Why Trenchless?
Trenchless sewer replacement is not only the newest method to replace your sewer but is the best! Here's how it works. An insertion and retrieval pit is dug. The trenchless bursting head is inserted into the old sewer pipe. A heavy cable is pushed through the pipe from the retrieval pit. A special hydraulic ram is attached to the cable and pulls the bursting head through the old pipe. At the same time, new polyethylene pipe is pulled along with the bursting head. Every 20' the pipe is fused together with another special tool. Our system can pull up to 100' of pipe with just two pits.

 "Can you imagine digging up this yard for
a sewer replacement? That is why we
did it "Trenchless". |

The new Pipe provides a continuous seamless sewer to the point of connections. Cleanouts are provided along the path of the sewer as needed. This system eliminates the bell and spigot connections every 36" with clay pipe and coupling every 10' with cast iron. Fewer connections mean less potential failure points.

Polyethylene piping is the preferred material for municipal sewer replacement in Alameda and Contra Costa Counties

The Polyethylene Story.
Polyethylene was first developed by Phillips Petroleum in 1951. Today's high density materials contain "Marlex Resins" and are more versatile than ever. Polyethylene has been mainly used for industrial gas and chemical pipelines. There are tens of thousands of miles of this pipe in service. Later it was used for domestic water supply and most recently for sanitary sewers. This is the preferred material for municipal sewer replacement in Alameda and Contra Costa Counties. No wonder it's the choice of Harry Clark Plumbing and Heating.

FREQUENTLY ASKED QUESTIONS (FAQS) FOR SEWER LATERAL REPLACEMENT
Q: What is a "sewer lateral?"
A: A sewer lateral is the portion of the sanitary sewer line which connects a house’s or business plumbing to the districts sewer system. Typically, most but not all, of the “sewer lateral” is on the private property, while other portions of the sewer system, the “sewer main”, is usually all in the public right away.
Q: Why is there so much concern over private "sewer laterals?"
A: Sewer laterals which are in poor condition present two problems: (1) faulty sewer lines can leak raw sewage into the ground which may be a public health issue; (2) storm water can invade the poorly sealed sewer lines which overloads the waste treatment plant. The overloaded plants then spill partially or untreated sewage into the bay. The results are serious bay pollution, and fines from the EPA to the sanitary districts.
Q: What are the problems associated with the sewer laterals?
A: Most homes in our service area were built before 1950, and often have never replaced their original sewer laterals. Over time these pipelines, generally made of clay, crack, become disjointed or displaced, and have root intrusion which cause leakage and backups. Many of these laterals lack the proper cleanout access for clearing of blockages.
Q: Whose responsibility is the maintenance of the sewer lateral?
A: In most cities, districts or local jurisdictions, the maintainace of the sewer lateral, up to and including the connection to the main is the responsibility of the private home owner. The district is responsible for maintaining the sewer main. In some cities you are only responsible to the curb.
Q: At what point am I required to replace the sewer lateral?
A: You may voluntarily choose to replace the sewer lateral at any time you feel it is necessary. This may be when you have experienced frequent backups, have had video inspections which visually show problems, or
are about to sell your home. Most districts require some type of compliance certifications for the sewer lateral at the time a home is sold, transfers ownership, or has a remodel / addition project. This is usually required before the close of escrow or final of project.
Q: Do I need a video to replace my sewer lateral?
A: Yes. The point of the video is to demonstrate that the sewer lateral is in compliance, identify problems that can be repaired, or determine if replacement is needed. If the sewer lateral needs replacement the video provides information needed such as the sewer depth, location, grade, and relation to other utilities.
Q: Is Trenchless method the best for sewer lateral replacement?
A: Yes. Trenchless sewer replacement is best when it can be used. It has 90% fewer mechanical connections, is a seamless pipe with 100 year service life, and is pliable for earth movement, settling, and earthquakes. The process is the least invasive for both landscapes and hardscape.
Q: If Trenchless method cannot be used what else is available?
A: Cast iron pipe is the best if the Trenchless method cannot be used. There are special couplings designed for underground use and the pipe comes in 10’ lengths.
