Reactivating a 2,000-year-old water system in Jordan

Wed, Aug 15, 2018

In the Jordanian village of 聽Umm el-Jimal, Calvin senior Sarah Cok鈥攚orking through the聽Clean Water Institute of Calvin College (CWICC) and the alongside Jordanian experts and community members鈥攑articipated in a millennium-old engineering project.

Cok started at Calvin in engineering, but switched to an interdisciplinary major last fall, where she was able to combine her interests in civil-environmental engineering, environmental studies, and art history.

鈥淲hen I told [engineering] professor聽[David] Wunder about that,鈥 Cok said, 鈥渉e was like, 鈥楬ave you heard about this project? I think you鈥檇 be great for it.鈥欌 Wunder, who is director of CWICC, noted that Cok was 鈥渢ailor made for the work.鈥

An ancient answer to a contemporary problem

The village of Umm el-Jimal 鈥渉as seen five or six waves of civilization,鈥 said Wunder. Local Arab residents under successive Nabataean, Roman, Byzantine, and Islamic regimes built an extensive system of channels and reservoirs, which expanded as the town grew. By the twentieth century, much of the village鈥檚 water system was filled in with sediment, although inhabitants still relied on the functioning sections for water until the 1970s.

According to Cok, the modern Umm el-Jimal community now primarily relies on deep wells for water, but recently the wells鈥 aquifers have begun to dry up, forcing villagers to drill deeper.

Due to the Umm el-Jimal community鈥檚 need for an additional source of water, Calvin emeritus professor of archaeology Bert de Vries鈥攚ho has been working in Jordan for more than four decades鈥攃ontacted CWICC two years ago about reactivating the ancient water system.

With Wunder鈥檚 encouragement, Cok applied to travel to Jordan and work with CWICC on the project, helping to assess the feasibility of restoring the system and to draw up designs to meet the needs of the Umm el-Jimal community.

A vision in harmony with history

When she arrived in June, she found that the team was living in the village sheikh鈥檚 old house. The house had 鈥渁 big room where the girls slept, a big room where the guys slept, and then Bert de Vries had his own room with his wife,鈥 said Cok; 鈥淭here was also our big office space, which had giant ceiling fans, thank the Lord.

鈥淭he team members were all from different disciplines, which was really cool鈥 Cok added, 鈥淚 sat across the table from an anthropologist, a pottery specialist, Bert [de Vries, who is an archaeologist,] and a business professor.鈥

Cok alternated between office work, drawing up designs and writing reports; and working on-site, documenting existing channel conditions, carrying out a site elevation survey, and mapping locations for new channels. She also spent much of her time researching the appearances of both the ancient and currently functioning channels.

鈥淚t鈥檚 really important that [the new designs] are not copying the old ones, you want to be clear that you鈥檙e not trying to fake that they鈥檙e history,鈥 said Cok. 鈥淏ut you also need [the new designs] to be in harmony with the history, which sounds kind of flakey and weird, but is a super important part of this project.

鈥淎 聽lot of my role was to be an engineer, but be an engineer with respect towards preservation and site integrity,鈥 she added; 鈥淪o I drew up a bunch of different suggestions for what our channels could look like, and they pulled things from all these different designs while still looking clearly new and using [local] materials.鈥

Working towards a sustainable future

The community of Umm el-Jimal, according to Cok, is highly supportive of the project; both the mayor and the municipal engineers offered the team their assistance.

She noted that community members were also starting both an education initiative to 鈥渢rain teachers to teach students about sustainable water use, so that once we have all of the water system in place, people will be knowledgeable about how to best use and preserve it,鈥 and a company to eventually oversee the Umm el-Jimal project.

鈥淎 big part of this is that it needs to be sustainable without third party people coming in; that鈥檚 just a development thing,鈥 said Cok. 鈥淎s cool as it is we all get to work on this, it should be the community鈥檚.鈥

Since returning to the States, Cok has been working with Wunder on writing a scholarly paper about sensitive site design to help engineers be more effective at working in areas which are culturally, historically, and environmentally sensitive.

鈥淓ngineers, in my opinion, tend to overlook these things; if there鈥檚 a historic structure that they don't think will be useful to their purpose, they just get rid of it and build something new,鈥 said Cok, who argues in the paper that restoring and maintaining older structures is more sustainable and allows the community to connect better with its heritage.

Although she鈥檚 enjoyed being back, Cok is effusive about Jordan: 鈥淭he people in Jordan are amazing, they鈥檙e super hospitable, and I loved being there.

鈥淚 was invited to come back next summer, so we鈥檒l see,鈥 she said, laughing.
