Sanitation and Sewage Technologies


1. Water Supply Systems

The supply of sustainable water in quality quantity is a key factor for an adequate urban and rural development.

The establishing of water supply projects typically consist of developing and preserving of source of water, water treatment plants (WTP), conveyance system such as conduits and pipes, storage of water and pumping stations.

BJIS and P2W developed a modern network analysis methods and software tools to design cost-effective and optimized water supply projects.


2. Water and Wastewater Treatment Plants

Over the many years of collaboration between BJIS and P2W the design of water and wastewater treatment plants has been a special field of expertise for both parties, as seen in some of the companies’ most challenging projects and over the years, dozens of treatment plants were designed by BJIS and P2W in Israel and around the world.

P2W’s and BJIS’s treatment projects’ design cover a wide spectrum including simple earth lagoons, sophisticated earth lagoons, mechanical treatment of water and wastewater, biological treatment plants, nutrient removal plants, filtration, tertiary treatment of effluent, fixed-bed  technology, combined suspended and fixed-bed technology, MBR, chemical treatment of water and wastewater, sludge treatment technologies and more.

BJIS and P2W’s experts use sophisticated design tools and continuously participate in meetings, courses and conferences in Israel and around the world.

BJIS, as well as P2W as it’s Sister Company, have earned a local and world-wide recognition as a leading design firm for water and wastewater plants.


3. Sludge Treatment

Every wastewater treatment plant produces sludge that entails withdrawal, digestion, volume reduction and disposal.

Due to its complexity, sludge treatment constitutes the highest challenge to designers and operators of waste water treatment plants.

Throughout years of operation, BJIS have designed many sludge treatment facilities, covering a wide range of technologies, from the very simple earth lagoons sludge disposal to the state of the art sludge thickening, pasteurization, digestion and dewatering, collaborating with P2W with its expand knowledge on water, wastewater and river treatment technologies.

Our designs also include innovative methods for dewatering sludge conveyance and storage.


4. Wastewater Conveying and Pumping

Reliable wastewater systems are always necessary to protect drinking water sources and public health.

Wastewater sewerage systems typically consist of sewage net (varying from a street pipe to a main interceptor) and pumping stations.

BJIS and P2W have gained outstanding experience in the design of sewerage systems including very large diameter interceptors (up to 2.5 m), pipe jacking, sewage pumping stations of all sizes and more.


5. Hydroelectric Plants and Bio Gas Utilization

Hydro-Electric and Bio-Gas utilizations share common aspects by utilizing a natural source or a by-product producing valuable source of energy, and in many cases, preventing environmental pollution.

Over their many years of collaboration BJIS and P2W designed several co-generation projects utilizing bio-gas and producing heat and electricity. The size of the electrical output of these projects varies between 0.5 MW to 9 MW.

BJIS and P2W also design Hydro-Electric plants in several configurations, including the “one way” configuration, in which water are taken from a river (As mentioned, river treatment is one of P2W’S expertises) and conveyed to turbines and “pumped storage” configuration (in which the same water is used to produce electricity during peak-demand time and pumped to a higher reservoir during low-demand time).

6. Storm Water and Drainage Systems

The storm water system is a key factor in environment development of  urban and rural areas.

The system consists of conduits and drains, and outfalls to the main waterways. The drainage system is based on water sensitive urban planning (WSUP) and water sensitive urban design (WSUD).

BJIS and P2W have developed modern network analysis methods and software tools to design cost-effective and optimized water storm projects.
