  • Private Sewer Systems Defects and Overflows How Do Sewer System
    Private Sewer Systems Defects and Overflows Most sanitary sewer systems are constructed as a network of manholes and pipes that flow from each building that generates sewage to a wastewater treatment plant. Private services, also called laterals, are pipes from the building to the sewer main. In some areas, the public system owns and maintains the “lower lateral” from the sewer main to the edge of the easement or right-of-way, and the private property owner owns and maintains the “upper lateral” the remainder of the way to the building. In other areas, the private property owner owns and maintains both the lower and upper laterals. Finding and fixing sewer defects on private property sewer systems can prevent sewer overflows and backups that can cause health hazards, inhibit economic growth, and result in long-term environmental damage. How Do Sewer System Defects Cause Overflows? Private sanitary sewer systems, the earliest of which were built in the mid 1800s, carry domestic wastewater away from private properties separately from stormwater. These systems have deteriorated over the years, are typically not maintained or replaced due to funding, and their ability to transport sanitary wastewater has been compromised due to population growth. As a result, these systems can experience separate sanitary sewer overflows (SSOs) both on public and private property. SSOs are generally caused by infiltration that occurs when clean water such as groundwater enters the sanitary sewer through defects in the system or inflow from stormwater that enters the system through defects and illegal connections. SSOs can also be caused by inadequate pipe sizes when population growth exceeds the original design conditions.

  • Sump Pump Information Card
    Sump Pumps into the Sanitary Sewer Create Health and Safety Risk! Aside from the fact that connecting sump pumps to the sanitary sewer is illegal, it can cause significant health and safety risks. Sump pumps are designed to pump groundwater and rain water. Generally, the sanitary sewer pipe in the street is only 8 inches in diameter, and often the pipe slope is not very steep. Many 8 inch sewer pipes are installed with a slope of 0.4%. This means that for every 100 feet of pipe, the pipe goes downhill less than 5 inches. This low slope condition is very common in Washington County sewer collection systems, which means there is only so much sewage water that can flow through this pipe. For this type of sewer pipe, about 300 gallons of water can flow through it in a minute. If more sewage than this tries to get through the pipe in the street, the sewage will surcharge, that is start filling up the sewer lateral pipes that run to the sewer main from houses. When even more sewage or extra water is sent to the sewer pipe, it will surcharge even farther, eventually pushing back into someone’s basement. The sewage might come out of a neighbor’s basement toilet or washing machine drain for example. If hooked up to a house’s sewer lateral, a half-horsepower sump pump will pump about 60 gallons to the sewer each minute. That means that if 5 pumps are connected to the sewer, it will be full. Normal sewage flows often fill the sewer main more than half-way already.

  • Reducing Inflow and Infiltration Part 1: Sump Pumps
    REDUCING INFLOW AND INFILTRATION PART 1: SUMP PUMPS In this series of articles I will discuss cost effective ways of reducing inflow and infiltration to our wastewater facilities. Inflow and infiltration are defined below. INFLOW: “THE WATER DISCHARGED INTO A SEWER SYSTEM AND SERVICE CONNECTIONS FROM SUCH SOURCES AS ROOF DRAINS, SUMP PUMPS, FOUNDATION DRAINS, COOLING WATER DISCHARGES, MANHOLE COVERS, COMBINED SEWER SYSTEMS, CATCH BASINS, STORM WATER AND SURFACE RUNOFF” INFILTRATION: “THE WATER ENTERING SEWER PIPES AND SERVICE CONNECTIONS FROM THE GROUND. DEFECTIVE PIPES, JOINTS, CONNECTIONS AND MANHOLE WALLS ARE COMMON LOCATIONS OF INFILTRATION” Sump pumps are used by some home owners to remove unwanted water from basements. Unfortunately, a lot of these sump pumps are hooked into home owner sewer lines. This is a direct connection to the sewer collection system and results in extra influent flow, that the collection system has to handle and the wastewater facility has to treat. This treatment of unwanted ground/surface water wastes valuable facility capacity and restricts the amount of future hookups and growth of a community. A huge waste of money and time will result in wastewater facility upgrades due to lack of capacity that has been taken up by inflow and infiltration sources. Sump pump discharges can also cause wwtfs to use extra electricity, chemicals and can affect the efficiency of the treatment process. A typical homeowner sump pump (40 gallons/minute) running 10 minutes per hour can pump 9,600 gallons per day. If there are 20 similar sump pumps in your community, 192,000 gallons of unwanted water is being sent to your wastewater facility in one day! There are several ways to ensure that sump pumps are not tied into sewer collection systems: -Education, Many home owners do not realize the problems they are causing by hooking sump pumps into their sewer lines.

  • Sump, Sewage and Effluent Pump Selection Guide
    Sump, Sewage and Effluent Pump Selection Guide This guide is designed to assist individuals with selecting the proper style and size pump for a submersible pumping application. There are a few considerations to factor in when selecting a pump, pump operation, horsepower, voltage and phase, and GPM total (gallons a pump will move in 1 minute). This guide will provide information for the basic residential or light commercial/industrial submersible pump selection process. Pump Operation Selection: Submersible Pump- A pump that has its motor and electrical components sealed in a protective housing to permit use under water or other liquid conditions. Sump Pump- Manufactured to remove unwanted drain water from a basement sump pit and drain tile systems; parking lots and low land areas where lack of a gravity drain allows water to pool. Sump pumps are rated for ground or waste water mostly clear of solids (nothing more than silt and ground water solids less than ¼” diameter). Mostly installed where basement flooding is a problem, and to remove moisture from around foundations in order to prevent mold/mildew build-up. Discharge pipe size ranges from 1” and up, based on existing drain line applications. Effluent Pump- Engineered for “gray” water or waste water (mostly liquid) applications that contains solids of ¾” in diameter or less. This is often waste water that has passed through a septic or settling tank and needs to be pumped into an additional system or treatment area. Discharge pipe size ranges from 1 ½” and up, based on existing drain line applications. Sewage Pump- Mostly used in raw sewage applications or dewatering where up to 2” diameter solids must be passed through the pump.

  • Sewer Information the City of Port Townsend Has 77 Miles of Sanitary Sewer Lines, 1,205 Manholes and 7 Lift Stations Within Its Sanitary Sewer System
    City of Port Townsend Sewer Information The City of Port Townsend has 77 miles of sanitary sewer lines, 1,205 manholes and 7 lift stations within its sanitary sewer system. Sanitary sewer system problems are not common and the Public Works Department's maintenance procedures are intended to avoid or minimize such problems in the system to the maximum extent possible. The Department attempts to continually maintain its portion of the sanitary sewer system to be as trouble free as possible. The City is responsible for the sewer mains. The Customers are responsible for their sewer service line, or side sewer. This runs from the residence/business to the connection to the sewer main line. Sewer System Maintenance Program Each year, the Public Works Department cleans approximately one-quarter of the City's sanitary sewer lines. Cleaning begins in March, early April through October. Some of the lines are cleaned more frequently to keep them functioning properly. The sanitary sewer lines are cleaned using high performance sewer cleaning equipment. A cleaning nozzle is propelled from one manhole to the next using water under high pressure (1,500 to 2,000 PSI). The nozzle is then pulled back to the starting manhole. As the nozzle is pulled back, water scours the inside of the sanitary sewer pipe. Any debris in the pipe is pulled back with the water. The debris is removed from the manhole with a vacuum unit. If roots are found, they are cut with a root cutter. This process is repeated on every sewer line cleaned. We clean and root cut any problem areas one to two times per year.
