What is a sewer collection system?
A collection system is a network of sewer lines, manholes, pumping stations and other structures used to collect wastewater and transport it to a treatment plant. The Costa Mesa Sanitary District system is a collection system only; treatment and disposal takes place at the Orange County Sanitation District plants in Fountain Valley and Huntington Beach.
What do I do when there is a sewage backup on my property?
Property owners are responsible for maintaining their sewer lateral line until past the point of connection with CMSD's main line (usually in the middle of the street). If you experience a backup in your sewer lateral, contact a plumber to assess the situation. To take a proactive approach to sewer lateral maintenance, consider applying for the District's Sewer Inspection Rebate Program.
Who do I call when there is a sewage backup on public property?
During normal business hours (Monday – Thursday from 7:30 am to 4:30 pm) and (every other Friday 7:30 am to 3:30 pm) contact District Headquarters at (949) 645-8400. For after hours and weekends contact C&R Drains at (714) 641-1545.
What is the leading cause for sewage backups?
There are several leading causes for sewage backups.
Tree Roots – Once inside the pipe, roots will continue to grow and if not disturbed, they will completely fill the pipe with multiple hair-like root masses at each point of entry. The root mass inside the pipe becomes matted with grease, tissue paper and other debris discharged from the property owner. As the roots continue to grow, they expand and exert considerable pressure at the crack or joint where they entered the pipe. The force exerted by the root growth can break the pipe and may result in total collapse of the pipe.
Fats Oil Grease (FOG) – Fats, oil and grease in the sewer can build up on the side walls of pipes and actually reduce the diameter of the pipe. This phenomenon does not just occur in restaurants, but is very common in residential sewers.
Flushable Wipes – While tree roots and FOG have been ahead of the pack for the leading causes of sewer backups, in recent years sewer agencies around the country are dealing with a new problem, flushable wipes. Toilet paper manufacturing companies have been knowingly marketing these products as flushable over the last few years, but wastewater professionals are finding out these products are not safe for sewage systems. Flushable wipes are supposed to be biodegradable and break up like normal toilet paper, but unfortunately they don’t. The wipes will stay firmly intact and do not disintegrate. As a result, they will cling to the interior walls of pipeline and/or get hung up on snags inside the pipe. They will also clog pumps from transporting sewage to treatment plants.
How can I prevent sewage backups?
Tree Roots – Rodding your lateral line and hydrojetting often removes blockages. Plumbers often will thread a flexible metal rod or cable with a cutting tool attached to the end of it into your sewer line. However, this is a temporary fix if tree roots are involved. Eventually, roots will grow back into your sewer line, so be sure to rod your lateral every year. Hydrojetting is more aggressive in removing roots because the line is cleaned with high pressure water.
Fats Oil Grease (FOG) – Never pour grease and oils into drains, toilets or garbage disposals. Pour grease and oil into an empty can and let it sit for a few hours until the grease and oil hardens. Then, throw the can in the trash. Wipe off grease, oils and fatty residue from cookware and dishware using disposable towels and place in the trash.
Flushable Wipes – Do not flush paper and cloth products down the toilet. Examples of products that you should not flush include paper towels, cloth or disposable diapers, flushable wipes, sanitary napkins and certain tampons.
How many miles of sewer mainline do you maintain?
We are responsible for maintaining 224.2 miles of pipeline. We are also responsible for maintaining twenty (20) pump stations.
How am I billed for wastewater collection (sewer) service?
CMSD's customers pay for their solid waste and wastewater services through their property tax bill. Solid waste and wastewater fees appear on the property tax bill as special assessments. To view CMSD’s current solid waste and wastewater collection rates, visit our Rates page. Or, to view your property tax bill, visit the Orange County Treasurer-Tax Collector website.
How does my rate compare to other sewer service rates in the area?
The District historically has one of the lowest rates in Orange County.
What are manholes?
Manholes are circular openings covered by a metal lid that are usually located in the middle (sometimes to the side) of the street. They are used for access to the sanitary sewer main. Only authorized District personnel may remove manhole covers and enter manholes.
If I notice missing, damaged or noisy manhole covers (loose fitting) what do I do?
Please report the occurrence to the District immediately at (949) 645-8400 or on our Service Request Webpage.
What is an Easement?
When a public sewer line crosses private property, the property owner grants the Costa Mesa Sanitary District a right to operate and maintain the sewer line, and this right to use the private property is termed an “easement.” The District is usually granted a 10-foot wide strip of land over the length of the sewer. Easement documents are recorded at the Orange County Recorder’s office.
Who owns and maintains the Easement?
The property owner continues to own the land and has only given up defined rights on the portion of land used for the easement. Maintenance of the property within the easement is the responsibility of the property owner. The property owner continues to use the surface of the land but may not erect a structure in the easement.
Who can enter my property?
The District may access its easements at any time. The District may, on occasion, have a Contractor perform specific tasks on the sewer inside an easement.
Can I make improvements within the Easement?
Easements are typically granted to the District with the understanding that the property owner may make improvements to the surface such as fences, asphalt paving, irrigation and lighting systems or similar improvements. However, structures are never allowed inside an easement.
What is an encroachment in an easement?
An encroachment is a physical intrusion into the limits of the easement. The District may require that any unauthorized encroachments be removed at the property owner's expense.
Are there penalties for locating structures or improvements on an easement?
The property owner may be faced with the costs of removal and any associated damages resulting from unauthorized structures or improvements on land subject to an easement.
Can the District address pests or insects within the sewer system?
If you are experiencing pest or insect issues related to the sewer system, please report it to our Wastewater Superintendent using this contact form.
