Kennis - Rioleringsbeheerders, stadsecologen en particulieren opgelet! Wist u dat in Nederland bijna een miljoen padden, kikkers en salamanders elk jaar in straatputten belanden? De in het verleden bedachte oplossingen werken vaak onvoldoende. Maar nu is er een goed werkende oplossing voor dit probleem waarmee negen van de tien dieren zichzelf binnen een etmaal uit hun benarde situatie kunnen bevrijden. Het probleem van amfibieën in straat- en trottoirkolken is al sinds 2012 bekend. Ook in kelderkoekoeken en leidingputten bij particulieren belanden vaak grote aantallen dieren. In de loop der jaren zijn oplossingen bedacht in de vorm van uitklimvoorzieningen. Hier kleefden echter te veel nadelen aan.

La gestión del agua es uno de los mayores desafíos a los que nos enfrentamos como sociedad. No solo hacer un correcto uso de ella, sino enfrentarnos al dilema de cómo mejorar nuestra relación con nuestros recursos naturales, en este caso los espacios fluviales. Entre los muchos problemas a los que se enfrentan Borgonyà por ser una antigua colonia industrial y por las barreras físicas que haya podido provocar en la cuenca, la contaminación es uno de los más importantes, en conjunto con la necesidad de mejorar una red de saneamiento unitaria que no garantiza un tratamiento adecuado a todas y cada una de las aguas que atraviesan el actual núcleo residencial. A través del parque de fitodepuración de Can Salvans, no solo se pretende mejorar la calidad del agua que devolvemos al río Ter, sino hacer de este espacio un lugar donde vecinos y visitantes se involucren en el ciclo del agua, y la creación de un área de valor paisajístico, social y ambiental.

Objective:This research aimed to design a drainage quality hydrodynamic model of the northeastern sector of Tunja (San-ta Inés neighborhood), Boyacá, Colombia, which was validated and calibrated by means of the mean square error method,where a comparison between the values observed in the field and the simulation results in the model was determined inorder to observe and analyze the effect of precipitation on pollutants before entering the treatment plant.Methodology:For this study, rainfall and water flow equipment were installed in the district. A validated and calibratedurban drainage model was created on the SWMM 5.1 software, which allowed a temporal hydrodynamic modeling of thesystem. In addition, samples were taken to determine the quality of the water arriving at the treatment plant and evaluatethe transportation of pollutants, as well as the possibility of hydrogen sulfide generation in the study area.Results:The results obtained with the model show that all pollutants generate drag in their concentrations. An excess ofthese values is observed within the total flow, which demonstrates the relevance of accumulation, washing, and transportprocesses, in light of the pollutant remnants causing the flow to decrease before the pollutant load.Conclusions:Our sampling indicates that it is necessary to analyze the coliforms present in wastewater discharges, as wellas the sulfate, nitrite, and nitrate values in the case of a specific discharge. The entity in charge of discharge control mustbe then informed.Financing:Universidad Santo Tomas - Tunja

Aquest treball posa en manifest tota la feina realitzada per complir l’objectiu principal: el disseny d’un algoritme per a la supervisió conjunta de la xarxa d’aigua de distribució i la xarxa de clavegueram, en el marc territorial de Els Condals, situat a Manresa. Per complir amb aquest objectiu, s’han definit dos procediments diferents però relacionats alhora. En un primer lloc, s’ha realitzat un estudi d’un conjunt de dades proporcionat per l’empresa d’aigües de Manresa. S’ha realitzat un anàlisi exploratori del conjunt de dades per comprendre què representa cada dada. Després, s’han realitzat modificacions sobre el conjunt de dades que han ajudat a trobar altres paràmetres, com per exemple les pèrdues de la xarxa de distribució d’aigua potable. Finalment, i utilitzant com a base la modificació de dades, s’han realitzat una sèrie de representacions de les dades que aportaven una ajuda visual a l’hora de identificar nous conceptes de la xarxa conjunta. Aquest tractament de dades ha resultat de gran ajuda a l’hora de definir els diferents comportaments que presenta la xarxa conjunta sota diferents estímuls, com poden ser pluges, accions humanes i pèrdues de la xarxa. Seguidament, s’ha realitzat un conjunt de simulacions sobre un arxiu que representa el model de la xarxa de clavegueram de Els Condals, utilitzant com a entrada del model les dades reals de la xarxa de distribució i altres dades calculades a l’estudi del punt anterior, comparant el comportament de les bombes del model amb el comportament real que presenten les bombes del sistema de clavegueram. En total, s’han definit 3 simulacions: la primera ha ajudat a comprendre millor l’espai de treball sobre el que s’han realitzat les simulacions. La segona ha servit per simular el comportament de les pluges i l’efecte que tenen sobre la xarxa d’aigua. La tercera, finalment, ha confirmat que no tota l’aigua proporcionada per la xarxa de distribució arriba a les bombes de la xarxa de clavegueram. Aquests dos proced

