PVC conduit is the lightest in weight compared to other conduit materials and is usually lower in cost than other forms of conduit. It is available in three different wall thicknesses, with the thin-wall variety only suitable for embedded use in concrete, and heavier grades suitable for direct burial and exposed work. The various fittings made for metal conduit are also made for PVC. The plastic material resists moisture and many corrosive substances, but since the tubing is non-conductive an extra bonding (grounding) conductor must be pulled into each conduit. PVC conduit may be heated and bent in the field. Joints to fittings are made with slip-on solvent-welded connections, which are set up rapidly after assembly and attain full strength in about one day. Since slip-fit sections do not need to be rotated during assembly. Since PVC conduit has a higher thermal coefficient of expansion than other types, it must be mounted so as to allow for the expansion and contraction of each run. Care should be taken when installing PVC underground in multiple or parallel run configurations due to the mutual heating effect of cable.
BRIGHT WATER CONDUIT PIPE MEETS THE REQUIREMENTS PRESCRIBED BY THE FOLLOWING STANDARDS ORGANIZATIONS:
BRIGHT WATER offers a complete line of Electrical Conduit pipe products which include: Schedule 40 and 80 Conduit (NEMA TC-2, ANSI/UL651), Encased and Direct Burial Conduit (ASTM F512, NEMA TC-6 & 8 and/or ANSI/UL 651A), and Type C Telephone Duct. All BRIGHT WATER Electrical Conduit pipe products are offered in 4-meter laying lengths (10-foot and 20-foot lengths are also manufactured on special order by the customer). This means that more ground can be covered during installation while eliminating the cost of unnecessary joints.
PVC pressure pipes are manufactured from un-plasticized polyvinyl chloride polymer (a thermoplastic material) using the extrusion process. PVC (also known as PVC pipes are widely accepted for use in water supply, irrigation, and sewerage rising mains.
Their high strength-to-weight ratio together with exceptional resistance to corrosion or chemical attack makes these pipes ideal for major infrastructure applications.
BRIGHT WATER PVC pressure pipes meet the requirements of AS/NZS 1477 “PVC pipes and fittings for pressure applications” and the Water Services Association of Australia (WSAA) Reticulation Code WSA 03.

In modern plumbing, a drain-waste-vent (or DWV) is part of a system that removes sewage and gray water from a building and regulates air pressure in the waste-system pipes, facilitating flow. Waste is produced at fixtures such as toilets, sinks, and showers, and exits the fixtures through a trap, a dipped section of pipe that always contains water. All fixtures must contain traps to prevent sewer gases from leaking into the house
The venting system, or plumbing vents, consists of pipes leading from waste pipes to the outdoors, usually through the roof. Vents provide a means to release sewer gases outside instead of inside the house

Casing pipes and screens ensure that the water well remains a perennial source of clean water. Some years ago the choice was only metal pipe and Screens. The disadvantages were corrosion of casing pipes, determination of screens, and formation of bacteria, resulting in the abandonment of wells and, even worse contamination of the water source.
PVC well casing and screen are widely used because it is light strong, easy to install durable corrosion resistant, and relatively inexpensive. The choice of any material depends upon its strengths and weaknesses in relation to the particular intended use. Condition at a water well drilling site and within a borehole or generally aggressive. PVC casing and screens are easily able to withstand most conditions but it is important for a driller engineer or hydrogeologist to be aware of conditions or circumstances that might prejudice the integrity of PVC and consequently the borehole. The aim is to provide a basis for the correct selection and handling of PVC casing and screen.
TYPES OF SCREEN DESIGN:
PPRC Pipe and Fittings produced from PP (Polypropylene Random Copolymer) raw material according to TS 9937, TSE EN ISO 15874, DIN 8077, DIN 8078, DVGW W544 standards indispensable solution for today’s indoor cold and hot water piping systems has advantages such as its lightweight and smoothness, smooth and bright internal surfaces, calcification and rust-free, hygienic, easy to assembly and takes the place of galvanized pipes. Used in any kind of indoor hot and cold water pipe systems, PPRC Pipe and Fittings are produced from the Type-3 class raw material, also called PP-R (Polypropylene Random Copolymer). PP raw materials are grouped under three classes in terms of thermal, pressure, and chemical resistance.
PP-H (Polypropylene Homo polymer)
PP-B (Polypropylene Block polymer)
PP-R (Polypropylene Random polymer)
Type-3 raw material has higher performance and superior properties than Type-1 and Type-2 raw materials in terms of their physical and chemical properties. The most important property of this raw material is its high resistance against heat and chemical effects. Thanks to this resistance, PPRC Pipe and Fittings produced from PP-R raw material are used successfully in cold and hot water piping systems. Since the monomer structure of the PP-R raw material forms a random chain, it does not allow any biological substance to be present in its body and so this provides PPRC Pipe and Fittings produced from PP-R raw material with superior properties of non-color, taste, and smell formation. When used under proper pressure and temperature values, the life of PPRC Pipe and Fittings is more than 50 years.

HDPE pipe is the ideal piping solution for public and private potable water systems. HDPE pipe features a service life of over 100 years and has the versatility to perform in a variety of conditions. HDPE pipe provides a logical, low-maintenance investment in municipal and private potable water applications. Meeting the challenges of the 21st century Piping made from polyethylene is a cost effective solution for a broad range of piping problems in municipal, industrial, marine ,mining, landfill, duct and agricultural applications. It has been tested and proven effective for above-ground, surface, buried, slip-lined, floating, and sub-surface marine applications. High-density polyethylene pipe (HDPE) can carry potable water, wastewater, slurries, chemicals, hazardous wastes, and compressed gases. In fact, polyethylene pipe has a long and distinguished history of service to the gas, oil, mining, and other industries. It has the lowest repair frequency per mile of pipe per year compared with all other pressure pipe materials used for urban gas distribution. Polyethylene is strong, extremely tough, and very durable. Whether you're looking for long service, trouble-free installation, flexibility, resistance to chemicals or a myriad of other features, high-density polyethylene pipe will meet all your requirements.
