GLOSSARY

Discharge Pressure

The pressure obtained at center line of pump discharge pipe using a calibrated gauge (psig). Discharge pressure is converted to feet and expressed as “Discharge Head”.

Brake Horsepower

The output horsepower of a motor to a pump; may also be used to refer to the required input horsepower to the pump itself.

Deep Well Turbine Pump

A turbine pump installed inside a well casing below the pumping water level in the well.

Discharge Head Head measured above center line of pump discharge pipe.

Drawdown The measured distance that a well’s water level changes from standing/static level to operating pumping level during observed test conditions.

Dynamic Head The sum of the pressure and the pumping head developed by a pump

Friction Head The head required to overcome the fluid friction in a pipe or water system

Friction Losses

Energy losses associated with moving water against rough surfaces. In water pumping applications, it is the water pressure lost as a result of contact between moving water and a pipeline or open channel.

GPM per Foot Drawdown

The ratio of capacity (GPM) to drawdown feet is useful in determining the well’s performance.

Head Alternate term for pressure. One pound per square inch (psi) = 2.31 feet of water head

Overall Plant The ratio of the water horsepower (the overall output of the plant)

6

or Pumping System Efficiency

to input horsepower (the power input). The overall output can also be defined as the amount of horsepower required to deliver the measured capacity (water gallons per minute) and the measured total head.

Pumping Water Level

The well’s operating water level below center line of discharge pipe as observed during test condition

Static Water Level The well’s water level obtained when pumping plant is at rest.

Suction Head Head measured above center line of pump suction intake. Most often obtained with calibrated bourdon tube pressure gauge (suction pressure) and converted to feet by conversion factor 2.31 ft. water/psi

Suction Lift The distance between pump discharge head and water level.

Total Head

The sum of the water head above and below the center line of the pump discharge pipe. For well applications, the Total Head is the sum of the Discharge Head and the Pumping Water Level. Total head is used in determination of water horsepower and pump performance.

Water Horsepower

The output horsepower of a water pump. It is the combination of flow rate and pressure.

1.0 Introduction 1.1 Background Energy Audit & Energy Efficiency Improvement gram Government of the Punjab, Pakistan with financial assistance from the World Bank, is implementing “Punjab Cities Governance Improvement Project (PCGIP)” for strengthening systems for improved planning, resource management, and accountability in five large cities of Punjab i.e. Lahore, Faisalabad, Multan, Gujranwala and Rawalpindi. The project utilizes a result-based approach and, consistent with this focus, the disbursement decisions to the city and its entities are based on achievement of pre-specified results, referred to as Disbursement linked Indicators (DLIs) which reflect priority elements in furthering the Government’s urban agenda, critical at the provincial level, within the existing legislative, regulative and policy framework of the Government. DLIs includes intermediate outcomes, incremental steps and results contributing to improved efficiency, effectiveness, accountability and service delivery during and beyond the project life by building capacities , system and processes . Disbursement Linked Indicator 4 (DLI -4) aims for improvements in own source revenue collection system that encourages the City Local Government (CDGs), Development Authorities (DAs) and Service providers (WASAs) to bring improved systems for revenue enhancement. This DLI is linked with the initiative of WASAs to carry out the Energy Audit for resources conservation and efficiency to improved service delivery, accountability and own source revenue. One of the proposed actions & initiatives to enhance revenue was to conduct energy audit of WASAs to reduce the power cost by various systematic analysis of the energy use and finding out the energy management opportunities. WASAs each year incur significant cost. It was Rs. 4,697 million in 2014 year for energy/Electricity bills, with an installed capacity of approximately 131 MW for 5,663 Million Gallons per Day (water management), which can be reduced through detailed energy audit and implementing its findings. In the context of existing scenario energy audit of WASAs is a technical and efficient way to obtain energy analysis and savings through improvements that optimize pumping systems of tube well stations and disposal stations to operate efficiently with significant cost saving. The Urban Planning and Management Services Unit, Pvt. Ltd. has assigned NEC Consultants Pvt. Ltd to conduct energy audits of WASAs in Punjab in five major cities of Lahore, Rawalpindi, Faisalabad, Multan and Gujranwala. This is the energy audit report of Zone-II of Gujranwala city. 1.2 Methodology The primary and secondary sources were used to collect data for different WASAs and pumps installed there. The Urban Unit provided information and contact detail of all the WASAs. An energy audit report template was developed to collect field data from each WASA subdivision. Prior to start the on field measurements of each subdivision, meetings were conducted with the respective WASA management and briefed them about the activity. The technical team then collected data by on field measurements of each pump and recorded in their energy audit report template. On the basis of this energy audit report template, The Urban Unit also developed Android based software to record data of each pump online. This data was also recorded on line in this Android based application.

8

On the basis of field measurements, efficiency of the pumping system was calculated and energy efficiency opportunities were identified. 1.3 Scope The scope of the this assignment is to conduct energy audits of about 1,600 fresh water supply and wastewater disposal pumps installed at different WASA stations in five major cities of Lahore, Rawalpindi, Multan, Faisalabad and Gujranwala. The detail of these pumps is given in Table-1.

- The energy audit report of each pump was prepared. - On the basis of each pump report, summary report of findings of each WASA

subdivision/zonewas prepared. - On the basis of each subdivision/zone summary report, one consolidated report of

each city for energy efficiency improvement opportunities of the WASAs was prepared.
