Urbinsight, Lima, Peru

Urbinsight Lima is a multi-year project of the Organization of American States’ Sustainable Communities Program. Facilitated by USA based nonprofit Ecocity Builders, the project offers a proven holistic urban systems assessment approach and process. To date, the Urbinsight Lima project is raising awareness and guiding decision-making for more efficient water use, reuse, conservation and watershed management in Lima.

The EcoCompass, Urbinsight’s educational platform, features a full suite of urban system research and training modules including spatial and non-spatial technologies advanced through an integrated and customizable set of classroom lectures and seminars, labs, and workshops. These materials have been developed by Ecocity Builders and adapted for local implementation with an emphasis on a Participatory Action Research framework. In Lima, the local focus is on water.

With a rapidly growing population of almost 10 million, Lima is home to one third of Peru’s population and is the third-largest city in the Americas, behind São Paulo and Mexico City.

Supply and access to fresh water is one of Lima’s primary challenges. The city landscape is prone to earth tremors and flash floods that can cause water-fueled landslides known as “huaycos.” Most recently, the huaycos of 2017 left Lima citizens without a reliable water supply for nearly three weeks. In some districts, access to running water is still limited to under 30 minutes per day.

The project is helping Lima assess conditions and risks in impacted districts and neighborhoods by collecting and sharing information on water resource systems and generating original community-level data to complement official government source data. Working with local universities, governments, community groups and citizens, the project is strengthening local capacity for data collection, analysis and action, and is supporting local initiatives related to urban sustainability, risk management, and urban resource accounting.

Focus Areas: San Isidro and Santa Eulalia

The two Lima study areas, San Isidro and Santa Eulalia, represent communities from both the lower and upper reaches of the Rímac river watershed, offering a powerful opportunity to leverage partnerships to better understand how water users are connected — through the health of the watershed and the water demands and behaviors of the users.

Citizen and student research provide a means for linking the urban downstream users with the rural upper watershed communities through mapping and data visualizations, collected through a unique participatory community data collection and information sharing processes.

Since 2012, PUCP’s Instituto de Ciencias de la Naturaleza, Territorio y Energias Renovables has been working with the small community of Santa Eulalia, located about 35 km east of Lima, on an integrated water resources management program. The town is situated in the basin of the Santa Eulalia River, a major tributary of the Rímac River, which supplies 75% of Lima’s water.

Santa Eulalia is focusing the Urbinsight implementation on watershed health and risk assessment of previously un-mapped sections of the local landscape, in addition to collecting data about water consumption and water quality.

The Municipality of San Isidro, a district located in central Lima, has implemented a number of plans and programs related to greening the city and promoting sustainability, such as bicycle lanes and tree planting.

The Urbinsight focus in San Isidro is on understanding the water sub system and local water infrastructure and use in order to make more informed proposals for water conservation, reuse and recycling, collection, and storage, as well as engaging neighborhoods and citizens in understanding their personal water consumption patterns and behaviors while raising awareness about conservation.

Urbinsight Project in San Isidro

Urbinsight Project in Santa Eulalia

Visualization of data only in the two neighborhoods of Santa Eulalia was not an intentional effort to demonstrate our focal areas — instead, this helps to demonstrate the lack of geospacial information for the District. Prior to our efforts little to no geospatial information existed for Santa Eulalia. Even basic items are not mapped such as streets, building lots, and bodies of water. Ecocity Builders collaborated with the PUCP course participants and municipal officials from Santa Eulalia to collect basic yet essential geospatial information for the two neighborhoods: Huayaringa and Pomaticla. Information such as Land Use, Parcel lots, streets, public spaces, parks, potential distaster relief spaces, and more were collected and mapped using arcGIS. This information will now become part of the municipalities toolbox for understanding these neighborhoods and planning for future development and risk aversion. The Municipal government has reviewed these maps created as part of the Urbinsight initiative and has let us know that they hope to conduct similar mapping exercises for all other neighborhoods within the district and to use these neighborhoods as precedent studies for planning these future initiates.

In order to better understand the district in a fine-grained context, the San Isidro focused course participants worked with Ecocity Builders and the Project data providers and the municipality to develop a neighborhood archetype map for the district, the first of its kind for Lima. These archetypes are an integral component of the Urbinsight methodology of assessing “neighborhood ecologies” in order to support more localized sustainability interventions with the participation and engagement of residents.

Lima Urbinsight Geoexplorer

Utilizing geographic data sourced from the Urbinsight Lima partners, participants assessed local conditions. Via additional research and auditing on the ground, they explored Lima’s water subsystems in context with the geographic analysis using tools to assess the urban metabolism of water as an “information system”.

San Isidro

District of San Isidro and its 16 Functional Areas.

