Mmamashia

Mmamashia is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mmamashia rather than just read about it. In short: Mmamashia is a location in Botswana about 15 kilometres (9.3 mi) north of the capital city of Gaborone that is the site of the Mmamashia water treatment plant and master balancing reservoir. Waterworks The reservoir and plant are operated and maintained by the Water Utilities Corporation.

Key takeaways

Mmamashia belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mmamashia to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mmamashia from memory before moving on to harder problems.

Reference excerpt

Mmamashia is a location in Botswana about 15 kilometres (9.3 mi) north of the capital city of Gaborone that is the site of the Mmamashia water treatment plant and master balancing reservoir.

Waterworks The reservoir and plant are operated and maintained by the Water Utilities Corporation. The original source of supply was the Bokaa Dam, directly to the north. Implementation of the North-South Carrier water project in 2000 brought raw water to the plant from the Letsibogo Dam on the Motloutse River, much further north. After treatment the water is distributed to consumers in the Gaborone area. The reservoir is built of reinforced concrete, and has a capacity of 78,000 cubic metres (2,800,000 cu ft). The reservoir is closed to minimize loss through evaporation. As of 2003 the plant had capacity of 92,000 cubic metres (3,200,000 cu ft) per day. That year there was a shortage of water from the Letsibogo Dam, planned to be the primary supply. Instead, the plant was using water from the Gaborone Dam and water imported from South Africa. Phase 2 of the North-South Carrier Water Project brings additional water from the Dikgatlhong Dam. The additional water is expected to come available in 2014. The Mmamashia plant will be upgraded with an additional capacity of 45 Ml/d pre-treatment, due to eutrophication at Bokaa, and 45 Ml/day secondary treatment.

Social impact Thirteen families were forced to move for construction of the Mmamashia regulating pond, receiving compensation. Construction of a road from Mmamashia to Malolwane in the Kgatleng District was scheduled to start in June 2008, passing between the Matebeleng and Oodi villages. The government was compensating farmers who lost land. In May 2012 six families of squatters at Mmamashia with 37 children were evicted and their homes demolished by the Kgatleng Landboard. The residents said they had been allocated some of the land by Kgosi Molefi and the rest by Kgosi Linchwe, and had occupied and farmed it for seventy years.

Worked examples

Example 1 — a first encounter with Mmamashia

Start with the simplest possible case. Write down what Mmamashia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mmamashia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mmamashia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mmamashia

In research: Mmamashia appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mmamashia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mmamashia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures in Botswana, Infrastructure in Botswana, Water treatment facilities, so understanding it makes those chapters shorter.
In everyday life: Look for Mmamashia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Mmamashia in simple terms?

Mmamashia is a location in Botswana about 15 kilometres (9.3 mi) north of the capital city of Gaborone that is the site of the Mmamashia water treatment plant and master balancing reservoir. Waterworks The reservoir and plant are operated and maintained by the Water Utilities Corporation.

Why does Mmamashia matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Mmamashia?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
