AbstractPDAM Surya Sembada Surabaya City is a regional company authorized to produce and distribute water to customers. Utilization is not only limited to household needs, but also for public facilities. Along with the growth of clean water, of course, it will increase as well. This Final Project will explain the calculation of the reliable discharge of PDAM Surya Sembada Surabaya City in the Zone 5 area of West Surabaya Region. It also analyzes population growth projections using the Arithmetic and Geometric methods and calculates water needs, so that the water needs of PDAMs in Zone 5 can be identified. West Surabaya Region in the next 10 years, namely in 2028. After knowing the reliable discharge and water needs of PDAMs in the Zone 5 area of West Surabaya Region, the water balance can be known. PDAM water demand in the Zone 5 region of West Surabaya Region in the next 10 years, namely in 2028, is 3,914.59 liters / second smaller than the current mainstay discharge based on data from PDAM Surya Sembada of Surabaya, which is 3,955.99 liters / second. This means that the mainstay discharge of PDAM water for customers in the Zone 5 region of West Surabaya Region is able to meet water needs until 2028. AbstrakPDAM Surya Sembada Kota Surabaya adalah perusahaan daerah yang berwenang untuk memproduksi dan mendistribusikan air kepada pelanggan. Pemanfaatannya tidak hanya terbatas untuk keperluan rumah tangga, tetapi untuk fasilitas umum juga. Seiring dengan pertumbuhan air bersih tentu saja akan semakin meningkat pula. Tugas Akhir ini akan menjelaskan perhitungan debit andalan PDAM Surya Sembada Kota Surabaya di daerah Zona 5 Wilayah Surabaya Barat. Selain itu juga menganalisa proyeksi pertumbuhan penduduk dengan menggunakan metode Aritmatik dan Geometrik serta menghitung kebutuhan air, sehingga dapat diketahui kebutuhan air PDAM di daerah Zona 5. Wilayah Surabaya Barat 10 tahun kedepan yaitu pada tahun 2028. Setelah diketahui debit andalan dan kebutuhan air PDAM di daerah Zona 5 Wilayah Surabaya Barat, maka dapat diketahui keseimbangan airnya. Kebutuhan air PDAM di daerah Zona 5 Wilayah Surabaya Barat 10 tahun kedepan yaitu pada tahun 2028 adalah 3.914,59 liter/detik lebih kecil dari debit andalan saat ini yang didasarkan dari data PDAM Surya Sembada Kota Surabaya yaitu sebesar 3.955,99 liter/detik.

The limitation to get clean water causes the community to utilize the existing water resources. One of the villages needs clean water during the dry season in Mojo Village Padang District, Regency Lumajang. The need for clean water was increasing as the population growth. The population of the Mojo Village was 3,901 people. The needs of clean water were supplied from Jirun wellspring. The Jirun wellspring was located 20 meters lower than a residential area. The government of Lumajang Regency installed a hydrant pump to solve the problem for distributing the clean water from Jirun wellspring to the residential area. The flow rate of Jirun wellspring reached 22.91 l/s. The index of clean water criticality was 3.44% namely “uncritical” that indicated Mojo Village was abundant water availability.

Important Basis

The use of remote sensing to determine water needs has been successfully applied by several authors to different crops, maintaining, as an important basis, the relationship between the normalized difference vegetation index (NDVI) and biophysical variables, such as the fraction of coverage (fc) and the basal crop coefficient (Kcb). Therefore, this study quantified the water needs of two varieties of coriander (UNAPAL Laurena CL and UNAPAL Precoso CP) based on the response of fc and Kcb, using remote sensors and a water balance according to the FAO-56 methodology. A Campbell Scientific meteorological station, a commercial digital camera and a portable spectro radiometer were used to obtain information on the environmental conditions and the crop. By means of remote sensing associated with a water balance, it was found that the water demand was 156 mm for CL and 151 mm for CP until the foliage harvest (41 d after sowing); additionally, the initial Kcb was 0.14, the mean Kcb was 1.16 (approximately) and the final Kcb was 0.71 (approximately).

ABSTRACT The evapotranspiration process is critical to studies on the water balance and water demand of crops and can be determined by several methods. A widely-used method, despite its high installation costs, is weighing lysimeters, which consists of a box over a balance connected to a load cell that monitors variations in the soil-water-plant-atmosphere system. The aim of this study was to develop and calibrate six weighing lysimeters (with dimensions of 1.5 x 1.5 x 1.2 m each) by high precision load cells, testing their ability to measure water mass changes in field conditions and cultivated with common bean (Phaseolus vulgaris L.), in the city of Tangará da Serra, in the state of Mato Grosso, Brazil. All lysimeters showed coefficients of determination higher than 0.99, as well as Willmott indexes, correlation and high confidence indexes, indicating that the equipment is suitable for measuring mass variations in water balance and evapotranspiration studies, representing the reality which occurred in the field.

Sustainable Water Supply

The city of Calgary has been one of fastest growing cities in Canada in recent years. Rapid population growth and a warming climate trend have raised concerns about sustainable water supply. In this study, historic climate, stream flow and population data are analyzed in order to develop models of future climate trends and river-water resource availability. Daily water demands for the next 60 years were projected using the relationship between daily maximum temperature and water demand under simulated climate and population growth scenarios. To maintain sustainable growth Calgary will require water conservation efforts that reduce per capita water use to less than half of the current level over the next 60 years, an interval when the civic population is expected to be doubled.

Demand Projection

This research projected the citizens and water demand in 13 regencies/cities in South Kalimantan Province from 2013 to the next 20 years. The results of the project were compared with the intake capacity to meet the demand in upcoming years. In projecting the population growth, five methods were used, namely aritmethic method, geometric method, linier regression method, exponential method and logarithmic method. The most appropriate method for projecting the population growth is the method which has the minimum value of standard deviation and the correlation value close to 1. Water demand was calculated based on some factors, such as the average water demand, the maximum level of water demand, and the water demand at peak hours. The existing intake capacity was then compared with the water demand projection. In almost all PDAM (Munipical Tap Water Company) observed, the capacity of water processing installation could not fullfill the water demand at the peak hours. The adequate intake capacity of PDAM was only in Balangan regency and Banjarmasin city.