● Neighborhood Archetype 1: In this archetype, there is a low density of houses and generally high economic strata. It is influenced by collective roads, the same ones that converge in their central parts, allowing for this location to be the home of commercial, residential, and zonal centers. In this archetype, the overall range of population density is between 70 and 140 people per hectare. Likewise, buildings are generally between 1 and 3 floors. 10 neighborhoods meet the criteria for A1.

● Neighborhood Arquetipo 2: The presence of the high-traffic metropolitan road axis (Av. Javier Prado) has made possible the presence of considerably tall buildings (15 or more floors) along Avenida Javier. The presence of housing as well as high density residential areas in both margins of the main roadway, in this archetype predominate the residential areas of medium, high, and very high density with high economic stratum. 1 neighborhood meets these criteria.

● Neighborhood Archetype 3: Large private recreational zone with extensive green space, bordered by very 24 high density housing (generally more than 200 inhabitants/ha). High economic stratum. Presence of buildings up to 30 floors. 1 neighborhood meets these criteria.

● Neighborhood Archetype 4: Public Recreational Area (park and garden), bordered in majority by low density housing with 3-floor buildings and high economic stratum. 1 neighborhood meets these criteria.

● Neighborhoods Archetype 5: Metropolitan commercial and financial zone, political-administrative center, tall buildings (up to 30 floors), floating population, high economic stratum, access to metropolitan roads such as: Vía Expresado de la República and Avenida Javier Prado. 3 neighborhoods meet these criteria

Urban Metabolic Information System (UMIS) Meta Diagram for Water / San Isidro

Background: Resources flow from the natural environment, into the built environment, and back again.

As urban subsystems become more complex and sophisticated, it is more common to cascade and loop the flows within the built environment, and thus minimize impact on the natural environment.

Because cities survive a very long time, it is not possible to assess flows over the life cycle. Instead flows are typically calculated for a period of one year. These total flows may then be normalized and expressed as a flow per day or per week or per season.

Sources

Most of the water for direct use other than drinking (residential and non residential) comes from the Rimac River watershed. Drinking supply for residents and visitors is imported as bottled water. The most common brands of bottled water are reportedly “San Mateo”, a Backus brand, and “San Luis”, a Coca Cola brand.

A large allocation to the water system is “Indirect” water – which includes water used to generate energy for residents and visitors in San Isidro. 72% of Peru’s total electricity generation comes from hydroelectric plants.

Rainfall is a minimal source of water in San Isidro. Nonetheless, San Isidro, like all of Lima, is particularly vulnerable to El Nino storms. In 2017, a record El Nino year, nearly 10 inches of rain fell between January and March, when, on average, the entire rainy season usually total just two inches.

Conversions

Most of San Isidro’s water allocation from the Rimac is treated at the City Water Factory of La Atarjea located in El Agustino, Lima. Green space irrigation in San Isidro utilizes partially treated water via a water channel, called Surco, sourced from the Rimac. Around 2% of the irrigation water comes from La Atarjea.

Demands

Water demand seems to be around the global average, but opinions and studies to date vary on the exact number and there is currently debate on these figures. The Urbinsight project will conduct an audit of residential and commercial use to get a more accurate calculation of of both volume and types of uses by residents and visitors, and by business and industry. The other major sector of demand is “indirect” which for now is a ‘catch all’ category that includes water used to make electricity and other products used by residents and businesses in San Isidro.

Reconversions

Wastewater is treated at the new La Chira plant which opened in 2016 as a service to Sepal, Lima’s Drinking Water and Sewerage Authority. This new facility added much needed capacity to Lima, and is expected to result in cleaner beaches and healthier coastal waters.

Sinks

The treated La Chira wastewater is discharged into the Ocean via a 3.65 km-long underwater outlet on the Pacific seabed. Water used in green areas and parks returns to the ground or is evaporated. “Indirect” water has a variety of sinks which include waste heat into the air for example.

Explore the diagram information by clicking on the sections above to learn more about the story of water as it moves through the district, from its source locations in the Rimac watershed, through the built environment (demands), and back to nature (sink).

Data for this diagram are courtesy of the Municipality of San Isidro. Three sectors are explored: Household/residential (R and R HH), Non Residential (NR) and Parks or Green Areas (P). The flows are shown in cubic meters per year.

Identificación de patrones de uso de agua para riego de áreas verdes en la residencial Santa Cruz del Barrio de San Isidro, Lima – Perú.

Identification of patterns of water use for irrigation of green areas in the residential Santa Cruz Neighborhood of San Isidro, Lima – Peru.

Overview

The surface area of the green areas of the district of San Isidro is 50,553.77 m². It is estimated that more than 3 million cubic meters of water are used for the irrigation of these areas, on average 78m³ per m², from previous studies it is known that more than 90% of this water comes from surface fresh water (irrigation channels).

The proposed research aims to identify the sources of irrigation water for green areas in residential Santa Cruz and determine the amount used by citizens and local government in this activity, in order to propose sustainable irrigation alternatives, prioritizing the reuse of water resources and the optimization of their use.