Para el 2050 nuestra demanda de agua aumentará 1% cada año, según la ONU y nuestros recursos irán disminuyendo. La escasez de agua no afecta solo a un sector o país, sino a la población global. La empresa prestadora de servicios de saneamiento, Emapa Huaral (Lima), diseñó e implementó el programa de educación sanitaria y/o ambiental. Este fue analizado por la presente investigación bajo una metodología cualitativa encontrando fortalezas y debilidades; así como diversas mejoras para hacer del programa, una iniciativa replicable en otros ámbitos., By 2050 our demand for water will increase 1% each year, according to the UN, and our resources will decrease. Water scarcity affect not only one sector or country, but the global population. The sanitation service provider company, Emapa Huaral (Lima), designed and implemented the sanitary and environmental education program. This was analyzed by this investigation, considering a qualitative methodology, and finding strengths and weaknesses; as well as various improvements to make the program an initiative that can be replicated in other areas.

Anthropic nutrient enrichment has become a major environmental issue in estuaries around the world, being the effluents of wastewater treatment plants (WWTPs) one of the main causes. Phytoplankton is, together with nutrients, a useful indicator for the ecological status assessment of estuaries due to its basal position in the food chain. The present study aims to evaluate the immediate effect of the cessation of the wastewater discharges on the environmental conditions and phytoplankton community along the eutrophicated Urdaibai estuary (southeastern Bay of Biscay). Thus, a short-term comparison of the physicochemical conditions and the phytoplankton abundance and community composition (by pigment analysis and microscopy) was carried out before and after the sewerage works. Results confirmed that the cessation of wastewater discharges had an immediate effect in the estuary, mainly noticed in the inner part. The abrupt decrease of ammonium (from 72.3 to 18.2 mu mol/L) and phosphate (from 3.5 to 2 mu mol/L) concentrations led to the improvement of the water status, reaching values lower than the "good" status threshold along the whole estuary. The phytoplankton community composition also showed and immediate reaction in the surroundings of the WWTP, with the chlorophyll b becoming the dominant secondary pigment in the area after the diversion due to the immediate and rapid increase of Eutreptiella sp. However, since the sampling-period of this study did not exceed a month after the cessation, a longer study-period is necessary, including interannual studies, to test the real effect of the sanitation works in the Urdaibai estuary.

A typical object on uniform sewer networks are relief chambers, which serve to regulate the flow of rainwater. Their task is to reduce the amount of rainwater supplied to the wastewater treatment plant and thus protect it from overload. These waters are a mixture of sewage and surface runoff water and therefore contain various contaminants. In the city of Trnava, reduced water quality was recorded in the Trnávka recipient. It is therefore necessary to determine the current state of these chambers and to determine whether they comply with current environmental regulations., Typickým objektom na jednotných stokových sieťach sú odľahčovacie komory, ktoré slúžia na reguláciu prietoku dažďovej vody. Ich úlohou je znížiť množstvo dažďovej vody privádzaných na čistiareň odpadových vôd a tým ju ochrániť pred preťažením. Tieto vody sú zmesou splaškových vôd a vôd z povrchového odtoku, a preto obsahujú rôzne kontaminanty. V meste Trnava bola zaznamenaná znížená kvalita vôd v recipiente Trnávka. Je preto potrebné zistiť aktuálny stav týchto komôr a zistiť či spĺňajú súlad s aktuálnymi environmentálnymi predpismi.

