the amount of non-fluid materials that enter sewer systems.
This includes knowing what kinds of things you should not flush or dispose of through the sink, such as:
Baby wipes or other kinds of “flushable” wipes – they’re not really flushable, and actually cause millions of dollars in sewer damage annuallyStarchy food products or peelsAny plastic materials, including wrapping or casesPaper towels
Beyond better flushing practices, also steer clear from using chemicals or commercial drain cleaning products, as these products can eat away at sewer pipes from within, causing extra difficulties for pipes with low-flow or stagnant water. […]”<
