What is sewage treatment?
The process of removing contaminants from wastewater and household sewage, both runoff, domestic, commercial and institutional. Its objective is to produce an environmentally safe fluid waste stream and a solid waste (treated sludge) suitable for disposal or reuse (farm fertilizer).
Where does wastewater comes from?
Wastewater comes from flushing the toilet, bathing, washing, and general cleaning. All this goes down the drain and into a pipe, which joins a larger sewer pipe under the road.
Factors that affect the flow of waste water in the pipes
Fats, oils or grease (FOG) from cooking, cars, and industrial machines create plumbing problems and public sewers.
When warm FOG is disposed in sink it flows easily
When FOG cools down inside pipelines, it solidifies causing major pipeline damages and slow water flow.
Industrial Wastewater?
Industrial wastewater includes the runoff and leachate from areas that receive pollutants associated with industrial or commercial storage, handling or processing facilities. This also usually mixes with the wastewater from our homes and goes directly to one of Houston's waste water facilities.
Storm Water Data in Houston
Houston receives about 50 inches of rainfall per year.
September is Houston’s rainiest month, with