En el diseño y cálculo de redes de alcantarillado se ha obviado con demasiada frecuencia el problema de los sólidos transportados. Acumulación de sólidos y bloqueos de colector son una consecuencia de lo más habitual. Además, puede suponer, aparte de la reducción de sección útil para el transporte del flujo, un aumento de la rugosidad que puede generar sobreelevaciones del nivel en los colectores. En este trabajo se propone hacer un repaso a los diferentes criterios de autolimpieza de colectores de la literatura según diferentes aproximaciones y dependientes de la geometría del colector y del tipo de sedimento o concentración de sólidos en el agua residual. Dichos criterios se aplican un caso concreto de una red de alcantarillado existente para determinar los conductos más susceptibles a la acumulación de sólidos en la red y diseñar un correcto mantenimiento que sirva como ejemplo para su aplicación por parte de administraciones e ingenieros.

The Nibley City sewer collection system was designed in 2002 (SunriseEngineering, 2002) and installed in 2003. In 2014 the City completed a sewer collection system master plan because it had increased its sewer service area and increased building densities above what was originally planned for the system. The City desired to create a 2021 update for many reasons including: (1) The City is growing significantly, (2) Land-use densities have again increased in many areas of the City, and (3) An update to the sewer collection impact fees is needed. The City has hired J-U-B Engineers Inc. (J-U-B) to complete the 2021 update.

West Jordan owns the wastewater delivery system from the public right of way to the borders of the South Valley Water Reclamation Facility. New development is required to connect to a City system with adequate capacity to handle the new discharge.

The purpose of the “Development Requirements” is to provide information to the applicant which is necessary for the submission of a complete development application to the Lake Point Improvement District (LPID), and to identify additional documents and information required throughout the construction and acceptance processes. When the required information is submitted, LPID is better able to process and review your project in a timely manner. If the required information is not provided at the time of each submission, LPID will return the documents and submissions to the applicant, which will unnecessarily delay progress, review, and acceptance. This document is intended to assist the applicant in successfully completing each process. However, based on individual projects and circumstances, LPID may require additional information depending on the nature and complexity of the project.

Access to piped sewage in Latin America and the Caribbean (LAC) cities has been on the rise in recent decades. Yet achieving high rates of end-user connection between dwellings and sewage pipelines remains a challenge for water and sanitation utilities. Governments throughout the region are investing millions in increasing access to sewage services but are failing in the last mile. When households do not connect to the sewage system, the full health and social benefits of sanitation investments fail to accrue, and utilities can face lost revenue and higher operating costs. Barriers to connect are diverse, including low willingness to pay for connection costs and/or the associated tariffs, liquidity and credit constrains to cover the cost of upgrades or repairs, information gaps on the benefits of connecting, behavioral obstacles, and collective action failures. In contexts of weak regulation and strong social pressure, utilities typically lack the ability to enforce connection through fines and legal action. This paper explores the scope of the connectivity problem, identifies potential connection barriers, and discusses policy solutions. A research agenda is proposed in support of evidence-based interventions that have the potential to achieve higher effective sanitation coverage more rapidly and cost-effectively in LAC. This research agenda must focus on: i) quantifying the scope of the problem; ii) understanding the barriers that trigger it; and iii) identifying the most cost-effective policy and market-based solutions.

To close its infrastructure gap, Latin America and the Caribbean needs more than investment in new structures. It needs to become more efficient at investing in infrastructure and regulating a new range of services that have the potential to disrupt the energy, transport, and water sectors. The technological revolution makes a future with quality services possible, but not inevitable. This book offers policy options for countries to improve the access, quality, and affordability of services today, to ensure that they will be sustainable in the future, and to harness emerging technological advances for the benefit of all. This report aims to provoke discussion and further research on those many important issues and mark a path that helps the region move from structures to services and improve infrastructure for all.
